BREAKING ... #Roscosmos to abandon "non-functional" #Soyuz MS-22, will send MS-23 robotically to bring the crew home (two Russians, one #NASA American).
#NASA "in concurrence" with #Roscosmos that "micrometeoroid debris" caused the #Soyuz coolant leak, no evidence of manufacturing defect.
#Roscosmos: Hole is in coolant radiator and in pipe providing coolant to the radiator. #NASA
#Roscosmos #MS-22 crew will remain on #ISS for "several months" until replacement #Soyuz arrives. #NASA
From Bill Harwood at #CBSNews: What if a disaster requires #ISS evacuation without a functioning #Soyuz?
#Roscosmos: #Soyuz not good for "nominal" re-entry but could be used in emergency. Could move "at least" one crew member to docked #SpaceX Dragon.
NOTE: The Dragon was designed to carry up to seven, but this one is configured for four seats. #NASA discussing with SpaceX.
#Roscosmos: Believe the hole was caused by micrometeorid debris, not orbital debris. Conducted simulations that led to this conclusion.
#Roscosmos and #NASA: Damaged #Soyuz #MS22 will be used to return equipment and experiments, targeting the usual Kazakhstan landing site. Temperature measurements will be taken in the cabin to see how it performs.
#Roscosmos: With crew aboard, humidity would be high and cabin temperature would reach low 40sΒ° C (about 110Β° F).
#NASA: If #Roscosmos cosmonauts were to fly back on #SpaceX Dragon, would have to move some equipment from #Soyuz #MS22 to Dragon and remove some cargo. This would only happen in an emergency.
The #NASA #Roscosmos telecon is over. Lots of "uninformed" questions towards the end. Big pressers attract media unfamiliar with the space biz. They tend not to know the subject matter and not listen to earlier answers.
@WordsmithFL thanks for this thread. Very informative.
Sounds pleasant, oof.
From #AP reporter: Could Boeing Starliner test flight have additional seats added to bring back crew?
#NASA: No, going to fly Starliner as designed. Will use currently docked #SpaceX Dragon, not the next one to fly later in 2023.
