Leocast Space LLC

Leocast Space LLC, a Colorado-based sole proprietorship operating as a limited liability company, provides atmospheric and space-weather research services to NASA as a prime recipient under federal research grants and SBIR Phase I contracts, competing under small-business set-asides and civilian space research designations. The vendor has no subcontract footprint and operates exclusively as a prime on a single customer relationship.

Leocast's recent work centers on thermospheric data assimilation and satellite orbital-decay forecasting. Under a $223,468 small-business set-aside SBIR Phase I definitive contract awarded September 30, 2026, by NASA's Shared Services Center, Leocast is transitioning physics-based thermospheric data assimilation methodologies to improve drag forecasting for low Earth orbit satellites, with place of performance in Longmont, Colorado and completion scheduled for March 30, 2027. In parallel, Leocast received a $30,001 research grant from NASA on September 1, 2025 (completion August 31, 2026) to develop software for processing Starlink orbital decay data and inferring orbit-effective neutral densities; this effort supports NASA's Goddard Space Flight Center Satellite Tracking and Communications division's broader mission to enhance atmospheric modeling and space weather forecasting using commercial satellite tracking data. A third award in the source, also referenced as a grant, carries identical dates and funding to the Starlink orbital decay software work.

Leocast's customer concentration is absolute — all three awards are from NASA's Shared Services Center, representing the full $253 thousand in combined potential value. Activity is minimal: two awards in 2025, one in 2026. The vendor faces one recompete opportunity within the next twenty-four months — the $223 thousand SBIR Phase I contract completes March 30, 2027. No parent vehicles, subcontract relationships, or multi-agency exposure appear in the footprint. Capability framing derives from SBIR and atmospheric-research grant work rather than from commercial service delivery or broader federal contracts.
