NASA and the Space Telescope Science Institute (STScI) are pleased to announce the Cycle 26 call for proposals for Hubble Space Telescope (HST) observations and funding for archival research and theoretical research programs. Participation in this program is open to all categories of organizations, both domestic and foreign, including educational institutions, for-profit and nonprofit organizations, NASA centers, and other government agencies.

This solicitation for proposals will be open through 8:00 pm EDT on 17 August 2018. The Astronomer's Proposal Tool (APT), which is required for Phase I proposal submission, will be made available for Cycle 26 Phase I use on 14 May. Results of the selection will be announced by the end of October 2018.

All programmatic and technical information, as well as specific guidelines for proposal preparation, are available electronically from the STScI announcement webpage.

Please take note of the What's New for Cycle 26 section on the announcement page.

In particular, the Director has decided to implement an anonymous review process for Cycle 26. This follows recommendations by a working group and discussion with the Space Telescope Users Committee (presentation). The decision has been endorsed by the STUC, the Space Telescope Institute Council and the AURA Board, and is supported by NASA. A description of the process and instructions on how to adjust proposals to comply with the new requirements are included in the Call for Proposals.

Questions can be addressed by email to the STScI Help Desk or by telephone to +1 410-338-1082.
