Two NASA astronauts finished upgrades to the International Space Station's power grid, marking the second all-female spacewalk, Wednesday, January 15.
Meir was joined by fellow astronaut Christina Koch on the walk, which was necessary to replace batteries on solar panels on the outside of the station. Last October, they teamed up for the world's first spacewalk by two women.
Meir earned a doctorate in marine biology from Scripps Institution of Oceanography at UCSD in 2009, according to her NASA bio. Eastern Time for the first spacewalk of 2020 and ended at 2:04 p.m. ET.

The problem put the mission, which is expected to last six and a half hours, around 30 minutes behind schedule.
NASA is in the process of replacing all 48 of the space station's older-generation nickel-hydrogen batteries with 24 more powerful lithium-ion units, along with circuit-completing "adapter plates" to fill in for batteries that were removed but not replaced. They are scheduled to conduct another spacewalk on Monday to finish the battery replacement.
The new batteries are arranged in sets of six in integrated electronics assemblies, or IEAs, at the bases of the station's four main solar array wings.
Recently, Koch marked 300 days in space. The astronauts would possibly no longer salvage it reattached so that they took it off and continued with the spacewalk.More news: Conor McGregor Eyeing Boxing World Championship, Wants Mayweather Rematch
Koch and Meir are included in the list of 12 women who could be the first female astronaut on the moon in 2024.
