Amendment 42: This amendment releases final text and announces the final due date for program element D.10 TESS Guest Investigator Cycle 3

The Transiting Exoplanet Survey Satellite (TESS) Guest Investigator Program solicits proposals for the acquisition and analysis of scientific data from the TESS mission, a NASA Explorer mission that was launched in April 2018 and began science operations in July 2018. Additionally, proposals that support the acquisition and analysis of scientific data from ground-based telescopes are solicited. Such ground-based measurements must directly support the analysis and/or interpretation of TESS scientific data.

Phase-1 proposals for D.10 TESS Guest Investigator Cycle 3 are due by 4:30 p.m. Eastern Time on January 16, 2020 (via ARK/RPS).
