Advances in synthetic intelligence are driving surging demand for data centers. But these warehouse-like services, containing computer systems that course of and retailer data, require numerous land and big quantities of vitality, producing important carbon dioxide (CO2) emissions.
Data middle energy demand will enhance 165% by 2030, in accordance to Goldman Sachs. Some data centers use renewables, and others are being constructed with renewable energy generation on-site, however clear vitality sources like photo voltaic and wind farms require bodily space, as does data middle infrastructure.
Now, some are trying to put data centers into space, bypassing the issue of discovering obtainable land. Space additionally provides better access to solar energy, with out the cloud cowl, the darkness of nighttime or the seasonality of Earth.
In Europe, the ASCEND challenge goals to reveal the feasibility of space-based data centers for lowering CO2 emissions.
Last yr, France-based Thales Alenia Space, which led a European Commission-funded study into the feasibility of ASCEND, discovered that sending data centers to space to make the most of steady photo voltaic vitality might supply “a more eco-friendly and sovereign solution for hosting and processing data.” But that will be contingent on technological developments in a number of areas, mentioned Xavier Roser of Thales Alenia Space.
While the whole emissions from rocket launches are at the moment solely a fraction of these from the aviation business, rockets launch pollution at increased altitudes, the place they last more.
The ASCEND research estimated that for space data centers to successfully scale back carbon emissions in contrast to their terrestrial counterparts would require the event of a launcher that emits 10 instances much less carbon over its lifecycle than present ones. It’s not clear when or if such a rocket could also be in growth. SpaceX, which has revolutionized the price of rockets with its fleet of Falcon launch automobiles, has not revealed any plans to debut a extra environmentally pleasant rocket design.

Abu Dhabi-based startup Madari Space has collaborated with an industrial accelerator program run by Thales Alenia Space, and is one in all a handful of companies which can be launching small computing elements into orbit as technical demonstrations.
Madari founder and CEO Shareef Al Romaithi, who can be a pilot for Etihad Airways, mentioned space-based data centers may benefit a wide range of clients, together with these with Earth commentary satellites. He mentioned storing and processing their uncooked commentary data in space can scale back lag time in anlayzing their findings, and “allow them to make informed decisions in a timely manner,”
He hopes to finally deploy a constellation of data satellites into orbit. While that purpose is a approach off, Madari’s first mission, scheduled for 2026, will send a payload concerning the dimension of a toaster oven — consisting of data storage and data processing elements — into orbit aboard an Emirati satellite tv for pc, a part of the UN Office for Outer Space Affairs (UNOOSA)’s Access to Space for All Initiative.
Others have already carried out launches. In May, China launched 12 satellites for a space-based computing constellation — the primary of a proposed 2,800-satellite fleet to course of data in space.
Al Romaithi says that must be a wakeup name to take into account space a viable location for data centers. “It is a reality that’s happening,” he mentioned.
Lonestar Data Holdings, a Florida-based agency, mentioned in March that it successfully tested a small data middle on the moon, regardless of the system landing on its side and powering down early.
In November, Starcloud — a Washington state-based startup — will launch a satellite tv for pc geared up with a Nvidia H100 graphics processing unit (GPU). The firm instructed NCS by way of e-mail that it’ll set a report for essentially the most highly effective in-orbit compute energy.
“My view is that in 10 years’ time, almost all new data centers will be being built in space, purely because of the constraints we are facing on building new energy projects terrestrially,” Philip Johnston, its CEO, mentioned within the e-mail. The most important challenges to overcome first are dissipating giant quantities of warmth in a vacuum and making the chips work in a excessive radiation surroundings, he added.
Still, it’s very early days for the sector — and an enormous leap to launch data centers sufficiently big to supply an alternate to these on Earth. Cost might be key, with launch prices depending on the burden of the payload.
Lonestar has signed a $120 million deal with spacecraft provider Sidus to construct and supply on-orbit assist for six data-storage satellites. It plans to launch the primary in 2027 — a 15-petabyte system working from the Earth-moon Lagrange level L1, some 60,000 kilometers from the moon. The subsequent 5 satellites will every double in storage capability, whereas conserving the identical weight and vitality necessities, the corporate says.
Each will share a trip with bigger satellites aboard a SpaceX Falcon, making up round 15% of the payload mass. That might value within the area of $10 million per launch, for a fraction of the storage of many terrestrial data centers.
But some specialists are skeptical concerning the economics of data centers in space. “To do a cost effective, true, objective analysis of it, it doesn’t really stand up to scrutiny,” mentioned Quentin A. Parker, the director of the Laboratory for Space Research on the University of Hong Kong (HKU). “The terrestrial solutions are still there, and they’re still probably a lot cheaper than trying to put anything into space,” he added. “Putting them into space has all sorts of problems associated with it.”
While advocates declare that storing data in space might present safety from data centers being attacked, or broken due to pure disasters, Parker factors out that space brings its personal dangers, together with radiation, space debris, and likewise the implications of sending extra human-made objects into space with no resolution for cleansing them up.
Experts have been elevating alarm bells concerning the growing quantity of human-made junk left in space; they warn {that a} collision might take down space-based applied sciences that energy our on a regular basis lives.
Others have identified that sustaining and repairing data centers in space might pose a major challenge, whereas space climate, equivalent to photo voltaic flares, might disrupt companies. And various nations are reportedly developing “counterspace technologies,” equivalent to jamming programs that may be focused at satellites.
Proponents of space-based data centers could also be “overselling the advantages and significantly underselling the major drawbacks,” mentioned Parker.
But for Al Romaithi, trying off-planet is a necessity. “It is worth overcoming these challenges because the alternative is technological stagnation,” he mentioned. “We will reach a point where we are exhausting our resources just to run data centers.”
