 Program Overview
The goal of the Chimera program is the design and construction of a family of safe and reliable hybrid rocket vehicles of increasing capability, ranging from suborbital flight to orbital insertion. It is anticipated that the later stages of Chimera will use hardware from earlier stages, through staging and/or clustering, allowing a wide range of flight capabilities with a minimum range of hardware.
