3.1
HST observations can be requested with a General Observer (GO; Section 3.2) or a Snapshot (SNAP; Section 3.3) Proposal. A GO Proposal can be Small (Section 3.2.1), Medium (Section 3.2.2), Large (Section 3.2.3), Calibration (Section 3.2.4), Long-Term (Section 3.2.5), or Treasury (Section 3.2.6). Funding for projects that do not require new HST observations can be requested with an Archival Research (AR; Section 3.4) Proposal. An AR Proposal can be either a Regular AR (Section 3.4.1), a Legacy AR (Section 3.4.2), or a Theory (Section 3.4.4) Proposal. Proposals can request observing time on Chandra (Section 3.5), Spitzer (Section 3.6), XMM-Newton (Section 3.7), NOAO telescopes (Section 3.8), and NRAO facilities (see Section 3.9) in conjunction with requests for HST observations. Mid-cycle proposals (see Section 3.10) may be submitted at any time between August 15, 2016 and January 31, 2017; proposals submitted after February 1, 2017 will be held over for the regular Cycle 25 TAC review. At any time scientists can request Director’s Discretionary (DD) time for unanticipated and scientifically compelling astronomical observations (Section 3.11).
