ARTEMIS II
The Opening
Four humans are about to strap themselves to 4 million pounds of thrust and leave Earth. Their destination: a loop around the Moon and back. 10 days. 1.3 million kilometers.
You need a mission that:
├── Accelerates 4 humans to 39,400 km/h
├── Navigates a free-return trajectory
├── Keeps 4 people alive in a 9 m³ capsule
└── Survives re-entry at 40,000 km/h
Let's build the mission.
