【 摘 要 】

We now know that water ice exists on the lunar surface thanks to the findings of multiple lunar missions such as LRO and LCROSS. However, before we develop systems that can utilize this precious resource at a useful scale, we need to acquire more data about the concentration of water in the lunar regolith and how it may vary by depth and location. The OVEN (Optimized Volatile Extraction Node) system is designed to determine the concentration of water as part of an instrument called WAVE (Water Analysis & Volatile Extraction) which can be deployed during a lunar resource prospecting mission. Experiments were carried out at the Johnson Space Center in order to better understand the potential losses of water that may occur during a prospecting mission when a sample is transferred from a drill to the OVEN. A description of the experiment as well as the results will be presented here.
