Welcome! We are the CU Sounding Rocket Laboratory, the University of Colorado at Boulder's rocketry development and launch program, providing engineering experience and launch capabilities. We are a student-operated group under the Department of Aerospace Engineering Sciences, and are independently funded through the Engineering Excellence Fund and corporate and individual sponsorships. We have been active since 2014, and we are now undertaking many technical projects, including work involving mixing custom solid rocket propellant, developing flight software for our avionics hardware, advanced composites manufacturing, hypersonic aero-thermal simulations, and a liquid-fueled rocket engine.
