Clementine is MASA's newest single-stage sounding rocket. It utilized groundbreaking technologies including seam-welded propellant tanks, a regeneratively-cooled engine, live in-flight telementry, and full-parachute recovery.

America's largest student-built rocket.

Clementine is MASA's newest single-stage sounding rocket. Clementine utilized a pressure-fed kerolox system and features seam-welded stainless steel propellant tanks, advanced custom avionics, composite aerostructures, a regeneratively-cooled engine, and much more. It stood over 20' tall and is 10.5" in diameter, making it the largest student-built rocket in the United States.
