The Virginia spacecraft supplier spent 13 years turning radiation-tolerant power, batteries and computers into configurable products. Its March 2026 sale to Trident shows what happens when a small engineering shop makes the least glamorous parts of a satellite easier to buy.

Zero-Error Systems (ZES) is a Singapore deeptech semiconductor company and Nanyang Technological University spin-off that builds radiation-hardened integrated circuits, radiation-tolerant system-on-modules, and irradiation testing services. Its patented radiation-hardened-by-design technology protects low-cost commercial-off-the-shelf (COTS) electronics from radiation effects such as single-event latchup, letting satellite and space-system makers achieve space-grade power reliability and data integrity at a fraction of traditional rad-hard cost.
Astranis builds small, software-defined geostationary communications satellites - about the size of a washing machine - that deliver dedicated broadband to underserved regions and governments. Founded in 2015 in San Francisco, the company designs, manufactures and operates its MicroGEO platform entirely in-house at Historic Pier 70.
Solestial is a Tempe, Arizona space-solar company building ultrathin, radiation-hardened silicon photovoltaic modules for satellites and spacecraft. Spun out of Arizona State University research, the company makes flexible space-grade solar power modules that self-cure radiation damage at operating temperatures and targets the megawatt-class power demand of large satellite constellations and on-orbit infrastructure.
