Jared Isaacman gets senate approval as NASA Administrator

Today, Wednesday, Dec. 17, Jared Isaacman won senate approval to be administrator at NASA, a journey started just over a year, 377 days, ago. The final vote was 67 to 30, so not strictly along party lines. 

The source article at Ars Technica does a list of the major hurdles he had to overcome, but at ten items taking over half a screen, and in the final analysis, not that important now that it's over, it seems improper to just copy it here. As usual, go RTWT if you want the info. Instead, I'll use author Eric Berger's overview:

One of the biggest questions about Isaacman after his nomination in late 2024 was whether he had the political gamesmanship to run NASA. Few questioned his interest in space, knowledge of the industry, or flight experience. But he had no political experience. Could he handle the rigors of managing a tempestuous White House and fractured Congress?

The answer after he navigated the last year appears to be, quite clearly, yes.

Isaacman is younger than I thought - I had 48 or 50 filed away in my mind, but he's actually 42. That makes him the youngest NASA administrator ever. During the already-mentioned 377 days between his first nomination last December and now, he had to go through examination of his financial dealings, had to divest himself of perceived possible conflicts of interest, and go through the question after question periods in front of the Senate more times than if he was approved last year.

Regular readers may remember mention of a leak to the press of something he called Athena (second story here) that was an overview of his ideas about priorities in NASA once he took over. Eric Berger gives this perspective:

As the Project Athena plan clearly demonstrates, Isaacman has a good handle on the problems besetting NASA, an aging and increasingly bureaucratic agency. NASA can still do great things, but it has become almost infinitely harder since the heady days of Apollo six decades ago.

Isaacman has ideas to shake things up, but not to the extent of wanton change for the sake of change. It is clear from the interviews he has given to others, and in talking to him myself, that Isaacman is also a good listener. He wants to understand problems so he can work with others to apply thoughtful solutions.

NASA isn't the powerhouse it was in the past, as anyone who has paid attention for a while will know. About 20% percent of NASA's 17,500 employees a year ago took buyouts or early retirements. There have been layoffs at various facilities around the country. Their biggest problem (in my view), though, is bad decisions in the past, and the biggest of those is SLS and the Artemis program in general. The monster problem there is the high-stakes race with China to return humans to the Moon. Over the last year, that race has swung markedly in China’s favor to the point where two weeks ago, (Dec. 4) a former NASA Administrator said Artemis and the plans to get back to the moon simply won't work.

Looking over the last year, it would be easy to say NASA and Isaacman have lost more than half a year because of the withdrawal of Isaacman’s nomination in late May, when he was within days of bipartisan Senate approval. However, in the intervening months, Isaacman has made strong contacts within the US Senate and the White House. As part of the campaign to build support for his renomination, Isaacman emerges with considerably more political experience, a much closer relationship with Trump, and a deeper roster of contacts in his phone.

All of which is good, because for all of the fancy flying Isaacman has done to reach this point, his most difficult sorties lie ahead of him.

The MAVEN probe at Mars is looking worse than initial reports

Back last Wednesday, we learned that a NASA scientific research satellite in orbit at Mars called MAVEN (Mars Atmosphere and Volatile Evolution) had gone radio quiet instead of contacting Earth again. 

In the last 24 hours we've learned it's not just that the radio link isn't working, it's worse.

"Analysis of that signal suggests that the MAVEN spacecraft was rotating in an unexpected manner when it emerged from behind Mars," NASA officials wrote in the update. "Further, the frequency of the tracking signal suggests MAVEN's orbit trajectory may have changed."

Apparently, MAVEN is spinning around some untold axis affecting the radio signals from the probe. There are other spacecraft on and around Mars that can help, so they're not sounding desperate. At least, not yet.  

"For the next two weeks of scheduled surface operations, NASA is arranging additional passes from the remaining orbiters, and the Perseverance and Curiosity teams have adjusted their daily planning activities to continue their science missions," NASA officials wrote in the update.  

NASA's update explains:

Four orbiters at Mars, including MAVEN, relay communications to and from the surface to support rover operations. NASA’s Mars Reconnaissance Orbiter, Mars Odyssey, and ESA’s (European Space Agency’s) ExoMars Trace Gas Orbiter all remain operational.  

It's not sounding very good for MAVEN.

Small Space News Story Roundup 74

Because I'm guessing that except for a couple of launch service providers, the industry has started Christmas break. 

A Chinese-launched satellite came close to a collision with a SpaceX Starlink satellite

One of the nine payload satellites launched on December 9th from the Jiuquan Satellite Launch Center in the Gobi Desert came "too close for comfort" to the SpaceX Starlink satellite.

"As far as we know, no coordination or deconfliction with existing satellites operating in space was performed, resulting in a 200-meter close approach between one of the deployed satellites and STARLINK-6079 (56120) at 560 km altitude. Most of the risk of operating in space comes from the lack of coordination between satellite operators — this needs to change," Michael Nicolls, vice president of Starlink engineering at SpaceX, said via X on Friday evening (Dec. 12). 

Another article on the same site (Space.com) states that SpaceX launched their 10,000th Starlink into orbit around the middle of October. I think with 28 or 29 satellites per launch I've watched them add at least a hundred more to that total. Space.com goes on to say:

In 2020, for example, fewer than 3,400 functional satellites were whizzing around our planet. Just five years later, that number has soared to about 13,000, and more spacecraft are going up all the time.

Pardon me for the grade school-level arithmetic to follow, but I find this hard to believe. If we had 3,400 satellites in 2020 and five years later we have 13,000, that's pretty close to 10,000 in five years, which is what the previous link said about the 10,000th Starlink being launched. Either that or both numbers are wrong because they imply that no other country, company, or any entity has launched anything.

Starlink satellites avoid potential collisions autonomously, maneuvering themselves away from conjunctions predicted by available tracking data. And this sort of evasive action is quite common: Starlink spacecraft performed about 145,000 avoidance maneuvers in the first six months of 2025, which works out to around four maneuvers per satellite per month.

Atoms from Earth's atmosphere identified on the moon

New research has concluded that atoms and molecules from Earth's atmosphere have been traveling across space to settle on the moon for billions of years, solving a puzzle that has existed since the Apollo program.

In samples of lunar regolith brought back from the moon by Apollo astronauts, scientists have found puzzling amounts of volatiles, which in this case are elements such as water, carbon dioxide, helium, argon and nitrogen that have low boiling or sublimation points. Some of these volatiles are brought to the moon from the sun via the solar wind, but the abundances of these volatiles, particularly nitrogen, cannot solely be explained by the solar wind.

