Nereus thrusters
A family of small in-space thrusters running on hydrogen peroxide. The first announced customer, a private reentry capsule maker, plans to fly a Nereus system in early 2027.
Why it matters
Capsules and small spacecraft need compact thrusters for orbit changes and deorbit burns. Nereus avoids the toxic propellants many small thrusters use, which makes handling on the ground simpler.
How the technology works
Nereus comes in monopropellant and bipropellant versions from 1 N to 1.5 kN, using hydrogen peroxide with jet fuel in bipropellant mode. Customers can buy a thruster alone or a full system with tanks, feed lines and avionics.
An undisclosed private customer developing a reentry capsule will integrate one for a mission expected in early 2027.
