Overview of the Remora Mission
The Remora mission, a collaboration between Starfish Space and Impulse Space, successfully demonstrated autonomous close approaches between two Mira spacecraft in Earth orbit. This mission marked a significant milestone in the development of satellite servicing technologies, showcasing the capabilities of Starfish's guidance and navigation software. The operation took place in late October 2025, with one Mira spacecraft approaching another to within approximately 4,100 feet (1,250 meters).
Technical Details and Execution
The Remora mission utilized a single lightweight camera and Starfish's core guidance, navigation, and control (GNC) software, known as Cetacean and Cephalopod. This software processed images from the camera to generate navigation data and maneuver commands, allowing the approaching Mira to autonomously close the distance to the target spacecraft. Trevor Bennett, co-founder of Starfish Space, emphasized that this approach differed from traditional methods, which often rely on complex hardware setups. Instead, the mission demonstrated that off-the-shelf cameras could suffice for such operations.
Eric Romo, President and COO of Impulse Space, noted that the mission validated the maneuverability and precision of the Mira spacecraft, which employs high-thrust chemical propulsion. The successful close approach was achieved after the Mira spacecraft completed its primary tasks during the LEO Express 2 mission, launched in January 2025.
Implications for Future Missions
The success of the Remora mission opens up new opportunities for both companies in the realm of rendezvous and proximity operations (RPO). Starfish Space is developing a series of Otter spacecraft designed for various satellite servicing functions, including inspection and debris removal. The Remora mission serves as a proof of concept for the technology that will be utilized in these future missions.
Bennett stated, “This was a great proof point that we can take in signals from external sensors and guide Mira with them,” highlighting the potential for even closer approaches in future operations. Both companies expressed interest in pursuing further collaborations, with Impulse Space planning additional missions that could leverage the capabilities demonstrated in Remora.
Criticism & Opposition
While the mission was largely celebrated, some industry observers have raised concerns regarding the reliance on a single camera for such critical operations. Critics argue that this approach may not be sufficient for more complex missions requiring higher precision and reliability.
Official Statements
In their joint announcement, both companies described the Remora mission as a success. Eric Romo remarked, “We’re excited about the opportunity to demonstrate it,” while Trevor Bennett noted, “Proving this capability is a major milestone for Starfish.”
What's Next
Looking ahead, Starfish Space is preparing for its first full-scale Otter missions, scheduled for 2026-2027, while Impulse Space is pursuing a partnership with Anduril for a high-precision RPO mission in geosynchronous Earth orbit in 2026. Both companies are optimistic about the future of autonomous spacecraft operations and the potential for expanded applications in satellite servicing and beyond.
