About

Stephan Siegfried Jahnke is a space systems engineer whose research focuses on the future of human spaceflight, lunar exploration architectures, and power system optimization for extreme environments. His work is defined by a pragmatic, systems-level approach to making space more accessible. His most influential paper, "The Orbital-Hub: Low Cost Platform for Human Spaceflight after ISS" (2016, 4 citations), proposes a paradigm shift away from monolithic space stations toward a more modular, cost-effective orbital infrastructure. Jahnke also made significant contributions to the ROBEX (Robotic Exploration Under Extreme Conditions) alliance, where he helped develop and validate key technologies for modular lunar surface missions. His paper on the ROBEX demonstration mission on Mt. Etna (2017, 2 citations) describes a terrestrial analog mission that successfully deployed seismic experiments using a modular landing system and mobile elements—a direct precursor to future lunar operations. Additionally, his work on power system analysis and optimization for a modular experiment carrier during an analog lunar demo mission (2018, 4 citations) demonstrates his commitment to solving the practical engineering challenges of sustained off-world operations. Jahnke’s research bridges the gap between current space station operations and a future of affordable, distributed human and robotic exploration.
