Release Notice: January 13, 2016
NASA and The Space Telescope Science Institute (STScI) are pleased to announce the Cycle 24 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, profit and nonprofit organizations, NASA Centers, and other Government agencies.
Cycle 24 will extend from October 1, 2016 to September 30, 2017. We will accept proposals for the following instruments: ACS, COS, FGS, STIS, and WFC3.
This solicitation for proposals will be open through April 08, 2016 8:00pm EDT. The Astronomer's Proposal Tools (APT), which is required for Phase I Proposal Submission will be made available/released for Cycle 24 Phase I use during the 2nd week of February 2016. Results of the selection will be announced by the end of June 2016.
Questions can be addressed to the STScI Help Desk (email: email@example.com; phone: 410-338-1082).

HST Phase I Roadmap
Up to 10% of the available HST observing time may be reserved for Director's Discretionary (DD) allocation.
Up to 200 orbits per cycle will be available for Mid-Cycle GO programs. Mid-Cycle programs were initiated in Cycle 23 to provide the community with an opportunity to propose for in-cycle observations of recently-discovered, non-variable objects. As such, they complement Director’s Discretionary programs, which target unexpected transient phenomena and time-critical observations..
