Science preparation and procedure reviews topped the schedule aboard the International Space Station on Wednesday. The seven Expedition 74 crew members conducted a variety of tasks to ready for upcoming experiments and to conduct cargo operations.
NASA astronauts Jack Hathaway and Jessica Meir worked separately throughout the day to consolidate food and complete post-spacewalk work following the March 18 spacewalk to install a modification kit on the 2A power channel of the space station ahead of future solar array upgrades. This work included the inspection of the suit glove heaters, data recorders, cameras, and helmet lights.
To prepare for upcoming experiment operations, European Space Agency (ESA) astronaut Sophie Adenot spent the morning cleaning and inserting samples into the Soft Matter Dynamics experiment containers, which explore the dynamics of droplets and their size evolution in emulsions. After donning the RelaxPro actigraphy device earlier this week, Adenot transferred the data to ground teams for analysis. She then familiarized herself with spacesuit systems before loading software onto payload hard drives.
In the Kibo module, NASA astronaut Chris Williams spent a large portion of the day installing new data management system racks, which are used to house and manage data for various science experiments. Later in the day, he worked on food consolidation then inspected medical hardware.
Following yesterday’s arrival of the Progress 94 cargo spacecraft, space station commander Sergey Kud-Sverchkov and flight engineer Sergei Mikaev reviewed cargo transfer and stowage plans as they gear up to unload the nearly three tons of food, fuel, and supplies delivered by the spacecraft.
Later on, Kud-Sverchkov and flight engineer Andrey Fedyaev photographed landmarks across Earth for documentation. Fedyaev also spent time throughout the day conducting some orbital plumbing and reconfiguring station cameras.
