Much of the first EVA was ed to deploy a set of experiments, some of which continued to radio data back to Earth until September 1977. Among these was a seismometer, which detected thoands of moonquakes and helped to determine the structure of the Moon's interior. Other instruments measured theposition of the solar wind and the Moon's tenuo atmosphere and plasma environment. Shepard and Mitchell also collected rock and soil samples up to 200 meters west of the landing site.
