Hole in leaky Russian Soyuz spacecraft not induced by Geminid meteor
It truly is nonetheless unclear why a Russian Soyuz spacecraft at the Global Space Station (ISS) sprang a leak past week, but just one suspect has been ruled out: a strike by a Geminid meteor.
The Soyuz car or truck, recognised as MS-22, sprayed its coolant into place on Dec. 14, the similar working day that the annual Geminid meteor shower peaked. But there’s no causal connection, NASA and Russian area officials claimed.
“We did seem at the meteor showers that have been happening,” Joel Montalbano, NASA’s Worldwide Space Station plan supervisor, mentioned all through a press briefing on Thursday (Dec. 22). “Both the trajectory workforce in Houston and the trajectory workforce in Moscow confirmed it was not from the meteor showers it was in the erroneous route.”

NASA has been assisting Russia’s federal area agency Roscosmos with the leak investigation, and not just since both equally businesses are significant ISS associates. This Soyuz brought NASA astronaut Frank Rubio and two cosmonauts to the orbiting lab in September and is scheduled to return the trio to Earth in March.
On Sunday (Dec. 18), NASA employed cameras on the station’s Canadarm2 robotic arm to inspect the suspected leak spot. The survey revealed a little gap in the MS-22, which is the clear source of the leak. But its origin continues to be a mystery, officers mentioned.
“We received some do the job to do with imagery to greater recognize if it was a meteoroid hit or if there was a components challenge, and that work is in entrance of us,” Montalbano claimed.
The now-excluded Geminids are just one particular course of prospective impactors. It truly is doable, for instance, that a piece of place junk punched by way of the MS-22’s hull. Any object capable of earning this kind of a little gap — it’s roughly .8 millimeters huge — is also smaller to be tracked from the floor, reported Montalbano and Sergei Krikalev, executive director of human spaceflight applications at Roscosmos, who was also on Thursday’s simply call.
Component of the ongoing investigation is an assessment of the MS-22’s flightworthiness. Roscosmos still wants to complete thermal analyses to figure out how sizzling it will get inside of the Soyuz in the course of its Earth return, to see if it can properly have the three spaceflyers home.
It is really unclear when this kind of do the job will be finished, although Russian place officials have previously indicated that a decision could occur by the conclude of the thirty day period.
If Roscosmos concludes that putting astronauts on the MS-22 is way too large a risk, the agency will intention to quick-track the start of the subsequent Soyuz. That motor vehicle had been scheduled to lift off in mid-March from the Russia-run Baikonur Cosmodrome in Kazakhstan with three folks aboard. Rapidly-monitoring would involve launching it uncrewed a number of months before, potentially in late February, Montalbano reported.
In that situation, the MS-22 would even now occur again to Earth, but with no passengers.
“If it is really decided that it really is an uncrewed Soyuz, Roscosmos would program to return the current Soyuz on orbit and obtain the knowledge so they can use that for future evaluations,” Montalbano stated.
