Spacesuits, Human Research, Robotics Training Ahead of Cargo Missions
The six-member Expedition 61 crew juggled spacesuit maintenance and human research activities aboard the International Space Station today. The orbital residents are also getting ready to send off and receive resupply ships.
Two U.S. spacesuits are being serviced ahead of a series of spacewalks planned to repair a cosmic particle detector, also known as the Alpha Magnetic Spectrometer (AMS). Commander Luca Parmitano of ESA (European Space Agency) and NASA astronaut Andrew Morgan are tentatively scheduled to venture outside the station in November and upgrade the AMS thermal control system.
Parmitano also tested a device that measures an astronaut’s mass using Newton’s Second Law of Motion. The device applies a known force to an attached astronaut and the resulting acceleration is used to accurately calculate an astronaut’s mass.
NASA Flight Engineers Jessica Meir and Christina Koch shared maintenance duties on a human organ printer, the BioFabrication Facility. Scientists are testing the 3D biological printing facility for its ability to print more cohesive organ structures in microgravity than on Earth.
Koch and Meir will also be on Canadarm2 robotics duty on Friday and Monday to support a pair of cargo missions. Koch, with Meir backing her up, will command the robotic release of Japan’s HTV-8 resupply ship Friday at 1:20 p.m. EDT. The HTV-8 is wrapping up a 34-day mission attached to the Harmony module.
They will switch roles on Monday when Meir takes charge of the Canadarm2 robotic arm and captures Northrop Grumman’s Cygnus cargo craft at 4:10 a.m. EST. Koch will back her up in the cupola while Morgan monitors the Cygnus’ approach and rendezvous. Cygnus will launch Saturday at 9:59 a.m. atop the Antares rocket from Virginia.
