Aspect Aerospace has $2.4 million and twelve months to build a satellite the size of a circuit board and prove it can measure ionospheric plasma from very low Earth orbit without burning up.
The funding: a $1.9 million Space Force SBIR to build a space-ready Single-Board Satellite prototype, and $500,000 from SOSV. Aspect is a University of South Alabama spin-out. The CEO and founder, Drew Russ, spent eight years at Aerospace Corporation before spinning out. The prototype is due in 18 months.
The problem the company is trying to solve is real. VLEO — below 450 kilometers — is operationally important and physically punishing. Atmospheric drag at that altitude is significant enough that conventional spacecraft burn down faster and operators routinely deal with plasma drag affecting radio signals. Aspect's thesis is that existing plasma measurement from radio occultation is too coarse to be useful, and a constellation of sub-cubesat sensors could map plasma in three dimensions at sub-meter resolution.
The measurement method is the core claim. Existing systems primarily use radio occultation: a signal passes through the ionosphere and gets refracted by plasma along a multi-hundred-kilometer path, producing a single aggregated measurement. Russ described it this way: it sums plasma over a path and provides no insight into distribution. His company uses a time-domain impedance probe, or TDIP, which takes near-instantaneous point measurements at a single location. The difference is the same as comparing a single average temperature for an entire city against readings at every building in it. TDIP gives point measurements; radio occultation gives path averages. Those are different data types, not necessarily better ones. Aspect's claim that high-fidelity data is a game-changer for satellite operators is a CEO claim. The Naval Research Laboratory confirmed the measurement capability independently, which is different from validating that the measurement improves operational outcomes.
The VLEO environment is not speculative. Jagsat-1, a 2U cubesat built by Russ and collaborators and deployed from the ISS in 2022, operated at the low end of LEO and confirmed the space weather sensor before deorbiting. That is a real flight result. The SBIR scope targets the integration of sensing, communications, and power onto a single PCB, with units designed to last roughly six months before orbital decay.
The broader context for VLEO investment is not limited to one startup. The European Defence Agency committed 15.65 million euros in March 2026 to VLEO-DEF, a program to develop the first European military VLEO satellite concept. ESA separately funded a 2.3 million euro demonstrator satellite for VLEO with Thales Alenia Space as prime contractor and QinetiQ as a study partner on the Skimsat Phase A/B1 study. The VLEO satellite market is projected to grow from $10.4 million in 2024 to $1,502.5 million by 2034, according to BIS Research.
Whether Aspect's architecture scales from a 2U cubesat demo to a functional 100-unit swarm in VLEO is an open question. The six-month operational life is designed into the approach (short enough to avoid the worst drag accumulation but also short enough that a constellation would need constant replenishment). The $2.4 million gets the prototype built. Whether it flies, and whether the data is worth buying, are separate questions that the funding does not answer.
