Nauka and ISS Problems

Thu Jul 29, 2021 8:02 pm

After a very delayed launch, plus issues getting and docking the newest Russian module, Nauka to the ISS, Nauka had an uncommanded thrusters firing today, causing the ISS to move out of orientation:

Following the docking of the Multipurpose Laboratory Module (MLM), named Nauka, to the International Space Station at 9:29 am EDT, Russian cosmonauts aboard the space station conducted leak checks between Nauka and the service module. At 12:45 pm, the flight control team noticed the unplanned firing of MLM thrusters that caused the station to move out of orientation. Ground teams have regained attitude control and the motion of the space station is stable.

The crew was never and is not in any danger, and flight controllers in Mission Control Houston are monitoring the status of the space station. Teams are also monitoring the impact to tomorrow’s launch of the Boeing Starliner spacecraft. Updates on the space station will be provided on NASA.gov and the agency’s social media pages.


As a result, the upcoming Boeing Starliner launch that was set for tomorrow has been pushed back while the ISS team conducts further checks on Nauka:

NASA and Boeing have decided to stand down from Friday’s launch attempt of the agency’s Orbital Flight Test-2 mission. Currently, launch teams are assessing the next available opportunity. The move allows the International Space Station team time to continue working checkouts of the newly arrived Roscosmos’ Nauka module and to ensure the station will be ready for Starliner’s arrival.


No word yet on when they will launch Starliner.

The ISS ended up at 45 degrees tilt. That's really serious.

Crew was ordered to close the Cupola windows, as well as shut the hatch towards the Nauka module. They also had to check for debris outside the station.

The Russians started battling the thrusters of the Nauka module by using the Progress thrusters. This could have ended up with a spin.

For now it seems stable, and the attitude is now back to normal.

Apparantly the Nauka module was left in Docking mode after it had docked. We don't know why yet.

Bad, worse still when you consider it's launch date was supposed to be in 2007.
Yet NASA get most flak for delays.

Yeah, not good. Sounds like it only stopped because Nauka ran out of propellant. Hopefully they can track down the cause relatively quickly. Otherwise they might not be able to use it for half the reason it was launched. :|

That's because you don't get transferred to a Siberian weather station when you criticize NASA...


Nauka has been a debacle from start to finish. Roscosmos is certainly not the reliable space partner it once was.

Yet Roscosmos does not face entities like Congress, different missions with a change of each administration (though not this time it seems), I've heard about quality control and corruption issues at Roscosmos, maybe this is to do with those.

Quality control issues have certainly seemed to plague them lately.
I don't know about corruption, but the stability of their government has not shielded them from quite drastic budgetary restrictions, which would have surely been at the origin of at least some of the reliability issues.

This event has delayed the Starliner launch.
