Context: Artemis II mission
NASA’s Artemis II will send humans beyond low-Earth orbit (first time after Apollo 17) to test systems before a Moon landing.

1. Artemis Programme
• Artemis I — 2022 → Uncrewed test
• Artemis II — 2026 → Crewed Moon flyby (no landing)
• Artemis III — 2027–28 → Human Moon landing
2. Core Systems
SLS (Space Launch System)
• NASA’s heavy-lift rocket
• Work: Carries astronauts + Orion from Earth to space
Orion Capsule
• Crew vehicle
• Work: Carries astronauts, life support, re-entry
HLS (Human Landing System)
• Built by SpaceX
• Work: Takes astronauts from lunar orbit → Moon surface
3. Artemis II (What exactly happens)
• 4 astronauts
• ~10-day mission
• Travel → Earth → Moon orbit → return
• Purpose → Test entire system (SLS + Orion + humans in deep space)
4. Why Moon again
• Water ice at poles → fuel + life support
• Base for Mars missions
• Strategic presence in space
