Heat Is an Orbital Data Center’s Greatest Foe. These Tiles Dump It at the Source.
Sophia Space and Caltech want to fold the bulky parts of a space-based data center—solar cells and radiators—into all-in-one tiles with chips.
Every time you ask ChatGPT a question, computer chips in a massive data center whirl into action. In the blink of an eye, they ping back answers. Behind the scenes, though, AI data centers consume enormous amounts of electricity, heat, and water.
The AI boom is impacting communities. After welcoming 37 data centers, residents in Virginia’s Henrico County were hit with skyrocketing electrical bills. Schools and government buildings were asked to turn off lights, shut down computers, and avoid using space heaters to ease strain on the power grid and keep costs down.
Henrico isn’t alone. A growing backlash is prompting many states to consider legislation curbing new facilities. “No data center” signs have sprouted on lawns and alongside roads. Yet as AI demand continues to surge, so does the need for more computing power.
This has top AI companies looking skyward. Instead of routing requests to terrestrial data centers, future queries could be handled by thousands of solar-powered satellites orbiting above. The results would then be beamed back, with users none the wiser.
But there’s a major hurdle: heat.
Space’s frigid vacuum may seem like the perfect place to cool chips, but it’s not that simple. Lacking air and water to carry heat away, orbital data centers would have to use thermal radiation. Here, heat is converted into infrared energy and radiated into space, often requiring bulky hardware that adds weight, cost, and complexity.
With these challenges in mind, California Institute of Technology and Sophia Space, a California startup developing orbital computing, recently unveiled a patent for a chip cooling system designed to radiate heat into deep space. Called Sophia TILE, thousands of these chips could be linked to form large orbital data centers or organized into smaller, distributed clusters.
Powered by abundant sunlight, the chips could operate continuously without eating up Earth’s resources. The team hopes to test their vision by 2030.
“This patent reflects a different way of thinking about computer infrastructure in space,” said Leon Alkalai, founder and chief technology officer at Sophia Space, in a press release. “Instead of beaming down energy to Earth from orbit, we decided to consider putting computing in space and beam[ing] down data.”
The project joins a growing international push towards orbital computing. ADA Space, working with Zhejiang Lab, has already launched satellites for its Three-Body Computing Constellation and plans to expand into a much larger network. Meanwhile, US companies including SpaceX, Starcloud, and Blue Origin are seeking regulatory approval for constellations that could eventually grow to include up to a million AI-capable satellites.
Without doubt, the race is on.
Space CadetOrbital data centers would consist of high-performance computer chips housed in protective enclosures designed to withstand the harsh conditions of space. In orbit, they would collect uninterrupted solar power. In contrast, solar panels on Earth require batteries to store energy for use after sunset.
Solar power in space is hardly new. The International Space Station, satellites, and other spacecraft have long relied on solar panels. More recently, engineers have developed flexible, lightweight designs such as NASA’s Roll-Out Solar Arrays, which launch tightly rolled and unfurl in orbit.
AI, however, demands far more power. One long-standing idea for harvesting continuous solar power suggests we collect solar energy in space and beam it down to Earth. But that approach doesn’t completely appease the growing ire against data centers. They’d still consume energy on the ground and take up land and other resources. A newer idea flips the question. Rather than delivering energy to computers, why not bring computers nearer to the energy source?
The argument in favor of sending data centers skyward is growing stronger. A recent Gallup poll found roughly 70 percent of Americans oppose data centers in their backyard, while experts agree that meeting AI’s future energy demands on Earth alone will become increasingly unsustainable.
But while power is abundant in space, heat is the main problem. Without air or water to carry heat away, computers in space must rely on thermal radiation. That means adding large, heavy radiators to an already bulky, solar-powered setup. In space, weight is money, and scaling orbital data centers will take a lot of it (to put it mildly).
Hot and ColdTILE tackles the cooling problem with a specialized material that converts heat into infrared radiation. The concept may seem alien, but everything warmer than absolute zero cools this way. Our bodies, stovetops, and car engines all shed heat as invisible infrared light.
Each TILE combines solar cells, thermal insulation, processors, memory, and optical communication hardware into a single module. Beneath the electronics sits a custom heat-spreading layer that prevents dangerous hot spots. Like placing a scorching pan onto a baking sheet, it distributes heat over a much larger surface before channeling it to the radiator.
