OTESting
OTESting - First commercial milestone
The OTESting will be a sub-orbital fully reusable single stage micro-launcher based on the R2D2 design. It will be equipped with 8 PEPEk-1 enginesand later with 4 PEPEk-1 and a single PEPEk-4 engine. It will be able to lift approx. 50kg of payload to approx. 150km altitude. It will provide a 3.5 to 5 minutes at microgravity conditions.
