Apollo 14 Deploys ALSEP

Explanation: After the lunar module of Apollo 14 set down on the Moon , Astronauts Alan Shepard and Edgar Mitchell deployed the Apollo Lunar Surface Experiments Package (ALSEP) and collected samples of lunar material. The ALSEP scientific experiments included a seismometer sensitive to slight lunar surface movements, and charged particle detectors which measured the solar wind . The seismometer successfully measured surface tremors interpreted as moonquakes and meteoroids striking the Moon , while the solar wind experiment was sensitive enough to detect the element argon . These and other ALSEP experiments helped classify the internal structure and magnetic field of Earth's Moon . Shepard and Mitchell also made a geology traverse to the rim of Cone Crater, carrying their tools and sample containers in the Modular Equipment Transporter (MET). In this picture Alan Shepard assembles a core tube which he will then hammer into the surface.
