We love to pat ourselves on the back for smartphones and the internet. But if an alien species graded our technological progress right now, we would barely register on the chart.
In a recent sit-down with his engineering directors, SpaceX CEO Elon Musk brought up a concept called the Kardashev scale. It is a metric used by astrophysicists to measure how advanced a civilization is based entirely on its energy consumption. A Type 1 civilization controls all the energy of its home planet. Type 2 harnesses the entire energy output of its local star. Type 3 controls its galaxy.
Where are we? We are practically nowhere.
Earth only catches a half-billionth of the sun's output. Of that tiny sliver, the vast majority hits the oceans or uninhabitable land. Humanity is currently utilizing less than a trillionth of the sun's total power. To even reach a single meaningful percent on that cosmic scale, we have to leave the planet.
That is exactly what SpaceX is gearing up to do, and their blueprint is staggering.
The bottleneck for building massive energy structures in space comes down to three things. You need to get enough mass off the Earth, you need a way to generate the power, and you need to secure enough computing chips to make the whole thing worthwhile.
Getting mass to orbit is the entire reason Starship exists. Before this vehicle, rockets were thrown away after one use. It is like trashing a commercial airliner after a single flight from New York to London. Starship changes the math through full and rapid reusability. The rocket goes up, the booster comes down, gets caught by a giant mechanical tower, and is prepped to fly again. The company wants to move from putting thousands of tons into orbit to millions of tons.
But what exactly are they putting up there? This is where the strategy takes a wild turn.
SpaceX is not just launching internet routers anymore. They are looking directly at artificial intelligence. Training AI requires massive data centers that consume mind-boggling amounts of electricity and generate extreme heat. On Earth, cooling these facilities is a massive physical and environmental headache.
In space, cooling is actually a lot simpler. You just radiate the heat out into the cold vacuum.
The company has designed a new class of satellite built specifically to act as an orbital data center. These are massive structures with 70-meter wingspans, loaded with giant solar arrays and deployable liquid radiators. They will capture pure, unfiltered solar energy to power cutting-edge AI chips. The satellites will then link back to Earth and to each other using laser communication.
To pull this off, SpaceX is building a colossal factory in Texas that they are calling a Terafab. The immediate goal is to crank out enough of these satellites to reach one terawatt of computing power in space within a few years. That alone is a massive leap in human energy consumption.
Yet the ultimate plan goes even further.
Launching millions of tons from Earth is always going to be expensive because of our deep gravity well and thick atmosphere. The moon does not have those problems.
The long-term vision involves setting up a manufacturing base on the lunar surface. By using local materials to build solar panels and radiators, SpaceX could manufacture these AI satellites directly on the moon. Then, instead of launching them with chemical rockets, they would use an electromagnetic track to literally shoot the hardware into space.
It sounds exactly like science fiction. But the factory is already under construction, the chips are being sourced, and the rockets are already flying. If this massive infrastructure play works, humanity might finally get a real score on the cosmic scale.
