Princeton Rocketry is Princeton University’s continuing student rocketry club, with current project teams spanning IREC, high-power rocketry, orbital, high-altitude ballooning, active controls, and liquid rocket propulsion. Princeton’s official team pages document student design, manufacturing, testing, and flight work across these projects; the active-projects page describes a new liquid-propulsion testbed targeting a first hot-fire in mid-to-late 2026, without claiming that test has occurred.
