The Mars Exploration Directorate at the JPL is sponsoring a study to examine technical feasibility of developing small spacecraft missions (SSc) capable of low-cost compelling science. Low cost small spacecraft missions can enable unique mission concepts with higher than normal mission risk. This increase in risk can create opportunities for low-cost, compelling science missions in regions that may be otherwise unexplored, provide opportunities for constellations, networks scouts, and fundamentally new measurements. Potential science instruments for MEPAG high-priority investigations suited to small spacecraft mass, volume, power, and cost constraints include compact versions of a camera (MSL EECam), Meteorology (MEDA-ATS or FMI wind, barometry, T, and P), Seismometer (INSIGHT SEIS), Atmosphere and trace Gases (MSL Tunable Laser Spectrometer), Dust (ExoMars MicroMED) analyzers, and fluxgate magnetometers (INSIGHT Mag). Two examples of low cost mission concepts are LOKI (Localizing Organic Key Ingredients), an areostationary SmallSat orbital constellation designed to measure trace gases, and TH2OR, a time-domain EM sound capable of water detection to a depth of many kilometers which would be landed via a small high impact energy device (SHIELD).
