how fast will artemis travel to the moon
Artemis II, NASA's upcoming crewed lunar flyby mission launching today (April 1, 2026), will reach the Moon's vicinity in about 3-4 days , peaking at speeds around 28,000-40,000 km/h (17,500 mph) during its trans-lunar injection phase.
Mission Speed Profile
The Orion spacecraft accelerates rapidly post-launch via the SLS rocket:
- T+3 minutes : ~4,990 km/h (3,100 mph) after fairing jettison.
- T+8 minutes : ~28,160 km/h (17,500 mph) at main engine cutoff.
- Peak cruise : Up to 40,000 km/h (25,000 mph) en route, matching Apollo-era velocities for free-return trajectory.
- Reentry : ~40,000 km/h (25,000 mph), shattering records.
These aren't constant speeds—Orion coasts most of the way using gravity assists, not sustained thrust.
Orion's path slingshots around the Moon's far side at ~6,500 km closest approach, then hurtles back in a 10-day loop.
Journey Timeline
- Day 1 : Earth orbit checks, then trans-lunar injection burn.
- Days 2-4 : Cruise to lunar vicinity (arrival ~April 6).
- Day 6 : Flyby peak, 7,600 km beyond Moon—new human distance record.
- Days 7-10 : Return, splashdown after 9 days, 1 hour.
From Artemis I's uncrewed test: Total distance ~1.4 million miles at similar profiles.
Crew & Context
Commander Reid Wiseman , Pilot Victor Glover (first Black astronaut to Moon vicinity), Christina Koch (first woman), and Jeremy Hansen (first non-U.S. citizen) helm this historic flight—first crewed deep space since Apollo 17 (1972).

Artemis I Comparison
Mission| Launch| Duration| Peak Speed| Distance
---|---|---|---|---
Artemis I (2022)| Nov 16| 25 days| ~39,500 km/h reentry| 1.4M miles 5
Artemis II (2026)| Apr 1| 10 days| ~40,000 km/h reentry| ~500K+ miles 7
Shorter trip prioritizes crew safety over exploration.
TL;DR : Artemis hits lunar speeds of 25,000-28,000 mph in days, not hours—gravity-powered efficiency wins.
