Pair of spacewalkers of NASA substituted out important photo voltaic display screen electric batteries on Thursday, July 16, at the International Spaceport station, virtually completing the comprehensive exchanging job needed to preserve the orbiting research laboratory powered throughout 2024.
Bob Behnken and also Chris Cassidy, NASA rocketeers, zoomed by means of their work, eliminating 6 aged nickel-hydrogen electric batteries on the far-flung panel S6 bind of the International Space Station (ISS). The 2 rocketeers likewise launched 3 lithium-ion electric battery replacements and also installed a brand new higher megapixel cam on the external edge of the ISS.
The rocketeers completed the 6-hour spacewalk at around 1:10 p.m. EDT (1710 GMT), roughly 30 moments just before deliberate. Near completion of the spacewalk, Behnken and also Cassidy kept in mind some potential attribute along with the pins holding the Quest airlock hatch securely; the 2 took images for the procedure management to review eventually along with one more NASA spacewalk booked for July 21.
Cassidy and also Behnken, each on their 9th procedure, were actually originally needed to do away with 5 nickel-hydrogen electric batteries found on the S6 truss. After 4.5 hrs outside the International Space Station, being actually a hr ahead of time of opportunity and also possessed the possibility to carry out a bit even more job.
They were actually contacting the 2 rocketeers coming from Johnson Space Center of NASA situated in Houston, Josh Kutryk, that a rocketeer coming from the Canadian Space Agency passed on excellent updates coming from the groups on the ground. Kutryk, having actually been actually entrusted to help the spacewalks in the course of their procedure, validated that there is actually an approach converging to consider carrying out the final electric battery.
After some moments, the rocketeers entered, quickly eliminating the electric battery. The spacewalks began to poke fun concerning the ease of their activities, specifying that there needs to be actually one more eradication because it never ever finishes, virtually breaking along with giggling. Kutryk allowed the staff carry on talking momentarily at that point joined all of them, specifying that they diligently discuss their positive outlook.
It seemed that the most significant trouble encountered due to the spacewalkers was actually managing the very hot sunshine while eliminating the very first brand new lithium-ion electric battery coming from an exterior pallet taken through Canadarm2, which is actually an electronic upper arm administered through Doug Hurley, a NASA rocketeer coming from inside the International Space Station.
Cassidy accomplished the unbolting and also meticulously eliminated his footwear coming from a portable shoe restriction maintaining him in location. While drifting, Cassidy included that depending on to him, there was actually an EVA survey some years back talking to whether they required the tough spacesuit hat, and also the solution was actually of course.
