# NSF logs $283M across eight awards on Aug. 28, led by $145M Caltech LIGO grant

Federal awards data shows the National Science Foundation obligated funds to universities, nonprofits and research centers in a single day's postings.

The National Science Foundation obligated $145M to California Institute of Technology under award 2309200 on Aug. 28, the largest single posting in an eight-award batch that totaled, by this paper's arithmetic, roughly $283M recorded that day on USASpending.gov.[^7]

That Caltech cooperative agreement covers LIGO laboratory operations and maintenance through 2028. Federal awards data shows the figure has moved twice since it was first observed at $133M, reaching $145M at the latest revision. Outlays against the award stand at $111M.

Five of the eight awards carried upward revisions from their prior values. The second-largest posting was $38.1M to Computing Research Association Inc. under award 2313998, for a computing and information science graduate fellowship program; outlays there are $16M.[^6] Rocky Mountain Innovation Initiative Inc. received $30.5M under award 2315760 for a Colorado-Wyoming climate resilience cooperative agreement, up from $30M across three revisions.[^4] National Collegiate Inventors & Innovators Alliance, Inc. drew $29.2M under award 2320948, up from $24.8M across two revisions, with $17.4M in outlays to date.[^2]

Arizona State University received $18M under award 2315479 for a Southwest sustainability innovation engine cooperative agreement, up from $15M across two revisions.[^5] University of Tennessee received $11.7M under award 2309083 for its Center for Advanced Materials & Manufacturing, up from $8.7M across two revisions, with $6.92M in outlays.[^8]

The University of Chicago received $10.7M under award 2317138 for a physics frontier center cooperative agreement, with $6.19M in outlays to date.[^3] University of Texas at Austin received $5.21M under award 2322664, a project grant for Arctic coastal ecosystem research; outlays stand at $2.61M.[^1]

The read here is that the Aug. 28 batch is weighted toward multi-revision cooperative agreements rather than first-time obligations. Six of the eight awards are cooperative agreements, and five show at least two prior observed values, suggesting these are incremental funding steps on existing instruments rather than new starts.

On Aug. 27, Congress.gov recorded the referral of HR10173 to the House Committee on Science, Space, and Technology. The bill would reauthorize the research experiences for undergraduates program at the National Science Foundation.[^9] The referral is a legislative step separate from the Aug. 28 obligations; the facts carry no stated connection between the bill and the awards posted that day.
