Lunar Volatiles Scout
The Lunar Volatiles Scout (LVS) is an instrumented drill for the in situ characterization of planetary soil samples and volatiles. The cavity drill can be used to drill to a depth of approx. 10 cm in icy regolith. This is then heated to 400 °C using a built-in heating element to dissolve volatile substances such as water. A built-in miniaturized ion trap mass spectrometer (ITMS) and built-in pressure sensors enable live analysis of the dissolved gases. By minimizing interference with the sample, the risk of loss of volatile substances during the otherwise necessary sampling is avoided. This allows the sample to be characterized in its original state, which is a significant advantage over conventional instruments for the analysis of soil samples.
The main field of application of the LVS is the prospection of volatile lunar resources such as water. Its low weight and volume allow it to be used on mobile rovers to cover large areas on the lunar surface. The LVS can also be used on stationary platforms and is also used on other atmosphereless celestial bodies.
