Preparing for the 2020 U.S. Decadal Survey • NASA will support studies of 3-4 missions in the $1-2B range • The initial short list of candidates (Paul Hertz, January 2015 AAS): – FAR IR Surveyor–The Astrophysics Visionary Roadmap identifies a Far IR Surveyor as contributing through improvements in sensitivity, spectroscopy, and angular resolution. – Habitable-Exoplanet Imaging Mission–The 2010 Decadal Survey recommends that a habitable-exoplanet imaging mission be studied in time for consideration by the 2020 decadal survey. – UV/Optical/IR Surveyor–The Astrophysics Visionary Roadmap identifies a UV/Optical/IR Surveyor as contributing through improvements in sensitivity, spectroscopy, high contrast imaging, astrometry, angular resolution and/or wavelength coverage. The 2010 Decadal Survey recommends that NASA prepare for a UV mission to be considered by the 2020 Decadal Survey. – X-ray Surveyor – The Astrophysics Visionary Roadmap identifies an X-ray Surveyor as contributing through improvements in sensitivity, spectroscopy, and angular resolution. • N.B. – ESA’s Athena
