That would mark the first launch of U.S. astronauts from U.S. soil since the space shuttle fleet\u2019s retirement in 2011.<\/p>\n<p><iframe title=\"Spacewalk prepares ISS for commercial crew\" src=\"https:\/\/www.youtube.com\/embed\/4cQKkY_DBQc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\" data-ratio=\"0.5625\" data-width=\"800\" data-height=\"450\" style=\"display: block; margin: 0px; width: 800px; height: 450px;\"><\/iframe><\/p>\n<p>Unhooking the PMA-3\u2019s connections is just one step in the installation procedure. Astronauts plan to use the station\u2019s robotic arm to move the adapter from the Tranquility module to its new spot on the Harmony module on Sunday.<\/p>\n<p>Kimbrough and NASA\u2019s Peggy Whitson will reconnect the cables and wires during a second spacewalk, set for March 30. They\u2019ll also install shields and covers on the now-vacant Tranquility port.<\/p>\n<p>Whitson and Pesquet will take on a third spacewalk to replace an avionics box on the station\u2019s truss. The box contains electrical equipment and the electronics for science experiments and other hardware stored outside the station.<\/p>\n<p>The replacement box is due to be sent to the station in an Orbital ATK Cygnus robotic cargo capsule. The Cygnus\u2019 launch date&nbsp;is currently up in the air, due to a booster hydraulic issue relating to its Atlas 5 launch vehicle. If the issue can be resolved in time, the third spacewalk is targeted for April 6.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>French astronaut Thomas Pesquet makes contact with the International Space Station\u2019s robotic arm during a spacewalk.
