The Expedition 50 crew is gearing up for three spacewalks over two weeks to continue the external maintenance at the International Space Station. Also, the SpaceX Dragon is returning to port today after completing a month-long stay at the station.

Astronauts Shane Kimbrough and Thomas Pesquet will begin the first spacewalk Friday at 8 a.m. EDT. NASA TV will begin live coverage of the 198th spacewalk in support of station assembly and maintenance Friday at 6:30 a.m.

The two spacewalkers will spend 6.5 hours disconnecting cables from the Pressurized Mating Adapter-3 (PMA-3), lubricating the tip of the Canadarm2, inspecting a radiator and replacing cameras. Computer relay boxes will also be replaced. The new hardware contains software upgrades for future dockings of commercial crew vehicles.

Friday’s cable work on the PMA-3 will prepare it for its relocation from the Tranquility module to the Harmony module on March 30. The relocation opens up the Tranquility port for the future installation of the new International Docking Adapter-3 set to be delivered on a future cargo mission.

The SpaceX Dragon is heading to its port today in southern California after a successful splashdown in the Pacific Ocean Sunday morning. NASA support personnel will retrieve the numerous research samples stowed in Dragon’s cargo hold and deliver them to scientists for analysis. The results of the advanced space science may improve disease therapies and injury treatments on Earth.

NEW SCIENCE RESEARCH AND ISS MAINTENANCE

Astronauts Thomas Pesquet and Peggy Whitson set up the Microgravity Science Glovebox inside the Destiny lab module while space station maintenance tasks continue.

With all four spacecraft safely docked with the International Space Station, very interesting, new science research is underway. Ongoing maintenance tasks are a daily activity; however, during this time, existing space suits are being cleaned and battery elements are getting charged for use or emergency. Earth return practice also continues in case of any unforeseen situation. For now, all is running, as planned aboard ISS. Please read below, inclusive of web links regarding experimentation:

Astronaut Thomas Pesquet of the European Space Agency cleaned U.S. spacesuit cooling loops and collected water samples for a periodic maintenance check today. Afterward, he began charging spacewalking gear including helmet lights and tool batteries.

Commander Shane Kimbrough and NASA astronaut Peggy Whitson worked on life support maintenance today. They removed and disassembled valves and ducts to access old carbon dioxide filters that needed replacing inside the Destiny lab module. The duo will be back at work Wednesday installing newer generation filters.

One of the main objectives of the International Space Station is to provide an orbital laboratory to research how living in space long-term affects humans. New and ongoing experiments conducted today may provide benefits for humans on and off Earth.

Kimbrough checked on rodents being observed for a tissue regeneration study. Whitson continued researching stem cells with a new microscope delivered last week aboard the SpaceX Dragon. Cosmonaut Andrey Borisenko studied how viruses behave in space while his fellow cosmonauts, Sergey Ryzhikov and Oleg Novitskiy, explored non-invasive ways to monitor a crew member’s health and methods to keep their skills sharp on and off Earth.
