Spitzer Space Telescope Cycle 10 Call for Proposals

Friday, May 3, 2013 - 18:57

On behalf of NASA and the Spitzer Space Telescope Project, the Spitzer Science Center (SSC) at Caltech is pleased to announce the release of the Cycle 10 Call for Proposals (CP). The Cycle 10 CP solicits Exploration Science (ES) General Observer, regular General Observer (GO), and Snapshot proposals. We expect to select ~7,000 hours of priority 1 and 2 programs and ~3,000 hours of priority 3 programs.


  • Exploration Science Letters of Intent Due: 31 May 2013  
  • Cycle 10 Proposal Deadline: 2 August 2013, 5:00 p.m. PDT (8:00 p.m. EDT)   

The mission is funded to operate through Cycle 10 (2014), and the Spitzer project plans to propose to the 2014 NASA Senior Review for Cycle 11 and 12 operations.

Major changes between Cycle 9 and Cycle 10 are described in Section 1.1 of the Call for Proposals.

All programmatic and technical information for Cycle 10 is available electronically from the Proposal Kit section of the Spitzer Science Center website:

Investigators worldwide from all types of institutions are eligible to submit proposals in response to this CP. Joint Hubble or Chandra observations can be proposed as part of a Spitzer Cycle 10 proposal.

All proposals must be submitted electronically using Spot, the SSC proposal planning and submission software. The S19 version of Spot is available from the SSC website and via the auto-update feature in Spot. Proposers must use this version of the software to submit their proposals and use the Cycle 10 proposal templates available at the Proposal Kit website.

Any questions should be addressed to the Spitzer Helpdesk at

Archival research proposals are not included as a part of Cycle 10 but can be funded through Research Opportunities in Space and Earth Sciences (ROSES) — 2013. The Astrophysics Data Analysis Program (ADAP), included in ROSES, supports both cryogenic and warm Spitzer archival research. For more information please see

The proposal due date for ROSES is 17 May 2013.
