See the mission unfold
Watch Orion’s flight path come to life on an interactive 2D map. The app visualizes actual mission trajectory data so you can follow along from Earth departure to lunar arrival and back — no aerospace degree required.

Tap to explore
Curious about a specific moment in the mission? Tap anywhere along Orion’s orbit path to surface real trajectory data — including the spacecraft’s position, velocity, UTC time, and Julian Date at that point. It’s like having mission control on your iPhone, iPad, VisionPro, and Mac.
