DARE Unveil Stratos IV

I am a little late to this, but the student team from TU Delft have recently unveiled their new Stratos IV rocket. Stratos III, which launched last year to break the European amateur and student altitude record was lost 20 seconds into flight due to a roll-pitch coupling. Stratos IV will carry on the legacy of its predecessor and will use essentially the same hybrid rocket motor, but with a titanium nozzle, a nitrous mono-propellant thruster roll control system, longer fins, and a more rigid fuselage. With all this taken into account, the rocket will reach 100 km in altitude and thus space. To do this the team plan to launch from Denel Overberg Test Range in South Africa, this is the same place that UKZN’s sounding rocket launched from.
