SpaceX has put Grok to work on one of aerospace manufacturing’s least glamorous and most consequential jobs: finding stray junk inside rocket parts.
The company says xAI’s model now flags foreign object debris in borescope footage with 99.9% accuracy. Human inspectors doing the same task land at approximately 94%. That gap is a big deal when a single missed fragment can end a mission.
What SpaceX actually deployed
Kiko Dontchev, SpaceX’s Vice President of Launch, announced the deployment on November 9, 2026. Dontchev has spent 16 years at the company. He framed the rollout as a meaningful boost to engineering speed.
The task involves a borescope, essentially a thin camera on a flexible tube. Technicians snake it into tight internal spaces in hardware that can’t easily be opened up. The resulting video then has to be reviewed for anything that shouldn’t be there.
That “anything” is what the industry calls foreign object debris, or FOD. Think metal shavings left over from machining, or a fastener that ended up somewhere it was never meant to go. Small items, large consequences.
Under the new setup, the work is split. Humans still physically insert and steer the borescope. Grok watches the footage and independently flags anything that looks like debris.
SpaceX says this hybrid approach lets inspections move faster than the traditional method. The accuracy numbers suggest it isn’t trading quality for speed to get there.

More than one inspection line
Debris detection wasn’t the only AI use case Dontchev highlighted. SpaceX also shared that it has automated visual checks on Starlink hardware.
Those inspections previously took hours or days. They now take seconds or minutes, according to the company.
The Grok deployment follows SpaceX’s acquisition of xAI earlier in 2026. Owning the AI developer gives SpaceX a direct line into adapting the model for its own engineering workflows, rather than relying on an outside vendor’s priorities.
Why debris gets so much attention
Foreign object debris has been a known hazard in aerospace for a long time. NASA maintains established standards for preventing it during manufacturing, which tells you how seriously the field treats the problem.
The logic is simple. Rocket engines and spacecraft systems operate under extreme pressure, heat, and vibration. A loose shaving that would be harmless in a kitchen appliance can become a projectile or a blockage inside a turbopump.
Human inspection has always been the main defense. Reviewing borescope footage is repetitive, detail-heavy work, and people get tired. An accuracy rate of approximately 94% is respectable for a human doing a hard visual task. It is less comforting when you remember what the remaining misses could mean.
The pressure on inspection has only grown as SpaceX leans into rapid reuse. Programs like Starship depend on flying hardware again and again, with quick turnarounds between flights. Each turnaround is another round of checks.
What this means
That said, the structure SpaceX chose is worth noticing. Humans haven’t been removed from the loop. They still operate the equipment, and the AI acts as a highly attentive second set of eyes on the footage.
