Space Propulsion Market

Once a satellite separates from the rocket, it needs its own propulsion system to reach its final orbital slot, maintain that position against atmospheric drag, and eventually de orbit safely at end of life. This market is bifurcating. You have chemical propulsion (hydrazine based) for fast, high thrust manoeuvres, and electric propulsion (Hall Effect Thrusters, Ion Thrusters) for slow but extremely fuel efficient station keeping. The holy grail right now is “green propulsion”, which uses non toxic propellants that are safer to handle on the ground.

What Numbro covers:

Global market sizing by thruster type: Chemical (Monoprop/Biprop), Electric (Hall Effect/Gridded Ion), and Green Propulsion alternatives (ASCENT, LMP 103S). Component deep dive on high voltage power processing units (PPUs) required for electric thrusters. Regulatory analysis of de orbiting rules (FAA 5 Year Rule) and the impact on propulsion system selection. India ecosystem mapping of propulsion startups (Manastu Space, Bellatrix Aerospace) and their technology validation progress.