The puzzle of how these components ended up on the moon is a bit involved, but in the big overview, it was originally thought some of the volatiles have come from Earth, as particles leaking out from our planet's upper atmosphere when they receive a nudge from energetic particles riding the solar wind. It was believed, though, this could only have happened in the early days of Earth's history, before our planet had a chance to develop a strong global magnetic field. It was thought a strong field would block particles from escaping. This was eventually run through computer simulations which showed a strong magnetic field didn't stop the particles leaving Earth.

There are interesting details in the source (first link) but a bit long to lift and reproduce here. If you're interested, RTWT.

Final words to space.com.

This means that the lunar regolith could still hold a very long-term record of Earth's atmospheric history, which in turn could teach us about how Earth's climate, environment and even life has changed over billions of years. Furthermore, the insights gained don't have to be confined to our planet.

"Our study may also have broader implications for understanding early atmospheric escape on planets like Mars, which lacks a global magnetic field today but had one similar to Earth in the past, along with a likely thicker atmosphere," said Paramanick. "By examining planetary evolution alongside atmospheric escape across different epochs, we can gain insight into how these processes shape planetary habitability."

This is a big week

This is a personal big week. This is the 10th anniversary of my retirement, my last week and last day of working. That was Friday, December 18, 2015. The 18th is this coming Thursday. 

As I said that day, I started working full time in late 1975.  Before that, I worked part time while going to school.  From 1975 to 2025, I had been unemployed for 6 weeks.  It was '82, during the post-Carter recession, when Fed Head Paul Volcker raised the prime rate to 21.5% (at one point) to stop the near-runaway inflation of the late 70s.  Since then, I had been laid off, but generally left one job on Friday and started a new one on the following Monday.  

I started in college in the fall of '72, three months after high school, with intent to study biochemistry but never had a good feel for what was available in terms of where to work and what to do. I ended up dropping out of that program, got a job as an electronics technician based on what I learned as a hobbyist and started going to school at night for that. I worked full time and took two night classes per term until 1988 when I finally got my bachelor's degree. 

There's a saying everyone knows about "the best laid plans of mice and men" and it describes this part of my life. In high school, I was in all the "honors" classes, graduated with honors, had some recognition I don't remember the name of from the National Merit Scholarship Qualification test, and was accepted to both colleges I applied to. In my senior year of high school, my dad fell at work (US Postal Service), re-injuring an old injury from WWII and became disabled - wheelchair bound. Mom and dad had to tell me they couldn't pay my tuition like we had planned. So I went for some "discount knowledge at the junior college" - Miami Dade Junior College. Until they moved to the next county north and further disrupted life.

In my adult life, I never took more than a week long vacation while working and since retiring, we haven't gone anywhere for more than 10 days. We took a couple of trips but really nothing much, and I think our last trip was to the August 2017 Total Solar Eclipse. We went to a small city in Tennessee that was closer to the centerline of the eclipse path, called Goodlettsville. We drove up, 800 miles each way, spending one night in Chattanooga on the way up, and one just south of Atlanta on the way back. Yeah, we could have done each drive in one day but took it easy.  

Now that I sit down to tell the story, that's really just about all of it. We paid off our house early, and really tried to get into a good position financially so that we might be less likely to need to go back to work. It worked out well. The house was built in 1980 (IIRC - we bought it from the first buyer in 1984) so while it was built well, survived the various hurricanes and tropical storms well, it's still a 45 year old house. While I fight to keep hiring contractors to a minimum, every so often, I need to. We replaced the central Air system in 2020 - where system means not just the air conditioner itself, but the duct system as well keep. I need an expert for that. I mostly keep an eye on things. 

After I graduated Junior College we played with some goofy pictures. Here I am pondering a lawn sprinkler as if it's some sort of alien technology. I think this was in 1985, but I'd need to go find my degree or an old resume to verify that.

About that Geminid Metor shower

You may have seen a bit of a headline buzz about the annual Geminid meteor shower peaking. The peak is going to be tonight (Dec. 13-14), and the Geminid shower is typically considered one of the best of the year - if not the best. The general rule of thumb is that the best viewing is with the moon in its darkest phases, and moonrise is after 1:00 AM Sunday the 14th, local time - my local moonrise is 0134 ET. The phase is in the last quarter so the moon doesn't get much less light than this. All things considered, if your skies aren't cloudy, this could be a very good meteor shower to watch.  

If you're going to be watching visually, the standard advice is to get to the darkest skies you can.  Outside of town, if possible, which means in most the country you'll need to have planned this before the last minute. Of course, considering the time of year and local weather is important, too. Maybe even life threatening if you don't have adequate warm clothing, and maybe even a thermos bottle of hot coffee or tea. You know your conditions and weather better than I can say.

If you trace the bright streaks, you'll notice the streaks get shorter as you get closer to two brighter stars just right of center: those are Castor and Pollux, the two stars at the "top" of Gemini. The constellation stretches up and to the right in this picture. 

Of course, this is written from the perspective of watching the shower. If sitting up all night or until the early morning doesn't sound like fun, and you're also a ham or the radio aspects are more interesting to you, there's always Meteor Scatter.  I covered a lot about meteor scatter in that article, but not the details of how to set up a computer driven VHF radio to make contacts via meteor scatter. Unfortunately, that's too involved for you to set up everything if you aren't already. If you've already setup a station, and you're using WSJT-X or the Improved version, just click the MSK button, and it will change you to the default frequency and other settings.

I've posted screen captures from DXMaps before, and this one is from about 0220 UTC - less than 15 minutes ago as I type. Every dark blue line on this map was reported as a Meteor Scatter QSO, on or near the agreed frequency to hang out on and try for MS contacts: 50.260 MHz.

A less often talked about aspect of meteor showers is that they're typically usable for radio contacts for several days around the peak. This one, for example, will probably continue to provide contacts for at least another week, it's just the number of the rocks or grains of sand that cause the show and allows the radio contacts drops off. A benefit of radio is that you can make contacts well after sunrise or before sunset. Visually, you can only see the meteors while it's dark. 

Hungry Hippo is ready to fly

Rocket Lab announced Monday that the Neutron rocket’s innovative “Hungry Hippo” captive fairing has successfully completed qualification testing and is en route to Virginia's Wallops Island Flight Facility launch complex LC-3 in preparation for Neutron’s first launch. Neutron is Rocket Lab's entry into the Falcon 9 class of rockets and will be reusable. 

