Station Gears Up for Spacewalk During Advanced Science Work












ISS - Expedition 56 Mission patch.

August 13, 2018

Two Expedition 56 cosmonauts packed a Russian resupply ship today before preparing for Wednesday’s spacewalk. The other four International Space Station crew members worked on a variety of space science experiments and lab maintenance duties.

Cosmonauts Oleg Artemyev and Sergey Prokopyev are loading a Progress 69 (69P) cargo craft with trash ahead of its departure next week. The 69P delivered over three tons of food, fuel and supplies in February. The spacecraft will undock on Aug. 22 for a fiery disposal over the Pacific Ocean one week later after a series of engineering tests.

The cosmonauts then turned their attention to Wednesday’s spacewalk when they will hand-deploy four tiny satellites, install antennas and cables and collect exposed science experiments. They continued setting up their spacewalking gear inside the Pirs airlock today. They will exit Pirs Wednesday at 11:58 a.m. EDT for about six hours of work outside the station’s Russian segment inside their Orlan spacesuits. NASA TV’s live coverage of the spacewalk begins at 11:15 a.m.

Commander Drew Feustel and Flight Engineer Serena Auñón-Chancellor performed the majority of the science work today onboard the orbital complex. Feustel explored how proteins crystallize and grow in microgravity to help scientists develop safer, more advanced drug therapies on Earth. Auñón-Chancellor started her day with a blood draw before researching radio spectrum usage in space which may benefit satellite communications. Finally, she studied the sedimentation of quartz and clay particles possibly assisting future planetary exploration missions and the petroleum industry on Earth.

Flight Engineer Ricky Arnold spent some time inspecting U.S. spacesuit lights and replacing fan filters before assisting Feustel with the protein crystal growth experiment. Alexander Gerst of ESA checked out U.S. spacesuit batteries then moved on to verifying the functionality of fire extinguishers and breathing masks.