The modules are designed to work together. Thousands of TILES could link into a giant computing mosaic, each acting as a mini computer connected to its neighbors. Like a modern power grid, the distributed architecture improves reliability—if one TILE fails, others can jump in—while simplifying power distribution and thermal management.
The modular design also solves a practical challenge: Rockets don’t have much cargo space. Similar to NASA’s Roll-Out Solar Arrays, a TILE-based data center could launch in a compact configuration before unfolding into a large, flat computing platform in orbit.
Looking further ahead, the team envisions launching multiple interconnected arrays in succession, like strings of pearls. Each could function as an independent data center that exchanges data with others, effectively extending cloud computing into orbit.
Sophia Space is targeting a demonstration mission in late 2027. By 2030, the team estimates an array of 2,000 TILEs could deliver up to a megawatt of dedicated computing power. To put that in perspective, a single ground-based data center can deliver hundreds of megawatts of computing power, and future data centers will stretch that number into the thousands.
There are challenges beyond the purely technical. Earth orbit is crowded with active spacecraft and debris, raising the risk of collisions. SpaceX’s Starlink satellites, for example, perform frequent collision-avoidance maneuvers after a close call in 2019. The breakup of a Chinese Long March rocket in 2024 threatened an estimated 1,000 satellites. Large constellations of data centers—SpaceX has plans for up to a million in low Earth orbit—would add even more traffic.
Beyond collisions, astronomers are worried that expanding satellite numbers could hinder our ability to study the universe by interfering with telescope observations and radio astronomy.
For now, orbital data centers are unlikely to replace their terrestrial counterparts. Instead, they’re more likely to complement them, processing data collected by spacecraft and beaming only the results back to Earth. Although the field is ridden with hype and controversy, there’s also promise and momentum is clearly building.
“It’s just kind of exploding,” Sergio Pellegrino, a Caltech engineer who collaborates with Sophia Space, told The New York Times. “We need to become more comfortable with space doing things for us.”

‘Apple is one of the greatest companies of all time,’ says OpenAI
In an open letter, OpenAI this week turned to the court of public opinion in its existential war against Apple with a public notice in which the company refutes the iPhone maker’s claims concerning wholesale use of confidential information.
You can detect the depth of enmity between both firms in OpenAI’s opening lines to its letter, which begins: “Apple is one of the greatest companies of all time,” and then moves swiftly into defending itself against company’s claims, while attempting to characterize Apple’s complaints as weak.
What Apple claimedAs reported elsewhere, Apple filed suit against OpenAI in the US District Court for the Northern District of California on July 10. The litigation names OpenAI Foundation, OpenAI Group PBC, io Products, Chang Liu (former senior systems electrical engineer), and Tang Yew Tan (former vice president of product design for iPhone and Apple Watch, now OpenAI’s chief hardware officer), and alleges breach of intellectual property agreement and misappropriation of trade secrets under the Defend Trade Secrets Act. The company has since then filed preservation orders to protect evidence.
Apple’s complaint is more detailed than that. Among many other things, it claims Tan allegedly directed job candidates still at Apple to bring “actual parts” to interviews for “show and tell” sessions. It also alleges Tan distributed an internal Apple document describing Apple’s own departure security protocols to new hires before they resigned. Liu is separately accused of failing to return an Apple laptop and using it to download confidential technical documents.
OpenAI’s rebuttalNow, OpenAI argues Apple’s trade-secret lawsuit is based on factual errors, poor communication and misleading claims. It says Apple mistakenly contacted the wrong OpenAI lawyer after confusing two people with the same surname, falsely claimed a phone call had occurred, then acknowledged both mistakes without raising the allegations later included in the lawsuit. (Apple says it sent OpenAI a warning letter back in February with no response, which undercuts OpenAI’s “we offered to resolve this before litigation” statement.)
OpenAI argues that Chang Liu was responding to requests from Apple colleagues seeking help locating Apple files, reflecting Apple’s own access-management failures rather than misconduct. It also claims Tan consistently instructed OpenAI staff not to seek or use competitors’ confidential information. OpenAI maintains it neither possesses nor wants Apple’s trade secrets, offered to resolve concerns before litigation, and finally argues that Apple’s request for a preliminary injunction is unnecessary and unsupported.
