Mira launches on SpaceX Transporter missions, hitching a ride to low Earth orbit at a fraction of dedicated launch cost.
Once in orbit, Mira's Saiph thrusters fire to move the customer's payload to its final orbit or trajectory.
After mission completion, Mira separates and either de-orbits or raises itself to a graveyard orbit to avoid space debris.

Impulse Space
Orbital transfer vehicles, Mira, Helios, in-space mobility
Impulse Space develops orbital transfer vehicles (space tugs) that move satellites between orbits after launch. Founded by SpaceX engineer Tom Mueller, the company builds Mira for small payloads and Helios for heavy GEO transfers, with a Mars lander program under way with Relativity Space.
