Call for Proposals: NASA Keck Time for the 2024A Semester

Call for Proposals to Use NASA Keck Time for the 2024A Observing Semester:
Solicitation Title: 2024A NASA Keck Call for Proposals
Fiscal Year: 2023
Released: 20 July 2023

  • General Observing, Mission Support, and Key Strategic Mission Support Proposal Due Date: 14 September 2023.
  • Key Strategic Mission Support (KSMS) Notice of Intent Due Date: 16 August 2023.
  • Notice of Intent is not required for General Observer and Mission Support proposals.
  • Announcement Document: 2024A NASA Keck Call for Proposals.
  • Other Documents: Keck Instrument Availability (available in mid-August for 2024A).

The NASA Exoplanet Science Institute is soliciting proposals to use NASA’s portion of time on the two 10m Keck Telescopes for the 2024A observing semester (1 February - 31 July 2024).

In addition to General Observer and Mission Support proposals, this semester also includes a call for Key Strategic Mission Support (KSMS) proposals. KSMS proposals directly support the science goals and requirements of NASA missions and are not just larger versions of general science programs.

KSMS projects may support past, present, and/or future NASA-led missions or missions with significant NASA partnerships. Highest priority will be given to operating missions or missions approaching launch, with lower priority given to past missions (e.g., Kepler, WISE) or more distant future missions (e.g., Habitable Worlds Observatory). Required but non-binding Notices of Intent to submit a KSMS proposal are due by 16 August 2023.

The opportunity to propose as a Principal Investigator for NASA time on the Keck Telescopes is open to all U.S.-based astronomers. Investigators from institutions outside of the U.S. may participate as Co-Investigators on proposals for NASA Keck time.

NASA intends the use of the Keck telescopes to be highly strategic in support of on-going space missions and/or high priority, long-term science goals. Proposals are sought in the following discipline areas: (1) investigations in support of EXOPLANET EXPLORATION science goals and missions; (2) investigations of our own SOLAR SYSTEM; (3) investigations in support of COSMIC ORIGINS science goals and missions; and (4) investigations in support of PHYSICS OF THE COSMOS science goals and missions. Direct mission support proposals in any of these scientific areas are also encouraged.