Neutron, though, operates rather differently from the Falcon 9. As you know, Falcon 9 drops its fairings, and after some time trying to catch the fairings with huge nets on offshore fishing-style boats, settled on dropping them into the ocean near a recovery vessel that then goes and pulls them out of the water. 

Neutron's first stage, by contrast, will open its top like a giant mouth to spit out the vehicle's entire second stage and payload, and will then close the two halves back together before descending back through Earth's atmosphere to land and fly again.

Video here, but it's tests of the opening and closing of the fairing, not an animation of a mission. 

Before departing Rocket Lab's California-based test facility, the fairing was exposed to 275,000 pounds of external force to simulate dynamic pressures during launch, rapid cycling of the open and close mechanisms to ensure faster-than-necessary operations, software integration and load forces exceeding 125% design requirements.

Once the fairing is incorporated with Neutron's first stage, Rocket Lab will perform a series of prelaunch tests, including a static hotfire of the nine Archimedes engines that power the reusable booster. Neutron will stand 141 feet (43 meters) tall with a 23-foot (7 m) diameter, and is expected to deliver up to 28,700 pounds (13,000 kilograms) of payload to low Earth orbit.

It has been a few years since Rocket Lab first started talking about developing Neutron. While Rocket Lab's main income source is the Electron, they seem to be a "Space 2.0" company. They have flown some reused boosters and engines, but don't seem to have made all the effort on reuse SpaceX has, which makes me assume it's probably less of an economic incentive for them. The Electron is a small satellite launch vehicle, just under 60 feet tall and putting a payload of 660 pounds to LEO. Neutron will be a big step up for them. Like Electron, Neutron has a graphite body. 

Rocket Lab has had 18 Electron launches in 2025 with 100% mission success. NextSpaceflight.com shows more launches: Saturday and next Thursday followed by a much larger bunch (seven) labelled No Earlier Than 2025. That puts them in a niche that features far more launches than United Launch Alliance, an even larger multiple of Blue Origin's launches than ULA's, but still a tiny fraction of SpaceX's.

In the wake of the Russian damaged pad

You'll recall that the story broke on Black Friday (last Friday in November) that in the aftermath of the successful launch of the Crewed Soyuz flight to the International Space Station, Roscosmos discovered some substantial damage to the launch pad. Briefly, a large platform under the rocket, with a mass of about 20 metric tons was apparently not secured prior to launch, and the launch vehicle's thrust knocked it into the flame trench.

Word broke today that NASA is moving up launches of SpaceX Cargo Dragons scheduled for later in '26 due to the uncertainties of not knowing when the Soyuz pad will be usable again.

According to the space agency’s internal schedule, the next Dragon supply mission, CRS-34, is moving forward one month from June 2026 to May. And the next Dragon supply mission after this, CRS-35, has been advanced three months from November to August.

To grab a paragraph from my original piece on this accident, Russia has "plenty of launch pads" in Russia, Kazkhstan and former republics of the USSR; the issue is that Site 31 at Baikonur is the country’s only pad presently configured to handle launches of the Soyuz rocket and the two spacecraft critical to space station operations: their manned Soyuz vehicle and their unmanned Progress cargo drones. 

NASA has more options than Russia, by far. It's probably fair to say that SpaceX doesn't need mentioning, since they do more launches than any other launch service in the world - and more than most of them combined. NASA has Northrop Grumman, and their Progress cargo vehicle. Progress has been out of service for a while and SpaceX has been launching Grumman's Cygnus cargo ships until the replacement for the rocket that Grumman has contracted for is delivered. Cygnus could fly on that booster as early as April '26. Don't forget Japan has a new cargo ship as well, HTV-X, which could deliver supplies in the summer of '26.

It is by no means certain that Russia will be able to fix the Site 31 launch infrastructure during the next four months. The average temperature during winter months is typically well below 0 degrees Celsius, and the country’s economic and industrial resources have largely been devoted to a war against Ukraine, rather than civil activities such as human spaceflight.
...
So for NASA and the international partnership that operates the space station, the damage at Site 31 is unlikely to become acute unless work is delayed into next fall—when Progress vehicles will be needed for propellant delivery and Soyuz spacecraft to relieve the crew in orbit.

A Martian Coincidence

Since the topic of moving toward more emphasis on going to Mars than to the moon, a follow-on story today underlines the reality that current satellites observing the Red Planet are not just the rovers on the surface, but others in orbit. An issue with all of them is that they're not recent launches and so they're getting older. Those satellites always have a rated lifetime and while many of those have operated far beyond the specified life, they all eventually wear out or fail in some other way. We need more of them.

NASA has lost contact with one its three spacecraft orbiting Mars, the agency announced Tuesday. Meanwhile, a second Mars orbiter is perilously close to running out of fuel, and the third mission is running well past its warranty. 

Ground teams last heard from the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft on Saturday, December 6. “Telemetry from MAVEN had showed all subsystems working normally before it orbited behind the red planet,” NASA said in a short statement. “After the spacecraft emerged from behind Mars, NASA’s Deep Space Network did not observe a signal.”

The oddity that jumps off the page at me is that MAVEN is said to be the newest of NASA’s three operational Mars orbiters - and it arrived at Mars 11 years ago: 2014. It launched 10 months before that in 2013 so it has been operational for more like 12 years than 11. When the newest probe is 11 years old, that doesn't sound like they have much of a chance to be useful to missions another 11 years into the future - or more.  

Built by Lockheed Martin, MAVEN has far outlived its original design life. More recently, MAVEN became an important node in NASA’s Mars relay network, passing signals between rovers on the Martian surface and controllers on Earth. If NASA is unable to revive the MAVEN spacecraft, the agency has two other orbiters that can pick up the slack. 

MAVEN is a child compared to other satellites observing Mars.

But NASA’s two other Mars orbiters have been in space for more than 20 years. The older of the two, named Mars Odyssey, has been at Mars since 2001 and will soon run out of fuel, probably some time in the next couple of years. NASA’s Mars Reconnaissance Orbiter, which launched in 2005, is healthy for its age, with enough fuel to last into the 2030s. MRO is also important to NASA because it has the best camera at Mars, with the ability to map landing sites for future missions.

