Welcome to the Colorado Space Grant Consortium (CoSGC) Hermes CubeSat webpage. Hermes is the first CubeSat under construction at the CoSGC headquarters at the University of Colorado in Boulder. The CoSGC CubeSat program, known as CO3 (Colorado Cubed), hopes to use Hermes as the starting point for an extended program of CubeSats. Ideally, there will always be one CubeSat under development at any time and another on-orbit.

The Hermes CubeSat is built in accordance with the specifications set forth by the California Polytechnic State University (CalPoly) CubeSat Foundation and is currently in its post-Critical Design Phase and is in the heart of FlatSat testing and flight hardware construction.

Launch is currently planned for the end of 2008 or early 2009 to a high-inclination low earth orbit. The project completion deadline is May 1st, 2008, and all hardware will be completed and fully tested by that date.

** As of March 13, 2008, the website is still under construction after much delay. Please check back often as it will continue to be updated to reflect the current state of the Hermes mission. After May 1st, a big push will be made to publish the majority of our project information on this site. It is our hope that this website will actually provide useful and detailed information about our project that is both easy to understand and technically specific enough to help other CubeSat designers. Feel free to contact us if you have any questions or would like more information.
