• The TESS - Cycle 4 program is NOT soliciting new proposals. Only those Principal Investigators who have been accepted for observations and who have received a request for budget information should submit a cover page in accordance with the instructions in that letter. No other submissions will be considered.
• NOTICE: Amended October 23, 2020. In addition to small changes throughout, the following substantive edits were made: 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.
• The description of the specific proposal opportunity on this page is contained in the document 'D.10 TESS Guest Investigator Cycle 4'. The document 'D.1 Astrophysics Research Program Overview' describes research activities within the NASA science division that is managing the specific proposal opportunity on this page and may impose requirements upon proposals submitted to this program element. The document 'Summary of Solicitation' describes the common requirements for all ROSES-2020 proposal opportunities. The documents 'Table 2' and 'Table 3' contain the list of all proposal opportunities and their due dates, sorted by due date or appendix number, respectively. All of these documents are kept up to date and incorporate amendments, clarifications, and corrections in a clearly identifiable manner.
