NASA TV, Rob Navias, updating the situation now. Thread⬇️
- Zvezda's hatch was opened and crew was in process of getting things up and running when at 12:45pm EDT, Nauka began firing uncontrolled. ISS 45 degrees out of attitude. NO DANGER TO CREW! 1/x
Progress thrusters were used to regain ISS nominal attitude. Station is in a good configuration now. Russia teams will working Nauka thruster issue. 2/x
Zvezda's systems picked up the issue and tried to correct, but this attitude correction maneuver was quickly switched to Progress. 3/x
Will need to get #Nauka back into range with Russian ground stations in order to inhibit the thrusters so they don't fire uncommanded again. 4/x
JAXA and ESA control centers were also monitoring the issue real-time. NASA and Russian Flight Directors on duty are in communication and talking through next steps. 5/x
Situation is still too new and developing in some cases to realistically talk about potential impacts to #Starliner's planned launch tomorrow at this point. 6/x.
Mission Control Houston thinks they've seen something off the Starboard SARJ. Asking crew to take photos of any potential debris or ice, etc. NO TELEMETRY indicates there's an issue, just double checking. 7/x
And nothing seen by the crew. "Nothing wrong with the SARJ," says Thomas Pesquet. 8/x
And they can't see anything from #Dragon either. So no damage seen and NOTHING seen floating away from ISS. NO indications of damage to ISS at this time. 9/x
Russian controllers intervened in the situation "very quickly" when #Nauka began to misbehave. 10/x.

Good things come to those (modules) that wait. It's LAUNCH DAY for the #Nauka science lab! The long-delayed module finally gets its time to shine. Liftoff is set for 14:58:21 UTC / 10:58:21 EDT form Baikonur

Article from Katya Pavlushchenko (@katlinegrey)…
With less than an hour to launch, let's take a trip through #Nauka's long history. There's a reason it's lovingly referred to as the "long suffering module."

A thread.... 1/x
#Nauka was originally a back-up to Zarya, in case that critical first ISS module was lost in a launch failure. Nauka, or FGB-2 as it was called then, was nearly complete when Zarya successfully launched in Nov. 1998. 2/x

Rocket Lab is about to provide a media update on the initial results/data of the successful recovery of the #Electron first stage on the #ReturnToSender mission.

Thread: 1/x
Peter Beck notes it's still early days. Stage back less than 48 hours. Really just starting to dissect everything. TEST COMPLETE SUCCESS... even more than we set out to do on this mission. This proved it is feasible and Electron CAN BE MADE REUSABLE! 2/x
Beck: Stage oriented itself and controlled heating very well. Recovery systems and pilot chutes deployed at Mach 2. Drogues slowed it down, and then mains "deployed lovely." Impacted ocean at 9 m/s, 1 m/s slower than expected. 3/x

Getting ready for @NASA's & @BoeingSpace's teleconference for #Starliner updates now that the Independent Review Team has finished their report. Thread:
Doug Levarro (NASA): Going to use today to "close out what we've been doing." <----- That better not mean no more updates, @NASA
Doug: 60 corrective actions identified. Will take several months to work through those.

Here's the statement on @BoeingSpace #Starliner issue & formation of an independent investigative board of issues on #OFT mission last month.

Interesting notes: .... 1/9
1. Docking to the Station was a contractual requirement for #OFT but - basically - NASA might waive it/allow contract to not be completely fulfilled in order to proceed to the Crew Flight Test. 2/9
"The uncrewed mission, including docking to the space station, became a part of the company’s contract with NASA. ... Although docking was planned, it may not have to be accomplished prior to the crew demonstration." 3/9
