Monarch

Built for in-space logistics, Monarch is Stellar Alpina’s first orbiter. It combines detonative propulsion with storable propellants to deliver up to 6,000 m/s of delta-v while remaining compatible with microlaunchers. This lets customers move far beyond their initial launch orbit, reach new orbital regimes, and lay the groundwork for lunar transportation.

✶ CIS LUNAR transportation

The orbiter is only the beginning.

Monarch is designed to move payloads beyond their initial launch orbit and lay the groundwork for future cislunar missions. Stellar Alpina’s future Lunar Lander Morpho is being designed to deliver payloads from lunar orbit to the surface. Together, these vehicles represent a path from orbital logistics to lunar delivery.
