Description

We propose a sensor system capable of remotely probing the molecular composition of cold solar system targets (asteroids, comets, planets, moons), such as from a spacecraft orbiting the target.

The spacecraft would be equipped with a high-power laser and an infrared spectrometer, both powered by photovoltaics. The laser is directed at a spot on the target, with central flux in the 10 MW/ m2 range.
