Will probably be some time earlier than backup comes for an area station crew at the moment relying on a leaky Soyuz to get house.
Ought to the Soyuz MS-22 spacecraft be deemed unsafe after spouting coolant into space Dec. 14, two cosmonauts and a NASA astronaut might want to wait till February for a backup Soyuz to reach on the International Space Station (ISS), a Russian area official mentioned throughout a press convention Thursday (Dec. 22).
“Our subsequent crew … was scheduled to fly in the midst of March,” mentioned Sergei Krikalev, head of the Yuri Gagarin Cosmonaut Coaching Middle close to Moscow, through the livestreamed NASA press convention.
The brand new Soyuz on the bottom deliberate for that crew may as an alternative be launched empty to retrieve the three ISS crew members if they’re certainly stranded. However Krikalev mentioned it will possibly solely be “despatched up a little bit earlier … about two, three weeks earlier is on the most what we are able to do at this level.”

The reason for the outlet that brought on the leak remains to be beneath investigation, however one concept has been dominated out: it was not a part of the continuing Geminid meteor bathe, because the trajectory was within the incorrect route, Joel Montalbano, NASA’s ISS program supervisor, mentioned during the same briefing.
On Sunday (Dec. 18), NASA labored with cameras on the station’s Canadarm2 robotic arm. The survey discovered a small hole within the MS-22 that’s the doubtless explanation for the leak, however how the outlet got here to be is not but recognized.
“We bought some work to do with imagery to higher perceive if it was a meteoroid hit or if there was a {hardware} challenge, and that work is in entrance of us,” Montalbano mentioned. One other chance is a bit of space junk, however Krikalev mentioned such an object can be too small to trace from the bottom as the outlet was solely 0.8 millimeters vast.
If Russia certainly fast-tracks the following Soyuz to the area station, the broken MS-22 would come again empty. “Roscosmos would plan to return the present Soyuz on orbit and accumulate the information to allow them to use that for future evaluations,” Montalbano mentioned.
