The gas station is on the Moon. Starpath is building the robots, the refinery, and the tanks to fill it - so a rocket never has to haul its heaviest fuel out of Earth's gravity again.
Somewhere in a crater that has not seen sunlight in two billion years, a machine is supposed to be digging. It is dark, it is roughly 400 degrees below zero, and the dirt is laced with frozen water older than the oceans. That crater does not exist as a Starpath job site yet - but everything the company does in a warehouse in Hawthorne, California is aimed squarely at it. The pitch is not "let's go to the Moon." Everyone says that. Starpath's pitch is quieter and stranger: let's build the fuel depot first.
Rockets are, by weight, mostly oxygen. The oxidizer is the heavy, expensive, unglamorous majority of what sits in a tank at launch. So Starpath asked the obvious question that somehow nobody had turned into a company: what if you didn't bring it? What if you made it where the rockets actually need it - on the surface of another world?
CAPTION - A refinery that doesn't exist yet, on a world we've barely touched, for customers who haven't landed. This is what conviction looks like before the hardware ships.
That was CEO Saurav Shroff's shorthand when Starpath came out of stealth in 2023 - a joke with a spreadsheet behind it. Water is most of a rocket's fuel mass. Split water and you get hydrogen and oxygen; the oxygen is the oxidizer that makes combustion possible. If Starpath can harvest lunar ice and refine it into liquid oxygen on-site, a lander only needs to arrive with the lighter half of the equation. The Moon supplies the rest.
The founders are not tourists to this problem. Shroff and co-founder Mihir Gondhalekar both did stints at SpaceX before starting Starpath in mid-2022, along with co-founder Jason Zang. Their resumes are short on years and long on ambition - a fact critics noted and investors evidently forgave.
Because the logic holds. Every Starship that lands on the Moon would burn an estimated 100 to 300 tons of oxygen just to leave again. Blue Origin's Blue Moon lander needs tens of tons per flight. Both companies hold NASA contracts to be there before the decade ends. That is a market with a delivery address and no supplier - the kind of gap founders dream about.
So Starpath is building toward the least romantic, most decisive piece of infrastructure in spaceflight: the propellant supply chain. Not the rocket. The fuel the rocket runs on, made a quarter-million miles from the nearest refinery.
It is infrastructure thinking applied to the solar system. The colony, the base, the flag - those come later and get the headlines. The tank farm comes first and gets the invoices.
Starpath's architecture is a four-part loop meant to run autonomously in one of the harshest environments a human machine has ever operated in.
A fleet of autonomous rovers excavates water-rich regolith from permanently shadowed south-pole craters.
On-site plants purify the material into water, then electrolyze it into hydrogen and oxygen.
Liquid oxygen is chilled and held in cryogenic tanks - including underground Teflon-lined containers.
Landers and Starship-class vehicles top off with locally made LOX and head deeper into the system.
Power comes from a large deployable solar array - built with partner Solestial - staged on peaks of near-eternal light at the pole, a few kilometers from craters that never see the Sun at all. It is a study in contradictions: the brightest and darkest places on the Moon, working the same shift.
Autonomous excavators designed to dig regolith in the cold and dark of the lunar south pole - no daylight, no operators, no second chances.
Processing plants that turn dirt into water and split water into hydrogen and oxygen. The chemistry is old; doing it on the Moon is not.
Cryogenic storage - reportedly including underground Teflon-lined tanks - to keep liquid oxygen cold and ready for the next customer.
A large power array staged on sunlit peaks, developed with Solestial, to run mining and refining around the clock.

Rounded out the founding trio that started Starpath in Hawthorne in mid-2022.
Led by Hummingbird Ventures and Valhalla Ventures, as the company emerged from stealth with its full water-harvesting architecture.
Awarded through NASA's Break the Ice Lunar Challenge - a public bet on Starpath's ISRU approach.
Co-led by 8VC and Fusion Fund, with Day One Ventures, Balerion Space, and Indicator Ventures participating. Reported ~10 full-time staff at close, with plans to scale fast.
CAPTION - Investors rarely fund a product that can't be delivered on Earth. Starpath's tank of liquid oxygen won't exist until it exists on the Moon. They wrote the checks anyway.
Starpath's customers are the vehicles that need oxidizer on the Moon and don't want to fly it up from Earth. SpaceX's Starship and Blue Origin's Blue Moon are the marquee names - both NASA-contracted, both scheduled to be on the lunar surface this decade. The company designed its economics to serve small water buyers and large programs alike.
The competition? A young cohort of off-world resource ventures - Interlune, AstroForge, OffWorld among them - and, more stubbornly, the status quo of simply launching propellant from Earth. Starpath's job is to make the status quo look expensive.
Back to that dark crater at the bottom of the Moon. Today it is empty - just ice and silence and cold that predates our species. Starpath's whole company is a wager that it won't stay that way: that one day a rover will roll in, dig, and hand off dirt to a refinery that turns two-billion-year-old water into the breath a rocket needs to fly again.
If they pull it off, the crater stops being the edge of the map and becomes a waypoint - the first stop where a ship bound for Mars tops off its tanks. Not a destination. A gas station. Starpath is fine with that. The most important infrastructure is the kind nobody thinks about, right up until they can't imagine doing without it.
