US Astronauts Complete 1st Of 5 Power Upgrade Spacewalks

Expedition 61 Flight Engineers Christina Koch and Andrew Morgan on Sunday.

Beginning the replacement of nickel-hydrogen batteries with newer, more powerful lithium-ion batteries on the far end of the station's port truss, Expedition 61 Flight Engineers Christina Koch and Andrew Morgan of NASA concluded their spacewalk at 2.40 pm EDT on Sunday, the United States space agency said.

In March, NASA announced plans to conduct its first ever all-women spacewalk with astronauts Christina Koch and Anne McClain.

On October 11, Mr Morgan and Ms Koch are scheduled to venture outside again for another spacewalk to continue the battery replacements on the first of the two power channels for the station's far port truss, NASA said.

After the batteries are replaced, the astronauts will perform another five fix missions. Koch served as the lead during Sunday's excursion with Morgan, her USA male crewmate. The second medium suit was put together on board in June.

"I'm sure that they'll sit back and reflect on it, as we all will". But things are looking up as Koch and McClain were both part of NASA's 2013 class which was half female.

Koch is also expected to make history for the longest single spaceflight by a woman with an astounding 328 days. "And that in the past, women haven't always been at the table". "And it's wonderful to be contributing to the human spaceflight program at a time when all contributions are being accepted, when everyone has a role, and that can lead, in turn, to increased chance for success".

Since the world's first spacewalk in 1965, only 14 women have walked in space, compared to 213 men, according to NASA.

Expect more women spacewalking together on the horizon.

During a press conference on Friday, Shireman said: "We don't do it for a specific crew, what we do is we look over the next two years, and look at all the crew members who are certified, and say, "Okay, what's the sweet spot?'" Shireman went on to say that over the next two years, a lot of 'medium suit people" will be heading to the ISS.

The latest spacewalk is the first of five outings that will take place this month, all of which can be watched live on NASA TV. According to NASA one lithium-ion battery will take the spot of every two nickel-hydrogen batteries now aboard the station.
