In advance of the Thursday spacewalk on ISS, continued science and robotics research continue. Please remember, ongoing scientific activity, along with life-based preparations for any eventuality continue aboard the space station.
The Pressurized Mating Adapter-3 (PMA-3) was robotically removed Sunday from the Tranquility module and attached to the Harmony module after being prepared during a successful spacewalk Friday. A second spacewalk is scheduled for Thursday at 8 a.m. EDT to finalize the PMA-3 cable connections on Harmony.
Commander Shane Kimbrough disconnected cables from PMA-3 while still attached to Tranquility during a spacewalk on Friday. That work allowed ground controllers to use the Canadarm2 robotic arm to remotely grapple and remove PMA-3 from Tranquility and attach it to Harmony.
The relocation readies the PMA-3 for the future installation of the new International Docking Adapter-3 (IDA-3) set to be delivered on a future cargo mission. The IDA-3 will accommodate commercial crew vehicle dockings and provide the pressurized interface between the station and the adapter.
Thursday’s spacewalk will see Kimbrough and Peggy Whitson complete the PMA-3 attachment work on the Harmony’s space-facing port. The duo will also install computer relay boxes containing software upgrades to enable future commercial crew vehicle dockings at the International Space Station.
Earlier, science and robotics research and applications continued this week.
The crew researched the effects of living in space and set up a specialized microscope for a physics experiment today. Two astronauts are also getting ready for a Thursday spacewalk to continue setting up the International Space Station for commercial crew vehicles.
Flight Engineers Peggy Whitson and Thomas Pesquet used a tape measure this morning and measured their arms, legs, hips, waist and chest. Researchers are studying how microgravity impacts body size and shape and compare crew measurements before, during and after a space mission.
Whitson later began setting up gear for the ACE-T-1 (Advanced Colloids Experiment Temperature Cpntrol-1) physics study. She opened up the Fluids Integrated Rack and reconfigured the Light Microscopy Module to research tiny suspended particles designed by scientists and observe how they form organized structures within water.
Commander Shane Kimbrough is getting ready for another spacewalk on Thursday at 8 a.m. EDT. This time he’ll go outside with Whitson to finish cable connections at the Harmony module where the Pressurized Mating Adapter-3 (PMA-3) was robotically attached on Sunday. The PMA-3 relocation gets the adapter ready for the new International Docking Adapter-3 set to be delivered on a future cargo mission.
