Hubble Space Telescope Call for Proposals for Cycle 11

2.1 The Proposal Process: Phase I and Phase II

---

STScI manages the review of HST proposals and carries it out in two phases.

In Phase I, proposers submit a scientific justification and observation summary for peer review. The Review Panels and Telescope Allocation Committee (TAC) recommend a list of programs to the STScI Director for preliminary approval and implementation (see Chapter 6). This Call for Proposals focuses on Phase I policies and procedures. Separate documentation is available for Phase II.

In Phase II investigators with approved Phase I proposals must provide complete details of the observations in their proposed observing program. This allows STScI to conduct a technical feasibility review, and to schedule and obtain the actual observations. Programs are not fully approved until after submission of an acceptable Phase II program. In addition to this, Phase II investigators should do the following:

• Eligible investigators who request funding must submit detailed budgets (see Chapter 11).
• Interested, eligible investigators can submit an Education/Public Outreach (E/PO) proposal (see Chapter 10).
