description: South Pole-Aitken (SPA) basin has been a target of intense study
 since it is one of the largest impact basins in the solar system. It is
 thought that SPA basin excavated deep into the lunar crust and possibly even
 the mantle. Such conclusions have been supported by the observed mafic and
 thorium composition anomalies seen across the entire basin. One of the major
 goals of lunar and planetary science has been to measure and understand the
 composition of the non-mare materials within SPA basin. It is expected that
 this information will help to increase our understanding of the formation and
 differentiation processes that occurred early on the Moon.
