- In fourth quarter of 2022 SpaceX placed almost as much mass into orbit as the entire rest of the world combined
For those who think upload mass the important metric, the graph at the link will answer many questions.
- Sierra Space touts its Vortex upper stage hydrogen-fueled engine, built in partnership with the Air Force
It is unclear on what rocket or spacecraft this engine will be used. Several years ago, early in development, the company said it would be for its Dream Chaser reusable mini-shuttle, but would use “green” fuels. I am not sure if hydrogen fits that bill.
- Engineers/scientists from China’s Academy of Sciences (CAS) go to ESA facility to help complete final tests on joint CAS-ESA solar mission
The mission, dubbed SMILE, will study the solar wind and its interaction with the Earth’s magnetosphere.
- Chinese atmospheric monitoring satellite shoots green lasers over Hawaii
The link includes a video of some of those lasers shots. The satellite, Daqi-1, was launched in April 2022. China claims it has no surveillance objectives.
- Europe joins the UK in investigating Viasat’s purchase of Inmarsat
The UK opened its own investigation in August 2022. In both cases, a decision against Viasat will likely hurt both companies, who are struggling to meet the new competition from the giant low orbit smallsat constellations like OneWeb and Starlink.
- Russia resumes prepping next Soyuz for launch
An inspection of the outside of the spacecraft’s cooling system found no damage or drilled holes. Expect the launch to occur before the end of February, relative close to its previous launch date of February 19th. As this is the lifeboat for three occupants of ISS, delaying its launch increases other risks.
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 print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
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
