It is nonetheless unclear why a Russian Soyuz spacecraft on the Worldwide House Station (ISS) sprang a leak final week, however one suspect has been dominated out: a strike by a Geminid meteor.
The Soyuz automobile, referred to as MS-22, sprayed its coolant into space on Dec. 14, the identical day that the annual Geminid meteor shower peaked. However there is not any causal connection, NASA and Russian house officers stated.
“We did have a look at the meteor showers that had been occurring,” Joel Montalbano, NASA’s International Space Station program supervisor, stated throughout a press briefing on Thursday (Dec. 22). “Each the trajectory crew in Houston and the trajectory crew in Moscow confirmed it was not from the meteor showers; it was within the mistaken course.”

NASA has been serving to Russia’s federal house company Roscosmos with the leak investigation, and never simply because each businesses are main ISS companions. This Soyuz introduced 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 used cameras on the station’s Canadarm2 robotic arm to examine the suspected leak space. The survey revealed a small hole within the MS-22, which is the obvious supply of the leak. However its origin stays a thriller, officers stated.
“We obtained some work to do with imagery to raised perceive if it was a meteoroid hit or if there was a {hardware} challenge, and that work is in entrance of us,” Montalbano stated.
The now-excluded Geminids are only one class of potential impactors. It is attainable, for instance, {that a} piece of space junk punched by way of the MS-22’s hull. Any object able to making such a tiny gap — it is roughly 0.8 millimeters broad — is just too small to be tracked from the bottom, stated Montalbano and Sergei Krikalev, government director of human spaceflight packages at Roscosmos, who was additionally on Thursday’s name.
A part of the continuing investigation is an evaluation of the MS-22’s flightworthiness. Roscosmos nonetheless wants to complete thermal analyses to find out how scorching it should get contained in the Soyuz throughout its Earth return, to see if it may possibly safely carry the three spaceflyers house.
It is unclear when such work might be carried out, although Russian house officers have beforehand indicated {that a} choice might come by the tip of the month.
If Roscosmos concludes that placing astronauts on the MS-22 is just too huge a threat, the company will purpose to fast-track the launch of the subsequent Soyuz. That automobile had been scheduled to carry off in mid-March from the Russia-run Baikonur Cosmodrome in Kazakhstan with three individuals aboard. Quick-tracking would contain launching it uncrewed just a few weeks earlier, maybe in late February, Montalbano stated.
In that state of affairs, the MS-22 would nonetheless come again to Earth, however with no passengers.
“If it is determined that it is an uncrewed Soyuz, Roscosmos would plan to return the present Soyuz on orbit and acquire the info to allow them to use that for future evaluations,” Montalbano stated.
