NASA and Russia weigh choices for astronaut return after spacecraft leak – Egypt Independent


Officials at NASA and Russia’s house company, Roscosmos, are working to determine learn how to convey house a number of individuals on the International Space Station after a Russian Soyuz spacecraft sprang a leak final week.

None of the seven individuals presently on board the ISS — together with three Roscosmos cosmonauts, three NASA astronauts and one astronaut with Japan’s house company — have been ever in any hazard on account of the leak, officers have noted. But it’s not but clear whether or not the spacecraft will be capable to make a visit again house with its crew on board.

The Soyuz MS-22 spacecraft ferried NASA’s Frank Rubio and two Russian cosmonauts, Sergey Prokopyev and Dmitry Petelin, to the house station on September 21. It was scheduled to convey them again to Earth in March. But Roscosmos is now evaluating whether or not to fly its subsequent Soyuz mission to the ISS empty and transfer the launch up two to a few weeks in order that the spacecraft can function a rescue car for Rubio, Prokopyev, and Petelin if Soyuz MS-22 is deemed not secure sufficient for the crew. If Roscosmos goes with that plan, the following Soyuz mission may carry off in February, in keeping with Montalbano.

The leak on the Soyuz MS-22, which is presently connected to the ISS at one of many orbiting laboratory’s eight docking ports, was recognized on December 14. It forced the delay of a deliberate spacewalk by two cosmonauts final week, and stay photographs throughout a NASA broadcast confirmed liquid spewing out from the spacecraft.

Roscosmos decided that the leak occurred on an exterior cooling loop of the Soyuz. The leak just isn’t anticipated to trigger any exterior corrosion or harm to the outside of the ISS, Montalbano famous, saying the leaked coolant “boils up very quickly” because it’s uncovered.

It’s not but clear was brought about the leak, which has been traced to a small gap that might have been brought on by a collision with a chunk of house particles, a mechanical downside or another subject, in keeping with Montalbano.

Space particles was, nevertheless, the sure explanation for a one-day delay for a spacewalk planned by the United States. Two astronauts have been slated to enterprise out on Wednesday to put in a brand new photo voltaic array to the house station’s exterior, however the ISS needed to maneuver out of the best way of a chunk of spaceborne rubbish. The particles was decided to be a chunk of an outdated Russian rocket.

The ISS was capable of maneuver efficiently, and the US spacewalk kicked off Thursday morning with out subject.
