China launches two military satellites with its Long March 7A
China today successfully launched two military satellites from its coastal Wenchang spaceport, using its new Long March 7A rocket.
The Long March 7 family of rockets will eventually replace the Long March 2 and 3 families. It can launch from the coast, thus eliminating the need to drop boosters in China’s interior. It has greater capacity. It also uses kerosene and oxygen, not hypergolic fuels that ignite on contact and are very toxic.
The leaders in the 2021 launch race:
49 China
31 SpaceX
22 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab
As there no more American launches planned this year, with this launch China wins the 2021 launch race, moving ahead of the U.S. 49 to 48.
This was the 129th launch in 2021. As there are three launches still scheduled — a Russian Angara test launch, a Ariane 5 launch placing Webb in orbit, and a Russian OneWeb launch — the year is likely end up tying or beating 1975 as the most active year in rocketry ever. The Chinese could also launch, as it has in the past done a lot of launches in December.
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
