Information centres are the spine of our digital infrastructure, supporting the whole lot from social media platforms to on-line buying and streaming companies. With the rise of synthetic intelligence (AI), cloud computing and the web of issues, the quantity of knowledge generated and processed day by day is extraordinarily massive, and the demand for information centres is continually rising.
Information centres, sadly, are massively vitality hungry – amongst a bunch of different environmental drawbacks. One doable answer is to construct them in area, and several other firms are engaged on making this a actuality. So how would this work, and is it actually going to occur?
Worldwide information centre demand is anticipated to rise at round 20% a 12 months over the following few years. Within the UK alone, Google, Microsoft and varied different US firms are collectively spending £20 billion to ramp up data-centre capability for AI up and down the nation.

But information centres constructed for high-performance computing and AI require far more energy than a typical facility. This generates much more warmth, which entails an extra substantial enhance in energy calls for for liquid cooling amenities.
In line with the Worldwide Power Company, information centres accounted for about 1 to 1.5% of worldwide vitality use in 2023, and this determine is anticipated to rise considerably within the years forward. Moreover, cooling techniques can exacerbate water shortages in some areas, whereas the rising e-waste generated from outdated tools can be a giant downside.
To try to deal with the vitality difficulty, data-centre corporations have been investing in renewable vitality sources like wind, photo voltaic and nuclear to scale back their carbon emissions. They’re additionally utilizing superior cooling applied sciences to make their information centres extra vitality environment friendly.
Even so, it’s nonetheless going to be a serious problem to roll out sufficient capability. Information centres require substantial bodily area and infrastructure, making growth each tough and dear.
A brand new frontier?
Because of this US firms like Lumen Orbit and the EU’s Ascend venture need to area as a substitute. Information centres past Earth’s ambiance would have entry to steady photo voltaic vitality and might be naturally cooled by the vacuum of area. Away from terrestrial points like planning permission, such amenities might be quickly deployed and expanded because the demand for extra information retains growing.
It might sound like one thing from a sci-fi novel, however this idea has been gaining extra consideration as area expertise has superior and the necessity for sustainable and scalable information centres has turn into obvious.
Lumen, which is predicated in Washington, not too long ago raised US$11 million (£8.9 million) in seed funding that can be used to construct a full-scale prototype in 2025. This facility can be geared in the direction of taking large quantities of uncooked information from different satellites, then utilizing AI to crunch it down for transmission to Earth, taking on a lot much less bandwidth than would in any other case be required.
In the meantime, Ascend accomplished an 18-month research final summer season that discovered that area information centres are economically viable and environmentally possible, offered the carbon emissions from launchers will be diminished by about tenfold. Backed by French defence big Thales, it goals to launch a gigawatt of capability into area over the following 25 years.
As with all too-good-to-be-true concepts, we must always actually be in little doubt in regards to the challenges concerned in these sorts of initiatives. It’s nonetheless vastly costly to launch payloads into orbit, even when firms like Elon Musk’s SpaceX have been making vital steps in decreasing the fee and growing the reliability of area launches. This may increasingly enormously restrict how rapidly area information centres might be launched.

There’s additionally the truth that the latency in communication between Earth and area impacts information transmission speeds. One other Musk firm, Starlink, has been making inroads into this difficulty with its burgeoning satellite tv for pc community, which Musk claims can be as quick as fibre broadband within the years forward.
Sustaining area information centres poses a serious problem. Area climate, equivalent to photo voltaic flares may disrupt operations, whereas collisions with particles are a serious fear – somewhat offsetting the truth that space-based information centres don’t need to worry earthquakes or floods. Superior shielding may shield towards issues like radiation and micrometeoroids, however it’s going to most likely solely accomplish that a lot – significantly as Earth’s orbit turns into ever extra crowded.
To repair broken amenities, advances in robotics and automation will after all assist, however distant upkeep might not have the ability to deal with all points. Sending restore crews stays a really complicated and dear affair, and although the falling price of area launches will once more assist right here, it’s nonetheless more likely to be an enormous burden for a number of a long time to come back. As well as, disposing of knowledge centre waste takes on a complete new stage of complexity off-planet.
So whereas there’s actually nice pleasure round this potential reply to our want for ever extra information centres, it’s clearly as complicated as it’s compelling. Hopefully, with critical effort into analysis and improvement – in addition to international collaboration – it will finally revolutionise the way in which we handle and course of information. Till then, with apologies, we’ll simply have to observe this area.
