| ROSES-20 Amendment 42: Planetary Science and Technology Through Analog Research (PSTAR) Not Solicited this Year Planetary Science and Technology Through Analog Research (PSTAR) solicits proposals for investigations focused on exploring the relevant environments on Earth in order to develop a sound technical and scientific basis to conduct planetary research on other Solar System bodies. The PSTAR program is a science-driven exploration program that is expected to result in new science and operational/technological capabilities to enable the next generation of planetary exploration. PSTAR is converting to a biennial program and will not be solicited as part of ROSES-20. It will be solicited in ROSES-21 and every other year thereafter. This Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2020” (NNH20ZDA001N) will be posted on the NASA research opportunity homepage and will appear on SARA’s ROSES blog.
