Company Overview

About Impulse Space

Impulse Space develops orbital transfer vehicles (OTVs) — spacecraft with high-performance chemical propulsion systems that can transport satellite payloads from launch vehicle deployment orbits to their operational orbits, or maneuver constellations for rapid response missions. The company's Mira vehicle targets LEO and MEO missions while the larger Helios vehicle aims for GEO and cislunar missions.

Business Model & Competitive Advantage

Founded in 2021 by Tom Mueller, the co-founder and chief propulsion engineer of SpaceX who designed the Merlin rocket engine, Impulse Space has raised $150M and launched its first Mira demonstration mission in 2023. The company's propulsion expertise — using high-performance bipropellant engines — delivers significantly more delta-v (velocity change) than electric propulsion alternatives, enabling faster orbital transfers for time-sensitive commercial and defense missions.

Competitive Landscape 2025–2026

As satellite constellations proliferate and responsive space launch becomes a military priority, in-space transportation services that quickly move payloads to precise orbits become strategically valuable. Impulse competes with Exolaunch, D-Orbit, and Momentus in the rideshare last-mile delivery market, and with Rocket Lab's Photon and MAXAR's Saturn vehicle for larger propulsion class missions.
