Site plan

North up, true scale around the target point. Arrows: where the Sun and the Earth sit on the horizon at touchdown.

The sky from the landing site

Where the Sun and the Earth sit above the horizon from two days before touchdown through the following four weeks. Predicted by JPL Horizons for a smooth Moon: hills and crater walls are not included, and near the poles they can hide a Sun that is a degree or two up.

Sun up: 50% of the window
Next sunset: 2023-05-09 03:00 UTC
Earth up: 100% of the window
Earth elevation: 22.5° to 34.7°

Engine plume: reference distances

155 mApollo 12 → Surveyor 3. Apollo 12 landed about 155 m from Surveyor 3, and its plume sandblasted the older lander. source
600 m1 cm gravel, Apollo-sized lander. Gravel 1 cm across leaves a Lunar Module–sized lander's plume at about 30 m/s and lands within 600 m; NASA gives up to about 1.5 km for 1–10 cm rocks. source
2 kmNASA heritage-site standoff. NASA recommends targeting touchdown at least 2 km from U.S. lander heritage sites (0.5 km from impact sites). source

No CLPS or Artemis lander has a published plume keep-out distance; these are reference cases, drawn around the target point, not limits for this lander. Fine dust leaves a plume at up to kilometres per second and is not stopped by any ring. No recorded hardware is within 2 km of the target point.

Hardware already nearby

No recorded landing or impact site within 150 km of the target.
