Step-by-step explanation:
Research on the ISS improves knowledge about the effects of long-term space exposure on the human body. Subjects currently under study include muscle atrophy, bone loss, and fluid shift. The data will be used to determine whether space colonization and lengthy human spaceflight are feasible.
The three-week-long Artemis 1 spaceflight aims to travel 280,000 miles from the Earth and thousands of miles beyond the Moon before returning home. Crewed Artemis missions will follow, culminating in humans returning to the Moon's surface by 2024.
