The REXUS vehicle is an unguided spin-stabilised solid propellant single-stage rocket. It is composed of an Improved Orion motor with exhaust nozzle extension, a tailcan, three stabilizing fins, a motor adapter with an integrated separation system and the payload. The standard configuration of this payload comprises the recovery module, the service system, an ejectable nosecone and experiment modules. The total mass of the rocket is around 515 kg comprising a propellant mass of 290 kg, motor and vehicle hardware of around 125 kg and a payload mass of around 100 kg. The total rocket vehicle has a length of approximately 5.6 m depending on the size of the experiments and the diameter is 356 mm. The mass of each experiment module structure and bulkhead is approximately 5 kg. The total available mass for the student experiments is about 30 kg.

This rocket gives approximately three minutes of spaceflight. For reduced microgravity conditions a de-spinning option is provided. The payload returns by a parachute system for recovery.
