Pharus is the first rocket to be designed and built by the Sioux Falls Space Association that is not classified as a model rocket. Replacing the need for the third section of the Fortuna series, the Pharus rocket will serve as a platform to test new technology such as altimeters, gyro sensors, apogee detectors, parachute pistons, and possibly a prototype SUIT Module. Along with testing new technology, Pharus will be an attempt at almost complete reusability.

Pharus (according to current plans) will be 1.8 meters tall, 7.6 centimeters wide, and weigh over 10 kilograms when fully fueled. The rocket will incorporate a casted engine that spans 0.9 meters of the rocket, with an apogee detector and parachute piston filling the rest of the rocket. Upon completion, Pharus is expected to reach an apogee of 1905 meters, with a maximum velocity of 189.9 meters per second. During flight, the engine will have an impulse of 2273 Newton-seconds, with an average thrust of 511 Newtons.
