On January 7, 2021, NASA astronaut Kate Rubins serviced samples for Bacterial Adhesion and Corrosion. This investigation looked at how spaceflight affects the formation of microbial biofilms and tested a silver-based disinfectant.NASA This November marks a quarter century of continuous human presence aboard the International Space Station, which has served as a springboard for developing a low Earth economy [...]
NASA Former NASA astronaut Shane Kimbrough is photographed as he left the airlock hatch during a spacewalk on Jan. 13, 2017. Kimbrough performed nine spacewalks during his three spaceflights. He retired in July 2022. Astronauts conduct spacewalks to perform maintenance on the space station, install new equipment, or deploy science experiments. These activities also inform future [...]
