Mira

Our flight-proven orbital transfer and hosting vehicle for LEO, MEO, GEO, and Cislunar missions.

Fly with Mira

Mira is a high-performance spacecraft for payload hosting and constellation deployment. Mira’s high delta-v capability and 6DOF control provide exceptional versatility for rendezvous and proximity operations (RPO) and space situational awareness (SSA). Flying since 2023, Mira continues to set the standard for orbital transfer vehicle (OTV) performance.
