NASA astronauts Shane Kimbrough (left) and Peggy Whitson (proper) took an area stroll on March 24, 2017. Whitson broke the file for probably the most complete area stroll time for a feminine astronaut throughout the area stroll, Which was the eighth of his profession.

NASA astronaut Peggy Whitson (19459012) set a brand new area file for girls in area on Thursday (March 30) as she and her fellow NASA astronaut Shane Kimbrough ventured out of the Worldwide Area Station For the second time in seven days.
The pair got here out at 7:29 a.m. EDT (1129 GMT) and spent 7 hours and four minutes understanding of the laboratory in orbit. 4 hours and 23 minutes into the mission, Whitson broke the file for collected spacewalking time by a feminine astronaut. NASA astronaut Suni Williams held the earlier file for a complete of 50 hours and 40 minutes. Whitson, after finishing his eighth area stroll, broke that file, accumulating a complete of 53 hours and 22 minutes.
Right this moment's spacewalk accomplished a piece in progress to get the area station able to accommodate industrial spacecraft. This work started with the final area stroll, on March 24 throughout which Kimbrough disconnected the wires and electrical connections of the pressurized coupling adapter Three (PMA-Three), which was relocated with the robotic arm of the area station two days later . Regardless of a profitable mission, the area stroll was not all triumph: the astronauts by chance misplaced some gear within the area vacuum.
With the PMA-Three put in within the Concord module, Whitson completed putting in it by reconnecting these cables. It additionally eliminated and saved the PMA-Three thermal jacket to make room for the brand new Worldwide Coupling Adapter that’s scheduled to reach in 2018. Little did she know or management the mission, however that protecting cowl can be helpful later, when Issues don’t fairly go in accordance with plan.
Gear misplaced in area
After Kimbrough completed putting in a brand new exterior laptop, he and Whitson discovered themselves within the gate to retrieve two pairs of axial shields, which led to Node Three, or the Tranquility module, the place PMA-Three was beforehand discovered. Elimination of PMA-Three left the docking port at Node Three uncovered, and these shields present safety in opposition to micrometeorites. Earlier than the area walkers might tie the shields, one by chance escaped and moved out of attain.
"Peggy, I wouldn’t have a defend," Kimbrough stated with a groan. Whitson seemed round and positioned the piece of kit. "Ah … it's proper subsequent to the radiator," he stated. "It’s transferring zenith station [space-ward] maybe half a foot a second." It was later requested whether or not a mix between the grounding strap and a strap of comparable look on the defend might have led to the escape of the defend.
Fortuitously, floor management groups at NASA's Johnson Area Heart in Houston got here up with an on-site answer. They requested area walkers to retrieve the deck that Whitson had faraway from the PMA-Three and wrapped it over the uncovered a part of Node Three. The EVA (Extravehicular Exercise, or Spacewalk) Job Staff eliminated some replicas of the gear to Board and found the precise dimensions and had been capable of emerge in actual time whereas the EVA was going by means of, all these procedures to cowl that uncovered level, "stated NASA commentator Gary Jordan. The axial measurements are roughly 1.6 m (5 ft) lengthy, 2 ft (zero.6 m) extensive and a couple of.6 inches (6.6 cm) thick
Now the material defend is orbiting the Earth forward of the area station and poses no risk, Jordan stated. The improvised cowl will work for now, since it’s fabricated from the identical materials because the misplaced defend and has tailored to the port with bandages. Whether or not the defend will have to be changed by future missions stays to be decided "[The] the crew will consider how everlasting the PMA-Three protection answer will probably be and consider a plan ahead, NASA spokesman Dan Huot advised Area. Com in an e mail, including that it's "too early to make the decision."
Regardless of the setback, these two skilled spacewalkers went by means of all their assigned duties and even had time for a "get forward" activity, by which they took some images to look at the widespread docking mechanism on Node 2, or the Concord module , The place PMA-Three now resides. These images will assist NASA assess what future work ought to be executed earlier than industrial spacecraft can dock there.
