NASA Postpones ISS Spacewalk Over Medical Subject, Considers Early Crew Return

A medical problem affecting a Crew-11 astronaut aboard the Worldwide House Station (ISS) has pressured the company to postpone Thursday’s spacewalk indefinitely and think about bringing the crew residence early.

In a press release issued Wednesday, NASA mentioned the company is monitoring a well being concern affecting a member of Crew-11 that arose Wednesday afternoon aboard the orbital laboratory. An emailed replace to Space.com obtained early Thursday morning said that NASA is “actively evaluating all choices, together with the potential of an earlier finish to Crew-11’s mission.” The company has not disclosed what the well being problem is nor which crew member is affected out of respect for his or her medical privateness.

“These are the conditions NASA and our companions practice for and put together to execute safely,” the assertion to House.com reportedly reads. “We’ll present additional updates throughout the subsequent 24 hours.”

Crew-11, which consists of area station commander Mike Fincke (58), flight engineer Zena Cardman (38), Japanese astronaut Kimiya Yui (55), and Russian cosmonaut Oleg Platonov (39), launched to the ISS aboard a SpaceX Crew Dragon capsule on August 1. The 4 astronauts are within the ultimate weeks of their mission, scheduled to return to Earth in mid-February. As of now, that’s nonetheless the official plan.

NASA’s emergency contingency plan

NASA has by no means returned an astronaut from the ISS early resulting from a medical problem, however the company is all the time ready for the unlikely occasion it wants to take action. On this case, bringing Crew-11 residence early could be comparatively simple, as their Crew Dragon spacecraft continues to be docked to the ISS.

All 4 of the crew members would board the Dragon capsule and certain head for reentry and splashdown within the Pacific Ocean, as they might have in February. A SpaceX restoration vessel primarily based in Southern California would then retrieve the spacecraft and crew.

Crew-11’s early departure wouldn’t go away the ISS uncrewed. NASA astronaut Chris Williams and two Russian cosmonauts—Sergey Kud-Sverchkov and Sergey Mikayev—who launched to the area station in November aboard a Russian Soyuz spacecraft would stay on the area station.

Uncommon medical spacewalk delay

It’s uncommon for NASA to postpone a spacewalk resulting from a medical problem, however they’ve beforehand been pushed again resulting from minor considerations, comparable to a pinched nerve or spacesuit discomfort.

NASA’s Fincke and Cardman have been presupposed to emerge from the area station’s Quest airlock at roughly 8 a.m. ET on Thursday. It could have been Cadman’s first spacewalk and Fincke’s tenth, tying him with Peggy Whitson for probably the most spacewalks by a NASA astronaut.

Their main process was to organize the 2A energy channel for future set up of a roll-out photo voltaic array. This array will present extra energy to help the previous few years of operation and, finally, the lab’s deorbit. Cardman and Fincke would have additionally put in jumper cables, photographed station {hardware}, and swabbed the outside of the ISS to gather potential microorganism samples, in response to NASA.

One other spacewalk is scheduled for 7:20 a.m. ET on Thursday, January 15, sending one other pair of NASA astronauts exterior the area station to exchange a high-definition digicam, set up a brand new docking support for visiting spacecraft, and relocate a number of cooling hoses. The names of the taking part astronauts have been presupposed to be introduced after the January 8 spacewalk. It’s at present unclear whether or not this medical problem will power NASA to postpone the January 15 EVA.
