Crew Starts Week With Spacewalk Preps, Satellite Work













ISS - Expedition 63 Mission patch.

June 15, 2020

The Expedition 63 crew is starting the week getting ready for a pair of upcoming spacewalks and a satellite deployment. The International Space Station residents are also setting up research gear that will analyze hazardous particles and plasma crystals.

The three NASA astronauts onboard the station teamed up today setting up hardware and reviewing plans for two spacewalks planned to start at the end of the month. Commander Chris Cassidy and Flight Engineer Bob Behnken checked out rechargeable batteries that will power up U.S. spacesuit components. Flight Engineer Doug Hurley looked at procedures to put on the spacesuits as well as steps a spacewalker would take during an emergency.

The spacewalks will continue power upgrades begun last year on the outside of the space station. Cassidy and Behnken will replace old nickel-hydrogen batteries with new lithium-ion batteries on the Starboard-6 truss segment. The batteries store and distribute power collected from the solar arrays throughout the station.

Cassidy started Monday in Japan’s Kibo laboratory module readying a 110-kilogram Red-Eye satellite for deployment in the next couple of weeks. He installed the satellite inside Kibo’s airlock where it will be placed into the vacuum of space and ejected into orbit from the NanoRacks Kaber Microsat deployer. Red-Eye, the second of three microsatellites, will test satellite communications, flight computers and thermal management technologies.

Behnken helped out with the Red-Eye work before installing the new Mochii microscope in the Kibo lab where it will analyze particles that could threaten crew health and spacecraft safety. Hurley worked in the European Columbus laboratory module making room for the new European Drawer Rack-2 that will support a variety of new space experiments.

The two cosmonauts in the Russian segment of the station kept up their schedule of microgravity research and life support operations. Veteran Flight Engineer Anatoly Ivanishin serviced hardware that observes plasma crystals which could lead to improved research methods and new spacecraft designs. First time space-flyer Ivan Vagner checked space radiation readings and set up Earth observation hardware.
