HPGP

High Performance Green Propulsion (HPGP) is a rocket propellant developed as a safer alternative to hydrazine.[1] HPGP is based on ammonium dinitramide mixed with ammonia and methanol. Its specific impulse is around 235 seconds. The Prisma mission serves as a demonstrator mission for HPGP.[2]
