NASA International Space Station On-Orbit Status 2 September 2016.

Two astronauts are cleaning up after a spacewalk while a pair of cosmonauts are getting a Soyuz spacecraft ready for departure after the Labor Day weekend. On the ground, three new crew members are preparing for a launch to the International Space Station at the end of the month.

Commander Jeff Williams and Flight Engineer Kate Rubins completed a spacewalk Thursday, retracting a thermal radiator and installing a pair of high definition cameras. Today, the astronauts are recharging spacesuits and tidying up the Quest airlock by stowing their tools and other spacewalk gear.

The Expedition 48 crew now turns its attention to a change of command on Monday, followed by three crew members returning to Earth on Tuesday. Williams will hand over station control to cosmonaut Anatoly Ivanishin before going home the following day with Flight Engineers Oleg Skripochka and Alexey Ovchinin.

The trio will undock Tuesday at 5:51 p.m. EDT inside the Soyuz TMA-20M spacecraft officially ending the Expedition 48 mission. After a few hours they will parachute to a landing in Kazakhstan after 5-1/2 months in space.

Back on Earth, new station crew members Shane Kimbrough, Sergey Ryzhikov and Andrey Borisenko participated in traditional ceremonies and final qualification exams. They will join the Expedition 49 crew two days after their Sept. 23 launch inside the Soyuz MS-02 spacecraft.

On-Orbit Status Report

Trailing Thermal Control Radiator (TTCR) Extravehicular Activity (EVA) Post-EVA Activities: Today, the USOS crew had a half-duty day. They completed their post-EVA medical checkups, and performed an Extravehicular Mobility Unit (EMU) Water Recharge procedure on EMUs 3003 and 3008. The EMUs and associated equipment were then be prepared for storage. They then participated in an EVA debrief to discuss any comments regarding preparation and execution of the EVA.

Skin-B Operations: The Skin-B investigation was conducted as FE-6 performed Corneometer, Tewameter and Visioscan measurements on his forearm. The Corneometer measures the hydration level of the stratus coreum (outer layer of the skin), the Tewameter measures the skin barrier function, and the Visioscan measures the skin surface topography. Skin B is a European Space Agency (ESA) investigation that aims to improve the understanding of skin aging, which is greatly accelerated in space. The data will also be used to verify the results from previous testing for the SkinCare investigation on the ISS.

Space Headaches: The crew completed the ESA Space Headaches questionnaire which provides information that may help in the development of methods to alleviate associated symptoms and improvement in the well-being and performance of crew members in space. Headaches during space flight can negatively affect mental and physical capacities of crew members which can influence performance during a space mission.

Habitability Walk-through: The crew recorded a walk-through video documenting observations of life onboard ISS, providing insight related to human factors and habitability. The Habitability investigation collects observations about the relationship between crew members and their environment on the ISS. Observations can help spacecraft designers understand how much habitable volume is required, and whether a mission's duration impacts how much space crew members need.
