NASA astronaut Christina Koch stands inside Kennedy Space Center’s Vehicle Assembly Building on July 14, 2021, in front of the agency’s Space Launch System (SLS) rocket that will power the Orion spacecraft on the Artemis I mission later this year. Artemis I will be an uncrewed flight test of Orion and SLS as an integrated system ahead of missions with astronauts. Under Artemis, NASA aims to land the first woman and first person of color on the Moon and establish a long-lasting presence on and around the Moon while preparing for human missions to Mars.