What Apple might actually argueWill Apple see it the same way? That seems unlikely, in part due to the extent of the claimed infractions. Apple will point to the hundreds of former Apple employees now at OpenAI, including former Chief Designer Jony Ive. In doing so, it will likely argue that the remit of the case is not defined by erroneous legal correspondence, though that is probably seen as an error. Instead, the substantial claims it’s likely to focus on are that OpenAI has been engaged in a multi-front attempt to accumulate information pertaining to Apple and its design processes through recruitment and the way it recruits.
It’s feasible both arguments have some validity. OpenAI might be right in pointing out weaknesses in Apple’s own approach to internal communications in terms of secrecy. And Apple is correct in pointing out that OpenAI moved to abuse those vulnerabilities, weaknesses in its approach that have only been identified during OpenAI’s campaign to grab secrets.
While the Apple lawyer’s error in approaching OpenAI might be an unforced error that helps the AI firm cast doubt on Apple’s claims, it doesn’t necessarily invalidate them — and both sides believe themselves to be justified. Deciding which company is in the right will be a matter of law and not of public opinion.
Which side does the smoking gun face?To prove its position, OpenAI shared some correspondence. These communications do seem to show a failure at Apple to properly implement device management over employee accounts, including the claim that personal iMessage accounts are routinely used to share corporate correspondence. That may be true, and shouldn’t be – it’s an obvious weakness in corporate security.
At the same time, the correspondence also shows hints of job opportunities at OpenAI for and to a former colleague, which kind of proves part of Apple’s point in terms of steady employee poaching. “I can always give you some fun side projects,” one message said.
Of course, interaction between former colleagues is inevitable,. But at the level of seniority here, it feels plausible this could be in breach of any off-ramping arrangements reached between Apple and its former employees. No doubt, courts will decide that – though it does underline Apple’s claims that OpenAI instructed former Apple staffers about how to leave without reaching such agreements.
“This isn’t Apple getting it wrong. It is OpenAI getting caught with its hand in the hardware cookie jar and then writing a blog post about how the jar was left unlocked,” US tech thought leader Brian Roemmele wrote on X.
Where happens next?Ultimately, what comes next is up to Apple and OpenAI. The two companies might reach a deal out of court, or be forced into an agreement by the legal system. The existential nature of the rivalry suggests the latter, rather than former.
It is also very telling that OpenAI, which now has more than 400 former Apple employees on its teams, including many former designers, also claims: “Apple’s request for a preliminary injunction is both based on false information and completely unnecessary because we do not have, nor want, any of their trade secrets. We’re much more interested in building innovative products and technologies that push the frontier.”
While Apple hasn’t yet responded, it will be interesting to see whether whatever hardware OpenAI ships looks and behaves like any released or unreleased Apple products; the latter will now be able to bring details of its own historical project design decisions — and the people who made them — to court.
I think this case will play out over time. Perhaps the most interesting question is whether OpenAI has taken what it knows about Apple to create its own internal product design and development LLM models. Would that use be legitimate? It would, after all, not be the first time an AI company has trained its models on other people’s creative energy.

AI agents get better at IT ops, but only with humans in the loop
AI agents are performing roughly 1 in 3 actions in enterprise IT workflows (but that share is rising quickly), while human analysts are rejecting about one-quarter of AI-proposed actions (but that rate is falling), according to a new study of tens of thousands of human-AI interactions. Operational data, rather than underlying AI infrastructures, is often the culprit when things go wrong.
Human analysts are approving the most consequential actions, managing exceptions, and supervising and shaping agentic systems, while AI agents are carrying out routine tasks and executions, automation platform provider Fixify found in the study.
“That may sound less dramatic than replacing the help desk,” Matt Peters, Fixify’s co-founder and CEO, wrote in a blog post. “It’s also a much more credible path to changing how IT work gets done.”
Building scaffoldingFixify identified four steps of agentic work: Planning, proposing, approving or declining, then acting on approved steps.
