About Capella, an IonQ company

Capella, an IonQ company, builds trusted space systems that deliver secure, rapid, and actionable Earth intelligence to amplify decision-making for allied partners. As the first U.S. company to launch and operate a commercial Synthetic Aperture Radar (SAR) constellation, Capella provides precise, high-resolution radar imagery in any condition—day or night, through clouds, smoke, and darkness. Capella is defining the future of space-based intelligence through a vertically integrated approach that spans spacecraft design, advanced radar payloads, manufacturing, automated tasking, and low-latency delivery of mission-ready data. Capella designs for the realities of modern defense and intelligence: speed, sovereignty, and resilience. Powered by IonQ, Capella is creating the world’s first quantum-enabled Earth observation network—transforming how intelligence is delivered through innovation, speed, and trust. This next-generation architecture will provide governments and global partners with a decisive edge: the ability to see, decide, and act with confidence in any environment.
