The first <a href=\"https:\/\/www.nasa.gov\/press-release\/nasa-tv-to-air-preview-briefing-three-us-spacewalks\" rel=\"noopener\">spacewalk remains on schedule<\/a> for Friday, March 24. A second spacewalk has been rescheduled to Thursday, March 30, and a third spacewalk now is scheduled for Thursday, April 6.<\/p>\n\n\n\n<p>NASA TV will provide complete coverage beginning each day at 6:30 a.m. EDT, with the six-and-a-half hour spacewalks scheduled to begin about 8 a.m.<\/p>\n\n\n\n<p>The first spacewalk will prepare the Pressurized Mating Adapter-3 (PMA-3) for installation of the second <a href=\"https:\/\/www.nasa.gov\/feature\/meet-the-international-docking-adapter\" rel=\"noopener\">International Docking Adapter<\/a>, which will accommodate commercial crew vehicle dockings. The PMA-3 provides the pressurized interface between the station modules and the docking adapter. Expedition 50 Commander Shane Kimbrough of NASA and Flight Engineer Thomas Pesquet of ESA (European Space Agency) will disconnect cables and electrical connections on PMA-3 to prepare for its robotic move Sunday, March 26. 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 spacewalkers also will install on the starboard zero truss a new computer relay box equipped with advanced software for the adapter.<\/p>\n\n\n\n<p>The two spacewalkers will lubricate the latching end effector on the Special Purpose Dexterous Manipulator \u201cextension\u201d for the <a href=\"https:\/\/www.nasa.gov\/audience\/foreducators\/k-4\/features\/F_Canadian_Crane.html\" rel=\"noopener\">Canadarm2<\/a> robotic arm, inspect a radiator valve suspected of a small ammonia leak and replace cameras on the Japanese segment of the outpost. Radiators are used to shed excess heat that builds up through normal space station operation.<\/p>\n\n\n\n<p>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. They also will install the second of the two upgraded computer relay boxes on the station\u2019s truss and install shields and covers on PMA-3 and the now-vacant common berthing mechanism port on Tranquility.<\/p>\n\n\n\n<p>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. The box houses electrical and command and data routing equipment for the science experiments and replacement hardware stored outside of the station. The new avionics box is scheduled to launch on the upcoming Orbital ATK Cygnus cargo spacecraft mission.<\/p>\n\n\n\n<p>This will be the 198th, 199th and 200th spacewalks in support of space station assembly and maintenance. Kimbrough\u2019s two spacewalks will be the fifth and sixth of his career. Whitson will be making the eighth and ninth spacewalks of her career \u2013 more than any other female astronaut. Pesquet will undertake the second and third spacewalks in his career.<\/p>\n\n\n\n<p>Get NASA TV streaming video, schedule and downlink information at:<\/p>\n\n\n\n<p><strong>https:\/\/www.nasa.gov\/nasatv<\/strong><\/p>\n\n\n\n<p>Learn the latest on the International Space Station, its crew and their research at:<\/p>\n\n\n\n<p><strong>https:\/\/www.nasa.gov\/station<\/strong><\/p>\n\n\n\n<p>-end-<\/p>\n\n\n\n<p>Cheryl Warner<br>\nHeadquarters, Washington<br>\n202-358-1100<br>\ncheryl.m.warner@nasa.gov<br>\nDan Huot<br>\nJohnson Space Center, Houston<br>\n281-483-5111<br>\ndaniel.g.huot@nasa.gov<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Expedition 50 astronauts will conduct up to three spacewalks outside the International Space Station (ISS) in late March and early April to prepare for the future arrival of U.S. commercial crew spacecraft and upgrade station hardware.
