4 inch patch. The Apollo 12 mission was the first opportunity in the scientific exploration of the Moon to sample extensively the rocks within half a kilometer of the landing site.

The landing site was at 23 degrees 4 minutes west longitude and 3 degrees 2 minutes south latitude, approximately 120 kilometers (75 miles) southeast of Lansberg Crater and due north of the center of Mare Cognitum. The landing site is near a ray associated with the Copernicus Crater, which is approximately 370 kilometers (230 miles) to the north, and is characterized by a distinctive cluster of craters ranging from 50 to 400 meters in diameter.During two moon walks totaling 7 hours and 45 minutes, the astronauts collected lunar soil and additional surface samples along a geologic traverse. Commander Charles Conrad Jr. and Lunar Module Pilot Alan Bean obtained material from the bottom of a shallow trench and brought back several items from the Surveyor 3 spacecraft. The astronauts caught some of the solar wind in an aluminum foil, and they took photographs of the lunar surface and crew activities with 70-mm Hasselblad cameras and a close-up stereoscopic camera.
