International Space Station

A full suite of human health research kept the Expedition 73 crew busy Tuesday aboard the International Space Station.

The Expedition 73 crew members are kicking off a busy week aboard the International Space Station. Technology development, space botany, and clean up following last Thursday’s spacewalk topped Monday’s schedule.

The Expedition 73 crew members are cleaning up after a spacewalk on Thursday to upgrade power systems on the International Space Station. The lab residents also continued research and maintenance activities aboard the orbital outpost.

NASA astronauts Anne McClain and Nichole Ayers concluded their spacewalk at 2:49 p.m. EDT. The total time was 5 hours and 44 minutes. It was the third spacewalk for McClain and the first for Ayers, and the 275th spacewalk in support of space station assembly, maintenance, and upgrades.  McClain and Ayers completed their primary objectives, including […]

NASA astronauts Anne McClain and Nichole Ayers began a spacewalk at approximately 9:05 a.m. EDT to install a mounting bracket to prepare for the future installation of an additional set of International Space Station Rollout Solar Arrays. The astronauts also will relocate a space station communications antenna.  

NASA’s live coverage is underway on NASA+ as two astronauts prepare to conduct a spacewalk outside the International Space Station. The spacewalk is scheduled to begin at approximately 8:15 a.m. EDT and last about six and a half hours. 

At 6:10 p.m. EDT today, the Progress 91 spacecraft thrusters fired for 3 minutes, 33 seconds to raise the orbit of the International Space Station to provide an extra distance margin from a piece of orbital debris originating from a Chinese Long March rocket body launched in 2005.

Two NASA astronauts spent Wednesday finalizing preparations for a spacewalk to upgrade the International Space Station’s power generation capabilities and relocate a communications antenna. Expedition 73 Flight Engineers Anne McClain and Nichole Ayers began their shift staging their spacesuits and organizing their spacewalking tools inside the Quest airlock.

The Expedition 73 crew is learning how to manufacture nanomaterials today possibly leading to new therapeutics, vaccines, and regenerative medicine. The orbital residents also conducted vein scans and wrapped a cellular gravity sensing experiment aboard the International Space Station.

Biotechnology, human health, and space botany kicked off the research week aboard the International Space Station on Monday. The Expedition 73 crew is also preparing for a spacewalk on Thursday to ready the orbital outpost for a new rollout solar array and relocate a communications antenna.
