The NASA Innovative Advanced Concepts (NIAC) Program supports innovative research through multiple Phases of awards. Phase I awards are typically a nine-month effort to explore the overall feasibility and viability of visionary concepts. There are two steps to the Phase I proposal process; a brief Step A proposal open to all eligible applicants, and an expanded Step B for those who are invited.
