Andromeda Space

We're building the world's first in-space transportation network.

From LEO to lunar, persistent infrastructure connecting every orbital destination. Vehicles that stay on orbit. Hubs that never come down. A network built for the long run.

Perseus deploys to LEO first. Chariot extends the network cislunar and beyond.

Persistent.
Vehicles and hubs that stay on orbit between missions. No launch delay. No standing up from scratch each time.
Pay per leg.
Hub-to-hub pricing. Overhead stays with the network, not with you. The same way a carrier charges per segment, not per rail line.
Every destination.
LEO, GEO, cislunar, lunar. One network, not one vehicle per mission. Perseus is Phase 1. Chariot takes it the rest of the way.
Phase 1 — In Development
Perseus OTV
The first vehicle on the network. ~50 kg, 3 km/s delta-V, persistent on-orbit. First flight Q1 2028.

In-Space Mobility as a Service

Your satellite,
repositioned in hours.

Perseus is the world's first persistent on-orbit transfer vehicle. It stays in space between missions. When your satellite needs a maneuver, Perseus is already there. You pay per maneuver, not per launch.

Perseus OTV spacecraft
Perseus OTV

Persistent. Resident. On call.

Every existing orbital transfer vehicle launches, completes a single mission, and leaves. Perseus operates from orbit. It commissions into your orbital shell and stays there — ready when you need it.

Payload capacityUp to 150 kg
Delta-V3 km/s
Orbital regimesLEO, MEO, GEO, Cislunar
Services

Everything your satellite needs, on demand.

Perseus executes the full range of orbital mobility operations. No new launch required.

Slot Correction On-Demand Repositioning Conjunction Avoidance EOL Deorbit Constellation Phasing Responsive Repositioning On-Orbit Inspection Payload Hosting
Business Model

Phase 1: a commissioning fee puts Perseus in your orbital shell. Andromeda covers the launch cost. From there, you pay per maneuver, the same way a utility charges per kilowatt. No retainer. No launch overhead. Just mobility when you need it.

Perseus Swarm System

Persistent.
Autonomous.
Resilient.

No single point of failure. No continuous ground contact required.

Perseus operates across LEO, MEO, GEO, and cislunar without continuous ground contact. When ground links are jammed or degraded, the swarm keeps executing. Autonomous onboard decision-making ensures the mission continues under contested conditions.

Why Perseus

Built different from the ground up.

Most on-orbit vehicles launch, execute one mission, and deorbit. Perseus was designed to operate continuously, refuel, and reconstitute — giving defense customers a fundamentally different capability profile.

01
Always On Orbit
Perseus doesn't launch for each mission. It's already there. Responsive repositioning in hours, not the months it takes to plan and execute a new launch.
02
3 km/s, Any Condition
Bipropellant propulsion. Full thrust in eclipse. No solar dependency. No mission gap when the Sun angle is wrong. Operable any time, any lighting condition.
03
Depot Refuelable
Perseus refuels from on-orbit depots. Unlimited operational life. A mission doesn't end because the tank is empty — it ends when the objective is complete.
04
Fault-Tolerant Swarm
Multiple vehicles. Coordinated autonomy. Loss of one vehicle doesn't end the mission — the swarm reconstitutes and continues. No single point of failure.
05
Autonomous Under Contested Comms
Onboard ML decision-making enables Perseus to operate through jamming, blackouts, and degraded link conditions. Autonomous RPO without continuous ground contact.
06
Pay Per Maneuver
One vehicle serves multiple clients and missions. Low-cost access to high-delta-V capability without the overhead of a dedicated spacecraft for each operation.
Autonomous
Distributed
Resilient
Perseus Swarm System

Multi-vehicle. Coordinated. Survivable.

The Perseus Swarm System deploys a coordinated constellation of vehicles capable of autonomous multi-vehicle operations without continuous ground contact. Each vehicle makes onboard decisions. The mesh survives individual vehicle loss.

  • On-orbit inspection and characterization of resident space objects
  • Space Domain Awareness support across LEO, GEO, and cislunar
  • Autonomous rendezvous and proximity operations under degraded comms
  • Coordinated custody maintenance of maneuvering objects
  • Responsive repositioning without a new launch
  • Multi-mission reuse across inspection, transfer, and defense profiles

Why Now

Three catalysts. One window.

The in-space logistics market exists because three independent trends converged at the same moment.

01
Launch costs fell.
The bottleneck is no longer getting to orbit. What happens after launch is. Persistent in-space infrastructure is now economically viable in a way it never was before.
02
LEO is congested.
Conjunction avoidance, slot correction, and constellation phasing are daily operations problems for growing satellite fleets. Onboard propellant budgets can't cover it all.
03
Defense demand is rising.
DoD is actively investing in autonomous, resilient in-space capabilities. Space Domain Awareness and responsive repositioning are program priorities — and no persistent solution exists yet.

Business Model

Recurring revenue.
Compounding fleet.

Phase 1: a commissioning fee plus pay-per-maneuver. Andromeda covers launch. As the fleet scales, operators pay only for the delta-V they use.

Year Fleet Model Target ARR
2028 3 vehicles Commissioning + pay-per-maneuver ~$2M
2029 5 vehicles Operators pay delta-V only ~$5M
2030+ 10+ vehicles Fleet scale, Chariot R&D begins ~$10M

The long-term architecture (Chariot) builds a hub-and-spoke cislunar logistics network — the infrastructure layer for the space economy.

Team

Built by engineers who fly things.

Our team met through WARP — a student rocketry program that broke altitude and speed records, built a 15-foot two-stage rocket designed to reach the Karman Line, and briefed Space Force leadership at the Pentagon. Two Andromeda cofounders were WARP founding members.
