ExoTerra was founded in 2011 with a vision of reducing the cost of space exploration. We pursue this goal by developing affordable technologies that minimize spacecraft mass, including high-efficiency propulsion, miniaturization, in-situ resource utilization, and reusable infrastructure. Our products continue to be enhanced and can be tailored to fit your companies individual needs.
