Wednesday’s spacewalk started at 7:13 a.m. ET and concluded at 1:14 p.m. ET. It final for six hrs and 1 moment.
Equally astronauts are veteran spacewalkers. This was the eighth undertaking exterior for the two Cassidy and Behnken, in accordance to NASA.
These spacewalks are the end result of a series of power updates that began in January 2017 to substitute nickel-hydrogen batteries with new lithium ion batteries.
This spacewalk, very similar to a single that took place previous Friday, was targeted on changing batteries for one of the electrical power channels on the considerably starboard truss of the station. Due to the fact the astronauts achieved some of the responsibilities for this spacewalk very last week, they also worked on jobs scheduled for later spacewalks, routed electrical power and ethernet cables, and laid the groundwork for foreseeable future power method updates.
These cables will deliver superior sights on future spacewalks, in accordance to NASA.
These electric power program upgrades, nonetheless, are nothing like changing batteries in your distant. The new batteries every have a mass of 428 pounds.
For this spacewalk, Cassidy was crew member I and wore a spacesuit demonstrating crimson stripes, although Behnken served as crew member II in a suit with no stripes. Hurley and Russian cosmonaut Ivan Vagner helped Cassidy and Behnken into their spacesuits. Hurley operated the station’s robotic arm to guidance the astronauts outdoors the station.
The battery replacements, which will have a 20-year life span, will put the station in a substantially better configuration for the extended time period, reported Kenneth Todd, deputy Worldwide Room Station method supervisor, for the duration of a NASA push convention past week.
Behnken just lately discussed the spacewalk, and why it is really important to replace the batteries, for the duration of a call to the space station from CNN Innovation and Area Reporter Rachel Crane.
“When the place station is in the sunlight, it can be collecting electricity and it requires to retail store for when it really is in the dim,” he said. “And so these batteries, as they are cycled time and time again, they put on down and need to be changed. And so periodically that upkeep is necessary.”
Behnken mentioned he was searching ahead to an additional spacewalk working experience.
“I actually look forward to the sights of the Earth when we get a absolutely free minute,” he explained. “I feel every astronaut, when they go out on their to start with spacewalk, they are genuinely focused on making an attempt to get all the routines completed and do a superior occupation so that they can almost certainly get a possibility to do yet another a person if the option offers by itself.
“But right after you’ve got performed a pair and know what to hope as you go by it, it is critical to, you know, get some psychological photos, some psychological visuals, or recall what it was like to be exterior.”
