The Transiting Exoplanet Survey Satellite (TESS) Guest 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 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.


In addition to small changes throughout, this amendment makes the following substantive changes to D.6 TESS Guest Investigator Cycle 4: A new “Mini Proposal” category is available. These programs require minimal resources, up to 50 20-second cadence targets and 1,000 2-minute cadence targets per proposal may be requested. Proposals in this category are not eligible for funding. The observing sectors were updated in Section 1.1, Section 1.3 has been updated regarding postage stamp targets, source code sharing, and joint Fermi observations, and Section 2.2 has been updated regarding overlap with proposals to the Exoplanet Research Program.


Moreover, Cycle 4 also includes the following changes from the previous cycle:


·         TESS Cycle 4 observations will be collected between June 2021 and September 2022. Due to the extended length of the cycle compared to previous cycles, the total amount of funding available to U.S.-based PIs through this solicitation is anticipated to be $3.4M, of which up to $500,000 is available to support ground-based observing programs as in Cycle 3.

·         Key Project proposals are no longer solicited.


New text is in bold and deleted text is struck through. The Phase-1 due date has been delayed: Phase-1 proposals are due by 4:30 pm Eastern Time January 22, 2021 via ARK/RPS


On or about October 23, 2020, this Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2020” (NNH20ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on SARA’s ROSES blog at:
