Release Notice: January 06, 2014
NASA and The Space Telescope Science Institute (STScI) are pleased to announce the Cycle 22 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 22 will extend from October 1, 2014 to September 30, 2015. We will accept proposals for the following instruments: ACS, COS, FGS, STIS, and WFC3.
This solicitation for proposals will be open through April 11, 2014 8:00pm EDT. The Astronomer's Proposal Tools (APT), which is required for Phase I Proposal Submission will be made available/released for Cycle 22 Phase I use during the 2nd week of February 2014. Results of the selection will be announced by the end of June 2014.
Questions can be addressed to the STScI Help Desk (email: firstname.lastname@example.org; phone: 410-338-1082).

What's New for Cycle 22
- COS Lifetime Position. By the start of Cycle 22, it is expected that COS FUV spectra will have been moved from the second COS Lifetime Position (LP2) to the third (LP3) in order to ameliorate the continuing effects of gain sag. While the exact change in performance is not yet known, it is anticipated that the typical spectral resolution (λ/Δλ) may decline by about 15%. Depending on the details of the LP3 implementation, it is possible that the resolution decline for the COS FUV G140L grating may be somewhat larger.
- Joint HST-NRAO Proposals are being introduced in this cycle, allowing proposers to request time on both HST and NRAO facilities in a single proposal. For a joint HST-NRAO proposal to be successful, the project must be fundamentally of a multi-wavelength nature and must require all proposed observations to meet the science goals. Proposers should take special care to justify both the scientific and technical reasons for all observations included in their joint proposal. Proposers must always check whether appropriate archival data exist, and provide clear scientific and technical justification for any new observations of previously observed targets.
- The MAST Data Discovery Portal was released in November 2013 at http://mast.stsci.edu/explore. The Discovery Portal is a one-stop Web interface to access data from all of MAST’s supported missions, including HST, Kepler, GALEX, FUSE, IUE, EUVE, and Swift-UVOT. In addition to data at MAST, users can search for data available through the Virtual Observatory (VO), either by providing a resolvable target name or coordinate, or by using the "Search the VO" button for a given MAST data product. The VO gives Portal users access to data spanning the electromagnetic spectrum, from radio to high energy, including images, spectra, catalogs, and NASA ADS records.
- Please note the new operating system requirements for APT (due to a necessary upgrade to Java 7):
- For Mac see: http://www.stsci.edu/hst/proposing/apt/installation/osx
- For Linux see: http://www.stsci.edu/hst/proposing/apt/installation/linux.
Important Features Carried Over From Cycle 21:
- Medium Proposals are being continued as a separate proposal category. General Observer (GO) Proposals are classified as Small (1-34 orbits), Medium (35-74 orbits) or Large (75 or more orbits) based on orbit request. Medium Proposals are reviewed by the panels and ranked together with the Small Proposals. Those making the cut proceed to the TAC where a separate orbit pool of 600 orbits is available for them.
- The Ultraviolet (UV) Initiative introduced in Cycle 21 will continue in Cycle 22. This initiative is designed to take full advantage of the unique UV capabilities of Hubble while they still exist. It uses orbit allocation targets to increase the share of primary GO observing time dedicated to UV observations (central wavelengths < 3200 Angstroms). Small, Medium, Large, and Treasury GO Proposals are all eligible to benefit, as are all types of Archival proposal, but SNAP Proposals are not eligible.
The Primer provides an introductory overview of the Hubble Space Telescope and explains how to calculate the appropriate number of orbits for an observing proposal. Get the Primer as: PDF [US Letter Size], PDF [A4 Size], or as HTML.
