ROSES-16 Amendment 7: New text regarding Ocean Worlds has been added to C.12 PICASSO, C.13 MatISSE, and C.14 PSTAR The Planetary Instrument Concepts for the Advancement of Solar System Observations (PICASSO) and Maturation of Instruments for Solar System Exploration (MatISSE) Programs support the development of spacecraft-based instruments. Amendment 7 adds text to those program elements noting that instruments focused on the detection of extant life in the "Ocean Worlds" of the outer Solar System are especially of interest and will be considered for separate funding from the Outer Planets and Ocean Worlds Program. Planetary Science and Technology Through Analog Research (PSTAR) program 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. Amendment 7 adds text to PSTAR noting that science operations and technology focused on the detection of extant life in the "Ocean Worlds" of the outer Solar System are especially of interest and will be considered for separate funding from the Outer Planets and Ocean Worlds Program. The due dates for MatISSE, only, have changed. MatISSE Step-1 proposals are now due by May 20, 2016, and MatISSE Step-2 proposals are now due by July 21, 2016. The due dates for PSTAR and PICASSO have not changed. On or about April 15, 2016, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2016" (NNH16ZDA001N) will be posted on the NASA research opportunity homepage at http://nspires.nasaprs.com/ and will appear on the RSS feed at: http://nasascience.nasa.gov/researchers/sara/grant-solicitations/roses-2016. Questions concerning program element C.12 PICASSO may be directed to: James Gaier at james.r.gaier@nasa.gov. Questions concerning program element C.13 MatISSE may be directed to: William B. Cook at william.b.cook@nasa.gov. Questions concerning program element C.14 PSTAR may be directed to either Sarah Noble at sarah.noble-1@nasa.gov or Mary Voytek at mary.voytek-1@nasa.gov.
