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.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

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.
