A NASA-backed spacecraft built to inspect dead satellites has itself become a piece of space debris. Starfish Space said on November 3 that its Otter 24C spacecraft is unrecoverable after a software error silenced its radio, ending a $15 million mission barely a month after launch.
The Tukwila, Washington-based startup announced the loss in a LinkedIn post, and NASA confirmed it the same day. The spacecraft, part of a mission called SSPICY — the Small Spacecraft Propulsion and Inspection Capability — had been sent to approach and inspect inoperable American satellites in low Earth orbit. Instead, it joined the very graveyard it was sent to study.
A Month in Orbit, Then Silence
Otter 24C launched on October 1, 2026, aboard a SpaceX Falcon 9 rocket on the Transporter-18 rideshare mission. According to Starfish, the early days went well: the oven-sized spacecraft deployed successfully, established two-way contact with the ground, and downlinked significant telemetry while engineers commanded it through its first operations.
The trouble came during commissioning, the careful phase after launch when a spacecraft's systems are switched on and calibrated in sequence. During that process, contact with Otter 24C was lost — and this time, it never came back.
An investigation traced the failure to the spacecraft's fault protection system, the onboard software designed to detect problems and respond by restarting or shutting down equipment. According to Starfish, an error in fault protection software on the satellite bus, provided by Astro Digital, turned the radio off and prevented engineers from re-establishing communications. Because the spacecraft could not receive commands, no fix could be uploaded.
"Starfish, NASA and Astro Digital determined that the spacecraft was unrecoverable," the company said. NASA said the same in its own statement on November 3, noting that Starfish has not been able to re-establish two-way communication and that troubleshooting and analysis by both NASA and Starfish revealed the fault protection issue keeping the radio erroneously switched off.
What SSPICY Was Supposed to Do
SSPICY was the first launch and deployment of Starfish's full-scale Otter spacecraft, and the first time the company's navigation and propulsion technologies were integrated into a single vehicle. Its job was to approach multiple defunct U.S. satellites in low Earth orbit and inspect them at close range, gathering data that could inform future missions to deorbit or service dead spacecraft.
The mission was funded by NASA's Advanced Research and Technology Division, within the agency's Research and Technology Mission Directorate, through its Small Business Innovation Research program. NASA invested $15 million in the demonstration, part of a broader push to test commercial capabilities that could help manage the growing population of dead satellites and debris circling the planet.
The irony was not lost on space watchers. As one trade publication put it, Otter 24C "has joined the graveyard it was sent to inspect." The spacecraft itself is now an inert object in low Earth orbit, one more item on the list of things future cleanup missions may one day have to deal with.
A Second On-Orbit Setback
The loss is the second on-orbit mishap for Starfish, and according to reports, both involved faulty third-party hardware. In 2023, the company's first satellite, Otter Pup 1, was released into a violent tumble after its ride to orbit suffered an anomaly, spinning at 330 degrees per second. Starfish engineers eventually found a way to reverse the spin after six weeks, salvaging that demonstration.
This time there was no recovery. A spacecraft that cannot hear commands cannot be rescued, no matter how clever the engineering on the ground.
The setback also lands as a second blow for NASA's in-space servicing and assembly work, known as ISAM. Around the same time, an earlier mission with Katalyst Space that attempted to boost the aging Neil Gehrels Swift Observatory failed, and Swift itself was expected to burn up in Earth's atmosphere this week after 22 years in orbit.
What Starfish Says Comes Next
Starfish struck a determined tone in its announcement. "Developing new capabilities in space requires taking on difficult challenges, learning quickly and applying those lessons to what comes next," the company said. "The work completed through Otter 24C will directly contribute to the success of future Otter missions as Starfish continues developing the technologies and operations required to make satellite servicing a routine capability in orbit."
The company said it is working closely with Astro Digital to fix the fault protection system and update testing procedures for future Otter spacecraft, and that it is implementing fixes to the bus to avoid similar failure modes. Starfish and NASA are also exploring whether some of SSPICY's objectives can be fulfilled through other Starfish missions.
NASA sounded a similar note. Greg Stover, director of the Advanced Research and Technology Division at NASA Headquarters, said "commercial capabilities like Starfish's are critical for a competitive U.S. space economy and strong American leadership in low Earth orbit." He added that technology demonstrations allow the agency to test new systems quickly, learn from their performance, and iterate. "NASA will continue taking on bold challenges in close collaboration with our industry partners," Stover said.
What This Means
The failure matters beyond one startup's bad month. Low Earth orbit is getting crowded, and dead satellites are a genuine hazard: they can collide with working spacecraft and generate clouds of debris that threaten everything else in their path. NASA's bet on SSPICY was that commercial companies could learn to approach, inspect, and eventually remove these objects — a capability no one has yet made routine.
Losing the demonstrator to a software bug does not disprove that bet, but it does show how unforgiving the business is. A single fault-protection error, in code meant to protect the spacecraft, became the thing that killed it. And because the failure mode removed the radio, the usual safety net — diagnosing the problem from the ground and patching it — was gone too.
For the wider U.S. space industry, the timing is awkward. Starfish raised more than $100 million in a funding round in April 2026, according to reports, and holds government work including a satellite disposal job for the Pentagon's Space Development Agency. Investors and agencies will now want to see that the fault protection fix is real before the next Otter flies.
What Happens Next
Several other Otter missions remain on the company's manifest, according to GeekWire: the Space Development Agency disposal job, two commercial satellite servicing missions in geostationary orbit, and two servicing missions for the U.S. Space Force. A separate Otter is also due to be delivered to the military in 2028 under a Space Force contract, according to reports.
Closer at hand, Starfish's smaller Otter Pup 2 prototype, launched in 2025, is still working. Last week the company shared imagery of the prototype maneuvering to within about 33 meters of Gilmour Space's ElaraSat satellite, and it says a docking attempt is coming — which it has described as a chance to make history.
That success, if it comes, would soften the SSPICY blow and show that the core rendezvous technology works even when a full-scale mission does not. For now, though, Otter 24C circles silently overhead: a $15 million lesson in how a tiny software error can end a mission, and a reminder that in orbit, the spacecraft sent to clean up the junk can become junk itself.
