Copenhagen Suborbitals posts a video about their Sapphire rocket project. From the video caption:

Copenhagen Suborbitals is just weeks away from our first actively guided rocket flight. The Sapphire rocket has a liftoff mass of 200 kg, and stands six meters tall. Its nitrous oxide / polyurethane HATV type hybrid, controlled by servo operated copper jet vanes in the rocket jet. These powerful motors have a flawless record.

The instrumentation and payload is now passing parachute separation tests – and the two test performed confirmed our expectations for the parachute system.

The purpose of Copenhagen Suborbitals is to launch a human into space. You can god to space with a passive stable finn only rocket – but the initial acceleration needed to stay on course is too high for humans to endure. Therefore CS must master active guidance.

The fist and last purpose of the Sapphire mission is to test active guidance.

Copenhagen Suborbitals as begun making hydrogen peroxide (see earlier post with video), which they will use to test the turbo pump for their liquid fuel engine: DIY Rocket Grade Hydrogen Peroxide – Wired Science/Wired.com

Turbo pump tests were performed today with success running at app 2500 rpm as a start. Eventually this pump might be used for pressure feeding our LOX/alcohol engine.
