POSTPONED

5th OF FIVE SPACEWALKS TO REPLACE ISS BATTERIES, date TBD, Earth orbit

UPDATED October 15 — this spacewalk has been postponed.  A new has not been announced.

Astronauts aboard the International Space Station (ISS) will conduct a series of five spacewalks to replace some of the original nickel-hydrogen batteries on the exterior of the space station with new lithium-ion batteries that were just delivered by Japan’s HTV-8 cargo spacecraft.  Astronauts have already replaced some of the batteries and a final round will take place next spring after the next HTV delivery.

The five spacewalks will be conducted on the following dates, with crew assignments as of October 4, 2019.  During an October 4 press briefing, NASA ISS Program Manager Kirk Shireman and astronaut Megan McArthur, Deputy Chief of the Astronaut Office, stressed that they be learning as they go along so changes are possible.

The four U.S. Operating Segment (USOS) astronauts are NASA’s Christina Koch, Drew Morgan and Jessica Meir and the European Space Agency’s Luca Parmitano.

NASA TV will cover all of the spacewalks, each of which will last about 6.5 hours.

Fifty-five USOS spacewalks — or extravehicular activities (EVAs) — have already taken place.  These are numbers 56-60.

EVA 56:  October 6, Koch and Morgan
EVA 57:  October 11, Koch and Morgan

EVA 58:  October 16, Morgan and Meir

EVA 58 was revised and will now involved Koch and Meir and will be the 1st female spacewalk (instead of EVA 59).  The date is Oct 17 or 18.

EVA 59:  October 21, Koch and Meir (crew assignments could change)
EVA 60:  October 25, Meir and Parmitano (crew assignments could change)
