Earth landing coordinates:

Recovery ship:

USS Okinawa (crew onboard in 40 min.)

Mission objectives:

Lunar landing mission to perform selenological inspection, survey, and sampling in the Hadley-Apennine region; deploy an ALSEP; evaluate durability of Apollo equipment; evaluate longer EVAs; conduct in-flight experiments and photography; evaluate the lunar roving vehicle.

Results:

All objectives were achieved. The lunar roving vehicle (LRV-I) increased the range and scientific return of lunar surface operations; during the three EVA periods the LRV traversed 27.9 km at speeds of up to 12-13 kph. The vehicle's controllability and climbing capability were demonstrated. The crew collected 76.7 kg of lunar material. A satellite was released from the CSM on Aug. 4 which was used for scientific experiments its lunar orbit was 141.3 x 102 km.
