ASCENT (Advanced Spacecraft Energetic Non-Toxic) is a monopropellant developed by the US Air Force Research Laboratory (AFRL).

Benefits of ASCENT vs. Hydrazine:

- 50% superior impulse density relative to state-of-the-art monopropellants allowing for more mission with equivalent system size

- Novel 'multi-mode' propellant for both chemical & electric propulsion providing high-thrust and high-efficiency within a single simplified and dynamically tunable system

- Long-term storable with improved spacecraft thermal management, making previously impractical missions possible

- Safe handling and significantly reduced time and cost for ground integration and propellant loading enabling tactically responsive launches and high-volume rideshare missions

- Simplified shipping, storage & handling (DOT-certified) reducing logistical costs and enabling shipment and storage of fueled spacecraft
