The big picture: Satellite constellations are getting crowded, but current propulsion is either too slow or too toxic. ISPTech is replacing hazardous hydrazine with “green” engines to enable precision maneuvering and safe de-orbiting.
Why it matters:
- Regulations: Europe is phasing out toxic propellants; manufacturers need immediate, non-toxic alternatives.
- Mobility: In-orbit servicing and collision avoidance require instant, repeatable thrust that electric propulsion can’t always match.
How it works:
- HyNOx: A self-pressurizing system for small sats—no complex pumps required.
- HIP_11: Hypergolic performance without the chemical risk, built for larger spacecraft.
- Status: First mission set for 2026; backed by ESA projects for orbital refueling.
The catch: ISPTech is fighting “flight heritage” bias. Space operators are notoriously risk-averse; proving multi-year reliability against legacy aerospace giants will be its steepest climb. Much like the hurdles seen in autonomous engineering, ISPTech must prove that its non-toxic engines can maintain precise thrust consistency over multi-year missions without the reliability degradation common in early-stage hardware.