What the groups behind a story like this are most concerned about is losing high speed data links back to Earth. Both of NASA's newer Mars rovers, Curiosity and Perseverance, have the capability for direct-to-Earth radio communication, but the orbiting relay network can support vastly higher data throughput. They're concerned that if those overhead satellites fail, much of the science data and spectacular images collected by NASA’s rovers might never make it off the planet.

NASA began planning for a dedicated Mars Telecommunications satellite more than 20 years ago, but cancelled the project in 2005. That's one of the reasons the rovers that can communicate with Earth directly; they have that hardware (or close to it) built on. The orbiting communications satellite concept appeared again this year in the “One Big Beautiful Bill” passed this July. 

The space agency has investigated using commercial relay services to replace the government-owned network currently in place at Mars. NASA awarded study contracts to Blue Origin, Lockheed Martin, and SpaceX in 2024 to examine possible data relay architectures.

... Lawmakers included $700 million for a “high-performance” telecom relay station in Mars orbit to be developed through a fixed-price contract. ...

The agency hasn't released any formal request for bids for such a Communications Satellite, but Blue Origin and Rocket Lab have let out some design concepts for a Mars telecom orbiter. 

Early signs that Mars is becoming the Next Big Goal

There has been a quiet, background story centered on making the moon less of a target with Mars the bigger goal. It's not like the idea of a lunar colony is going away, it seems to be that more and more people are seeing Mars as a more interesting goal. A major new report on the topic was released today (Tuesday Dec. 9) on the subject. It starts by addressing the major question: if we look at Artemis, years late and billions of dollars over budget, why would any country want to take on such a mission?

A new report published Tuesday, titled “A Science Strategy for the Human Exploration of Mars,” represents the answer from leading scientists and engineers in the United States: finding whether life exists, or once did, beyond Earth.

“We’re searching for life on Mars,” said Dava Newman, a professor in the Department of Aeronautics and Astronautics at Massachusetts Institute of Technology and co-chair of the committee that wrote the report, in an interview with Ars. “The answer to the question ‘are we alone‘ is always going to be ‘maybe,’ unless it becomes yes.”

If you go to that "report published Tuesday" link you'll find that it offers you a chance to buy a preprint of the report, or a paperback version (presumably later - after publication) but also has options of "Read Online" or "Download PDF." The report was researched and put together over the last two years, then published by the National Academies of Sciences, Engineering, and Medicine. In addition to Dava Newman named in that second quoted paragraph, the committee was co-chaired by Linda T. Elkins-Tanton, director of the University of California, Berkeley Space Sciences Laboratory.

“There’s no turning back,” Newman said. “Everyone is inspired by this because it’s becoming real. We can get there. Decades ago, we didn’t have the technologies. This would have been a study report.”

The goal of the report is to help build a case for meaningful science to be done on Mars alongside human exploration. The report outlines 11 top-priority science objectives. In order of priority, they are:

• Search for Life: Is there evidence of life, past or present, on Mars?
• Water and carbon dioxide: Understand how water and carbon cycles changed over time
• Mars geology: Better understand the geological history of the planet
• Crew health: How do humans fare psychologically, cognitively, and physically in the Martian environment?
• Dust storms: Understand the origin and nature of large dust storms on the planet
• Search for resources: Develop in situ resource utilization, focusing initially on water and propellant
• Mars and genomes: Determine whether Mars changes reproduction and genome function in plant and animal species
• Understand microbes: Are microbial populations stable on Mars?
• Martian dust: How harmful and invasive is dust on humans and their hardware?
• Plants and animals: Does Mars affect plant and animal physiology and development across generations?
• Radiation sampling: Better understand the level and impact of radiation on the surface of Mars

That strikes me as a rather thorough list and something that won't be solved on the first mission or the the first several missions put together. So how? Without a massive improvement in rocket performance, remember that missions to Mars need to launch near closest approach of Mars to Earth, the typical Hohmann transfer windows, which occur every 25 or 26 months. Returns typically seem to be thought of as, "they'll take however long it takes to get back to Earth." 

The committee also looked at different types of campaigns to determine which would be most effective for completing the science objectives noted above. The campaign most likely to be successful, they found, was an initial human landing that lasts 30 days, followed by an uncrewed cargo delivery to facilitate a longer 300-day crewed mission on the surface of Mars. All of these missions would take place in a single exploration zone, about 100 km in diameter, that featured ancient lava flows and dust storms. 

There seem to me to be issues that aren't addressed in that list, and potentially even bigger problems. Imagine sending a crew of astronauts to Mars and finding something in the environment is deadly. At first they don't know what killed off the crew member(s). Is it something toxic on Mars or a microorganism that killed them? Not knowing the answers to what it was, do you bring the survivors back to Earth and risk the entire population on Earth? 

Since the first missions sending robots to Mars, a principle our missions complied with was "planetary protection," which aims to protect both the bodies being studied (i.e., the surface of Mars) and visitors doing the studying (i.e., astronauts) from biological contamination. "Don't bring nothing, don't take nothing home." There are scientists that say people from Earth should not visit any other planet known to contain life. That could eliminate Mars missions before they ever take place. 

In response, there have been talks about leaving some areas alone, "pristine" and untouched by Earth. Considering how many places on Earth that were thought to be sterile have turned out to have "extremophiles" - organisms that live in environments that were thought to be so severe, life would never settle there, can there truly be pristine areas that something won't settle in?  Other than things like active volcanoes.

If NASA is going to get serious about pressing policymakers and saying it is time to fund a human mission to Mars, the new report is important because it provides the justification for sending people—and not just robots—to the surface of Mars. It methodically goes through all the things that humans can and should do on Mars and lays out how NASA’s human spaceflight and science exploration programs can work together.

“The report says here are the top science priorities that can be accomplished by humans on the surface of Mars,” Elkins-Tanton said. “There are thousands of scientific measurements that could be taken, but we believe these are the highest priorities. We’ve been on Mars for 50 years. With humans there, we have a huge opportunity.”

SpaceX's Latest Double Record Launch

This evening, SpaceX conducted the Starlink 6-92 mission at 5:26PM ET, which set two new records. Now one of them is almost a formality: it was the latest launch record on Cape Canaveral Space Force Station and every launch from CCSFS since the start of November has been a new record.  

The more interesting record is that Booster 1067 flew for a new record: flight 32. From our detached observing position (sitting here in front of the computer) it's hard to tell how smoothly the flight went but the landing looked to be inside the 10-ring. The last flight of B1067 was just short of two months ago, October 19th, and that's far from a record for turnaround time between flights, but we don't know if it was just the "next in line" or if there was something that had to be repaired. 

