Artemis I is a significant mission by NASA aimed at returning humans to the Moon. It serves as the first test flight of the Space Launch System (SLS) rocket and the Orion spacecraft. This uncrewed mission will orbit the Moon, allowing engineers to gather data and ensure everything is functioning correctly for future crewed missions. The mission is part of the broader Artemis program, which seeks to establish a sustainable human presence on the Moon by the end of the decade. By exploring the lunar surface, NASA hopes to gain insights that will pave the way for future missions to Mars and beyond.
