Two of the penetrators are planned to land near the Apollo 11 and Apollo 12 landing sites, taking advantage of seismic data gathered there from 1969 to 1974. The payload of the orbiter will total  and include astrophysics experiments, dust monitors, plasma sensors, including the LORD astronomy payload, designed to study ultra-high-energy cosmic rays.
Furthermore, seismic experiments were planned, including the use of four penetrators, which will slam into the lunar surface equipped to detect seismic signals. These experiments are expected to help clarify the origin of the Moon.
