By agreement with NASA HQ, the NASA Exoplanet Science Institute (NExScI) and the Space Science Telescope Institute (STScI), the JWST Telescope Allocation Committee (TAC) will award NASA Keck time to highly ranked proposals that request observations from both JWST and NASA Keck. Proposers will submit a single proposal to STScI/JWST to request time on both observatories for JWST Cycle 2 and NASA Keck semesters 2023B and 2024A. This procedure is meant to avoid having to submit separate proposals to and be approved by both the JWST and Keck TACs.
The only criterion above and beyond the usual review criteria is that both sets of data are required to meet the science goals. The proposed project does NOT need to require simultaneous JWST and Keck observations.
This joint program will start with the JWST Cycle 2 proposal solicitation with proposals due on January 27, 2023. No NASA Keck time awarded to a joint program will be scheduled prior to the start of the 2023B observing semester (August 1, 2023). Some information on the joint program is given below; read the Cycle 2 Call for Proposals and this page for complete information.
The Keck Telescopes are two 10-meter aperture telescopes and are operated for the California Association for Research in Astronomy (CARA), the University of Hawaii (UH), NASA and the California Institute of Technology by the W. M. Keck Observatory in Waimea, Hawaii.
NExScI administers NASA's portion of time on the Keck Telescopes, issuing the twice yearly proposal solicitations, conducting the peer review, and finalizing selections. If you require access to a past NASA Keck Call for Proposals, please email us at KeckCFP@ipac.caltech.edu
NASA intends the use of the Keck telescopes to be highly strategic in support of on-going missions and/or high priority, long-term science goals. The NASA Keck call is open to a wide range of disciplines spanning from exoplanets and solar system topics to galactic and extragalactic topics.
The opportunity to propose as Principal Investigators for the NASA time on the Keck Telescopes is open to all U.S.-based astronomers (i.e. those who have their principal affiliation at a U.S. institution).
Subject to availability of funds, Principal Investigators of programs awarded time will receive limited research and travel funding with the amount determined through formulaic means. Successful Target of Opportunity and twilight observing proposals do not receive financial support since the observations may never be triggered. NExScI manages the Keck PI Data Awards (KPDAs) and will contract with the Jet Propulsion Laboratory (JPL) to administer their disbursement.
Remote observing facilities (ROFs) at Caltech/IPAC (Pasadena, CA) and Yale University (New Haven, CT) are typically available for use by NASA Keck time awardees. Scientists wishing to use the ROFs should start the approval process 5 weeks in advance of their scheduled observations.
NExScI and WMKO maintain the Keck Observatory Archive (KOA), an archiving and access system for data collected with all past and present Keck instruments. All Keck data are publicly accessible following the 12-month (for NASA Keck data collected after 2023A; prior to 2023A the period of exclusive use for NASA Keck data was 18-months) or 18-month (for other Keck partner institutions) period of exclusive use.
NExScI facilitates the NASA IRTF Keck User's Group (NIKUG). The NIKUG reviews all aspects of the operations of the facility, including budgets, observing proposal review, visitor support, telescope performance, maintenance, instrumentation, operational procedures, scientific results, and future plans. The group meets twice a year and reports to NASA Headquarters. Current membership of the NASA Keck NIKUG can be found here.
This NASA Keck web site is intended for professional researchers who wish to submit proposals for the NASA allocation of observing time at the W. M. Keck Observatory. For general public information, please visit the Keck Home Page.
