Orbital transfer vehicle (OTV) for last-mile payload delivery in LEO and beyond. ~300 kg. Uses eight Saiph thrusters (22 N each, N2O/ethane). First flight November 2023 (Transporter-9, LEO Express-1); second flight January 2025 (Transporter-12, LEO Express-2). Autonomous plane changes, LTAN changes, payload deployment, and proximity operations.

### Who makes Mira?

Mira is made by Impulse Space, based in Redondo Beach, California, USA, founded in 2021.

### Where is Mira deployed?

3 verified deployments of Mira are on the DEPLOY registry, including at Geostationary Orbit (GEO), Low Earth Orbit (LEO).

### What is Mira's maturity stage?

Mira is at the commercial stage on the DEPLOY maturity ladder (research, prototype, pilot, commercial, production). Commercial stage means production-grade deployments are operating at named customer sites.
