"Starfish Space's Otter Is About to Get Closer to Dead Satellites Than Anyone Has"

Seven years after founding Starfish Space, Trevor Bennett and Austin Link are finally watching their first full-size Otter spacecraft prepare to fly. The two engineers left Blue Origin in October 2019 with a conviction that the busiest region of space — low-Earth orbit — was about to need a new kind of janitorial and repair service, and they set out to build it. A global pandemic shut the world down within months, but the company persisted, and this fall the ~350 kg spacecraft, roughly the size of a large washing machine, will ride a Falcon 9 Transporter mission to orbit on a demonstration flight for NASA. It's a milestone worth more than a headline, because it marks a genuine shift in how humanity treats the stuff it has already launched.

The immediate job is called SSPICY — short for Small Spacecraft Propulsion and Inspection Capability — and it is quietly historic. NASA is paying Starfish $15 million for the mission, and it's the first time the agency has funded a commercial orbital-debris inspection. Otter will fly up to several defunct, US-owned satellites and approach within hundreds of meters to measure their spin rates and overall condition. On the surface that sounds modest; in practice, autonomously sidling up to a tumbling, uncooperative object in orbit and holding a stable, safe distance is one of the hardest maneuvers in spaceflight.

That's the first thing worth appreciating here. For decades, the way we "dealt" with orbital debris was to track it from the ground — cataloging objects with radar and telescopes and maneuvering around the biggest threats when a collision looked possible. Otter represents the moment we stop just watching the problem and start reaching out to touch it. Actually visiting a dead satellite to learn how it's spinning and what shape it's in is the necessary first step before you can capture it, de-orbit it, refuel it, or repair it. The SSPICY mission is, in effect, the proof that inspection can become a routine, commercial service rather than a one-off engineering experiment.

There's also a hard-nosed business logic underneath the poetry. Bennett and Link identified two markets from the start: extending the life of large satellites in geostationary orbit, and managing the swelling constellations in low-Earth orbit. The GEO side is where the money is most obvious — a communications satellite can cost hundreds of millions of dollars to build and launch, so buying a few extra years of service life for a fraction of that cost is a straightforwardly good deal. Otter's software-first approach, with a spacecraft bus purchased from Astro Digital rather than built in-house, means the company's real product is the guidance, navigation, and control capability that makes precise rendezvous and docking possible. In an industry historically defined by expensive bespoke hardware, Starfish is betting that the valuable part is the software.

That bet has already survived real failure, which is worth noting. The company's first demonstration, Otter Pup 1, launched in 2023 but was ejected from its orbital transfer vehicle prematurely at a spin rate of 330 degrees per second. The team spent weeks recovering the spacecraft before one of its thrusters eventually failed. Rather than folding, they iterated: Otter Pup 2 launched in 2025 and has flown to within a kilometer of a target, with docking expected in the coming months. Starfish also partnered with Impulse Space to fly its software on the Mira spacecraft after that vehicle finished its primary mission, demonstrating autonomous rendezvous with a lightweight camera and closed-loop control. This test-and-learn cadence is the same philosophy that transformed the launch industry, now being applied one layer up the stack.

The scale of the operation is also striking. Starfish has kept itself lean — roughly 120 employees and about $150 million raised over seven years — while putting five more Otters into production for missions that will showcase docking, de-orbiting, and life-extension capabilities. That restraint, in an era of space startups that often raise and spend aggressively, suggests a company building toward a durable service business rather than a single dramatic demo. The fleet approach matters: one inspection is a stunt, but a lineup of reusable servicing vehicles is an industry.

Stepping back, Otter's launch points at something broader about where space is going. The past decade was dominated by the launch revolution — the spectacular business of getting mass into orbit cheaply and often. The next decade increasingly looks like the logistics layer that follows any transportation boom: the maintenance, refueling, removal, and inspection services that keep everything already up there working. Launch only gets you to the frontier; servicing is what makes living there sustainable. Starfish is one of the earliest, most focused companies trying to become the AAA roadside service of Earth orbit.

There's a fitting symmetry in Bennett's own framing of the moment. "There is always a tension that comes with seeing the first of anything fly," he told Ars Technica's Eric Berger, balancing nervousness with "huge amounts of excitement." That tension is earned — seven years of building toward a single first impression. If Otter performs as designed, it won't just validate one company's spacecraft; it will quietly open a new commercial category, and give the world its first close look at the debris problem it can no longer afford to ignore.

For more on the orbital-debris challenge Otter is designed to tackle, NASA's Orbital Debris Program Office and the European Space Agency's Space Debris Office both maintain authoritative data on the growing population of objects in orbit.
