India’s first orbital data centre satellite

10 MAY 2026

Pixxel, a Bengaluru-based imaging satellite company, said that it would partner with the AI firm Sarvam to launch what is being described as India’s first ‘orbital data centre’ satellite, named Pathfinder.
This is expected to be a 200 kg-class satellite scheduled for orbit by the fourth quarter of 2026.
It will carry datacentre-class GPUs (graphics processing units) alongside Pixxel’s hyperspectral imaging camera, the company’s bread-and-butter business.

Orbital data centre

It is a constellation of satellites carrying the same kind of GPUs found in terrestrial data centres.
It can train and run AI models in orbit rather than only relaying data to ground stations.
Such a centre can do more demanding work than the low-power “edge” processors that conventional satellites use for tasks like signal compression.
Edge computing on earth refers to the practice of running computation close to where data is generated rather than in a centralised cloud, and the same logic, applied in orbit, is what space-based compute promises to extend.
Earth observation satellites also generate detailed, heavy image files that are expensive to downlink; processing the data in orbit and beaming down only the conclusions has long been seen as a way to ease that bottleneck.
In the right orbit, solar power is effectively continuous and offers free electricity, which proponents regard as the strongest argument for moving computation to space.
Data centres on earth are being constrained by limits on energy availability, land, water, and local regulation, all of which have been amplified by the demands of AI.

International Efforts

SpaceX CEO, Elon Musk, plans to build space-based data centers in orbit to power artificial intelligence (AI)
Amazon founder Jeff Bezos’ Blue Origin, Microsoft’s Azure Space, and Lonestar Data Holdings have already begun pilot deployments.
None of these efforts has yet produced a commercial-scale orbital data centre.

What are the challenges?

The GPU chips powered by electricity from solar panels become hot.
Now space may be cold, and common sense may suggest it a natural sink for the heat.
However, space is also empty and its vacuum eliminates convection.
The only solution to this is radiation, which requires that heat be pumped through ammonia-filled loops to deployable panels, where it can be radiated as infrared light into space.
Radiation damage is the second problem, and one that has shaped the design of every long-duration mission flown to date.
‘Bit flips’ — where bits and bytes of computers randomly change — and long-term semiconductor degradation are caused by cosmic rays, and radiation-hardened chips, which govern most space hardware, typically lag commercial GPUs by years.
Power requires storage for eclipse periods, and maintenance is effectively impossible without robotic servicing, so redundancy must be designed in from the start.
