We’re saddened by the loss of legendary @roscosmos cosmonaut Alexei Leonov who became the first human to walk in space on March 18, 1965. His venture into the vacuum of space began the history of extravehicular activity that makes today’s @Space_Station maintenance possible. https://t.co/8EavxJd5R1

LIVE NOW: #Spacewalktober continues! At 7:38am ET, @AstroDrewMorgan and @Astro_Christina set their spacesuits to battery power, marking the beginning of a 6.5 hour spacewalk to install new lithium-ion batteries. Watch: https://t.co/LxP4EwLQS3

LIVE NOW: Coverage begins from our Mission Control Center as @AstroDrewMorgan & @Astro_Christina prepare for a spacewalk. They will exit the @Space_Station at 7:50am ET to install powerful lithium-ion batteries. Tune in:  https://t.co/LxP4EwLQS3

Some astronauts have referred to a spacewalk as a “fingertip ballet." Tune in live tomorrow at 6:30am ET to watch @AstroDrewMorgan and @Astro_Christina prepare to venture outside of the @Space_Station to complete one of these microgravity dances.
