Elon Musk has a expertise for bringing far-fetched concepts all the way down to earth. When phrase surfaced final month that two of the brand new era of house firms had been collaborating, he couldn’t assist however share his ideas, even when it was merely to make a easy level about SpaceX’s intentions to construct information facilities in orbit. There was no fanfare, no intensive rationalization, only a deadpan comment to scaling up present satellite tv for pc expertise. In a world the place the demand for processing energy is continually growing, that informal assertion despatched shockwaves throughout the IT group, drawing everybody’s consideration to that untapped useful resource – actually the void the place silicon meets daylight.
Rendezvous Robotics and Starcloud merely form of took off. Rendezvous, a brand new agency born out of MIT labs, creates modules that may be snapped collectively in zero gravity. Contemplate them flat tiles, every containing batteries, chips, and wiring, and stacked right into a rocket like a pack of taking part in playing cards. As soon as in orbit, electromagnets separate the tiles after which snap them again collectively, permitting them to assemble constructions which are far too massive for a human to deal with alone, or perhaps a robotic arm to function.

Starcloud brings imaginative and prescient and intelligence to the desk. They need to launch a satellite tv for pc in December geared up with an NVIDIA H100 information heart GPU, a beast of a part able to dealing with AI workloads. And that’s just the start: they intend to construct a complete information heart with 5 gigawatts of energy – sufficient to energy a decent-sized metropolis – in addition to 4 kilometer-wide photo voltaic panels and cooling sheets. For comparability, the Worldwide House Station’s photo voltaic arrays are the biggest ever constructed, but they solely cowl a fraction of its floor. Typical structure simply can’t scale that enormous; it could require a military of engineers or equipment to determine the association, and even then, the equations wouldn’t make up. That’s the place Rendezvous’ tiles are available, which have been layer by layer tailor-made to Starcloud’s enormous grid – all with out the necessity to manually flip a single bolt.

Musk didn’t take lengthy to supply his ideas on the state of affairs. “Merely scaling up Starlink V3 satellites, which have excessive pace laser hyperlinks would work…SpaceX shall be doing this,” he defined. Simply increase them up and use the laser connections to start out information flowing, and also you’ll have orbital compute farms. The current v2s can attain a most pace of 100 gigabits per second to Earth; the v3 is ten instances sooner, with much more mass and muscle. SpaceX is launching dozens of those at a time on their Starship, and testing signifies that they’ll have their dispensers sorted by mid-2026. Musk made it clear that that is merely an extension of the {hardware} that has already demonstrated its capacity to beam broadband web to the far reaches of the planet.
The demand for uncooked computing is quickly growing, and the Earth is starting to really feel the impression. These services eat electrical energy and water like there isn’t a tomorrow so as to keep cool, which naturally irritates populations involved concerning the environmental impression. Up in house, nevertheless, the solar shines brightly and gives limitless power without spending a dime – no want to fret about electrical energy payments – whereas the vacuum of house handles all warmth rejection by itself, eliminating the necessity for air-con or followers. Nevertheless, critics proceed to level out the excessive upfront expenditures and the troublesome engineering concerned, akin to safeguarding fragile circuits from extreme radiation and holding all that information synced throughout lengthy distances. However historical past has repeatedly demonstrated that when rockets develop into reasonably priced and dependable, folks start to take them significantly – see how Starlink reworked a constellation of 1000’s right into a money-making machine – so why not make the most of the identical construction to accommodate server racks as a substitute?

Eric Schmidt bought Relativity House in Could as a result of he envisions inserting servers in orbit, and Jeff Bezos, being Jeff Bezos, isn’t going to let anyone else take the lead on this one – he predicts gigawatt monsters floating round house in roughly 20 years. After which there’s Musk, with SpaceX’s unequaled logistics – he’s the one who could make all of it occur. Caleb Henry, who analyzes the house trade for Quilty House, says the indications are clear: when billionaires again a brand new thought, cash follows, and the principles are rewritten. Satellites have been shifting information round for years – telecom birds switch messages, whereas earthbound observers take footage and ship them again residence – however onboard intelligence has superior to the subsequent degree. A devoted information heart is the precise sport changer, processing inquiries within the void and returning responses sooner than any landline.
