iss050e014812 (Dec. 14, 2016) ---A U.S. spacesuits is seen attached to the wall inside the Quest Airlock aboard the International Space Station. The Expedition 50 crew performed routine maintenance on the suits throughout December to prepare for upcoming spacewalks in January 2017 that will see the astronauts work in tandem with external robotics to install six new lithium-ion batteries on the station.

ISS Daily Summary Report – 12/23/2016


Extravehicular Mobility Unit (EMU) Maintenance: The crew completed the following in preparation for upcoming EVA’s:

•EMU 3006 Loop Scrub
•EMU 3008 Loop Scrub – was cancelled due to a water leak at the Service and Cooling Umbilical (SCU).  Time will be scheduled next week to changeout the SCU and complete the EMU 3008 loop scrub.
•Liquid Cooling Ventilation Garments (LVCGs) filled with water
•Conductivity tests

ISS Daily Summary Report – 12/27/2016


Extravehicular Mobility Unit (EMU) 3008 Loop Scrub:

Last Friday the crew attempted to perform the EMU 3008 loop scrub which could not be completed due to a leak at the Service and Cooling Umbilical (SCU) Display and Control Module (DCM) interface.  Earlier today the crew removed the SCU however during the installation of the new SCU they encountered resistance while mating the SCU connection.  The SCU did not receive power upon activation. The crew reported finding damage to the connecter during an inspection of the connectors.  Based on ground specialist recommendations the crew used pliers to unbend the SCU connector back shell prior to them remating the SCU to the UIA.  The new SCU has been reinstalled and it powered up nominally.  The crew will complete the checkout of the new SCU and EMU 3008 Loop Scrub later this week.

MEDIA ADVISORY M16-146

NASA Preps for Space Station Power Upgrade Spacewalks; Live NASA TV Coverage


Expedition 50 astronauts will venture outside the International Space Station at 7 a.m. EST Jan. 6 and 13 to perform a complex upgrade to the orbital outpost’s power system. Coverage of the spacewalks will begin at 5:30 a.m. on NASA Television and the agency’s website.

On Wednesday, Jan. 4, NASA TV will air a briefing at 2 p.m. from the agency’s Johnson Space Center in Houston to preview the spacewalk activities. The briefing participants are:

    Kenneth Todd, International Space Station Operations Integration Manager
    Jud Frieling, flight director for Jan. 6 spacewalk
    Gary Horlacher, flight director for Jan. 13 spacewalk
    Troy McCracken, lead battery replacement robotics officer
    Kieth Johnson, lead spacewalk officer

Media may attend the briefing at Johnson or ask questions by calling the Johnson newsroom at 281-483-5111 no later than 1:45 p.m. Jan. 4.

Working on the right side truss of the space station, the crew members will install adapter plates and hook up electrical connections for six new lithium-ion batteries that were delivered to the station in December.

Expedition 50 Commander Shane Kimbrough and Flight Engineer Peggy Whitson of NASA will perform the first spacewalk Jan. 6. The work will continue Jan. 13 during the second spacewalk, which will be conducted by Kimbrough and Flight Engineer Thomas Pesquet of ESA (European Space Agency).

Prior to each spacewalk, the new batteries will be robotically extracted from a pallet to replace 12 older nickel-hydrogen batteries through a series of robotic operations. Nine of the older batteries will be stowed in a cargo resupply craft for later disposal, while three will remain on the station’s truss, disconnected from the power grid. The robotic operations will not air on NASA TV.

This will be the 196th and 197th spacewalks in support of space station assembly and maintenance. Kimbrough will be designated extravehicular crew member 1 (EV 1), wearing the suit bearing red stripes for both spacewalks, the third and fourth of his career.

Whitson will be making the seventh spacewalk of her career and match the record of NASA’s Suni Williams, for most spacewalks by a woman. She will be designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes for the first spacewalk.

Pesquet, who will be making the first spacewalk of his career, will be extravehicular crew member 2 for the second spacewalk, also wearing a suit with no stripes.

Extravehicular Mobility Unit (EMU) 3008 Loop Scrub:

Last Friday the crew began EMU 3008 loop scrub which could not be completed due to a leak at the Service and Cooling Umbilical (SCU) Display and Control Module (DCM) interface.  Following yesterday’s installation of a new SCU, this morning the crew completed the activation and checkout of the new equipment followed by a nominal EMU 3008 loop scrub.

The SSRMS (with DEXTRE?) is moving towards batteries.  If I remember correctly this is to loosen the bolts holding the batteries in place before the spacewalk...

It looks like there is a battery (pack?) on the SSRMS/DEXTRE
