A unique binder was developed that exhibits a glass transition temperature of –100 °C, which is more than 50 °C lower than that of traditional HTPB (hydroxyl-terminated polybutadiene) and CTPB (carboxyl-terminated polybutadiene) binders. This innovation would be a solid propellant that would ameliorate low-temperature operability problems for the two-stage Mars Ascent Vehicle (MAV).
