For the second fiscal year in a row, NASA awarded ~20% fewer grants than the recent historical average. That's about 500 fewer grants going out to scientists around the country.
Line chart showing the running sum of new grant awards in FY 2026 compared to the average between 2021-2025, which is about 20% higher.
