The splashdown point was estimated to be 26°13′ N, 158°13′ W, 330 statute miles (530 km) north of Honolulu, Hawaii and 9.8 km (5.3 n mi) from the recovery ship USS Okinawa.

The first of the longer J-class expedition-style lunar landing missions was also the first to include the lunar rover, a car-like vehicle that extended the astronauts' range. The lunar module Falcon touched down near the sinuous channel known as Hadley Rille. Scott and Irwin rode more than 17 miles (27 kilometers) in their rover, and had a free hand in their geological field studies compared to earlier lunar astronauts. They brought back one of the prize trophies of the Apollo program—a sample of ancient lunar crust nicknamed the "Genesis Rock", and returned with total 76.8 kg of lunar samples.
David Scott performed an informal experiment, simultaneously dropping a falcon feather and a hammer. Both hit the ground at the same time, verifying that (within the accuracy of the crude setup) bodies fall at the same rate regardless of mass.
Apollo 15 also launched a small subsatellite for measuring particles and fields in the lunar vicinity. On the way back to Earth, Worden, who had flown solo on board Endeavor while his crewmates walked on the surface, conducted the first space-walk between Earth and the Moon to retrieve film from the side of the spacecraft.
Relics
The command module is displayed at the United States Air Force Museum, Wright-Patterson Air Force Base, Dayton, Ohio and the lunar module impacted the Moon on 3 August, 1971 at 26.36° N, 0.25° E.
