Amendment 30: Changes to text and the due date for program element D.11 TESS Guest Investigator Cycle 2

The TESS Guest Investigator (GI) Program solicits proposals for the acquisition and analysis of scientific data from the Transiting Exoplanet Survey Satellite (TESS) mission, a NASA Explorer mission that launched in April 2018 and began regular science operations in July 2018. Observations associated with the TESS Guest Investigator (GI) Cycle 2 solicitation will be collected during the second year of operations during which the spacecraft will survey the northern ecliptic hemisphere. Proposals submitted to this program should be for new science investigations of the northern ecliptic hemisphere and outside the TESS core science program.

This Amendment delays the due date for Phase-1 proposals to February 28, 2019 (at 4:30 pm Eastern time via and makes a number of changes throughout the text, most significantly in Section 2.2.1. Other changes include presenting revised versions of the TESS Input Catalog and Candidate Target List in Section 1.2.2, the Web TESS Viewing Tool in Section 2.3, and the planning start date in Section 3. In all of these cases new text is in bold and deleted text is struck through. In addition, the technical point of contact has changed, see Section 3.
