For the primary time, astronauts are being evacuated from the Worldwide Area Station (ISS) for medical causes. The precise nature of the “medical scenario” has not been recognized for privateness causes, nor has the astronaut it has affected. However 4 of the seven crew members on board the ISS are coming house early.
The astronauts returning to Earth are the members of the Crew-11 mission, which launched on 1 August and was initially deliberate to return in late February. In an 8 January press convention, NASA administrator Jared Isaacman mentioned that the choice to return the astronauts early was made partially as a result of the mission goals are almost all full, so ending the mission early just isn’t as massive of a deal.
“As a result of the astronaut is completely secure, this isn’t an emergent evacuation,” mentioned NASA’s chief well being and medical officer, James Polk, in the course of the press convention. “We’re not instantly disembarking and getting the astronaut down.” Emergency medical evacuations may very well be carried out in a matter of hours, Isaacman mentioned, however on this case the crew will likely be evacuated within the subsequent few days.
There have been medical incidents aboard the ISS earlier than, however till now all of them have been minor sufficient that they may very well be handled in orbit. “We now have a really strong suite of medical {hardware} on board the Worldwide Area Station, however we don’t have the whole quantity of {hardware} that I’d have within the emergency division, for instance, to finish a workup of the affected person,” mentioned Polk. “The medical incident was enough sufficient that we have been involved sufficient concerning the astronaut [and] we want to full that workup, and one of the best ways to finish that workup is on the bottom.”
The 4 members of Crew-11 – two NASA astronauts, one Russian cosmonaut and one Japanese astronaut – will trip house aboard the identical Dragon spacecraft that shuttled them to the ISS, regardless of solely one among them being ailing or injured. A number of medical amenities on Earth will likely be ready forward of time to absorb the affected crew member for assessments and therapy. Whereas this case is unprecedented, the precise evacuation operation just isn’t considerably completely different from how crews often return to Earth on the finish of their missions, Isaacman mentioned.
“Within the 25 years of the historical past of the Worldwide Area Station we’ve had many fashions… which have mentioned that we must always’ve had a medical evacuation roughly each three years… and we’ve not had one up to now,” says Polk.
The evacuation will depart only one NASA astronaut and two Russian cosmonauts aboard the ISS till the arrival of the Crew-12 mission, which was initially slated to launch round 15 February however could also be moved up after this incident.
