Amateur Rockets and Nano-Satellites
The Portland State Aerospace Society is a multi-disciplinary group of engineering students and industry professionals. We design, build, and fly our own rockets! Ours are not the toy models you may be familiar with; they're over ten feet tall, and are equipped with sophisticated avionics. Our (very) long-term goal is the development of a launch vehicle capable of placing a nano-satellite into low earth orbit.
