Alpha Flight 7 achieved nominal performance and validated key systems ahead of Firefly Aerospace’s Block II configuration upgrade.

Mentioned as: nominalNarrative CapabilityMar 12, 2026It may have taken several delays, but Firefly successfully launched the "Stairway To Seven" mission on Alpha FLTA007! Apparently they did carry payloads for Lockheed Martin, but it sounds like these are hosted experiments rather then actual deployable satellites.

Alpha Flight 7 achieved nominal orbital insertion and deployed a technology demonstrator payload for Lockheed Martin.

The first two MVac burns on that Falcon 9 mission were nominal and deployed all 25 Starlink satellites to their intended orbit.

Mentioned as: nominalTechnical ProductFeb 3, 2026Interestingly F9 2nd stage de-orbit problems wasn't uncommon, 5 happened in 2020-21 alone (Starlink L4, L12, L14, L17, 2-1), plus of course Starlink 9-3 in 2024 during the primary mission. There's also Dragon Crew-9 where S2 de-orbited in the wrong zone.

During a Falcon 9 launch of Starlink satellites, the Falcon 9 second stage experienced an off-nominal condition while preparing for the deorbit burn.

The Falcon 9 second stage performed as designed to successfully passivate the stage after the off-nominal condition.

Mentioned as: nominalNarrative CapabilityFeb 3, 2026Yesterday, on the Starlink Group 17-32 mission, SpaceX had another failed deorbit burn. While the stage was unable to deorbit itself, the propellant was vented which did lower the perigee to 110km. SpaceX has already delayed several Starlink mission as they investigate the issue.

The ESA astronaut rehearsed nominal, contingency, and emergency scenarios across all phases of dynamic flight.

Mentioned as: Nominal SystemsNarrative GeneralJan 2, 2026RT by @Cosmic_Penguin: _-_ Diary of an ESA astronaut _-_ {USA 🇺🇸} Training weeks 77, 78 & 79 🧑‍🚀 Crew training with @SpaceX teams. We rehearsed nominal, contingency, and emergency scenarios across all phases of dynamic flight – over and over! Launch, free flight in orbit, docking, undocking, reentry, splashdown and recovery. Sometimes we train with only our instructors; other times we train with the Space X (MCC-X) and Houston (MCC-H) control center teams – mission director, “core”/“capcom”, systems engineers, etc. -> everyone who will be behind console on the day of the event! It is fascinating to see everyone working together. 🤩 One class with Don Pettit in the full scale ISS mockup. Thank you so much, @astro_Pettit, for sharing all your tips & tricks. It’s a privilege to learn from an astronaut with so much experience! ✅ Remote training with @JAXA_en teams to ensure we can work efficiently in Kibo, the Japanese module onboard the ISS. We refreshed our memory on some procedures, and deepened our understanding of some experiments. 🩺 Medical emergencies: we rehearsed key procedures. Practice is key should any medical issues arise. I also did another blood draw on myself! 📷 SpaceX/NASA/ESA: with my amazing commander @Astro_Jessica 🤩🤗 #εpsilon #crew12
