SpaceX launches NASA X-ray telescope
Capitalism in space: SpaceX early this morning successfully launched NASA’s Imaging X-ray Polarimetry Explorer (IXPE), a small X-ray telescope designed to black holes and neutron stars.
The first stage, making its fifth flight, successfully landed on a drone ship in the Atlantic.
This launch, SpaceX’s 28th for 2021, extends once again the company’s all time record for the most launches in a year by a private company.
The leaders in the 2021 launch race:
46 China
28 SpaceX
21 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab
China’s lead over the U.S, in the national rankings has now shrunk to 46 to 45. The launch was the 121st in 2021, making this year tied as the seventh most active year in the history of space, a ranking that is sure to go up before the end of the year.
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

I listened to the NASASpaceflight commentary on the launch, and during a wind shear hold, they mentioned that SpaceX has demonstrated all the possible re-use cases for the F9/FH boosters:
1. Std F9 re-flown as FH side booster
2. FH side booster re-flown as std F9
3. FH core booster re-flown as std F9
FH core booster cannot be replaced by Std F9 booster or by FH side booster, due to special strengthening used in FH core design. In other words, it takes a specially-strengthened booster to handle the center position in the FH! Still a pretty impressive demonstration of manufacturing standardization and resultant use flexibility.
This makes me wonder how hard it would be for a five core Falcon superheavy to ease Raptor production woes. Most of the strengthening is done.
