Tycho Brahe is the first prototype spacecraft designed and built by CS. It is named in honor of the Danish astronomer Thyge Ottesen Brahe (1546-1601). It was originally designed to fit the largest rocket CS believed itself capable of building at the time of its conception in 2008. Thus, it has a diameter of just 64 cm which means the astronaut will be in a half sitting and half standing position, as seen in the original concept drawing below. The top of the spacecraft is an acrylic dome which provides the astronaut a full view of the sky during the flight to and back from space. The spacecraft is now retired after its flight on June 3rd 2011, carried by the HEAT-1X rocket.(www.copsub.com)
