The Artemis Program: A Brief Overview

NASA's Artemis program is named after the twin sister of Apollo and the goddess of the Moon in Greek mythology. The program's goal is to return humans to the Moon and establish a sustainable presence by the end of the decade. Artemis I, an uncrewed mission, successfully demonstrated the capabilities of the Space Launch System (SLS) and the Orion spacecraft in 2022. Now, Artemis II will follow suit with a crewed mission, pushing boundaries and testing all the systems in preparation for future lunar landings.
