Following the lessons learned from the setback of Aftershock I (ASI), the mission of Aftershock II is to become the highest and fastest student-built rocket ever. It’s the aspirational successor to Traveler IV, USCRPL’s first successful spaceshot. With every aspect of the rocket redesigned and improved, Aftershock II aims to break records in both student and amateur rocketry, reaching new heights and speeds. Here’s a look at the goal:
🌌 Highest Altitude Achieved (Student Amateur Rocketry)
• 2019: USCRPL’s 'Traveler IV' reached 339,800 ft (103.6 km) - Student Record. • 2014: 'GoFast' reached 385,800 ft (117.6 km) - Amateur Record. • 2024: Aftershock II aims to reach 490,000 ft (149.0 km), nearly at the FAA limit for amateur rockets of 492,000 ft (150.0 km).
đź’¨ Fastest Velocity Achieved (Student Amateur Rocketry)
• 2019: USCRPL’s 'Traveler IV' reached 4,966 ft/s (1,513 m/s) - Student Record. • 2014: 'GoFast' reached 5,250 ft/s (1,600 m/s) - Amateur Record. • 2024: Aftershock II is simulated to reach 5,600 ft/s (1,700 m/s), aiming to shatter both speed records.
With Aftershock II, USCRPL is reaching for the stars and aiming to redefine the limits of student and amateur rocketry. Stay tuned as we push the boundaries and make history! 🚀✨
