Two Expedition 54 astronauts continue preparing for Monday’s upcoming spacewalk to wrap up robotics repair work. The crew is also working on a variety of science gear to ensure the orbital laboratory is in tip-top shape.
Flight Engineer Mark Vande Hei is going outside the International Space Station again for this year’s second spacewalk. This time he’ll work with Japanese astronaut Norishige Kanai to finish maintenance on a Latching End Effector, or the robotic hand of the Canadarm2 robotic arm. That work was started Tuesday when Vande Hei partnered with NASA astronaut Scott Tingle during a seven-hour and 24-minute spacewalk. Monday’s spacewalk begins at 7:10 a.m. EST with live NASA TV coverage beginning at 5:30 a.m.
As usual, advanced microgravity research is ongoing inside and outside the space station. This morning, veteran station astronaut Joe Acaba tended to a pair of science freezers ensuring they maintain proper temperatures for the stowage of biological samples. Kanai checked out a 3D printed satellite deployer that will spring-launch four tiny satellites known as FemtoSats from the station.
