ASE used a thumper device and a Mortar (weapon), mortar with explosive charges to explore subsurface lunar structure and Elastic properties of the elements (data page), elastic properties. The experiment's principal investigator was Robert Kovach of Stanford University. The experiment was succeeded on Apollo 17 by the Lunar Seismic Profiling experiment. Experiment The ASE consisted of three major components. A set of three Geophone, geophones was laid out in a line by an astronaut from the Central Station to detect the explosions.Brzostowski and Brzostowski, pp 414-416 A mortar package was designed to lob a set of four grenades varying distances away from the ALSEP. Ranging of the grenade was achieved through the assumption of ideal Ballistics, ballistic trajectories. Finally, an astronaut-activated "Thumper" was used to Detonation, detonate one o ...
