NASA Space Station On-Orbit Status 11 October 2019 - Spacewalks Completed

Expedition 61 Flight Engineers Christina Koch and Andrew Morgan of NASA concluded their spacewalk at the International Space Station at 2:23 p.m. EDT.

During six-hour and 45-minute spacewalk, the two NASA astronauts continued the replacement of nickel-hydrogen batteries with newer, more powerful lithium-ion batteries on the far end of the station's port truss.

Astronauts also were able to accomplish several get-ahead tasks setting up for the next spacewalk.

These new batteries provide an improved power capacity for operations with a lighter mass and a smaller volume than the nickel-hydrogen batteries. On Oct. 16, Morgan and NASA astronaut Jessica Meir are scheduled to venture outside for another spacewalk to continue the battery replacements on the first of the two power channels for the station's far port truss. The following spacewalks dedicated to the battery upgrades are scheduled on Oct. 21 and 25.

After completion of the battery spacewalks, the second half of this sequence of spacewalks will focus on repairs to the space station's Alpha Magnetic Spectrometer. Dates for those spacewalks still are being discussed, but they are expected to begin in November.

Space station crew members have conducted 220 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 57 days 13 hours and 12 minutes working outside the station.

On-Orbit Status Report

P6 Battery Extravehicular Activity (EVA) #2 (US EVA #57): Today, the ISS crew completed EVA #2 with the crew lock egress occurring around 6:38 am CT. Today's EVA focused on completing the P6 Solar Array Channel 2B Li-Ion battery upgrades. This included installing the third and final Li-Ion battery to the Channel 2B IEA. The official EVA duration was 6 hours and 45 min. Tasks accomplished are as follows:

Primary tasks:
NiH2 Battery 4 from the Integrated Equipment Assembly (IEA) to the External Pallet (EP) Slot B.
Adapter Plate (AP) B from the EP to Slot 4 on the IEA
NiH2 Battery 6 from the IEA to AP-B Slot 4 on the IEA
Li-Ion Battery D from the EP to Slot 6 on the IEA.
NiH2 Battery 5 from the IEA to EP D.
AP-D from the EP to Slot 5 on the IEA.
Site 4B Worksite Prep
Get ahead tasks completed:
4B NiH2 battery #5 H1 bolt torque release to support Robotics installation of spare Li-Ion battery.
Disconnect of Ethernet Cables from EXT-EPIC MDMs.