It analyzed nearly 18,000 plans and over 147,000 actions executed by agents across 40 companies over a three-month period, finding that agents are taking over one-third of IT actions, most notably in software, applications, security, and collaboration work where requests tend to be “repeatable and easy to reverse.”
Tasks that are well understood and that present low risk are best suited for the current generation of agents, Peters wrote. Human analysts remain closely involved in higher-stakes areas like identity verification, setting up and removing IT access (onboarding and offboarding), and hardware environments.
However, AI’s share of the work is increasing as feedback loops improve: Over the three-month period, human approval of AI-proposed actions rose from 23% to 41%, and rejection fell from 27% to 16%, Fixify found.
The company identified six types of actions in AI automation. Running a skill — actually doing something — accounted for 39.4% of all actions). Most of the rest were coordination: sending a message to the human requester (27.7% of actions), leaving an initial comment (13.2%), giving instructions to a human analyst (9.8%), or waiting (8.8%). Running entire workflows accounted for just 1.1% of actions.
AI is building “scaffolding” that wraps around meaningful changes, often planning far more scenarios than the agent will execute. Typically, agents map out 15 possible actions but run only two, Fixify said.
“The agent maps the paths a request could take, then walks down the path that makes the most sense as it meets reality,” the study said.
Peters pointed to one example where an AI agent identified which team needed access to process a high-volume type of ticket. Rather than fully automating the process, the agent did the initial triage, asked questions, then routed tickets to the team that had the information to act immediately.
“We didn’t need a world-ending hive mind,” he said. “We just needed to point a little conversational intelligence in the right direction.”
When AI breaks downIT automation typically involves analyzing tickets and moving them along; in other words, low-risk tasks.
But agents do participate in areas like security (albeit only about 6%), most notably adding and removing people from groups or channels, unlocking accounts, resetting passwords, analyzing multi-factor authentication (MFA), provisioning (or deprovisioning) accounts, and assigning software licenses.
However, this identity-lifecycle work is where agents failed the most, particularly in onboarding and offboarding and identity-access management (IAM), the study found. “Hardware and connectivity changes rarely fail; identity-lifecycle changes fail three-to-nine times as often.”
Why AI breaks downThanks to human-in-the-loop controls, Fixify was able to analyze scenarios where agent recommendation diverged from human judgment. This occurred about 23% of the time.
The largest failure category (nearly 50%) was ‘target not found,’ meaning the agent couldn’t uncover what it needed. This typically comes down to poor data: A user, group, account, or resource was not where the system expected it to be. When people change teams, groups are restructured, accounts are renamed, or work has already been done but not reflected in the system, this is more of an identity hygiene problem than an AI problem. The system needs cleaner and more current data.
Invalid inputs accounted for around 29% of failures, followed by unhandled errors, denied permissions, or invalid operations or configurations. The latter signal “real breakage” in integrations, according to Fixify.
AI becomes more sophisticated over timeThe good news is that AI automation improves over time, even if it might take a while. In hybrid systems, humans keep the most consequential changes under their own control, and iterative rejection and approval helps AI learn.
Over time, agents’ plans get leaner and they start to re-plan when conditions change, rather than pre-planning all kinds of scenarios that may never occur. “That’s a sign of sophistication,” the study said. “Adapting in the moment is a more advanced behavior than trying to pre-script every contingency.”
In turn, humans second guess the system less often and feel comfortable handing off more work. Instead, they control how agents behave, make high-impact decisions, and handle exceptions. “The hardest requests remain human-heavy, especially those that require repeated replanning or contextual judgment,” the study said.
How teams can adapt to AI agentsAs agentic AI becomes embedded in more workflows — and at deeper levels — enterprises must evolve to accommodate, Fixify emphasized.
This means investing in clean identity data and building strong playbooks, review workflows, and reliable integrations.
Teams should judge agentic tools by their supervision loop and view rejections as a training process, Fixify advised. Analyst time, queues, and metrics should be built around reviewing proposals. Agent replanning can be seen as a routing signal: A single replan might indicate healthy adaptation, while repeated replanning means ambiguity, irrelevance, or unclear policies.
“Make the review surface easy to understand so analysts can assess proposed actions and make quick decisions about how to proceed,” the study advised. “This is where the analyst’s attention belongs.”