But as I've said many times, just use your best Grandpa Simpson / old man voice to say, "I remember when they weren't sure they could get 10 flights out of a booster and now they're going for 40."

Monday's launch from Florida was SpaceX's 158th Falcon 9 launch of the year and 510th reflight of a first stage since 2017. The company launched another set of 29 Starlink satellites from Vandenberg Space Force Base in California on Sunday (Dec. 7).

If you look at the SpaceX page on NextSpaceflight, you'll see eight launches of Falcon 9 missions with assigned dates and times up to December 28 and three more launches that just say NET (no earlier than) 2025. Eight launches would get them to 166 Falcon 9 launches in one year. Like today, a new world record, but any launch would be. Every launch is some sort of record. 

Pearl Harbor Remembrance Day musings

This is just a simple suggestion to take a few seconds to remember it.  Pay respect to the WWII vets who fought and died there 84 years ago this morning. There were 2,403 Americans killed and 1,178 wounded. If you're a praying person, send some thanks and gratitude to them.

Looking back I find I don't mention Pearl Harbor as often as other important days to remember. I'm going to guess it's because of it being a remote memory all my life. I was born after WWII. Dad suffered from injuries during training which kept him from deploying to Europe and left him impaired for life. 

Those of you of a certain age will remember how all sorts of special celebrations and special events in 1976 centered around it being the bicentennial. 2026 will be the 250th birthday of the Republic. The 250th anniversary is referred to as the Semiquincentennial, the Bisesquicentennial, or the Sestercentennial. I haven't heard or seen any of those words used yet, but I suspect once the calendar says 2026, we'll start to hear them. I'm guessing anyone who was older than about six years old in 1976 will have some memories of the bicentennial year. 

We're having a cool front come through and it's raining at the moment. It's not going to get cold, even by our rather warm standards; it's just going to be better than the last week or so and will be a couple to a few degrees under the averages instead of five or so above them. (Average high is 77 and average low is 58.) Tomorrow's forecast high is 75 and low 59. 

Hams Are Never Really Unified on New Technologies

While I tend to try new things and communications modes there are many hams who don't really pay attention to that. Whatever aspect of the hobby they started out with is what they continue with.  There's nothing wrong with that, "to each his own" as the ancient saying goes. When I was starting out, our radios tended to have vacuum tubes. More so transmitters than receivers, but the first radio I ever had in my shack was a vacuum tube-based transceiver that I built from a kit, a Heathkit HW-16. 

Today, I still have vacuum tube radios in the shack, but I rarely even turn the Collins KWM-2 on.  

For most of my career, I worked in receiver design and I probably spend more time paying attention to receiver design and how they perform than most hams. While I never worked on the software side, I had to take the classes on communications theory that those software guys took. The concepts behind optimizing a communications receiver in analog parts (transistors and ICs) are the same as doing it mathematically in processor. 

I posted a longer description of my station with some explanations back in June of '23 but that's not really what I'm here about. What this is about is what's behind a meme that I've run into online. 

CW is an abbreviation for Continuous Wave, which is ham talk for communicating by Morse code - as you can see the guy's hand on a Morse code key (in front of that are two other keys). FT8 is a digital communications mode that has become exceptionally popular in the few years since it was introduced into the ham world. It was developed by a small group of hams with advanced degrees and experiences in communications (comm) theory, led by Joe Taylor K1JT, a professor at Princeton University. The software used is called WSJT-X, and while there are other programs that tweak little things in the user experience the most important things are the details in how the software sends and receives. 

The translation of the meme is brutally simple: if you don't operate CW instead of things on your (ewww!) computer, you're a pussy. You're a girlie-man not a real man.

For the last several years, I've operated FT8 far more than any other mode: CW, voice (called phone) or any of the other dozens of digital modes. Over seven years ago, I posted the first mention of FT8 I ever posted, and at the bottom of that post is a graph that shows the growth of FT8 in the first year it became available, going from zero usage to over 50% of the traffic through a service called Club Log (that helps coordinate getting confirmation cards for hams). 

Let's talk about the communications theory here. Morse code or CW is a single tone, with information added by on/off keying - the familiar "beep-beep" sound of code. The bandwidth (BW) is determined by the on/off keying and the faster the keying (Words Per Minute), the more bandwidth the message takes. This is an iron law of Comm Theory - the more information you send in a given time, the more BW it requires. Morse code at 20 words/minute takes far less BW than talking, but transmits far less information per second. Video takes more BW than voice because it sends more information.  

The digital modes in WSJT are designed to be sent by modulating different tones that create a Single Sideband signal. Everyone operating FT8 on the same band uses a common frequency designated for users to meet. Let's say we're meeting somewhere in HF with an SSB rig. We send the audio tones from the computer's audio output to the transmitter and choose where in the transmit BW the output will be. My transmitter is set to allow a 3.0 kHz wide transmission, but the signal from WSJT is a tiny fraction of that width - on the order of 50 Hz. The signal is converted from the text on the computer to audio tones that are encoded with error correction information. In FT8, both stations in the contact take turns transmitting and receiving, 15 seconds each way, and a complete contact is about 75 seconds. 

CW wins in speed. A contact at 25 WPM or so (common in contests) can be under 15 seconds. The difference is that CW has problems with interference and interruptions that the signal coding and decoding from WSJT handles easily. 

There's a saying that goes engineering is the art of compromise because no solution is perfect everywhere. That's the case here. I've barely gotten into enough details about how the software works, what actual contacts are like and more. I have nothing against CW - until I started playing with WSJT, it was my favorite mode: I have Worked All States and DX Century Club with CW.

Small Space News Story Roundup 73

It has been several weeks since I ran one of these, but this weekend's stories are lining up well.

South Korea's space efforts are ramping up

There are three stories pointing this way in this week's Rocket Report from Ars Technica. 

The first story is about a satellite that was launched for Korea on a Vega C rocket by Arianespace. 

The Korea Multi-Purpose Satellite-7 (Kompsat-7) mission launched from Europe’s spaceport in French Guiana. About 44 minutes after liftoff, the Kompsat-7 satellite was deployed into SSO at an altitude of 358 miles (576 kilometers). “By launching the Kompsat-7 satellite, set to significantly enhance South Korea’s Earth observation capabilities, Arianespace is proud to support an ambitious national space program,” said David Cavaillolès, CEO of Arianespace, in a statement. (SSO = Sun-Synchronous Orbit)  

The story is novel for a couple of reasons, the first is that it’s the first time in more than two years that a satellite for a customer outside Europe has been launched by Arianespace. The backlog for the Vega C is almost entirely for European customers, private interests or governments. The Ariane 6, the heavier lift vehicle in the Arianespace’s inventory, has 18 launches reserved for the US-based Amazon Leo broadband network.  

