Artemis II Tracker

Track NASA's Artemis II mission — humanity's first crewed voyage to the Moon since Apollo 17. Artemis II Tracker gives you a real-time window into the historic 10-day mission as four astronauts fly around the Moon aboard the Orion spacecraft. LIVE COUNTDOWN Follow the countdown to launch with a precision timer synced to the latest launch date from Launch Library 2. Updates automatically if the date changes. MISSION TIMELINE A detailed 10-day flight plan with phase tracking, key events, and progress indicators. After launch, the timeline updates in real-time based on actual telemetry data. REAL-TIME TRACKING (Mission Control) When NASA's AROW telemetry activates after liftoff, the app displays live data: distance from Earth, distance to the Moon, velocity, and spacecraft attitude on an interactive cislunar map. SPACE WEATHER (Mission Control) Live data from NASA's DONKI API — solar flares, coronal mass ejections, and geomagnetic storms with radiation risk assessment for the crew. CREW PROFILES Meet the four astronauts: Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch (NASA), and Mission Specialist Jeremy Hansen (CSA).
