A mission was announced Wednesday to rescue three crew members of the International Space Station (ISS) after the vessel they rode into orbit in September sustained a leak.

Russian space agency Roscosmosplans to launchthe spacecraftSoyuz MS-23on Feb. 20 so that cosmonauts Sergey Prokopyev and Dmitri Petelin as well as NASA astronaut Francisco Rubio will have a ride back home to earth, CNN and Reuters reported.

Meanwhile, MS-22, the damaged spacecraft that brought the crew to the ISS, will return to earth without any passengers about a week or two upon the arrival of MS-23, according to CNN.

NASA and Roscosmos are currently evaluating if they will need to mount a rescue mission to the ISS.

According to Joel Montalbano, ISS program manager at NASA’s Johnson Space Center in Houston, MS-22 is deemed unfit to serve as a transportation vehicle for the crew due to the leak whichcould raise the temperature in the cabin to 100 degreesor more along with high humidity,The New York Timesreported.

“They are ready to go with whatever decisionwe give them,” Montalbano, said in a news conference on Wednesday, per Reuters. “I may have to fly some more ice cream to reward them.”

However, in the event of an emergency, while waiting for MS-23 to arrive, MS-22 would be considered to be used as a rescue vessel.

“When the crew will have a real threat to life on the station, then probably the danger of staying on the station can be higher than going down in an unhealthy Soyuz,” Sergei Krikalev, Russia’s chief of crewed space programs, explained.

Krilavev said the agency and the crew were aware of the danger and possibility of such damages occurring in space.

“Space is not a safe place, and not a safe environment. We have meteorites, we have a vacuum and we have a high temperature and we have complicated hardware that can fail,” Krikalev added. “Now we are facing one of the scenarios … we are prepared for this situation.”
