“…It is assumed that outgassing is caused by volatiles released from mineral decomposition rather than from surface desorption. Similar conclusions were drawn by Street et al (2010), ten Kate et al (2010), and Glavin et al (2012), who measured a release of CO 2 , SO 2 , H 2 S, and S between 300 °C and 600 °C. Table 2 lists the major mineral phase abundances of NU-LHT-2M for particles with a single phase (99.2 % of all particle compositions are a single phase).…”

The present work describes the end-to-end demonstration of enriching the lunar highland regolith simulant NU-LHT-2M with loosely adsorbed water, releasing this and other volatile compounds by thermal treatment in high-vacuum, and identifying the released volatile species through mass spectrometry. This demonstration was performed to characterise how different sample conditions will affect the in-situ measurements performed by the ProSPA gas analysis instrument that is to operate at the lunar south pole on board the Russian Luna-27 lander. A laboratory breadboard was set up that allows testing of variable parameter combinations, such as different initial water contents, particle sizes, quantities, and bulk densities of the sample, as well as different heating rates. Three distinct temperature-dependent phases of outgassing were identified. Between-50 °C and 300 °C loosely adsorbed volatiles, mainly water in a mass fraction of around 0.1 % to 0.2 %, were released from the samples. Above that the samples showed mineral decomposition which led to the release of trapped water, carbon dioxide, and hydrogen sulfide. It was shown that the gas pressure produced by outgassing of the volatile species in a continuously pumped system is noticeably higher if the sample is larger, contains smaller particles, or if a higher heating rate is applied. Highlights  NU-LHT-2M was hydrated with water in mass fractions around 0.1 %  In a ProSPA-like laboratory breadboard the water was extracted by heating  NU-LHT-2M releases the added volatile water below a temperature of °C  Different sample conditions develop different characteristic gas pressures  NU-LHT-2M releases trapped water, CO 2 , and H 2 S from decomposition above 300 °C

“…The extraction and identification of volatile resources including water, oxygen, and hydrocarbons from the regolith on the Moon can be done by vacuum pyrolysis at elevated temperatures that releases volatiles trapped inside solid samples. With a high temperature pyrolysis oven coupled to a time-of-flight mass spectrometer instrument called Volatile Analysis by Pyrolysis of Regolith (VAPoR), solid samples can be heated to high temperatures in vacuum to determine the composition of volatiles released as a function of temperature [20,21].…”

“…This small dome creates a vacuum tight seal and the system is pumped down to vacuum, typically to the 10 -7 torr region. The sample is then heated to 1000 o C at a rate of 20 o C/minute and the gases that evolve from the sample are then analyzed by the mass spectrometer [4] [5].…”

Rover-based 2012 Moon and Mars Analog Mission Activities (MMAMA) scientific investigations were recently completed at Mauna Kea, Hawaii. Scientific investigations, scientific input, and science operations constraints were tested in the context of an existing project and protocols for the field activities designed to help NASA achieve the Vision for Space Exploration. Initial science operations were planned based on a model similar to the operations control of the Mars Exploration Rovers (MER). However, evolution of the operations process occurred as the analog mission progressed. We report here on the preliminary sensor data results, an applicable methodology for developing an optimum science input based on productive engineering and science trades and the science operations approach for an investigation into the valley on the upper slopes of Mauna Kea identified as "Apollo Valley."
