Researchers did not connect ChatGPT to a real spaceship. They tested language-model agents controlling spacecraft simulated in the Kerbal Space Program (KSP) game engine—and their team finished second in a spacecraft-control competition. The result is a notable demonstration in a simulation, not evidence that current ChatGPT models can safely pilot operational spacecraft.

What did the researchers actually test?

Alejandro Carrasco, Victor Rodriguez-Fernandez, and Richard Linares studied large language models as autonomous operators in the Kerbal Space Program Differential Games (KSPDG) challenge. Their paper, “Large language models as autonomous spacecraft operators in Kerbal Space Program,” was published in Advances in Space Research on September 15, 2025. An earlier preprint was submitted to arXiv on May 26, 2025. Read the published study or view the arXiv preprint.

The models included GPT-3.5 and LLaMA—not an evaluation of today’s consumer ChatGPT models. In the challenge, agents faced simulated, non-cooperative space-operation tasks. Examples include pursuing an evasive satellite and conducting proximity operations involving multiple satellites. MIT Lincoln Laboratory’s challenge description lists measures such as mission completion time, fuel use, and relative distance.

How did a language model control a spacecraft in the simulation?

The system translated the simulated vehicle’s state and its goal into text, sent that prompt to a language model, and converted the model’s response into actions for the simulated vehicle. The paper examined different ways to guide or adapt the models, including prompt engineering, few-shot prompting, chain-of-thought prompting, and fine-tuning.

The study’s opening prompt, as reproduced by Live Science and also reported by Futurism, began: “You operate as an autonomous agent controlling a pursuit spacecraft.” Futurism’s report gives that prompt in context. The wording describes an instruction to an agent; it does not mean a real spacecraft was connected to ChatGPT.

What were the results—and what do the failure rates mean?

The authors report that their LLM-based team ranked second in the KSPDG competition. That is a competition result in a particular simulated environment, not a general ranking of chatbots or a measure of flight readiness.

The paper also reports that performance varied with the experimental setup. In its fine-tuning comparison, the baseline GPT setup had a 36.8% failure rate, while a simple fine-tuning setup recorded 0.0% in that table. In a separate chain-of-thought comparison, the baseline GPT agent failed in 37.5% of runs, while the chain-of-thought setup recorded 0.00% failures. These percentages belong to their respective experimental comparisons; they are not general reliability rates for GPT or ChatGPT.

Those results illustrate why the method matters: prompting and training choices affected outcomes. The study considered measures that included failures, closest approach, and response latency, and results from different test conditions should not be read as one direct head-to-head contest.

Does this show ChatGPT could pilot a real spacecraft?

No. The experiment tested agents in a game-based spacecraft simulation. It did not test a live spacecraft, establish real-world reliability, qualify a system for flight, or demonstrate that it is safe to hand operational control to a language model. Strong performance in a constrained simulator is a research result; it does not by itself show how a system would handle the physical, communications, timing, and safety demands of an actual mission.

The accurate takeaway is narrower but still interesting: researchers built a pipeline that let language-model agents interpret text descriptions of simulated spacecraft states and goals, then issue actions in a competition environment. Their second-place finish shows promise for further study of language models in simulated space-operation tasks—not that ChatGPT is ready to fly a spaceship.
