ISS - Expedition 64 Mission patch.
Feb. 3, 2021
The Expedition 64 crew turned its attention to science hardware today following Tuesday’s harvest aboard the International Space Station. The orbital residents also cleaned up following two spacewalks to upgrade communications and power systems.
NASA Flight Engineer Michael Hopkins prepared the NanoRacks Bishop airlock on Wednesday for its upcoming pressurization. The experienced astronaut then finished the day inside the SpaceX Crew Dragon spaceship recharging computer tablets and updating orbital software.

The day before, Hopkins picked a variety of edible plants growing in the station’s Columbus laboratory module including pak choi, wasabi mustard, kale, and red romaine. He snacked on the leaves with his crewmates for a taste test and stowed samples for later analysis as part of the Veg-3 botany study. Space agriculture is key to the success and sustainability of future human missions to the Moon, Mars and beyond.
Astronauts Kate Rubins and Victor Glover split their day servicing hardware for a long-running suite of experiments known as ACME, or Advanced Combustion in Microgravity Experiments. The duo replaced a variety of components inside the device that hosts the fuel efficiency, pollution and fire safety investigations.

Glover started the day with fellow NASA astronaut Shannon Walker tearing down old video equipment that he and Hopkins uninstalled from Columbus during Monday’s spacewalk. Walker then joined JAXA astronaut Soichi Noguchi for post-spacewalk maintenance on the U.S. spacesuits Hopkins and Glover wore on Monday.
In the Russian segment of the station, Commander Sergey Ryzhikov worked on Zarya module upkeep and science photography tasks. Flight Engineer Sergey Kud-Sverchkov assisted Ryzhikov with the science photography then moved on to communications and life support work.
