Lady Elizabeth was designed to compete in the FAR/Mars Society Launch Contest and be recovered using a single bay, two-stage recovery system. Lady Elizabeth was designed and tested in stages with the engine being tested on a test stand before construction of the rocket was started. Lady Elizabeth is the first dual-cryogenic rocket that San Diego State University Rocket Project (SDSURP) has built. This project was worked on by no less than 100 undergraduate and graduate students at SDSU. As of February 1, 2020, Lady Elizabeth holds the altitude record for a student-built liquid bi-propellant rocket launched and recovered at 13,205 feet above ground level (AGL)
