    Cargo Headed to Station, Week Begins with Science Prep and Maintenance

    ESA (European Space Agency) astronaut and Expedition 74 Flight Engineer Sophie Adenot is pictured inside the International Space Station's Harmony module during cargo stowage activities.

    A cargo spacecraft is in orbit catching up to the International Space Station for a docking tomorrow to deliver food and supplies to the Expedition 74 crew. Aboard the orbital lab, the seven residents kicked off the week with science operations prep, routine maintenance, and getting systems ready for a future spacewalk.

    Week Wraps with Health Research and Spacewalk Closeout Procedures

    Expedition 74 Flight Engineers Jessica Meir and Chris Williams, both NASA astronauts, collect frozen research samples from inside the International Space Station's Destiny laboratory module. The samples were stowed inside science freezers aboard a SpaceX Dragon spacecraft for retrieval and analysis on Earth.

    Health research and final spacewalk closeouts wrapped up the week for the Expedition 74 crew members aboard the International Space Station as they gear up to receive a cargo delivery next week. Understanding how the human body reacts to space is key to ensure crews thrive on future longer-duration missions. Residents aboard the orbital complex […]

    Crew Enjoys Light-Duty Day, Debriefs Spacewalk

    The International Space Station was soaring 263 miles above the Pacific Ocean near the island of Hawaii when this 30‑second long‑duration photograph was taken, revealing Earth’s atmospheric glow and star trails at approximately midnight local time.

    Four International Space Station residents had a light-duty day Thursday as they enjoyed some time off and worked on close out procedures following the conclusion of yesterday’s spacewalk. The three other Expedition 74 crew members spent the day inspecting various modules of the orbital complex, cleaning, and stowing cargo.

    Spacewalkers Exit Station for Solar Array Mod Kit Install

    From left, NASA astronauts Jessica Meir and Chris Williams are conducting a spacewalk to install a modification kit and route cables on the port side of the International Space Station where a new roll-out solar array will be attached on a future spacewalk.

    NASA astronauts Jessica Meir and Chris Williams began a spacewalk at 8:52 a.m. EDT to prepare the 2A power channel for the future installation of new roll-out solar arrays. Once installed, the arrays will provide additional power for the orbiting laboratory, supporting critical systems and its safe, controlled deorbit.

    Crew Wraps Final Spacewalk Preparations

    NASA astronaut and Expedition 74 flight engineer Jessica Meir’s reflection is captured in a spacesuit helmet visor. The visor assembly is coated with a microscopic layer of gold that reflects infrared radiation to protect an astronaut’s eyes while allowing visible light to pass through. Meir was working inside the International Space Station's Quest airlock, installing leg and arm components on the spacesuit and swapping components from one suit to another.

    Tuesday brought the final preparations for tomorrow’s spacewalk where two NASA astronauts will exit the International Space Station and enter the vacuum of space for space station solar array upgrade work. The Expedition 74 crew members prepped spacesuits and reviewed procedures while working in some time for maintenance and science activities.
