- Sierra Space successfully completes third test of its inflatable LIFE module
The module is intended for use in the Orbital Reef station that Sierra Space is building in partnership with Blue Origin and others.
- The flight recorder of Long March 2F is able to sustain 20,000G impact
Make sure you look at the picture of the flight recorder at the link. As Jay notes, “Just so you know, if this hits your house, it is not a box of KFC, but the flight recorder of a Shenzhou spacecraft.”
- Top Soyuz rocket manager claims they have completed design of a methane-burning rocket with a reusable booster
If you believe this is going to be built any time in the near future, I have a bridge in Brooklyn to sell you cheap.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Will there be a bravery medal for the first crew of Starliner?
With Boeing’s record they will have exhibited bravery!
(Do hope Boeing’s management realized how important a safe Starliner flight is to the company and let the engineers/technicians do what has to be done.)
Anybody up for dusting the rocket engine end table? Or, do you just do a 3 sec burn for that??
Sigh. Awarding the NASA MoH for a routine flight to ISS on a new spacecraft reduces it to the level of an Air Force Air Medal.
It’s interesting that on that picture of the flight recorder, both the model number and the production date are obscured.

Jeff Wright ,
You may appreciate this prospective launch company, as they use hydrogen for the fuel. Tim Dodd, the Everyday Astronaut, interviewed the company, Stoke Space:

They are using some hardware, methods, and technologies that have not flown before, but I hope that they do well despite these risks. The advantage of trying new things is that they can give an edge over the current competition. Rocket Lab and SpaceX have done well by doing things differently, and Blue Origin has a chance of also doing well. Even Virgin Orbit is able to launch for a much lower price tag to the customer than Orbital Sciences could do with its aircraft-launched Pegasus rocket.
We will have to see whether Stoke Space is able to handle its hydrogen fuel at low cost. They seem confident that they have enough people with current experience to work with the hydrogen in a cost effective manner.
