Impulse Space
In-space mobility company developing maneuverable spacecraft and propulsion systems for rapid transport, hosting, deployment, and proximity operations across orbits.
The product
Mira maneuvering spacecraft, Helios high-energy kick stage, Caravan rideshare services, Electra electric propulsion, and in-house chemical propulsion systems.
The thesis
Launch reaches an initial orbit; Impulse is building the post-launch transportation layer needed to reposition payloads, respond quickly, inspect objects, and reach higher-energy destinations.
How it runs
Designs, manufactures, tests, and operates spacecraft and propulsion, offering complete mobility missions and vehicles to commercial, civil, and national-security customers.
How it earns
Commercial transport and rideshare agreements plus U.S. government spacecraft, responsive-space, and launch-program contracts; private capital funds vehicle development and production expansion.
Why it wins
Flight-proven Mira operations combined with vertically integrated propulsion and a product ladder spanning LEO maneuvering, high-energy transfer, rideshare, and electric propulsion.
