Expedition 50 crewmembers Shane Kimbrough (NASA) and Thomas Pesquet (France-ESA), ventured outside the ISS on Friday Jan 13, 2017 to start the second spacewalk in one week dedicated to the integration of new batteries.
The US EVA-39 spacewalk lasted 5 hours and 58 minutes and completed the installation of 3 adapter plates to connect 3 new Li-Ion batteries on the S4 IEA 1A Channel.
These new batteries were previously installed by Dextre days before. See previous post here.
Both astronauts exited the Quest Airlock, Kimbrough was EV1 (red stripes) and Pesquet was EV2 (no stripes).
Back at the IEA, the duo installed Adapter Plate F in slot 6 (yellow).
The old Ni-H2 battery from slot 4 is placed atop the just installed Adapter Plate F to remain in a passive state for the time being, available as a spare.
With slot 4 freed up, the astronauts installed Adapter Plate E achieving the minimum operational configuration for the 1A channel with Mission Control reporting good connectivity to both batteries.
Adapter Plate E is installed into slot 2 on the IEA. Mission Control confirmed that all 3 of the newly integrated batteries were showing nominal operation, giving the ISS its second Li-Ion driven power channel representing a quarter of the ISS power system.
All primary tasks were completed by 3 hours, leaving the crew 2 hours ahead of schedule. With plenty of time left, the team went on to do a series of Get-Ahead tasks.
- CLPA (Camera/Light Pan/Tilt Assembly) removal at the Mobile Transporter Relay Assembly
- “Rat’s Nest” engineering imaging
- Hand rails 0261 and 0262 removal at Destiny’s Lab
- Node 3 Axial shields
Ending the EVA, the pair moved back to the airlock.
In the upcoming days, the 3 old Ni-H2 batteries currently held by Dextre will be moved to the 3 empty slots on the HTV-6 EP.
On Jan 14, 2017, the 3 old Ni-H2 batteries held by DEXTRE were moved to the Exposed Pallet of the HTV-6.
