The company

R-Space is a young start-up with the objective to revolutionize the way of performing In-Orbit Demonstration (IOD) and In-Orbit Validation (IOV) missions by offering a launch within 6 months following contract signature. The GreenBox service developed by R-Space, provides IOD/IOV opportunities for cutting-edge, high risk technologies. The service is designed for an increased speed and ease of access to space. The service targets the traditional space industry involved in upstream technology but is designed in particular for industries with little or no experience with space missions or spacecrafts. In order to achieve this ease of access and simplicity, a series of technological innovations and advanced processes were implemented. On the hardware side, this includes a dedicated payload accommodation unit, a highly modular satellite design and the extensive use of commercial off-the-shelf elements (COTS) and advanced manufacturing methods such as additive layer manufacturing.

The founders

We, the founders of R-Space, have more than 35 years of professional experience in research and development in the field of Aerospace Engineering. Following our work on a successful CubeSat project, we decided to exploit the standardization of CubeSats and develop a service purely dedicated to IOD/IOV missions.


Dr. Wolfgang Treberspurg (CTO)

Wolfgang Treberspurg has specialized in the field of detector development. Especially he coordinated the detector development for the Wide-Field-Imager instrument of the ATHENA mission which sucessfully passed review processes at ESA (MCR, PRR) and presented results at invited speaker at SLAC in Stanford and Trento conference.

Dr. Carsten Scharlemann (CEO)

Carsten has extensive experience in managing research and development (R&D) projects as well as flight projects. His particular research background includes electric propulsion (EP) and chemical propulsion (CP) systems and development and application of nanosatellites. He has led multiple international research consortia for the development of propulsion systems (EP, CP) and alternative (chemical) propellants. Together with his team and the students of the University of Applied Sciences Wiener Neustadt (FHWN), he has developed, launched and operated the first student build CubeSat of Austria.

Dr. Christof Obertscheider (COO)

After completing a doctorate in Applied Mathematics/Astrophysics, Christof has specialized in the field of Computer-Aided Engineering (CAE). This includes Finite Element Method based stress and thermal analysis (FEM), Computational Fluid Dynamics (CFD), Computer-Aided Design (CAD). After spending a substantial number of years working in the aviation industry he has become an academic lecturer. At the University of Applied Sciencies Wiener Neustadt he is the lead engineer for the mechanical subsystem of theĀ CubeSat program.
