Proton flies last commercial mission
Scheduled for retirement by Russia and having its entire commercial business taken by SpaceX, Russia’s Proton rocket today successfully launched its last commercial mission.
The primary payload was a European communications satellite. The secondary payload is more significant as it is Northrop Grumman’s Mission Extension Vehicle (MEV-1), designed to grab defunct satellites that are out of fuel and bring them back to life using its own fuel and engines.
The docking mechanism of the MEV spacecraft allows it to link up with a spacecraft which carries no specialized rendezvous and docking hardware. According to Northrop Grumman, MEV, can use its proximity sensors and docking hardware to reliably attach itself to 80 percent of typical satellites deployed in geostationary orbit. The developer also said that after completing the work assisting the first spacecraft, the MEV vehicle could be undocked and moved multiple times during its more than 15-year operational life span to support satellites from other customers.
They plan to revive one of Intelsat’s satellites and operate it for five years.
The leaders in the 2019 launch race:
19 China
17 Russia
10 SpaceX
6 Europe (Arianespace)
The U.S. and China remain tied at 19 in the national rankings.
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

Wow, two historical events in one mission. The flight of the first MEV is really important for the future. Some symbolism here as a changing of the guard.
