Spacer EVA-56 BY KRZYSZTOF KANAWKA ON 7 PAŹDZIERNIKA 2019
(...) Zadaniem spaceru EVA-56 była wymiana jednego z zestawu akumulatorów. Jest to ważny element zasilania Międzynarodowej Stacji Kosmicznej (ISS), który wymaga wymiany. Poprzednia generacja akumulatorów niklowo-wodorowych wymaga wymiany na nową generację akumulatorów litowo-jonowych. Prace wymagały wyjścia astronautów aż na sam “koniec” Stacji, aż do zestawu paneli słonecznych. Spacer EVA-56 przebiegł sprawnie – pod koniec astronauci wykonali kilka dodatkowych zadań. (...)
Spacer EVA-57 jest obecnie planowany na 11 października. Wówczas w przestrzeń kosmiczną wyjdą również Christina Koch i Andrew Morgan. (...)

On Sunday’s spacewalk, the astronauts removed one of the old nickel-hydrogen batteries and transferred it to the HTV cargo pallet mounted on the station truss. Then they retrieved a new lithium-ion battery and installed it on the P6 truss’s integrated equipment assembly, followed by the removal of another nickel-hydrogen battery for mounting on the HTV pallet, which will eventually re-enter the atmosphere and burn up.
“The choreography that the crew members have back and forth is very important because they’re going to be moving a box that’s about 428 pounds (194 kilograms), and taking it off of the pallet and moving it out to the integrated equipment assembly (on the P6 truss),” Johnson said in a press briefing before Sunday’s spacewalk. “And then they’ll take off an old battery, which weighs about 365 pounds (165 kilograms), and bring that back again.”
The battery boxes have no weight in microgravity, but they are still massive and bulky. (...)
