Main Engine Cut Off
Thanks to sghill over on the NASASpaceFlight forums who uploaded the Supplemental Environmental Assessment for SpaceX’s LZ-1 expansion plans. There are some really nice details hidden among a lot of boring details. Head over to the post if you want to download the full PDF.
SpaceX wrapped up their investigation into the Amos-6 explosion, and the news is mixed. I discuss their findings, their path back to flight, and some other 2016-2017 odds and ends.
Inmarsat, under regulatory pressure to get flying, decided to take a mid-2017 launch slot on Ariane 5, moving away from Falcon Heavy. Everyone thinks it’s a big deal, but for the wrong reason. And SpaceX’s Commercial Crew flights have been delayed, but we did find out that NASA’s Safety Technical Review Board approved their plan to load crew before fueling. That is a big deal.
The inevitable delay has been confirmed—approximately a six-month push–which is not surprising. The more important and meaningful revelation that came yesterday, per Jeff Foust of SpaceNews, was about the Falcon 9 propellant loading procedures as it pertains to crewed launches.
National Geographic posted a clip with fantastic behind-the-scenes footage from the first successful Falcon 9 landing. The emotion from every person who works at SpaceX is wonderful to watch—from the crowd behind mission control, to Gwynne Shotwell hugging and high-fiving anyone nearby, to Elon Musk running like a little kid after it lands.
Four months ago, we heard about the tricky situation Inmarsat is in with this satellite. It’s not a big surprise that they switched, and while it’s a bad look for SpaceX, it’s not that big of a deal. Yet.
Lately when I’ve been talking about political and financial tradeoffs made to sustain programs, I’ve been focusing on NASA’s exploration program, but the same things are true of Ariane 6.
All signs point to SpaceX nearing a return-to-flight mission for Falcon 9. I discuss what to watch for in the months ahead, and read some email.
Photos and videos were posted on the SpaceX subreddit of the ITS composite tank as it headed out to the destructive sea testing that we heard about from Elon Musk himself.
Signed about a month ago, this report from the FAA states that they’ve cleared the environmental concerns surrounding Falcon 9 landings at Vandenberg. Great timing, as SpaceX should be back up and flying soon.
