We are developing a revolutionary autonomous vehicle to perform satellite servicing missions.
USSF Places Bet on ‘Jetpack’ to Give Aging Satellites New Life, 2024-05-20.
- The Space Force is contracting with startup Starfish Space to build and launch a spacecraft that can dock with and maneuver aging satellites in geosynchronous orbit, a “first-of-its-kind” effort to embrace space mobility and logistics.
- A Starfish spokesperson told Air & Space Forces Magazine the goal is to launch one of its Otter spacecraft by 2026. The company has not yet chosen a launch partner, the spokesperson added.
Starfish Space raises $29M to launch satellite-servicing spacecraft missions, 2024-11-13.
- Launch three full-size satellite servicing and inspection spacecraft in 2026.
- Link added that the company is seeing a “fairly even split” in demand between government and commercial customers.
SpaceX launches Starfish Space’s second spacecraft for orbital satellite docking test, 2025-06-23.
- It could take months for Starfish to work its way through the checklist for Otter Pup 2’s mission objectives. “We want to be able to complete all the major milestones, including the docking milestone, by the end of the calendar year,” Bennett said.
- Otter Pup is designed to demonstrate the technologies that will be used on Starfish’s full-size Otter satellite servicing vehicles. Such vehicles are being built to link up with satellites on a regular basis — to refuel and service them for extended missions, or to push them out of their orbits for safe disposal at the end of their missions.
NASA Eyes Private Companies For Swift Orbit Raise, 2025-08-13.
- NASA hired four companies to figure out how to raise the orbit of a two-decade-old space observatory that still provides important data to scientists.
- The agency is leveraging SBIR study contracts to assess the feasibility of a rescue mission that would take place in 2026.
- Katalyst Space Technologies, which is already planning to demo a spacecraft capable of grappling another satellite in 2026.
CEPHALOPOD
Our CEPHALOPOD Software Package
Starfish’s CEPHALOPOD software was selected as a winner
of the Hyperspace Challenge! Satellite, Rendezvous, Proximity Operations, and Docking (RPOD) missions are difficult, but open up new opportunities in space. Making use of electric propulsion
and small spacecraft technologies can enable modern, efficient RPOD missions.
We advance on-orbit transportation with versatile, affordable and reliable servicing vehicles.
CEPHALOPOD is autonomous RPOD software that can use electric propulsion, enabling small RPOD spacecraft. This on-board guidance, navigation, and control capability can give small servicing vehicles 8x more maneuvering capability.
- Enables RPOD missions with EP.
- Highly autonomous on-board operations.
- Reduce vehicle mass and cost.
- Significant built-in safety features.
The Nautilus Capture Mechanism
The versatile mechanism works on surfaces that were not designed for docking.
- Adheres to broad set of capture surfaces
- Dynamic damping of docked bodies
- Many mission reuse capability
- Multi-year operational life
The Nautilus capture mechanism attaches to satellites for docking and manipulation.
Status Comment
Satellites have been launched but servicing has not been demonstrated as of August 2025.
Starfish spacecraft will extend the life of an expensive GEO satellite in 2026 mission, 2024-06-26.
