Rendezvous
Establish the mission profile, approach corridor and relative position before a servicing vehicle closes in.
Navigation & approach planningTHE NEXT CHAPTER OF ORBITAL OPERATIONS
More mission.
Less limitation.
In-space refueling can help valuable spacecraft keep working longer.
We’re exploring reusable in-space refueling infrastructure that can extend spacecraft working life and give operators more options after launch.

01 / THE VISION
A launch is the beginning.
Not the entire plan.
What if a spacecraft’s next chapter didn’t require starting again on the ground?
Orbital Refilling is a concept for a reusable servicing network in space. We’re exploring how refueling, mission planning and compatible interfaces can extend spacecraft operations and support more flexible missions.
Inside the concept ↗02 / THE ARCHITECTURE
One mission.
Four connected moments.
A reference approach to orbital servicing, from a carefully planned encounter to a new mission horizon.
02
Dock & verify
Explore compatible interfaces, controlled capture and the checks required before propellant transfer.
Interfaces & connection integrity03
Transfer
Study fluid handling, transfer monitoring and isolation as part of a mission-specific refueling system.
Propellant management & monitoring04
Continue
Verify separation, review the servicing outcome and plan the spacecraft’s next operational phase.
Mission continuation & reuseReference architecture under exploration. Interfaces and feasibility depend on the spacecraft and mission.
03 / WHERE IT COULD MATTER
Designed around
the mission ahead.
Different orbits. Different constraints. A shared question: how can useful spacecraft keep doing useful work?
Earth observation
Explore servicing strategies for high-value platforms where continuity, maneuverability and mission flexibility matter.
LOW EARTH ORBIT
Communications
Evaluate refueling as part of a longer-term operating strategy for compatible communications spacecraft.
GEOSTATIONARY ORBIT
Beyond Earth orbit
Consider reusable logistics and replenishment concepts for transfer vehicles and future cislunar operations.
CISLUNAR SPACE04 / OUR STARTING PRINCIPLES
Think in systems.
Build toward trust.
Technical ambition needs a clear view of the constraints.
Mission fit before promises
Start with the orbit, platform, propellant and operator’s objectives. Compatibility is a question to resolve, not assume.
Safety at every interface
Make approach, capture, transfer and separation explicit parts of the architecture and its future verification plan.
Reuse as a design objective
Explore servicing vehicles and operational models that could support repeated missions and responsible orbital activity.
What is Orbital Refilling?
A WebGeneric concept exploring reusable in-space refueling and servicing infrastructure for spacecraft with useful life remaining.
Is this an operating service today?
No. It is an open concept at the exploration stage, intended to create better conversations between operators, engineers and strategic partners.
What would a first conversation cover?
Orbit, platform, propulsion, timing, mission constraints and the evidence needed to understand whether a servicing pathway is worth exploring.
Can we collaborate on the model?
Yes. The concept is deliberately open to people who can sharpen the interfaces, economics, safety case and operating reality.
