Agena Space provides RocketPack, a modular green liquid‑propulsion system for SmallSats that uses high‑purity H₂O₂ monopropellant or H₂O₂/propene bipropellant to deliver 1‑500 N thrust with specific impulse up to 300 s. The plug‑and‑play units include integrated flight electronics, a spherical membrane tank for long‑term storage, and are ITAR‑free, enabling precise orbital maneuvers, de‑orbiting, and on‑orbit servicing for satellite manufacturers and launch providers.

Problem
Small satellite missions often lack affordable, compact propulsion that can perform precise orbital maneuvers, de‑orbiting, and on‑orbit servicing while meeting sustainability requirements. Conventional chemical thrusters are bulky, expensive, and rely on hazardous propellants, limiting design flexibility and increasing launch costs.
Solution
Agena Space delivers RocketPack™, a family of green liquid‑propulsion modules built around high‑purity H₂O₂ monopropellant and H₂O₂/propene bipropellant chemistries. The units are engineered for a thrust envelope from 1 N up to 500 N, offering specific impulses of 170 s (mono) to 300 s (bi) and total impulse capacities ranging from 5 kN·s to 220 kN·s. RocketPack™ is offered as a turn‑key, plug‑and‑play subsystem that can be mounted on SmallSats, launch vehicle RCS stages, or an autonomous satellite bus that hosts customer payloads. The architecture supports modular scaling of thrust, propellant mass (6 kg‑75 kg), and physical dimensions, enabling mission‑specific optimization of size, layout, and redundancy. Integrated electronics provide CAN and RS‑422 interfaces, 24‑36 V power handling, and over 25 000 restart cycles, while the proprietary PropBall™ spherical membrane tank ensures long‑term storability and zero‑debris compliance. All hardware is ITAR‑free, allowing unrestricted global integration and rapid certification.
Target Audience
Primary customers are SmallSat manufacturers, satellite operators, and launch service providers that require reliable, low‑cost propulsion for orbit transfer, attitude control, collision avoidance, and end‑of‑life de‑orbiting. The solution also serves mission integrators developing on‑orbit servicing or rapid‑deployment payloads.
