Copenhagen Suborbitals: Sapphire flight a success but recovery fails

Copenhagen Suborbitals launched their Sapphire rocket today from the sea off Denmark and the active guidance system successfully kept it on a straight vertical trajectory to the expected 8 km altitude. Unfortunately, on the return the parachute system did not work and the vehicle was not recovered. However, the primary goals of the test were achieved: Huge Success: Rocket flew vertically to over eight kilometers – The Engineer/ing.dk (Google Tanslate)

T minus 2 days and we are still go for launch.

Today mission control Vessel Vostok and crew arrived in Space Port Nexø carrying the Sapphire rocket and the last materials and supplies. Tomorrow Saturday 24th launch preparations will continue. The rocket will be stacked and fueled and we will go through the entire checkout sequence for all systems. Hopefully everything will work according to plan. If so flight director Kristian Von Bengtson will give the final “GO” and we will head out to the launch area early sunday morning.

Live coverage

Today the StreamTeam has been working on setting up the link antennas. Since we are launching 15 miles of shore getting the output of 8 HD cameras to the internet is a bit tricky, yet the solution is surprisingly simple. At the top of Vostoks masts we have attached a modified WIFI antenna on a rotatable platform. The platform is computer guided and always point at the same point ashore. Approximately 1 mile inland we have placed a 2 foot disc antenna that acts as a internet acess point. This way we are able to sustain a 5-10 mbit internet connection.

The camera signal are then sent to our facility in Copenhagen. Here our producer and  to commentators can see a mosaic of all cameras. The signals are them mixed with audio and broadcasted to Youtube.

The livestream is now avalilable on our website – and we will begin broadcasting approximately 2 hours before launch.

Metal vanes in the nozzle outlet will control the rocket’s direction:
