A Transformer Model Named Solo Will Pilot AstroForge's Next Deep Space Craft

Matt Gialich and José Acain have raised $55 million to do something no one has ever done: mine an asteroid. Their company, AstroForge, is not building a better SaaS dashboard. It is building autonomous spacecraft, developing a proprietary refinery for spaceborne metals, and betting that a transformer-based AI model can pilot the whole operation from millions of miles away [TechCrunch, September 2026]. The total disclosed capital, confirmed across multiple sources, sits at $55 million [Dealroom.co, retrieved 2026] [O'Melveny, retrieved 2026]. The lead investor on the latest Series A is Nova Threshold [Tracxn, retrieved 2026].

For a fintech reporter, the numbers are familiar. The ambition is not. This is a capital-intensive, multi-year venture with hardware in orbit and a revenue event that is, by definition, extraterrestrial. The bet rests on a stack of technologies, but the most immediate proof point is a spacecraft called DeepSpace-2, scheduled for launch in the second half of 2026 [AstroForge - Wikipedia, retrieved 2026].

The stack: refinery, spacecraft, and an AI pilot

The company's plan unfolds in layers. First, identify near-Earth asteroids rich in platinum group metals (PGMs) [SBIR, retrieved 2026]. Second, extract and refine those materials in space. Third, return the valuable commodities to Earth. To get there, AstroForge is developing the entire chain.

Its first two prototype missions, Brokkr-1 and Odin, were critical learning tools. Brokkr-1, a 6U cubesat built with U.K. manufacturer OrbAstro, launched in 2023 to test material refinement technologies [Orbital Today, March 2025]. It re-entered Earth's atmosphere in early 2026 [Orbital Radar, retrieved 2026]. The Odin spacecraft launched in 2025 but encountered communications problems that prevented the team from regaining control [Superpower Daily, retrieved 2026]. Both spacecraft, the company acknowledges, suffered anomalies that killed most of their mission objectives [TechCrunch, September 2026].

The response is a redesigned spacecraft and a new pilot. DeepSpace-2 incorporates lessons from those earlier missions [Aerospace America, retrieved 2026]. More notably, it will be commanded by "Solo," an in-house, transformer-based AI model. Solo sits above traditional deterministic flight software and is trained on data from roughly 2,500 spacecraft sensors [Progressive Robot, September 2026]. The goal is autonomous operation without human intervention, a necessity for missions where communication delays render real-time control impossible.

Why Nova Threshold wrote the check

A $55 million venture-scale round for a pre-revenue space mining company demands a specific kind of conviction. The lead, Nova Threshold, is joined by a syndicate that includes 776, Initialized Capital, Caladan, Uncorrelated Ventures, and Y Combinator, where AstroForge was part of the Winter 2022 batch [Y Combinator, Winter 2022].

The investor case appears to hinge on three interconnected bets:

• The team's pedigree. Founders Matt Gialich and José Acain bring more than a decade of combined aerospace experience from NASA, SpaceX, and Virgin Orbit [Y Combinator, Winter 2022]. Gialich led software and guidance teams at Virgin, while Acain is a former SpaceX engineer [Business Insider Africa, retrieved 2026].
• The regulatory and cost moat. Asteroid mining operates in a nascent legal framework, and the sheer technical complexity creates a high barrier to entry. First-mover advantage in securing rights and proving capability could be significant.
• The commodity play. Platinum group metals are critical for everything from catalytic converters to hydrogen fuel cells. Establishing a supply chain independent of terrestrial mining politics and environmental constraints is a long-term, high-value proposition.

The hard reset after Odin

The path is not without visible friction. The anomalies on the first two missions are a matter of public record [TechCrunch, September 2026]. For a company whose product is reliable spacecraft, these were not minor bugs. The Odin mission, intended as the inaugural deep-space prospector, failed to establish stable communications after launch [AstroForge, retrieved 2026].

AstroForge's answer is a technical and operational overhaul. The DeepSpace-2 spacecraft has been physically redesigned to prevent a repeat of the issues that plagued Odin [Aerospace America, retrieved 2026]. More fundamentally, the company is shifting strategy from direct human oversight to AI autonomy with Solo. This addresses the core vulnerability exposed by the communication failure: a deep-space craft must be able to think for itself.

The company has also scaled its team aggressively to execute this complex roadmap. From a headcount of 10 cited in earlier Y Combinator materials, the team has grown to an estimated 75 people as of mid-2026 [Tracxn, retrieved 2026] [TipRanks.com, retrieved 2026]. This growth underscores the operational ramp required to build, test, and fly increasingly sophisticated spacecraft.

A 2027 mission with Stoke and NASA

The next major milestone is not a revenue number. It is a launch date. AstroForge has a mission on the books for 2027, planning to fly an autonomous spacecraft on the first rocket launched by Stoke Space [TechCrunch, September 2026]. This mission is expected to have NASA support and will gather scientific data about the Sun, providing an additional validation path beyond the core mining objective.

Success would mean Solo successfully navigating a deep-space trajectory, a feat that would instantly reposition AstroForge from a ambitious startup to a demonstrated leader in autonomous space operations. Failure would raise serious questions about the viability of its full-stack approach within a competitive funding environment.

The financial runway provided by the $55 million is now being deployed against this timeline. The company is hiring for critical roles like Senior Embedded Software Engineer and Electrical Engineer, with salary bands indicating a serious hunt for top technical talent [Y Combinator]. The clock is ticking, but the capital is in place.

For investors like Nova Threshold and 776, the bet is clear. They are funding the assembly of a space-bound refinery and the AI pilot to run it, betting that Gialich and Acain can translate their SpaceX and Virgin Orbit pedigrees into a functioning extraction business. The $40 million Series A, led by Nova Threshold and closed in 2024, bought the team the time and resources for this hard reset [SpaceNews, retrieved 2026]. The question for the next twelve months is whether DeepSpace-2 can leave earlier anomalies firmly in its wake, proving that a transformer model can succeed where radio signals failed.
