Credit where credit is due, that headline is not my creation; rather it
belongs to Stephen Green at PJ Media (also known as VodkaPundit), who wrote, “That's One Small Walk for a Man (and a Woman)...” To further borrow his opening line:
The privately funded Polaris Dawn human space mission just kind of casually
reached the highest orbit in more than 50 years on Wednesday and on Thursday
conducted the first civilian spacewalks to just as little fanfare.
That's really the most succinct way of summing up the mission to date. To
borrow the frequently used line from the old commercials, "but wait! There's
more." While the first day of the mission marked the milestone of reaching the
highest altitude a crew has been since the last Apollo mission crossed that altitude on the way back to Earth, the last mission to orbit at that
altitude for an extended time was Gemini 11 in 1966. That flight was
crewed by Pete Conrad and Dick Gordon - both of whom have passed on. The two
would fly together to the moon on Apollo 12. Pete Conrad walked on the moon
while Dick Gordon had the job of being "the loneliest man in the universe" - the
Command Module pilot.
These two legends of the astronaut corps had their record broken by four young
and newly minted astronauts. The experienced two were commander Jared
Isaacman, billionaire tech entrepreneur, and pilot Scott Poteet, U.S. Air
Force, retired. The two new astronauts on their first flight were SpaceX
engineers Sarah Gillis, and Anna Menon. Both Gillis and Menon are on their first flight to orbit, got that altitude record, and Sarah Gillis got to do a spacewalk on her first trip to space! Anna Menon is serving as medical officer for the flight.
Wednesday, as the Polaris Dawn capsule was slowly increasing its orbital
apogee, they were also slowly and methodically having their air pressure
reduced while increasing the percent oxygen. This is done to reduce the amount
of nitrogen dissolved in their blood, to reduce the possibility of
decompression sickness. I know they were doing other things and not just sitting there noticing their
breathing, but I find no references to what they were doing.
While the walk was supposed to start earlier, 2:23 AM EDT, it didn't start
until just about four hours later: 6:12 AM. The start isn't when they open the
hatch, it's when they start bleeding the air out of the Dragon while doing
some functional checks on their suits. I watched both of them do their
spacewalks and they weren't dramatic - a good thing - but were functional
tests of different aspects of the suits, while supported by specialized hatch hardware designed just for this mission and known as "Skywalker." Similarly, the EVA
wasn't over when Isaacman and Gillis had completed their tests, it was
declared over when the cabin had repressurized and returned to the
conventional Oxygen/Nitrogen mix used. According to SpaceX, that was
7:58 AM EDT.
A detailed look at getting through the stages to take today's spacewalks.
From SpaceX.
I've been looking for links to videos of the two spacewalks themselves,
something on the order of the 10 minutes doing tests on Skywalker. There are
short videos on SpaceX's page on X.
A minute and change of Isaacman's
with his notable quote, "SpaceX, back at home we have a lot of work to do, but
from here it looks like a perfect world." Plus
a shorter one (that repeats) of Sarah Gillis' walk. The SpaceX page on X also has a long video (3 hrs 15 minutes) that you
could look around in
here.
I watched the
NASASpaceflight.com coverage, which was then posted as a 3 hr 19 minute video. They don't even approach
opening the hatch until almost 1 hr 54 minutes into the video (01:53:30).
Returning to where I started, with VodkaPundit's article, I think he ends it
really well, on a good note. All props to him for this perspective.
What Polaris Dawn and other SpaceX missions remind me of is NASA's Mercury
and Gemini missions of the 1960s. There were numerous technological
[hurdles] to be overcome and skills to be learned before the Apollo program
could take its final shape and send men to the moon.
...
NASA also had to learn about known unknowns, like whether radiation in space
would sicken or kill our astronauts in higher orbits. The men who performed
those Mercury and Gemini missions, from Alan Shepard on Freedom 7 to Jim
Lovell and Buzz Aldrin on Gemini 12, were pioneers in every sense of the
word. What they accomplished made Apollo possible. Without them, JFK's
challenge to land a man on the moon before 1970 would have been a largely
forgotten speech by a dead president.
Elon Musk wants to send humans to Mars (eventually including himself),
preferably beginning in 2028. SpaceX, like NASA in the '60s, has to learn
many lessons before that becomes possible.
SpaceX's genius play is that Musk has figured out how to get other people to
help pay for his R&D — and I don't mean your tax dollars. Polaris Dawn
was funded by Isaacman. While the billionaire refuses to say how much he
paid, I'd be shocked if it was anything less than $200 million, and I
wouldn't be too surprised if it turned out to be double that.
...
Isaacman is getting what he wants, and SpaceX is getting the data and
experience it needs to keep pushing the boundaries of human space travel.
So if anyone tells you that Polaris Dawn is just some rich man's stunt, you
can tell them the truth. It was one small walk for a man and woman, and one
giant leap for mankind.
