Orbital Arc

Orbital Arc is a Houston-based deep-tech spacecraft propulsion startup founded in 2023 by Jonathan Huffman, building Gas-Phase Field Effect Electric Propulsion (Gas FEEP) thrusters and the RIOT Drive (Relativistic Ion Thrust Drive) for satellites and in-space transportation. Its ultra-lightweight electric thrusters use solid naphthalene fuel that sublimates at room temperature instead of noble gases, targeting high specific impulse for satellite constellations. Backed by Techstars and Capital Factory, the company completed a sub-scale physics demonstration at Oak Ridge National Laboratory (TRL 3). This is a hardware company with no public API, SDK, or developer surface as of this enrichment pass.

Orbital Arc is profiled on the APIs.io network. Tagged areas include Company, Space, Aerospace, Electric Propulsion, and Satellites.

Orbital Arc’s developer surface includes engineering blog, support, and 2 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/orbital-arc: open an issue to ask a question, or submit a pull request to add artifacts.
