Firefly Aerospace makes it to seven

Almost exactly one month ago, February 15th, I posted a notice to "Keep an Eye out for this launch this week" about a scheduled launch by Firefly Aerospace, with the funny/cute mission name "Stairway to Seven." Little did I know it would take them as long as it did to complete the mission, but complete it they did on Wednesday, March 11.  

"Mission success! Alpha Flight 7 achieved nominal performance and validated key systems ahead of our Block II configuration upgrade."  

The mission was the first successful launch for Firefly Aerospace after two successive launch failures in the last year. The first was at the end of April of '25, on a mission called "Message in a Booster," (second story in a short news story roundup) that was due to an anomaly just after the first stage shut down and dropped away from the upper stage.  This left the upper stage unable to complete the mission of putting an experimental satellite into orbit for Lockheed Martin.  The payload never made orbit. 

Alpha suffered an anomaly shortly after its two stages separated, which led to the loss of the nozzle extension for the upper stage's single Lightning engine. This significantly reduced the engine's thrust, dooming the mission, Firefly said in an update several hours after launch. 

Then, as they began preparations for "Stairway to Seven," in September of '25, the Alpha first stage exploded on the stand during a pre-launch test. This mishap added months to the mission development timeline as the company investigated a cause and got another booster ready for flight. The test-stand explosion was eventually traced to "a process error during stage one integration that resulted in a minute hydrocarbon contamination," which ruled out a design flaw and allowed them to return to work on a booster for this launch.

The three weeks of delays since the first announced February date for this attempt to launch "Stairway to Seven" were relatively typical things, mostly weather and an abundance of caution. The launch went off at 8:50 PM EDT on Wednesday, March 11, and from this viewer's standpoint, it appeared flawless with every major milestone ticking off just as called.

Now that they've successfully regained where they were with the Block I of Firefly's Alpha, they're going to throw it out - figuratively. They've been struggling to get through the past two mishaps before they switch over to working toward the first launch of the Block II Alpha. 

Alpha Block II will stand about 7 feet (2.13 meters) taller than its 96.7-foot-tall (29.6-m) predecessor and will feature upgraded avionics and power systems, as well as improved thermal protections.

[Wednesday's] launch was a significant step forward for Firefly, which has excelled in some areas of its space business more than others. Last year, the company's uncrewed Blue Ghost moon lander became the first private spacecraft to successfully complete a mission on the lunar surface, but Alpha has now managed full mission success just three times in its seven orbital launch attempts.

“Flight 7 served as a critical opportunity to validate Alpha’s performance ahead of our Block II upgrade, and this team knocked it out of the park,” said Adam Oakes, Firefly’s vice president of launch.
