Starfish Space finds a new partner for docking demonstration mission
Starfish Space announced on March 26 that it has redirected its Otter Pup 2 docking demonstration after the original partner withdrew in late 2025. The company said the spacecraft, launched in June 2025, had completed a series of orbital tests before the collaboration ended. Starfish confirmed it has secured a new, undisclosed docking partner and has begun maneuvers to bring Otter Pup 2 toward that target, with rendezvous and proximity operations slated to resume in the coming months. No specific date for the revised docking attempt was provided.
Otter Pup 2 was deployed on a SpaceX rideshare mission together with an ION vehicle built by D‑Orbit, which had been slated as the initial docking target. The spacecraft is equipped with an electrostatic capture mechanism that can attach to a flat surface, enabling docking with satellites lacking a conventional docking interface. After the ION partnership dissolved, Starfish consulted a broad set of alternatives before selecting the new partner it will name later. The vehicle’s design supports both rendezvous testing and proximity‑operations validation, and its flight profile includes a planned docking sequence that follows the current maneuver phase. In parallel with the demonstration, Starfish secured a $52.5 million contract from the Space Development Agency to deorbit a platform for the Proliferated Warfighter Space Architecture in 2027, and a $54.5 million U.S. Space Force award to build and operate a GEO servicing spacecraft that will provide mobility solutions such as orbital relocation, graveyard disposal and life‑extension services for five years.
The shift in docking partners underscores the challenges of commercial satellite‑servicing demonstrations that rely on multi‑company coordination. Successful validation of Otter Pup 2’s electrostatic capture could expand the toolbox for on‑orbit servicing, especially for legacy satellites without dedicated docking ports. The concurrent contracts from the SDA and Space Force indicate growing governmental interest in leveraging Starfish’s technology for both defensive space‑debris mitigation and operational flexibility of geostationary assets. Progress on the Otter Pup 2 mission will therefore influence the timeline and confidence of upcoming servicing contracts and may set precedents for future collaborative docking demonstrations.
