ROSES-17 Amendment 13: TESS GI Final Text

ROSES-17 Amendment 13 releases final text for D.11 TESS Guest Investigator – Cycle 1, which replaces in its entirety the placeholder text released with the ROSES-17 NRA in February.

The TESS Guest Investigator (GI) Program solicits proposals for the acquisition and analysis of scientific data from the Transiting Exoplanet Survey Satellite (TESS) mission, a NASA Explorer mission currently scheduled for launch no later than June 2018. In a 2-year, near all-sky survey, TESS will monitor the brightness of nearby, bright F, G, K, and M stars in order to photometrically search for transiting planets smaller than Neptune. Proposals submitted to this program should be for new science investigations of the southern ecliptic hemisphere and outside the TESS core science program only. The core program consists of 1) the detection of transiting exoplanets with periods up to 10 days around stars on the pre-selected transit candidate target list (CTL; see description of CTL in Section 1.2.2), 2) the detection of transiting exoplanets with periods longer than 120 days near the ecliptic poles (optimal for JWST follow-up), and 3) assuring that the masses of fifty planets with radii less than 4 Earth radii are determined through ground-based follow-up and/or analytical techniques.

Phase-1 proposals are due by 4:30 pm Eastern time on September 29, 2017 via
