What is Artemis II?
Artemis II is NASA's first crewed mission to the Moon since Apollo 17 in 1972. Four astronauts orbit the Moon in the Orion spacecraft on a ~10-day free-return trajectory, testing systems for future lunar landings.
Is this tracker real-time?
Yes. The tracker fetches fresh trajectory vectors from NASA's JPL Horizons ephemeris service every 5 minutes.
Why does the trajectory curve?
Artemis II follows a free-return trajectory using lunar gravity to return to Earth.
What do the trail colors mean?
Each color represents a mission phase: orange for Launch, yellow for Earth Orbit, green for TLI, blue for Outbound, purple for Lunar Flyby, cyan for Return, pink for Re-entry.
How close does Orion get to the Moon?
At perilune, Orion passes approximately 6,600 km above the lunar surface.
Who are the Artemis II crew?
Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Mission Specialist Jeremy Hansen (CSA/Canada).
What is JPL Horizons?
JPL Horizons is NASA's ephemeris computation service. This tracker uses NAIF ID -1024 for the Orion spacecraft.
