China launches two “test satellites”
China earlier today successfully launched two test satellites for “experimental verification of Earth observation technologies, its Long March 2D rocket lifting off from its Xichang space port in southwest China.
No word on where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China. The two satellites are part of the Shiyan family of satellites that have done rendezvous and proximity operations as well as surveillance of other satellites in orbit.
The leaders in the 2025 launch race:
126 SpaceX
58 China
13 Russia
12 Rocket Lab
SpaceX still leads the rest of the world in successful launches, 126 to 98.
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 or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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
