Expedition 50 Commander Shane Kimbrough of NASA and Flight Engineer Thomas Pesquet of ESA (European Space Agency) are going to conduct an extravehicular activity EVA to prepare the space station for the future arrival of US commercial crew spacecraft.

NASA is gearing up for to get set towards successful spacewalk. Thomas Pesquet took his excitement to the twitter and said “Going on a spacewalk requires many weeks of planning on Earth and many hours preparing the spacesuits and tools.”

The first spacewalk is scheduled to begin around 8.00 A.M ET today. NASA TV will provide complete coverage which will begin from 6:30 A.M ET. The total of six and half hour spacewalk journey will be broadcasted for the viewers who wish to quench their curiosity about spacewalking and spacecraft. In all NASA will be conducting three spacewalks and the other two spacewalks are scheduled on 30th March, Thursday and 6th April, Thursday.

The first spacewalk will prepare the Pressurized Mating Adapter-3 (PMA-3) for installation of the second International Docking Adapter, which will accommodate commercial crew vehicle dockings. The PMA-3 provides the pressurized interface between the station modules and the docking adapter. PMA-3 will be moved from the port side of the Tranquility module to the space-facing side of the Harmony module, where it will become home for the docking adapter, which will be delivered on a future flight of a SpaceX Dragon cargo spacecraft.

The two spacewalkers will lubricate the latching end effector on the Special Purpose Dexterous Manipulator “extension” for the Canadarm2 robotic arm, inspect a radiator valve suspected of a small ammonia leak and replace cameras on the Japanese segment of the outpost. They will also install on the starboard zero truss a new computer relay box equipped with advanced software for the adapter.

The second spacewalk will feature Kimbrough and Flight Engineer Peggy Whitson of NASA reconnecting cables and electrical connections on PMA-3 at its new home on top Harmony. The third and the final spacewalk will tentatively feature Whitson and Pesquet replacing an avionics box on the starboard truss called an ExPRESS Logistics Carrier, a storage platform. With all three spacewalks complete and Cygnus safely attached Kimbrough, Soyuz MS-02 commander Sergey Ryzhikov and flight engineer Andrey Borisenko plan to undock and return to Earth April 10, landing on the steppe of Kazakhstan around 7:20 a.m. (5:20 p.m. local time).
