SAN DIEGO (CNS) - UC San Diego alumna and astronaut Jessica Meir and fellow astronaut Christina Koch reflected today on their participation in the first all-female space walk in history.Meir and Koch ventured outside the International Space Station on Friday morning to replace a faulty battery charge/discharge unit that failed to activate after new lithium-ion batteries were installed on the space station's exterior structure Oct. 11, according to NASA.During a news conference from the International Space Station, Meir and Koch said participating in the space walk was difficult to put into words."I will never forget that moment coming out of the hatch and looking down and seeing just my boots and the Earth below and it was such a spectacular and beautiful sight," Meir said.
