HERMES

High-Efficiency Rendezvous, Maneuver & Execution System

Dynamic Space Operations

Most spacecraft are launched into an orbit and spend their lives defending the propellant to stay there. HERMES is built on the opposite premise: vehicles and operations designed to move, so that maneuver, logistics, and servicing become services a customer can task rather than missions a customer must invent.

Sequenced pillar. Orbit services begin on first defense contracts.

Constanellis sequences five programs from the ground outward: FORGE and NEXUS on the ground, HERMES and WIRES in orbit, ATLAS on the lunar surface. HERMES is the orbit stage of that sequence.

The problem

A static satellite is a fact. A maneuvering one is a capability.

The domain is becoming dynamic: objects that move, inspect, and reposition are now normal in the environment where U.S. and allied assets operate. Responding to that world takes more than watching it. It takes vehicles that can maneuver without regret, deliver mass across orbits, and reach assets that need inspection or support.

Maneuver

Vehicles built to move: repositioning, inspection approaches, and transfers between orbits, flown without treating every burn as a once-in-a-mission event.

Logistics

Delivery and positioning of payloads and consumables across Earth orbit and cislunar space: mass where it is needed, when it is needed.

Servicing

Rendezvous and proximity operations in service of extending, inspecting, and supporting assets that were never designed to be reached again.

Our approach

Operations as the product, gated on contracts.

HERMES is a mission line, not a single vehicle. The engineering center of gravity is guidance, navigation, and control: rendezvous, proximity operations, and efficient transfer, developed against the awareness picture NEXUS maintains and the connectivity WIRES provides.

Like every step outward in the company, HERMES is sequenced. Development proceeds now; missions enter service when defense contracts fund them. We do not build ahead of the customer, and we say so.

HERMES in the sequence

The step between watching the domain and working in it.

Awareness earns the right to operate; operations earn the right to build farther out. HERMES is the middle of the sequence: funded by defense contracts, informed by NEXUS, connected by WIRES.

NEXUS
AI Operations & Cislunar Space Domain Awareness

Dynamic operations run on the awareness picture; HERMES missions consume NEXUS products and feed observations back.

WIRES
Resilient PNT & Communications

Maneuvering vehicles need PNT and communications that hold up when the geometry changes.

ATLAS
Precision Lunar Logistics

The operations discipline proven with HERMES is what makes precision lunar delivery credible.
