About
Apex Space is a spacecraft manufacturer founded in 2022 that produces productized, configurable satellite bus platforms ranging from 100 to 500 kilograms, designed for rapid delivery and scalability to serve the growing demand for commercial and government space missions. Unlike traditional satellite manufacturers that build fully custom spacecraft for each customer, Apex offers standardized bus platforms that dramatically reduce lead times and per-unit costs, enabling customers to deploy constellations at production scale.
SAR Satellite Intelligence & Earth Observation
Capella Space is the leading commercial SAR satellite imagery provider with 0.25m resolution, all-weather day/night collection; acquired by IonQ in May 2025 to build space-based quantum networks.
About
Capella Space is the leading commercial provider of Synthetic Aperture Radar (SAR) satellite imagery, offering high-resolution earth observation data that is entirely independent of weather conditions, cloud cover, or lighting. Unlike optical satellites that require clear skies and sunlight, Capella's SAR constellation uses radar pulses to image the earth's surface at any time of day or night — making it uniquely valuable for time-sensitive applications in defense, disaster response, maritime monitoring, and infrastructure surveillance. The company's Acadia-class satellites achieve spotlight-mode resolution down to 0.25 meters, among the highest available from commercial SAR systems.
