Approved Guest Investigator programs

This page details the programs for execution by TESS as part of the Guest Investigator program.

The target lists are posted on this page as soon as the team has prepared the final target list for upload to the spacecraft, which happens 1-2 weeks before the start of a sector.

You can click on the title of each program to read a summary of the research objectives.

Cycle 1

Cycle 1 contains all targets proposed through the Guest Investigator program for the first year of the TESS mission. All programs are to observe sources in the Southern Ecliptic hemisphere.
