HOUSTON (NASA PR) — Expedition 59 Flight Engineers Nick Hague and Anne McClain of NASA concluded their spacewalk at 2:40 p.m. EDT. During the six-hour, 39-minute spacewalk, the two NASA astronauts successfully replaced nickel-hydrogen batteries with newer, more powerful lithium-ion batteries for the power channel on one pair of the station’s solar arrays.
NASA has replaced an astronaut set to launch to the International Space Station (ISS) in June with a backup.
Jeanette Epps, who was set to become the first African American crew member on the space station, has been reassigned to the Astronaut Office at NASA’s Johnson Space Center, the space agency announced. She will be considered for future flights.
“Serena Auñón-Chancellor, who previously was assigned to Expedition 58/59, has been reassigned to the Expedition 56/57 crew, launching in June,” NASA said in a press release. ” Anne McClain, a member of the 2013 astronaut class, will fly on the Expedition 58/59 crew, launching in November.”
NASA did not give provide a reason for the reassignment of Epps, who was selected as an astronaut in 2009.
