Greek mythology: Artemis is the name of a Greek Goddess. She was the daughter of Zeus and Leto, the sister (some myths even claim she's the twin sister) of Apollo. She was a member of the Twelve Olympian Gods. Artemis was the Goddess of the Arts, and Alchemy. Her Latin name is Diana. (She is represented on Major Arcana Card XIV of the Aleister Crowley Tarot).
Artemis Program and Artemis Accords: The Artemis Accords are an international agreement between governments participating in the Artemis Program, an American-led effort to return humans to the Moon by 2025, with the ultimate goal of expanding space exploration. (Wikipedia). The accords were first signed on 13 October 2020. Since then, more and more countries have joined the initiative.
Notably absent are ESA, Russia, and China, whose main gripe is that the accords give too much prominence to NASA.
