Open Cosmos

Open Cosmos is a UK space company providing end-to-end satellite mission services — from spacecraft design and manufacturing through launch integration and on-orbit operations. Founded in 2015 and headquartered in Didcot, Oxfordshire, the company builds standardized small satellites (20-200 kg class) on rapid timelines and operates them on behalf of customers, covering Earth observation, IoT connectivity, and technology demonstration missions. Open Cosmos serves government space agencies seeking sovereign satellite capability (including a national constellation for Algeria, ALSAT-1N), commercial operators, and research institutions.

The company's business model is particularly attractive to emerging space nations that want an operational satellite without building a full internal space program. Open Cosmos received ESA and UK Space Agency contracts and Series B funding from investors including Seraphim Space Capital.
