Hubble Space Telescope Call for Proposals
for Cycle 16

Policies, Procedures &
Phase I Proposal Instructions

Call for Proposals

We invite scientists to participate in Cycle 16 of the Hubble Space Telescope (HST). The telescope and its instruments were built under the auspices of the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA). Management of HST's scientific program is carried out by the Space Telescope Science Institute (STScI). We anticipate allocating up to 3000 orbits in Cycle 16, including up to 1000 orbits for Large and Treasury proposals, with the remainder allocated to regular GO Programs. An additional 500-800 SNAPSHOT targets may also be allocated. Abstracts of previously accepted programs can be found on the HST proposal catalogs Web page, listed in Appendix D.
