Spring 2026 conference is live!
We (almost) broke a world record.
On June 1st, 2025 we prepared to launch “Big Liquid” – our first flight-ready liquid-rocket – to 80,000 ft, a student group record.
Unfortunately, the vehicle suffered an on-board fill valve malfunction which caused oxidizer to be dumped out of the fill decoupler following ignition and decoupling.
As we progress toward a space capable liquid rocket, validating our subsystems and launch processes is absolutely critical. Big Liquid helped us do that, and taught us how to scale effectively.
Apogee: 6,439 ft
Mach 0.43
Similar to 2022's Redshift we've opted for a "sub-minimum diameter" design, meaning the propellant tank doubles as a section of the airframe and is exposed, with the lower and upper airframes slipping over it.
Developed by Jackson Dendy, this Monte-Carlo integration for RocketPy allowed us to complete dispersion analysis of the rocket's landing points for our FAA Class III waiver.
