Siegfried Janson

Senior Scientist

The Aerospace Corporation

Dr. Siegfried Janson is a senior scientist in the Space Science Applications Laboratory at The
Aerospace Corporation. He obtained a Ph.D. in aerospace engineering from Cornell University
in 1984, was a post-doctoral associate at Cornell from 1984 to 1987, and joined the Aerospace
Corporation in 1987 to pursue experimental research in advanced electric thrusters for
spacecraft. He published over 20 papers on electric thruster research by 1995. Dr. Janson’s
current research interests are nano/pico/femtosatellites, membrane spacecraft for orbital debris
removal, spacecraft optical communications, microthrusters, formation flying, micro-
electromechanical systems, and distributed space systems. He started investigating sub-kilogram
mass spacecraft in 1989 and has published over 50 papers on small satellite propulsion
requirements, basic design issues, MEMS for space applications, all-silicon satellites, and small
satellite orbital architectures. Dr. Janson has flown MEMS experiments on sounding rockets,
nanosatellites, CubeSats, the Space Shuttle, and the International Space Station. Dr. Janson
chaired the SPIE “MEMS Components and Applications” conference in 2001, 2003, and 2004,
and is co-editor of the book “Small Satellites: Past, Present and Future.” He is currently the
principal investigator on the NASA-sponsored Optical Communications and Sensor
Demonstration CubeSat program, and the NASA Innovative Advanced Concepts (NIAC) Phase
II program, “Brane Craft.” He is a NASA NIAC fellow, a member of the IEEE, and currently
holds 14 U.S. patents in orbital mechanics, spacecraft attitude sensors, glass/ceramic systems,
thermoelectric coolers, and MEMS fabrication.