The second story is that Korea has a homegrown launch vehicle called Nuri. 

Nuri took off from Naro Space Center on November 27 with the CAS500-3 technology demonstration and Earth observation satellite, along with 12 smaller CubeSat rideshare payloads, Yonhap News Agency reports. The 200-ton Nuri rocket debuted in 2021, when it failed to reach orbit on a test flight. Since then, the rocket has successfully reached orbit three times. This mission marked the first time for Hanwha Aerospace to oversee the entire assembly process as part of the government’s long-term plan to hand over space technologies to the private sector. The fifth and sixth launches of the Nuri rocket are planned in 2026 and 2027. 

I would have to assume the Nuri has so small a payload capacity that the Kompsat-7 was too big for it, or lifting it on their own launch vehicle wasn't a high priority.  

An interesting side note about Nuri is that it doesn't use methane or kerosene for fuel, as so many vehicles do. It uses a special form of kerosene called by several names: among them Jet fuel, aviation turbine fuel, or avtur, and Jet A-1.

The Nuri rocket has three stages, each with engines burning Jet A-1 fuel and liquid oxygen. The fuel choice is unusual for rockets, with highly refined RP-1 kerosene or methane being more popular among hydrocarbon fuels. The engines are manufactured by Hanwha Aerospace. The fully assembled rocket stands about 155 feet (47.2 meters) tall and can deliver up to 3,300 pounds (1.5 metric tons) of payload into a polar Sun-synchronous orbit.

Meanwhile, much like Honda, there's Hyundai

Back in June, Japanese automaker Honda made headlines launching a small, single stage test vehicle that returned to the launch site and performed a controlled landing.  

Now Korea's Hyundai has entered the space business - at least to develop the engines.

Meanwhile, South Korea’s space sector is looking to the future. Another company best known for making cars has started a venture in the rocket business. Hyundai Rotem, a member of Hyundai Motor Group, announced a joint program with Korean Air’s Aerospace Division (KAL-ASD) to develop a 35-ton-class reusable methane rocket engine for future launch vehicles. The effort is funded with KRW49 billion ($33 million) from the Korea Research Institute for Defense Technology Planning and Advancement (KRIT).

By the end of the decade … The government-backed program aims to develop the engine by the end of 2030. Hyundai Rotem will lead the engine’s planning and design, while Korean Air, the nation’s largest air carrier, will lead development of the engine’s turbopump. “Hyundai Rotem began developing methane engines in 1994 and has steadily advanced its methane engine technology, achieving Korea’s first successful combustion test in 2006,” Hyundai Rotem said in a statement. “Furthermore, this project is expected to secure the technological foundation for the commercialization of methane engines for reusable space launch vehicles and lay the groundwork for targeting the global space launch vehicle market.”

I should re-emphasize that the joint program is to develop a 35-ton-class engine, not a complete launch vehicle. Those two paragraphs are exactly everything the source had so there's no mention about a vehicle's size, number of stages, engines - or any of those important words. 

Still, all of the increased activity in the space sector from Korea that we've seen in just this one newsletter is great to see.

Congress warned Artemis “cannot work”

A really rare thing took place in front of a congressional subcommittee today. An expert witness, former NASA Administrator Mike Griffin, told them China is going to beat us to the moon and the plans to get there cannot work. More surprising was someone saying out loud that the reason the Artemis program is in such a deep hole is because of the perpetually late and over budget Space Launch System (SLS) and the recognition that the cost plus contracts they've been working under are a big problem. 

Let's back up a minute. 

Remember back in October when acting NASA adminstrator Sean Duffy did a review of the situation, partly to shake up everything? He got some things right but also got others wrong - in particular no focus on the cost plus contracts. But a month or six weeks before that, in the wake of Senator Ted Cruz hosting a "save the SLS" meeting in the Senate, Duffy was arguing we need to make Artemis III's mission the last SLS launch because we simply can't afford to use the SLS. In particular what Duffy said was:

If Artemis I, Artemis II, and Artemis III are all $4 billion a launch, $4 billion a launch. At $4 billion a launch, you don’t have a Moon program. It just, I don’t think that exists.

If I may be allowed to pirate that a little, I read that as, "$4 billion here, 4 billion there, pretty soon you're talking real money." 

As for what to do about it, Griffin said legislators should end the present plan.

“The Artemis III mission and those beyond should be canceled and we should start over, proceeding with all deliberate speed,” Griffin said. He included a link to his plan, which is not dissimilar from the “Apollo on Steroids” architecture he championed two decades ago, but was later found to be unaffordable within NASA’s existing budget.

That says the Artemis II SLS and Orion Capsule they just stacked for its February 5 mission will be the last SLS ever launched. I don't see how that could be relevant to whatever program replaces this, and if it's not relevant to whatever the program becomes, I say scrap it.

As I'm sure you're all aware, while there has always been a few percent of people who say we've never been to the moon, an argument I've noticed lately that I hadn't heard in the 1990s is along the lines of "things were so primitive in the 1960s, we barely had computers, how did we go then when technology today is so much better?" One of the reasons is people designing the Artemis programs thought it would be a waste to recreate the Apollo missions - send two guys to the moon for a day or two and come right back? That's silly. 

The idea was to build out a way to stay on the moon longer.  So they built the SLS rocket and capsule system (SLS = Shuttles' Leftover Shit) that falls short of the Apollo-Saturn V combination and kept band-aiding things onto that. A Lunar Space Station, um, "Lunar Gateway" that Apollo didn't need because they could get there for a couple of days, for example. Near Rectilinear Halo Orbits and more.

The most stringent criticism of the Artemis Program was offered by former NASA Administrator Mike Griffin. He has long been a critic of NASA’s approach toward establishing what the space agency views as a “sustainable” path back to the Moon, which relies on reusable lunar landers that are refueled in space.

Griffin reiterated that criticism on Thursday, without naming SpaceX or Blue Origin, and their Starship and Blue Moon Mk 2 landers.

