ISS after November 28, 2022 docking of unmanned Dragon freighter.
MS-22 is the Soyuz capsule that is leaking.
The Russian investigators yesterday concluded that the coolant leak on the Soyuz capsule docked to ISS was caused by an external impact, either by a meteroid or a small piece of space junk.
A decision on whether this capsule is still usable for manned flight will be made sometime in January. If not, Russia will move up the launch of the next Soyuz to ISS one month from March to February, but launch it empty. If so, managers will leave the schedule as is.
If the engineers determine the capsule is not flightworthy, it will mean however that until February, ISS is short one lifeboat. At present there are two Dragon capsules docked to ISS, one manned and one cargo. Both return to Earth with a habitable interior, but the cargo capsule is not intended for manned flight. In an emergency however it might be possible to use it.
This situation suggests that NASA should pay to get SpaceX to upgrade the cargo Dragons so that they could always be used as an emergency lifeboat.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history.

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
