SIMPLEx Small Satellite Concept Finalists Target Moon, Mars and Beyond

The finalists include a 2022 robotic mission to study two asteroid systems, twin spacecraft to study the effects of energetic particles around Mars, and a lunar orbiter to study water on the Moon. At least one of these missions is expected to move to final selection and flight.
