Applicant types: Others (see text field entitled "Additional Information on Eligibility" for clarification)
Proposers must be affiliated with an institution at nspires.nasaprs.com/ and, in general, NASA provides funding only to U.S. institutions. Organizations outside the U.S. that propose on the basis of a policy of no-exchange-of-funds; consult the NASA Grant and Cooperative Agreement Manual (GCAM) (https://www.nasa.gov/grants-policy-and-compliance-team/#Regulations) for specific details. Some NRAs may be issued jointly with a non-U.S. organization, e.g., those concerning guest observing programs for jointly sponsored space science programs, that will contain additional special guidelines for non-U.S. participants. Also reference the GCAM for special instructions for proposals from non-U.S. organizations that involve U.S. personnel for whom NASA support is requested.
