NASA Request for Information: New Horizons Interstellar Mission
New Horizons Interstellar Mission

The Heliophysics Division (HPD), Astrophysics Division (APD), and Planetary Science Division (PSD) of NASA’s Science Mission Directorate (SMD) are soliciting information under this Request for Information (RFI) to determine interest in the science community for continuing the New Horizons mission operations and utilizing its unique position in the solar system to answer important questions about the heliosphere and its interaction with the interstellar medium while allowing for scientific opportunities that present themselves beyond Heliophysics.

The RFI is focused on determining whether interested science teams have a set of science objectives to propose to NASA for use of the mission beyond FY24. The purpose of this RFI is to gauge the level of interest of the wider science community in pursuing the next phase of science leadership for the mission and to estimate appropriate annual costs.

The RFI seeks responses only from United States persons, i.e., U.S. industry, universities, non-profit organizations, NASA Centers, other U.S. Government agencies, and individual researchers. International team members, i.e., entities or individuals outside the U.S., are permitted as part RFI responses from U.S.-led science teams.

This email is a partial summary of the RFI. For the full text of the RFI and response instructions, visit the NASA Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES) at and search on solicitation number NNH23ZDA011L or via the direct URL above.

All responses to this RFI must be submitted in an electronic format only via NSPIRES. Please email questions and comments concerning this RFI to the email address listed below with the subject line: “NASA NHIM Question/Clarification.”

Depending on the nature of the question(s), NASA may respond on an individual basis by email or may post questions and answers (Q&A) on the RFI’s NSPIRES landing page. Posted Q&As are intended to address inquiries of broader interest and general clarification and will be edited to preserve the anonymity of persons and institutions who submit questions. The following email address is not to be used for RFI response submissions. Any RFI submissions made via email will not be considered.
