The Transiting Exoplanet Survey Satellite (TESS) General Investigator (GI) Program solicits proposals for the acquisition and analysis of new 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/or analysis of scientific data from ground-based telescopes are solicited. Such ground-based programs must directly support the analysis and/or interpretation of TESS scientific data.

 Phase-1 proposals are due by 4:30 pm Eastern time on March 21, 2024, via the Astrophysics Research Knowledgebase Remote Proposal System.
