Apollo vs Artemis: NASA's Two Crewed Moon Programs
Apollo (1961–1972) and Artemis (2017–present) are the only two human programs to send people beyond low Earth orbit. They share a destination — the Moon — but the technology, goals, and political context are very different.
Apollo (1961–1972)
- Goal: Land Americans on the Moon before the Soviets
- Crewed lunar missions: 9 (6 landings)
- People on the Moon: 12 (all American men)
- Rocket: Saturn V
- Spacecraft: Command + Service Module + LM
- Total program cost: ~$28B (1973) ≈ $260B (2026 dollars)
Artemis (2017–present)
- Goal: Sustainable lunar return + first Mars step
- Crewed missions to date: 1 (Artemis II, 2026)
- People returning to Moon: 4 announced; first woman + first non-American
- Rocket: SLS (Space Launch System)
- Spacecraft: Orion + (planned) SpaceX Starship HLS
- Estimated total cost through Artemis III: ~$93B
The Strategic Difference
Apollo was designed to get there fast and prove a political point — beating the Soviet Union to the Moon. Once that was achieved, the missions stopped (Apollo 18, 19, and 20 were cancelled). Artemis is designed to stay: build a lunar Gateway space station in Moon orbit, establish a base near the lunar south pole, and use the Moon as a proving ground for crewed Mars missions in the 2030s–2040s.
Side-by-Side Hardware
| Component | Apollo | Artemis |
|---|---|---|
| Heavy-lift rocket | Saturn V (110 m, 2.8M kg) | SLS Block 1 (98 m, 2.6M kg) |
| Crew capsule | Apollo Command Module (3 crew) | Orion (4 crew) |
| Crew capsule mass | 5,800 kg | 10,400 kg |
| Lunar lander | Apollo Lunar Module (NASA-built) | SpaceX Starship HLS (commercial) |
| Lunar destination | Equatorial regions | South pole (water ice) |
| International partners | None (U.S. only) | ESA, JAXA, CSA + 50+ Artemis Accord nations |
| Crew demographic | All American men | First woman, first person of color, first non-American |
Why the South Pole This Time?
The Moon's south polar craters contain permanently shadowed regions (PSRs) where temperatures stay below −163°C and water ice has accumulated for billions of years. Water ice is the single most valuable resource for sustained lunar presence — it provides drinking water, breathable oxygen, and (when split) hydrogen rocket fuel. Apollo couldn't land near the poles for fuel and lighting reasons; modern propulsion and computing make it routine.
What Apollo Did That Artemis Hasn't (Yet)
Apollo landed humans on the Moon six times in three years and returned 382 kg of lunar samples. Artemis has so far flown one uncrewed mission (Artemis I, 2022) and one crewed lunar flyby (Artemis II, 2026). The first crewed landing — Artemis III — is planned for 2027, though the schedule has slipped multiple times. Apollo also did one thing Artemis is unlikely to repeat: ran six successful crewed lunar landings in a single decade.
