## Who can apply

- 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.

An individual may be Principal Investigator (PI) of one and only one proposal to this program element. There is an exception for multiple submissions per PI only when institutions require oversight for efforts that involve Science PIs. The rules regarding interagency awards described in Section 1.1.1 of B.1 Heliophysics Research Program Overview and Section 7 apply to this program element. Proposals submitted to this program will be evaluated using a dual-anonymous review process.
