About the company
Nathan Stone, doing business as Stone Umbrella Consulting, is a sole proprietorship based in Gray, Maine, that operates exclusively as a subrecipient on federal research grants. The vendor has no prime contract or grant awards and holds no seat on government-wide acquisition vehicles.
Stone Umbrella's entire recent footprint consists of three sub-awards issued between February and September 2024, totaling $223 thousand in combined obligated dollars. All three sub-awards flow from the National Aeronautics and Space Administration, channeled through the University of Arizona as prime grantee. The work centers on support for the CheMin mineralogical instrument aboard the Mars Science Laboratory (MSL) mission, specifically experiment planning, data analysis, and mission operations during Phase II and Phase V of the instrument's operational lifecycle. Two of the three sub-awards (issued in February and June 2024) carry the same scope description and trace to a successor cooperative agreement to NNX17AK78A; the third (issued in September 2024) designates itself as Phase V work under the same mission framework.
Stone Umbrella's role is narrowly specialized and institution-dependent: the vendor serves as a technical sub-recipient to the University of Arizona's NASA-funded planetary science research program rather than as a federal prime or indirect customer of any agency. There is no evidence in the source of contract-vehicle participation, recompete exposure within the next twenty-four months, or expansion into civilian or defense prime contracting. Activity is confined to the single fiscal year 2024, with no awards before February 2024 appearing in the source data.
