The prototype satellite for Google's Project Suncatcher, an initiative testing AI data centers in orbit, is online and sent Earth a haiku generated by the Gemma 4 model, according to TechCrunch and The Verge reports published on Friday, October 30.

Cortexplor first covered this same spacecraft, nicknamed MVP, on September 25, when Google announced plans to launch it on October 1. The new reports confirm the satellite has reached orbit and has now received and answered its first command from the ground — the new development in this story. The spacecraft launched aboard a SpaceX Falcon 9 rocket alongside more than 100 other payloads, per TechCrunch. It carries four Google Tensor Processing Units (TPUs), but because it generates up to 1 kW of electricity, it can only keep one TPU running at a time, for about 20 minutes, according to the same report.

What the team tested

After roughly three weeks of testing the spacecraft's subsystems, Google engineers sent the first prompt to Gemma 4, the Google DeepMind model preloaded on the satellite, asking it to write a haiku about being in space. The result, published by Google and cited by both outlets, read: "Blue marble below / Data streams in silent grace / Starlight feeds my core." The team also tried space-themed limericks and asked the satellite to report on the orbital conditions around it, per TechCrunch.

What comes next

Per both reports, the next phase will test how the chips perform under thermal stress and radiation exposure in orbit. Radiation can cause so-called "bit flips" — a change to a value stored in chip memory — that can corrupt data without triggering normal monitoring tools, according to TechCrunch. Ground testing had suggested radiation's impact would be minor for inference workloads but bigger for training, and the mission will test that in real conditions rather than simulation, per the same report.

If results hold up, Google plans to launch two more satellites with the same chips in 2027, with higher power generation and optical links between spacecraft, according to Google as cited by both TechCrunch and The Verge.

Why Google is testing this

Suncatcher is a long-horizon Google project, designed to become economical only in the 2030s, per TechCrunch. The report notes that Alphabet, Google's parent, is also an investor in SpaceX, which is pursuing a similar vision for orbital data centers — though Suncatcher is built around high-speed links between closely flying satellites to pool processing power, while SpaceX's satellites are expected to orbit too far apart for that, according to TechCrunch. Both plans depend on SpaceX's Starship, the still-in-development reusable rocket, becoming fully and rapidly reusable.

TechCrunch cites a peer-reviewed analysis by Suncatcher's own researchers estimating SpaceX would need to fly Starship 1,800 times to match, with orbital data, the same learning-driven cost reductions it achieved by reusing earlier vehicles — an estimate from that study, not confirmed elsewhere. The report also places Suncatcher among other space-computing bets: companies like Starcloud and Cowboy Space expect to run inference on individual satellites rather than building the inter-satellite network Google's project is aiming for.

A costly bet amid pressure on AI spending

TechCrunch frames the test against a tougher week for Google's AI spending story: the report notes Alphabet's stock fell after the company said its push to add AI to search was hurting ad revenue growth. The outlet describes Suncatcher as a long-term infrastructure bet whose payoff depends on how the rest of the company navigates the near-term pressures and opportunities created by AI.

In practice

  • The satellite is still in testing; there is no orbital cloud service available for outside use.
  • It carries 4 Google TPUs but can run only one at a time due to power limits, per TechCrunch.
  • Next milestone: two more satellites launching in 2027, with more power and optical links between them, according to Google.
  • The current mission is testing chip resistance to space radiation, which can corrupt data without tripping normal monitoring alarms.
