NASA Innovative Advanced Concepts (NIAC) is a NASA program that funds early-stage studies of visionary ideas that could transform future NASA missions. It runs in three phases: a nine-month Phase I feasibility study, a two-year Phase II study that needs a development roadmap, and a Phase III study meant to transition the strongest concepts. Award sizes and counts below are as described on NASA’s official pages on 2026-10-29, and NASA marks them as planned or tentative.
For a grants office, the useful way to read NIAC is as a feasibility program, not a mission-funding program. It pays for a study of whether a concept could work and where it might fit, and each later phase has to be earned from the one before. This guide sets out the three tiers side by side, the application path through NSPIRES, and the mistakes that follow from reading old press coverage instead of the current solicitation.

Suggested question: “What is NASA NIAC?”
What NIAC is and who runs it
NASA describes NIAC as a program that “nurtures visionary ideas that could transform future NASA missions.” It sits within NASA’s Space Technology Mission Directorate (STMD), as described on the official NIAC page on 2026-10-29. The program page links to the list of funded studies, the application page and a key-dates page.
NIAC is an idea-stage program. The applicant is expected to explain why NASA needs the concept and to place it within a specific aerospace architecture, mission or system, rather than a general technology line.
Eligibility
NASA’s “Work with us” page says that “researchers across government, industry and academia with high impact ideas should consider submitting a proposal.” It also states that eligible recipients of Phase I awards can propose for a follow-on Phase II study. That is the full eligibility statement on the program page as described on 2026-10-29.
Detailed eligibility criteria, such as organization types and any citizenship or location conditions, are set in each solicitation, which is posted on NSPIRES (the NASA Solicitation and Proposal Integrated Review and Evaluation System). Read the current solicitation text before committing staff time, and do not rely on a summary, including this one, for those conditions.
What NIAC funds: the three phases
The table below reproduces the figures from NASA’s “Work with us” page as described on 2026-10-29. NASA labels the amounts and award counts as planned or tentative, so they can change from one solicitation to the next.
| Phase | Funding and length | Planned awards per year | Purpose as described by NASA |
|---|---|---|---|
| Phase I | $225,000 for a nine-month study | 12 to 18 | Assess the viability of the concept |
| Phase II | $750,000 for a two-year study | Six to eight | Requires a development roadmap |
| Phase III | $2 million for a two-year study | One | Aims to transition the strongest concepts |
Two points matter for budgeting. First, Phase II is open to eligible Phase I recipients, so Phase I is the stated route into a follow-on Phase II. Second, NASA’s key-dates page describes Phase III as “up to one award per solicitation.”
Application steps
The steps NASA lists on its application page can be turned into a working path for a proposal team:
- Develop an innovative concept and write down why NASA needs it.
- Watch NSPIRES for the solicitation. NIAC solicitations are posted there, and the funding-opportunity text is the controlling document (see the general guide to the notice of funding opportunity and the funding opportunity announcement term).
- Follow the proposal preparation instructions closely.
- Place the concept within a specific aerospace architecture, mission or system.
- Contact the NIAC team with questions. The address given on the page is hq-niac at mail.nasa.gov (written here as text, not as a link).
NSPIRES is also the system used for other NASA opportunities. The NASA FINESST guide covers its application mechanics for graduate students, and the guide to funding opportunity databases shows where else such notices are indexed.
Typical timeline phases
NIAC runs on a solicitation cycle, not a rolling intake. As described on NASA’s key-dates page on 2026-10-29, the Phase I solicitation is released annually with the schedule under review, the Phase II schedule is also under review, and Phase III has up to one award per solicitation. Because the schedule is described as under review, plan around the phases below and take actual dates only from the current solicitation:
- Concept development. Done before the solicitation opens: define the concept and the architecture it would serve.
- Solicitation release. The announcement appears on NSPIRES with the proposal preparation instructions.
- Proposal preparation and submission. The longest phase for a grants office, since institutional routing runs in parallel.
- Selection. NASA announces selections after the review of proposals.
- Phase I study (nine months). Feasibility work on the concept.
- Phase II proposal and study (two years). Open to eligible Phase I recipients and built around a development roadmap.
- Phase III (two years). For the strongest concepts, with at most one award per year planned.
Common mistakes
- Proposing a technology without a mission context. NASA’s steps say to place the concept within a specific aerospace architecture, mission or system.
- Budgeting from secondhand figures. NASA labels the award sizes as tentative. Take amounts from the current solicitation, not from news coverage or from the table above.
- Assuming a fixed calendar. NASA describes the schedule as under review, so a date seen in last year’s cycle is not a plan.
- Treating NIAC as development funding. Phase I is a nine-month viability study. Phase II is open to eligible Phase I recipients.
- Skipping the roadmap for Phase II. NASA lists a development roadmap as a requirement for Phase II.
- Using an unsupported eligibility reading. The program page names researchers across government, industry and academia. Anything narrower or wider has to come from the solicitation.
