NASA opens 2027 NIAC Phase I proposals ahead of October virtual forum

NASA has opened its 2027 Innovative Advanced Concepts Phase I solicitation in the United States, with initial proposals due October 28 and a virtual forum for prospective applicants set for October 7. The program funds studies of early-stage aerospace ideas; an award would support testing a concept’s feasibility, not approve a mission to fly it.

The appendix was released on September 28, according to NASA’s September 30 notice and its NSPIRES solicitation record. NASA is seeking proposals for concepts that take a substantially different approach to future human or robotic science and exploration missions. The opportunity is aimed at ideas still at an early stage of technical development.

Who can apply for NIAC Phase I

All categories of U.S. organizations may apply. NASA’s federal opportunity listing says the principal investigator and team members may be affiliated with any type of U.S. organization. Non-U.S. organizations may participate without an exchange of funds, subject to NASA’s policy on foreign participation. NASA’s event notice and the federal listing differ on whether such organizations may lead a study, so applicants should check the solicitation’s eligibility terms before relying on that point.

The application process has two stages. Eligible applicants can submit a brief Step A proposal; NASA then invites some applicants to prepare an expanded Step B proposal. Proposals must be submitted electronically through NSPIRES by an authorized representative of the proposing organization, according to the federal listing.

October forum and proposal deadlines

NASA has scheduled the virtual proposer forum for October 7, from 1 p.m. to 3 p.m. Eastern Time. The agency says it will address key aspects of the Phase I appendix. The agenda, joining information and related materials are to appear on the NSPIRES page for the opportunity; the available notice does not set out a detailed session agenda.

The federal opportunity listing asks prospective proposers to submit questions about the appendix by close of business on October 6, through NASA’s question portal or the NIAC program email. It says answers may be sent by email or added to the opportunity’s frequently asked questions document. The forum therefore falls shortly before the first proposal deadline.

Step A proposals are due October 28 at 5 p.m. Eastern Daylight Time, the NSPIRES record says. NASA’s notice targets December 8 for Step B invitations. For those invited to continue, Step B proposals are due January 13, 2027, at 5 p.m. Eastern Standard Time, according to NSPIRES.

NASA anticipates notifying applicants of selections in April 2027 and targets July 2027 for awards. Those are forward-looking dates in the agency’s notice, not results: the available records do not identify selected 2027 projects. Applicants can use the schedule to plan, while treating the notification and award dates as targets.

What a Phase I award would fund

NASA describes the proposed work as an early-stage feasibility study. The federal listing says a Phase I award typically supports a nine-month effort to examine whether a visionary concept is viable. NASA’s current notice estimates 12 to 16 awards, with a typical award amount not exceeding $225,000. The federal grants listing presents the same $225,000 maximum and gives 16 as the expected number of awards.

Those figures concern the newly opened opportunity. For comparison, NASA said it made 18 Phase I awards in 2026, totaling $3.2 million, with up to $175,000 per award for a nine-month initial investigation. The earlier award amounts and count should not be read as outcomes of the 2027 solicitation.

NASA has described NIAC projects as early concept development rather than official agency missions. A Phase I study can examine an idea’s technical promise, but the present solicitation does not establish that any proposed vehicle, instrument or mission will be built. That distinction matters when judging the program’s ambitious descriptions against what a nine-month feasibility study can establish.

A previous NIAC concept shows the limits of a study

One independently reported example is SPARK, a proposal for small flying robots that might explore caves on Saturn’s moon Titan. In August, Space.com reported that researcher Daniel Drew of the University of Hawaii at Mānoa was beginning a nine-month NIAC Phase I study of the concept. Drew told the publication that further study would be needed and that its timing relative to NASA’s Dragonfly mission was uncertain.

Drew also told Space.com that the proposed electric propulsion system had a substantial efficiency limitation for widespread use on Earth, despite possible specialized applications. His assessment concerns SPARK’s technology, not NIAC proposals generally. It illustrates why a Phase I award is a chance to investigate obstacles as well as possibilities, rather than evidence that a future mission is ready.

For prospective 2027 applicants, the immediate decisions are whether their concept fits the early-stage call, whether their organization meets the eligibility and registration requirements, and whether they can meet the October 28 Step A deadline. NASA’s forum and the NSPIRES solicitation page are the places the agency identifies for further instructions and updates as the process moves toward invited Step B proposals.
