The Planetary Science and Technology from Analog Research (PSTAR) program addresses the need for integrated interdisciplinary field experiments as an integral part of preparation for planned human and robotic missions. Furthermore, the program solicits proposals for investigations focused on exploring the Earth’s extreme environments in order to develop a sound technical and scientific basis to conduct astrobiological research on other solar system bodies. The focus of this program element is on providing high-fidelity scientific investigations, scientific input, and science operations constraints in the context of planetary field campaigns.

The PSTAR solicitation is a consolidation of two previous calls: Astrobiology Science and Technology for Exploring Planets (ASTEP) and Moon Mars Analogue and Mission Activities (MMAMA).

From 2001 – 2014, ASTEP supported investigations focused on exploring Earth’s extreme environments to learn how best to search for life on other planets.
