Aquila
An earlier liquid-bipropellant engine program that preceded Juno and helped return ERPL to liquid propulsion development.
ERPL / PROGRAM ARCHIVE
Past projects.
Each program closed a technical gap for the next one. These engines, vehicles, and test systems form the development path behind MOE.
EARLIER FOUNDATIONS
Systems that came before.
Atlas
A mobile stand supporting feed lines and data acquisition for liquid and hybrid engine testing.
Cardea
ERPL's earlier data acquisition and control platform, built around custom electronics for pressure, temperature, load, and valve-state measurements.
