A podcast joked about tracking who’s farthest from Artemis II, so I built the app
During the **Nerdland** podcast they joked about how funny it would be if someone built an app to track who on Earth is farthest away from the Artemis II astronauts while they’re on their free-return trajectory.
That idea stuck with me, so I actually tried building it.
It’s a small MVP web app that uses the official Artemis II / Orion nominal trajectory and then calculates where the opposite point on Earth would be. Around that region, it looks at active flights and computes the real 3D distance between each aircraft and the spacecraft.
The result is:
* which flight is farthest away *right now*, * plus a leaderboard of which flight reached the maximum distance at any moment during the mission.
It’s intentionally lightweight and transparent, simplified physics, Earth as a sphere, everything labeled as predicted where applicable. The goal wasn’t perfect scientific precision, just a fun, physically correct model based on real mission data.
