NASA International Space Station On-Orbit Status 20 June 2016

Expedition 48 officially began Saturday morning with Commander Jeff Williams and Flight Engineers Oleg Skripochka and Alexey Ovchinin continuing their stay aboard the International Space Station. They await the addition of three new crew members who will launch July 6 for a two-day ride to their new home in space.
Expedition 47 completed 186 days in space Saturday after landing in Kazakhstan. NASA astronaut Tim Kopra returned home to Houston the following day. European Space Agency astronaut Tim Peake flew to Cologne, Germany, to begin his reconditioning. Cosmonaut Yuri Malenchenko returned to Russia after completing his sixth mission to space.

Despite the weekend’s landing activities, science continues around the clock on the orbital laboratory. The crew is exploring how living in space affects the immune system and collected and stowed biological samples today for the Multi-Omics study. The crew is also setting up hardware for the NeuroMapping experiment. That study will research how spaceflight changes an astronaut’s brain and associated activities such as function, motor control, and multi-tasking abilities.

The next crew launch to the space station includes cosmonaut Anatoly Ivanishin, NASA astronaut Kate Rubins and Japanese astronaut Takuya Onishi. They will join Expedition 48 when their Soyuz MS-01 spacecraft docks to the Rassvet module July 8.

On-Orbit Status Report

Direct Current To Direct Current (DDCU) LA1A Trip: Last Thursday, DDCU LA1A tripped off due to a ~40 amp overcurrent. Parallel DDCU LA4A was already off for Battery 4A conditioning. A Failure Investigation Team (FIT) recommended the crew perform troubleshooting steps including rotation of the rack and visual inspection of the DDCUs, wire harnesses, and the Secondary Power Distribution Assembly (SPDA). The crew also performed multimeter measurements on both DDCU outputs on the face of the DDCU as well as on the output cable leading to downstream wiring for indications of a fault. Following the troubleshooting, another FIT was held and the recommendation was to R&R DDCU LA1A which the crew completed this morning. Both DDCUs and Pressurized Mating Adapter (PMA)2 shell heaters were powered on and are operating nominally. CEVIS has been reinstalled. Ground teams have recovered most affected loads with a few remaining items to be repowered tonight.

Multi-Omics Operations: The crew supported the Japan Aerospace Exploration Agency (JAXA) Multi-Omics investigation by collecting samples and inserting them in the Minus Eighty-degree Freezer for ISS (MELFI). The investigation evaluates the impacts of space environment and prebiotics on astronauts’ immune function by combining the data obtained from the measurements of changes in the microbiological composition, metabolites profiles, and the immune system.

NeuroMapping Operations: The crew set up the hardware and performed this experiment, including testing in both a “strapped in” and “free floating” body configuration. The investigation studies whether long-duration spaceflight causes changes to the brain, including brain structure and function, motor control, and multi-tasking abilities. It also measures how long it takes for the brain and body to recover from changes. Previous research and anecdotal evidence from astronauts suggests movement control and cognition can be affected in microgravity. The NeuroMapping investigation performs structural and functional magnetic resonance brain imaging (MRI and fMRI) to assess changes that occur after spending an extended period on the ISS.

Ammonia Measurement Kit Chip Measurement System (CMS) Battery Changeout: The CMS draws a small amount of current even while inactive, therefore the batteries must be changed periodically to ensure the CMS will activate in an emergency. During this procedure the crew verified that the CMS would have activated using the installed batteries near end-of-life, then replaced them.

Treadmill 2 (T2) Monthly Maintenance: The crew completed this regularly scheduled maintenance to inspect the bungee shackle key mount witness marks, Y-Axis isolators, two boot snubbers, and all four snubber arms for signs of free play.
