All seven crew members started the day measuring their body mass with an instrument that follows Newton’s second law of motion to account for the lack of gravity. Known as SLAMMD, or Space Linear Acceleration Mass Measurement Device, it applies a known force to an astronaut with the resulting acceleration used to calculate the person’s mass.
New station Flight Engineers Michael Hopkins and Victor Glover continued studying how microgravity impacts dexterous manipulation today. Their inputs for the Grip study could help scientists and engineers develop safer, more advanced spacecraft systems and interfaces.
Astronaut Soichi Noguchi of JAXA (Japan Aerospace Exploration Agency) removed a CubeSat deployer from the Kibo laboratory module’s airlock during Monday morning. During the afternoon, he configured life support hardware in the Harmony module.
NASA Flight Engineer Shannon Walker relaxed Monday morning before spending the rest of the afternoon exploring how to manufacture high quality, next generation fiber optic cables in space. Kate Rubins, on her second station mission, studied how water droplets behave in space to help engineers design improved spacecraft fuel and life support systems.
The two station cosmonauts worked on a pair of docked Russian Progress cargo ships, but otherwise relaxed Monday. Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov are winding down several days of cleaning their spacesuits and stowing their tools following Wednesday’s six-hour and 48-minute spacewalk.
