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.

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.

#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.

#NASA: The main concern is with the temperature of the #Soyuz computer aboard. Not in a place that can be accessed by crew. Believe the temperature will reach "high 30s° Celsius (about 100° Fahrenheit).
