A brand new mission will purpose to finish the primary industrial satellite tv for pc docking in low Earth orbit (LEO). Nevertheless, the satellite tv for pc it goals to dock with isn’t geared up with a docking adapter.
Starfish House is hoping to show the idea of having the ability to dock to unprepared satellites for restore, refueling, or repositioning in orbit. The mission, generally known as Otter Pup 2, is now set to launch aboard the SpaceX Transporter-14 rideshare mission.
This follows the corporate’s first try, which noticed the Otter Pup 1 mission unable to dock with its goal on account of a thruster failure.
The Otter Pup 2 spacecraft shall be deployed from 1 / 4 plate on the higher stage adapter of the SpaceX Falcon 9 rocket, putting it right into a solar synchronous orbit altitude of 510 km inclined 97.4 levels.
The goal shall be a D-Orbit ION spacecraft which can simulate a shopper payload, which isn’t geared up with a conventional docking adapter or seize plate as you would possibly see aboard an area station or different rendezvous goal.
As an alternative, Starfish House’s Nautilus seize mechanism will function a particular finish effector related to the tip of the seize mechanism. This finish effector will allow Otter Pup 2 to dock with the ION by electrostatic adhesion.
“An electromagnet shall be built-in into the tip effector and shall be used as a backup choice to the electrostatic finish effector, to dock with the ION by magnetic attraction,” the corporate notes.
The purpose is to ultimately fee its Otter satellite tv for pc servicing automobile to permit for servicing of beforehand launched satellites. The corporate’s first Otter missions embody prospects equivalent to NASA, the U.S. House Pressure, and Intelsat, with the purpose of flying these missions as quickly as 2026.
“This permits us to make Otters an order of magnitude smaller than different servicing autos—making them sooner to construct, sooner to launch, and eventually closing the enterprise case for satellite tv for pc servicing to scale throughout the area business,” Starfish House co-founder Trevor Bennett mentioned in a press launch.
Following the thruster points on the primary mission, this flight will function two ThrustMe thrusters, which use an electrical propulsion system primarily based on gridded ion thruster expertise.

Consistent with the nautical theme, the mission can even be testing its distinctive rendezvous and docking software program. The autonomous relative navigation software program, referred to as CETACEAN, will decide the relative state between Otter Pup 2 and ION utilizing a mixture of onboard sensors. That is paired with the Argus digital camera, which incorporates two stereo cameras for figuring out depth and distance with the assistance of further on-board picture analysis programming.
The autonomous onboard steerage and management software program, named CEPHALOPOD, is designed to make use of low thrust with a purpose to make rendezvous and docking attainable utilizing solely electrical propulsion.
The 40 kg spacecraft measures 86.3 cm by 38.9 cm by 107.7 cm absolutely deployed. The Otter Pup 2 mission will see the spacecraft first take a look at proximity operations, getting shut and positioning itself across the goal. That shall be adopted by short-term dockings and undockings to check out the system.
The 2 spacecraft will then separate from one another. Atmospheric friction is predicted to sluggish the spacecraft and scale back the altitude till it reenters lower than 5 years after the tip of the mission.
In response to Starfish House, the purpose isn’t simply to show the docking expertise works, however to permit for an inexpensive strategy to satellite tv for pc servicing.

“For the reason that begin of the House Age, humanity has despatched satellites into orbit understanding they’ll be on their very own,” the corporate mentioned in a press launch. “With no inexpensive, sensible choices for servicing as soon as in orbit, satellites should be totally self-sufficient—enormously constraining how they are often constructed, how a lot they’ll do, and the way lengthy they’ll final.”
Transporter-14 is at the moment scheduled to launch no sooner than June 1, 2025.
