Welcome to the web pages for scientists and engineers who plan to propose or have submitted a proposal to a research solicitation from the Science Mission Directorate. The researcher’s section is for scientists and engineers who plan to propose or have submitted a proposal to one of our research solicitations. The section includes various aspects of solicitation, submission, and peer review of proposals to the Science Mission Directorate. Points of contact by program and subject area are provided at the Program Officers List, and some selection statistics are available on our Grant Stats page. Those are our most popular pages within this research section of the web site. Links to other pages can be found in the navigation list to the right of this page.

NEW! If you are looking for the research opportunities for the NASA post doctoral program, or information about the transition of the program from ORAU to USRA please go to

NASA Science research and analysis (R&A) is composed of projects being conducted by scientists, engineers, and educators from NASA centers, universities, nonprofits, other Government laboratories, and for profit corporations all across the U.S. NASA Science solicits proposals for projects covering a very wide range of subjects and evaluates submissions by peer review.  Learn more about what opportunities exist, what projects were funded recently, or what fellowship programs are available.

 A full description of calls for proposals can all be found in the SMD omnibus solicitation called Research Opportunities in Space and Earth Science (ROSES). ROSES, other solicitations, and community announcements are available on the solicitations page, including an RSS feed for the latest clarifications, corrections, and amendments to ROSES. Additionally, there are regular progress updates in the form of a letter from SARA.

Research program specific questions should be directed to the relevant program officer on the program officers list. However, if your question is of a more general nature or remains unresolved, please contact SARA.

To simplify the process for proposers, there is a "how to" guide  and useful links found in the library. Early career researchers are encouraged to volunteer to serve as a reviewer, either using the volunteer reviewer web forms or by sending an email to SARA.
