Founded in 2022, AstroForge has launched two prototype spacecraft, both of which suffered anomalies that prevented them from achieving most of their objectives. In 2025, its Odin spacecraft was launched into deep space, but the company could not gain control due to a shortage of large antennas on Earth and limited communication windows. The experience spurred AstroForge to consider putting sufficient intelligence onboard the spacecraft to solve its own problems.
"Would that have been recoverable with all the data on the spacecraft? I don't know, but I can tell you nothing onboard tried it, and I would love something onboard to try if the spacecraft is unrecoverable at launch," said Matthew Gialich, AstroForge's co-founder and CEO.
The company has developed an autonomous control stack called "Solo," a transformer-based model made in-house. Armand Awad, head of flight software, said the company decided to leverage advances in transformer models driven by frontier labs. The stack includes traditional control algorithms, models trained on test data for specific subsystems like power generation or navigation, and an overall intelligence layer trained on about 2,500 sensors in the spacecraft.
"I'm not saying I'm going to make general spacecraft autonomy or general autonomy for the world," Gialich said. "I'm making a constrained autonomy at a very low sensor input, following the basic training of a transformer model."
In theory, the AI agent will perform tasks like anomaly resolution. Awad imagines it realizing it has lost track of its position in space, correlating a power anomaly to issues in its star tracker, and fixing the problem—"probably turning it on and off in this case."
Most spacecraft autonomy currently depends on traditional control algorithms due to concerns about the unreliability of neural networks. The first use of a neural network to control a satellite's positioning in orbit took place just last year, according to a paper on arXiv.
AstroForge's third vehicle, DeepSpace-2, is set to launch alongside Intuitive Machines' third moon mission, expected by the end of 2026. Solo will fly in "shadow mode" on that vehicle, allowing engineers to test it before the Autonomy-1 mission. Gialich noted the trade-off: building a ground network of antennas would cost around $200 million, versus attempting to reduce communication dependency with an AI model.
"The trade for me is: Do I go build my own ground network, which is going to cost [around] $200 million to put up five dishes around the world and then do operations on it, or do I try to remove it with a model?" he said.
