Wednesday’s spacewalk began at 7:13 a.m. ET.
Both of those astronauts are veteran spacewalkers. This is the eighth venture outside for both of those Cassidy and Behnken, according to NASA.
These spacewalks are the culmination of a sequence of electricity upgrades that began in January 2017 to change nickel-hydrogen batteries with new lithium ion batteries.
This spacewalk, equivalent to a person that took put past Friday, will emphasis on replacing batteries for one of the energy channels on the significantly starboard truss of the station. Mainly because the astronauts accomplished some of the jobs for this spacewalk past 7 days, they will also concentrate on tasks that were being scheduled for later spacewalks, route energy and ethernet cables, and operate other preparations for potential ability technique updates.
These cables will provide better views on upcoming spacewalks, in accordance to NASA.
These energy procedure upgrades, even so, are very little like changing batteries in your distant. The new batteries every have a mass of 428 kilos.
For this second spacewalk, Cassidy will be crew member I and sporting a spacesuit showing red stripes, when Behnken will serve as crew member II in a match with no stripes. Hurley and Russian cosmonaut Ivan Vagner will support Cassidy and Behnken into their spacesuits. Hurley will run the station’s robotic arm to aid the astronauts exterior the station.
The battery replacements, which will have a 20-yr life time, will set the station in a substantially superior configuration for the lengthy term, explained Kenneth Todd, deputy Intercontinental Room Station plan manager, during a NASA press convention previous week.
Behnken just lately talked about the spacewalk, and why it really is significant to swap the batteries, for the duration of a phone to the space station from CNN Innovation and Room Reporter Rachel Crane.
“When the place station is in the sunshine, it’s accumulating vitality and it requires to shop for when it really is in the dim,” he explained. “And so all those batteries, as they are cycled time and time yet again, they wear down and want to be changed. And so periodically that maintenance is demanded.”
Behnken mentioned he was looking forward to a further spacewalk experience.
“I really look ahead to the sights of the Earth when we get a no cost moment,” he mentioned. “I feel each and every astronaut, when they go out on their to start with spacewalk, they’re seriously targeted on trying to get all the things to do accomplished and do a good position so that they can most likely get a probability to do a further just one if the prospect provides by itself.
“But soon after you’ve performed a few and know what to count on as you go as a result of it, it is important to, you know, take some mental images, some psychological photos, or recall what it was like to be outside the house.”
