China launches two science satellites with its Long March 11 rocket
The new colonial movement: China yesterday completed the eleventh successful launch of its Long March 11 rocket, putting two astronomy satellites in orbit designed to supplement gravitational wave research.
The satellites appear designed to look in other wavelengths at the region of sky from which gravitational waves are detected, and better pinpoint their location and nature.
This Long March 11 launch continues its perfect launch record. It uses solid rocket motors, derived from military missiles, which allow it to be stored easily and then launched quickly.
The leaders in the 2020 launch race:
33 China
23 SpaceX
13 Russia
5 ULA
5 Rocket Lab
5 Europe (Arianespace)
The U.S. still leads in the national rankings, 36 to 33, over China. And before anyone asks, yesterday’s SpaceX test suborbital flight of Starship does not qualify as a launch in these standings, as I only include successful orbital launches.
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
