Description:

Proposals are invited to focus on planetary analog samples analysis by using various laser mass spectrometry methods, in support of instrument development in Planetary Environments Laboratory for current or future space missions to Mars, Ocean Worlds, and other airless bodies. Studies should take advantage of existing mass spectrometry and related laboratory facilities (e.g., commercial and prototype ion trap and TOF mass spectrometers, facility GC-MS and LC-MS, cryo-sample testing stage, and fs-laser system) for the instrument protocol development and sample analysis. The targeted analog samples could be from a wide range (various minerals, complex organic biosignatures, organics spiked minerals, natural collected terrestrial analogs, and beyond), and the research goal should match the science objectives of NASA’s current and future missions, such as method development analyzing planetary surface samples.
