Commercial Docking Pioneered in Orbit by Starfish Space's Otter Satellite
The Otter Pup 2 mission, scheduled for launch in June 2025, is a groundbreaking endeavour by Starfish Space. This mission seeks to revolutionise satellite servicing in low Earth orbit (LEO) by attempting the first commercial satellite docking.
Mission Objectives
The primary objective of Otter Pup 2 is to demonstrate the ability to dock with another satellite. This capability could pave the way for a range of new possibilities in satellite servicing, such as refueling, maintenance, and upgrades while in orbit.
By successfully docking, Otter Pup 2 will also validate Starfish Space's core technologies. These technologies are designed to enhance the utility and lifespan of satellites in LEO, potentially changing how satellites are maintained and repurposed.
Impact on Satellite Servicing
If successful, the mission could lead to more efficient satellite operations. Satellites could be repaired or upgraded in orbit, reducing the need for costly replacement missions and extending their operational lifespan.
The ability to dock and service satellites commercially could open new business models, such as offering on-orbit maintenance services to satellite operators. This could significantly reduce operational costs and enhance the overall value of satellites in LEO.
Broader Implications
The success of Otter Pup 2 would contribute significantly to advancing space technology, particularly in the area of interactive satellite operations. This could pave the way for more complex missions and applications in space, such as the assembly of large structures or the creation of modular space-based systems.
By extending the life of satellites and enabling more efficient operations, the mission could also contribute to reducing the environmental impact of space activities, such as minimising space debris through more controlled satellite retirement and reuse.
The Otter Spacecraft
The Otter spacecraft, developed by Starfish Space, is roughly the size of a microwave oven and relies heavily on sophisticated software rather than bulky hardware. Equipped with advanced software, a new electric propulsion system from ThrustMe, and a universal docking system called Nautilus, the Otter is uniquely suited for the challenges of docking with an unprepared satellite in LEO.
The Otter's navigation software, CETACEAN, uses computer vision to determine its position and orientation relative to the target satellite. Meanwhile, the guidance and control software, CEPHALOPOD, plans and executes safe approach maneuvers using electric propulsion.
Partnerships and Collaborations
The Otter Pup 2 mission involves several industry partners, including Astro Digital for the satellite's bus, Redwire Space for the Argus camera system, and Honeybee Robotics for parts of the Nautilus docking mechanism. The mission highlights the teamwork driving innovation in the space industry, with each partner bringing expertise to make the mission possible.
Previous Endeavours and Lessons Learned
The Otter Pup 2 mission builds on the lessons learned from the unsuccessful Otter Pup 1 mission in 2023, where the spacecraft entered an uncontrolled spin during deployment. Starfish Space has taken these lessons to heart, making significant improvements to ensure the success of Otter Pup 2.
The successful completion of the Otter Pup 2 mission could validate Starfish Space's technology and set the stage for a future where satellites can be repaired, refueled, and repositioned, making space operations more sustainable and versatile.
