ISS024-E-007737 (10 July 2010) --- NASA astronaut Tracy Caldwell Dyson, Expedition 24 flight engineer, uses a vacuum cleaner during housekeeping operations in the Kibo laboratory of the International Space Station.

Astronaut Tracy Caldwell Dyson speaks on NASA TV prior to the Green Run hot fire test of the core stage for NASA’s Space Launch System (SLS) rocket at Stennis Space Center near Bay St. Louis, Mississippi, on Saturday, January 16, 2021. NASA conducted a hot fire test of the core stage’s four RS-25 engines on the B-2 Test Stand at Stennis. Scheduled for as long as eight minutes, the engines fired for a little more than one minute to generate a combined 1.6 million pounds of thrust, just as will occur during an actual launch. The hot fire is the final test of the Green Run test series, a comprehensive assessment of the SLS core stage prior to launching the Artemis I mission to the Moon.
