Amendment 31: TESS Phase-1 proposal due date delay

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.

To give more time to proposers who are without power because of Hurricane Irma, this amendment delays the Phase-1 proposal due date for this program element to October 6, 2017. Phase-1 proposals are due by 4:30 PM Eastern time via the ARK/RPS web page (see subsection 2.2.1).

Technical questions concerning this program element may be directed to Patricia Boyd, who may be reached at
