Important Notices

STScI will electronically notify Program Admin PIs and their institutions of Cycle 23 approved amounts for programs (Mid-Cycle, Director’s Discretionary, Chandra, and Spitzer) reviewed at the 1st Interim FRC meeting held in March 2016. The expected date of notification is ~ April 4, 2016. In cases where program amounts are reduced, the Program Admin PI is responsible for notifying each Co-I of the amount to submit for their revised budget.

GO awards are issued within 30 days after the first successful observations.

All grants are awarded subject to the submission of any overdue reports and/or the submission of revised budgets as required.

In accordance with General Grant Provisions (8/06) Section IX (A), pre-award costs are allowable. Please note that such costs are incurred at the grantee’s own risk and will not impose an obligation on the part of STScI or NASA if an award is not subsequently made, or if an award is made for a lesser amount than the grantee anticipated.


On January 13, 2016, the Cycle 24 Call for Proposals for Hubble Space Telescope (HST) Observations and funding for Archival Research and Theoretical Research programs was released.
