Russia might send up rescue ship for ISS crew

WASHINGTON

Russia is examining the flight worthiness of a Soyuz crew capsule docked with the International Space Station (ISS) that sprang a leak last week, and might need to send up a rescue vessel for stranded crew, officials said on Dec. 22.

The vehicle, known as MS-22, began spraying its coolant into space on Dec. 14, with dramatic NASA TV images showing white particles resembling snowflakes streaming out of the rear.

In a press briefing organized by the U.S. space agency, Sergei Krikalev, who leads human spaceflight programs at Russia’s Roscosmos, told reporters the damage was being assessed.

If a thermal analysis, which assesses how hot it will get inside the cabin, concludes MS-22 is unfit for crewed flight, then a scheduled launch of another Soyuz capsule in mid-March from Baikonur Cosmodrome could be moved up, and it would launch uncrewed, he said.

“They’re looking at late February to send up the next Soyuz vehicle,” added Joel Montalbano, NASA’s International Space Station program manager, who was also on the call.

If this were the case, the damaged spaceship would return to Earth without crew.

MS-22 flew Russian cosmonauts Dmitry Petelin and Sergey Prokopyev, as well as NASA astronaut Frank Rubio, to the ISS in September.

There are currently seven people aboard the orbital outpost, but if MS-22 were deemed unfit, it would also mean the ISS has just one “lifeboat” capable of carrying four people, in case it needs to be evacuated.

Americans Josh Cassada and Nicole Mann, Japan’s Koichi Wakata and Russia’s Anna Kikina arrived on a SpaceX Crew Dragon in October.

The cause of the damage still remains unclear, said Montalbano. But it does not appear as though the Geminid meteor shower, an annual phenomenon, was to blame, since the hull was penetrated from a different direction.