“The bottom line is that an architecture which requires a high number of refueling flights in low-Earth orbit, no one really knows how many, uses a technology that has not yet ever been demonstrated in space, is very unlikely to work—unlikely to the point where I will say it cannot work,” Griffin said.
...
“Sticking to a plan is important when the plan makes sense,” Griffin said. “China is sticking to a plan that makes sense. It looks a lot, in fact, like what the United States did for Apollo. Provably, that worked. Sticking to a plan that will not work for Artemis III and beyond makes no sense.”

Aside from recognition and credit to the Commercial Lunar Payload Services, CLPS, which has been behind many of the small budget missions to the moon over the last several years, the other positive things to come out of the meeting came from Dean Cheng of the Potomac Institute for Policy Studies, who said NASA and Congress must do a better job of holding itself and its contractors accountable.

Many of NASA’s major exploration programs, including the Orion spacecraft, Space Launch System rocket, and their ground systems, have run years behind schedule and billions of dollars over budget in the last 15 years. NASA has funded these programs with cost-plus contracts, so it has had limited ability to enforce deadlines with contractors. Moreover, Congress has more or less meekly gone along with the delays and continued funding the programs.

Cheng said that whatever priorities policymakers decide for NASA,  failing to achieve objectives should come with consequences.

“One, it needs to be bipartisan, to make very clear throughout our system that this is something that everyone is pushing for,” Cheng said of establishing priorities for NASA. “And two, that there are consequences, budgetary, legal, and otherwise, to the agency, to supplying companies. If they fail to deliver on time and on budget, that it will not be a ‘Well, okay, let’s try again next year.’ There need to be consequences.”

“There need to be consequences?” This needs to apply to everything DC regulates/rules over and every agency doing it.

Chinese company's first launch goes well, but booster landing fails

China's first attempt to launch a reusable, orbital class rocket, had a lot to celebrate after the mission as the rocket successfully delivered the payload to orbit, but like the first launch of New Glenn, it was successful except for landing the booster. 

LandSpace, a decade-old company based in Beijing, launched its new Zhuque-3 rocket for the first time at 11 pm EST Tuesday (04:0 UTC Wednesday), or noon local time at the Jiuquan launch site in northwestern China. 

It's widely being reported that the Zhuque-3 (Vermillion Bird-3) was based on the Falcon 9, and it would be believable in any case, whether or not the rocket was being built in China, but let me give you a view of the "business end" of the system during initial liftoff and the start of climbing into orbit.

Notice the black triangular shapes? Those are the landing legs. Now the methane/lox combination is different from the F9's kerosene/lox combination, but a relatively minor change. That is, they probably didn't copy the F9's Merlin engines but either used an existing engine from elsewhere in China or they developed their own. The nine engines develop 1.7 million pounds of thrust, similar to but slightly less than the Falcon 9. The payload capacity is therefore a bit less than Falcon 9's as well. Zhuque-3 is able to lift 40,350 pounds to low Earth orbit (LEO), around 80% of the 50,265 pounds Falcon 9 can send to LEO. 

That view simply has "Falcon 9 copy" written all over it to my eyes. 

The rocket’s upper stage fired a single engine to continue accelerating into orbit. LandSpace confirmed the upper stage “achieved the target orbit” and declared success for the rocket’s “orbital launch mission.” This alone is a remarkable accomplishment for a brand new rocket.

But LandSpace had other goals for this launch. The Zhuque-3, or ZQ-3, booster stage is architected for recovery and reuse, the first rocket in China with such a design. Made of stainless steel, the first stage arced to the edge of space before gravity pulled it back into the atmosphere. After making it through reentry, the booster was supposed to relight a subset of its engines for a final braking burn before a vertical landing at a prepared location about 240 miles (390 kilometers) downrange from the launch pad.
...
Videos shared on Weibo, a Chinese social media platform, showed the final moments of the booster’s supersonic descent. A fireball enveloped the rocket at the start of the landing burn, and it impacted the recovery pad at high speed. But the rocket appeared to survive the most extreme aerodynamic forces of reentry, and it nearly hit a bullseye at the landing pad, situated in a remote dune field in the Gobi Desert.

Video of the last ~25 seconds of the flight here. 

“According to telemetry data, an anomaly occurred after the first stage initiated its landing burn, preventing a soft landing on the designated recovery pad,” LandSpace wrote on X. “The stage debris came down near the edge of the recovery pad, and the recovery test was unsuccessful. The specific cause is under further investigation.”

Those of us following new rocket developments would probably have been truly shocked if this vehicle had made the landing on its first try. New Glenn, of course, completely missed its first landing attempt and had to try again on its second flight just weeks ago. SpaceX, once they successfully landed a booster on land at the KSC and then landed on a drone ship offshore, put out a light-hearted video called "How Not to Land an Orbital Rocket Booster" which showed many attempts to land a Falcon 9 before finally accomplishing that. The current count of successful F9 landings is over 500. That has to make the next systems being developed easier to succeed with. 

China needs reusable rockets to keep up with the US launch industry, which is dominated by SpaceX, a company that flies more often and hauls heavier cargo to orbit than all Chinese rockets combined. There are at least two Chinese megaconstellations now being deployed in low-Earth orbit, each with architectures requiring thousands of satellites to relay data and Internet signals around the world. Without scaling up satellite production and reusing rockets, China will have difficulty matching the capacities of SpaceX, Blue Origin, and other emerging US launch companies. 

Without reusable rockets, China has turned to a wide variety of expendable boosters this year to launch less than half as often as the United States. China has made 78 orbital launch attempts so far this year, but no single rocket type has flown more than 13 times. In contrast, SpaceX’s Falcon 9 is responsible for 153 of 182 launches by US rockets.

Artemis II is fully stacked for launch

The SLS rocket and Orion capsule for the Artemis II mission to loop around the moon are stacked in the Vehicle Assembly Building at the Kennedy Space Center. Depending on where I look, the date can move around, and while being stacked doesn't necessarily mean it's ready to roll to the pad (39B) or that it's going to remain fully stacked, my guess is the funny date disagreement is probably due to a typo or "write-o" on somebody's notes. 

The important part is that the launch window for this mission opens No Earlier Than Feb. 5, 2026 at 8:09 PM which is just over two months from now.  NASA's news on that adds "no later than April" of next year.  

NASA’s Orion spacecraft, complete with its launch abort system escape tower, is now integrated with the SLS (Space Launch System) rocket in the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida. Following Orion stacking, teams completed testing critical communications systems between SLS and Orion, and confirmed the interfaces function properly between the rocket, Orion, and the ground systems, including end-to-end testing with the Near Space Network and Deep Space Network, which aid in communications and navigation.

