Modeling the provenance of the Apollo 16 regolith

[1] The regolith at the Apollo 16 landing site, the only Apollo landing site in the central lunar highlands, contains material derived from a number of sources. A model that accounts for the introduction of basin ejecta and mixing of the megaregolith is used to estimate the abundance of basin material in the Apollo 16 regolith. Megaregolith mixing model estimates of the abundance of primary eje...

Assessment of spectral properties of Apollo 12 landing site

The geology and mineralogy of the Apollo 12 landing site has been the subject of recent studies that this research attempts to complement from a remote sensing point of view using the Moon Mineralogy Mapper (M3) sensor data, onboard the Chandrayaan-1 lunar orbiter. It is a higher spatial-spectral resolution sensor than the Clementine UVVis sensor and gives the opportunity to study the lunar sur...

Autonomous landing at unprepared sites by a full-scale helicopter

Helicopters are valuable since they can land at unprepared sites; however, current unmanned helicopters are unable to select or validate landing zones (LZs) and approach paths. For operation in unknown terrain it is necessary to assess the safety of a LZ. In this paper, we describe a lidar-based perception system that enables a full-scale autonomous helicopter to identify and land in previously...
