NASA ACO Informational Webinar
August 6 @ 12:00 pm – 1:00 pm MDT
Interested in collaborating with NASA subject matter experts or accessing NASA facilities? The five-year standing ACO solicitation, which NASA announced on July 30, allows participants to enter into Unfunded Space Act Agreements for access to NASA’s aeronautics and space resources — including facilities, technical expertise, hardware, NASA technology and software — on a no-exchange-of-funds basis.
Flight tests with commercial providers may also be considered as part of the proposed work, with suborbital and hosted orbital flights to be provided through NASA’s Flight Opportunities program via a separate Space Act Agreement.
NASA intends to issue appendices every six to 12 months to address evolving space technology needs. The 2025 ACO Appendix A is open for proposals until Sept. 24.
An information webinar will be held on Wednesday, August 6 from 11am–12pm PT:
