|---|---|---|---|---|---|
Astroscale 186A:JP | ISAM · Orbital Transport & Tugs | ELSA-M (Debris Removal) and LEXI (Life Extension). | The Garbage Collector | Orbital Hygiene. The Kessler Syndrome is the ultimate bottleneck. You cannot launch more clouds if the orbit is full of junk. | High |
Starfish Space Private | ISAM · Orbital Transport & Tugs | Otter (Satellite Servicing Vehicle). | The Space Tug | Asset Stranding. Satellites often run out of station-keeping fuel while their electronics are still fine. Starfish docks to extend revenue-generating life. | Long |
Katalyst Private | ISAM · Orbital Transport & Tugs | In-space servicing and life extension technology. | The Mechanic | Asset Life Extension. Solves the CapEx waste of de-orbiting functional satellites due to fuel/part failure. | Speculative |
Northrop (SpaceLogistics) $NOC | ISAM · Orbital Transport & Tugs | MEV (Mission Extension Vehicle) & MRV (Robotic Vehicle). | The Tow Truck | Life Extension. Northrop's subsidiary, SpaceLogistics, is the only entity in history to commercially dock with and extend the life of a dying satellite in GEO. | High |
Blue Origin (Blue Ring - Transport) Private | Orbital Transport & Tugs | Blue Ring (Orbital Maneuvering). | The Heavy Tug | The 'Last Mile' Gap. Launch vehicles drop you in LEO. Getting to GEO or Cislunar requires high-energy maneuvering. Blue Ring provides the 'Delta-V' as a service. | Watchlist |

Firefly (Elytra) Private | Orbital Transport & Tugs | On-orbit service vehicles (Elytra Dawn/Dusk) integrated with Firefly launch. | The Utility Tug | Orbit Flexibility. Launch only gets you to the drop-off point; Elytra solves the 'Last Mile' to specific orbital slots. | Neutral |
D-Orbit Private | Orbital Transport & Tugs | ION Carrier for precise cube-sat deployment. | The Delivery Truck | Precision Deployment. Solves the 'Phasing' problem for constellations launched in batches. | Neutral |
Intuitive Machines $LUNR | Orbital Transport & Tugs | Nova-C Landers and Lunar Data Relay services. | The Cislunar Ferry | Lunar Access. As the 'Cloud' expands to the Moon (xGEO), LUNR owns the landing and data relay infrastructure. | High |