“NASA remains focused on getting ready to safely fly four astronauts around the Moon and back,” said acting NASA Administrator Sean Duffy. “Our mission will lay the groundwork for future missions to the lunar surface and to Mars.”

Naturally, there are many tests coming between now and its launch to the moon. The vehicle will have to be rolled out to the pad, so they point out many of these tests can be done with the SLS/Orion stack still inside the VAB. This list from Exploration Ground Systems is a good starting point. 

A matrix of tests to be completed before launch in February.

In the big picture sense, this is another milestone on the way to launch. In one sense, it's "just another" milestone; from another viewpoint, it's important but they're all important.

Yet Another Slow to Zero News Day

So some old memes! 

Um... dude?  You might want to check your six.

Hope everyone had a nice Thanksgiving

It was a day to feel like things are pleasantly normal, rather than appearing to be in the opening moves of the Crusades 2.0. Thursday, we enjoyed what has become our traditional Thanksgiving celebration at my brother's house in south Florida. There and back combine into five hours of driving, but it's mostly the Florida Turnpike and I-95 so it's easier than driving in stop and go traffic. We spent from about 1:00 to about 6:00 PM with my extended family. We had a different day than last year's, which was at my nephew's over on the west side of the state. Both were nice, but the meeting at my brother's has been going on since that nephew was a teenager. 

Friday was our Thanksgiving here with just us. I smoked a turkey using a method I found years ago on Serious Eats; a combination of spatchcocking the turkey together with a dry brine and then smoking in my Weber kettle grill. It gives such a nice pink smoke ring in the meat that you just don't get with the electric smokers. I've done this basic recipe several times and it does produce a good turkey. I have fooled around with what I do a bit but I never know if the main difference is what I've done or how the turkeys are being raised. An aspect of this guy's recipe I never made the effort to follow is to add a tablespoon of baking powder into the dry rub. It's supposed to make the skin crisper and I didn't notice that at all.

Disclaimer: not this year's turkey. This picture is from 2021. 

The rest of my "usual activities" have been a bit on Abby's side of normal (Abby Normal...). Solar activity has been low and radio propagation has pretty low activity. I haven't bothered to turn the station on in days. I have a sale offer from the station software I use most (Ham Radio Deluxe) and I really need to spend a few hours working on that, trying to fix some odd issues I see when it automagically logs a contact for me. First step is to get the latest update installed - which I downloaded last weekend. 

We do have the potential for some improvement in propagation. A large sunspot group just rotated across the solar limb and started its one week voyage of pointing more directly at us each day until it's in the middle longitudes of the sun's face. Top story at SpaceWeather.com. In the last 24 hours, the Solar Flux has gone up from 120 to 160 and the planetary K index has increased from 2 to 3. 

It's worth watching a bit more closely.

Other than that, it has been fixing odds and ends around the house. We've been in this house 41 years. I don't think there's anything beyond big pipes in the slab that hasn't been replaced by now.

A typical Friday - in the world of the space industry

Today, of course, is the long-awaited and much-ballyhooed Black Friday - subject of at least a billion ads. In the corner of the world I like to keep track of, there were two things of note.  

• SpaceX launched the Transporter-15 Ride Share mission from Vandenberg this morning at 10:44 AM PT. SpaceX reports this was the 30th flight of Booster B1071. At 2345 UTC, SpaceX reports it had deployed all 140 payloads designed to separate from the rocket.
• In the aftermath of Thursday's Crewed Soyuz launch from the Baikonur Cosmodrome in Kazakhstan, which successfully carried Roscosmos cosmonauts Sergei Kud-Sverchkov and Sergei Mikayev, as well as NASA astronaut Christopher Williams, to the orbiting laboratory without incident, Roscosmos discovered some substantial damage to the launch pad. 

In a terse statement issued Thursday night on the social media site Telegram, the Russian space corporation that operates Soyuz appeared to downplay the incident: “The launch pad was inspected, as is done every time a rocket is launched. Damage to several launch pad components was identified. Damage can occur after launch, so such inspections are mandatory worldwide. The launch pad’s condition is currently being assessed.” 

Ars Technica is passing on additional reports to that quoted paragraph. 

However video imagery of the launch site after liftoff showed substantial damage, with a large service platform appearing to have fallen into the flame trench below the launch table. According to one source, this is a platform located beneath the rocket, where workers can access the vehicle before liftoff. It has a mass of about 20 metric tons and was apparently not secured prior to launch, and the thrust of the vehicle ejected it into the flame trench. “There is significant damage to the pad,” said this source.

While Russia has "plenty of launch pads" in Russia, Kazkhstan and former republics of the USSR; the issue is that Site 31 at Baikonur is the country’s only pad presently configured to handle launches of the Soyuz rocket and the two spacecraft critical to space station operations: their manned Soyuz vehicle and their unmanned Progress cargo drones.  

I get the feeling from reading what I can find is that I don't particularly doubt Roscomos' ability to fix the pad, and they say they have adequate spare parts to do it all. The issue is more along the lines of anything that might require more support from the government, which is rather tied up with their Ukraine issues. Much of that centers around the Progress cargo drones' trips to the ISS. Progress remains the only cargo vehicle to the ISS that seems rated to correct the ISS' orbit. SpaceX did that minor experiment recently that lifted the ISS but nobody that I saw would say they could take over for the Russians.

When I first ran into these stories I thought, SpaceX launched 140 ride sharing satellites, on the 30th flight of that booster, and it seemed impossibly easy, while Roscosmos almost lost the launch pad because someone didn't attach a 44 thousand pound (20 metric tons) service platform properly.  

Final words to Eric Berger at Ars Technica - as I often do:

The at least temporary loss of Site 31 will only place further pressure on SpaceX. The company currently flies NASA’s only operational crewed vehicle capable of reaching the space station, and the space agency recently announced that Boeing’s Starliner vehicle needs to fly an uncrewed mission before potentially carrying crew again. Moreover, due to rocket issues, SpaceX’s Falcon 9 vehicle is the only rocket currently available to launch both Dragon and Cygnus supply missions to the space station. For a time, SpaceX may also now be called upon to backstop Russia as well. 

 

EDIT 11/19 0815 ET:  The random brain fart generator threw one in that I didn't notice last night. Turned the original "44 thousand ton (20 metric tons)" to the correct 44 thousand pounds.
