Astra has developed one of the world’s most responsive and affordable orbital launch systems. Rocket 3.3 is an expendable, vertically-launched two stage LOX/kerosene rocket, designed to fit inside a standard shipping container and built to dramatically lower the cost of access to space. Eschewing labor-intensive processes such as carbon composite layups, Astra has focused on proven and cost-efficient metallic structures.
Rocket 3.3 consists of a first stage powered by five electric-pump-fed engines and an upper stage propelled by a single pressure-fed Aether engine.
