Suncatcher TPU Satellite: How to Track It and What Happens Next

Google Project Suncatcher key facts: four Trillium TPUs launched into orbit on Transporter-18

Google's Project Suncatcher satellite is in orbit, and you can track it yourself: the U.S. Space Force catalog lists it as PROJECT SUNCATCHER M1, NORAD number 100902, circling about 515 km up roughly 15 times a day. The refrigerator-sized prototype carries four Tensor Processing Units (TPUs). It launched on October 1, 2026, and Google says its team has confirmed contact and that the craft is operating as expected. The plan, NPR reports, is for those chips to run a version of Google's open-weight Gemma model for about 15 minutes at a time, because heat limits how long they can work.

Updated October 20, 2026.

What happens next is mostly a wait for data. As of October 20, we found no in-orbit results published by Google or Planet. Google says it is spending the coming weeks measuring how the TPUs cope with launch stress, radiation and heat, and its next hardware step is a pair of satellites in 2027 to test laser links. The flight is the first in-orbit test of Project Suncatcher, Google's research effort to see whether space could one day host large-scale AI computing. It is still a small experiment, and Google says so, but the question has moved from the pad to space: can everyday data-center hardware work beyond the atmosphere?

How to track the Suncatcher satellite

Use its catalog number. Search for NORAD ID 100902 (international designator 2026-227V). The U.S. Space Force catalog, as published by CelesTrak, names it PROJECT SUNCATCHER M1, the same name SpaceX used on its Transporter-18 deployment list, and lists the United States as owner.
Open a live tracker. N2YO's page for NORAD 100902 shows where the satellite is right now and offers 10-day pass predictions once you set your location.
Read the orbit numbers. CelesTrak lists a perigee of 513 km, an apogee of 516 km, an inclination of 97.44 degrees and a period of 94.91 minutes. That works out to roughly 15 orbits a day on a near pole-to-pole path.
Pull the data into your own app. Request CelesTrak's orbital elements in JSON format. When we checked on October 20, the classic two-line element (TLE) format returned no data for this six-digit catalog number, so use the JSON output instead.
Watch for results, not just position. A tracker tells you where the satellite is, not how the chips are doing. Google says it is "excited to share more as the mission unfolds" in its October 1 mission post; until it does, there are no public figures on chip errors, temperatures or uptime.

What happened

On October 1, 2026, Google's prototype satellite for Project Suncatcher, built with Planet Labs, launched aboard SpaceX's Transporter-18 rideshare mission from Vandenberg Space Force Base in California, according to a Google blog post by Travis Beals, senior director of Paradigms of Intelligence. "Our team has confirmed contact with the satellite and it is operating as expected," Beals wrote the same day.

Planet Labs separately said the mission carried the first Project Suncatcher demo along with Tanager-2 and 18 SuperDove satellites, and that it had made initial contact with the Suncatcher prototype and begun commissioning, per a Business Wire release carried by Yahoo Finance. Planet called it its 40th successful launch. SpaceX's Transporter-18 deployment list names the craft as Project Suncatcher M1.

Google is not flying a specially space-rated chip. The company is testing the same kind of TPUs it uses in its data centers. GCN reports that the payload is four Trillium-generation TPUs—the first time Google's TPUs have operated in space—and that the satellite will run short AI workloads to gather performance data in orbit. NPR reports the chips will run a version of Google's open-weight Gemma model, answering simple queries for about 15 minutes at a time because of heat limits. GCN adds that Transporter-18 carried about 130 payloads and that SpaceX's schedule had Project Suncatcher M1 deploying roughly 61 minutes after liftoff.

Key details

The satellite

Name and size: Google's satellite is called MVP (and listed by SpaceX as Project Suncatcher M1). Ars Technica and SiliconANGLE describe it as about the size of a refrigerator.
Payload: four Trillium-generation TPUs, according to GCN. The IEEE ComSoc Technology Blog, summarizing a New York Times report, earlier said that is roughly the compute of a single data-center server.
Power: solar panels supplying about one kilowatt, which outlets compare to a microwave or hair dryer.
Builder: the spacecraft platform comes from Planet Labs, which normally makes Earth-imaging satellites. Ars Technica reported before launch that Google originally planned two custom satellites for 2027, then moved faster by putting its chips on a platform Planet had already built.
Launch: SpaceX Falcon 9, Transporter-18, from Vandenberg on October 1, 2026. Google and Planet both confirm the satellite reached orbit and that contact was established.

What Google is learning in orbit

Beals's October 1 post says that over the coming weeks Google will gather in-orbit data on how its TPUs handle the physical stress of spaceflight and the radiation and thermal extremes of space. The company's earlier Project Suncatcher facts post named the same three problems that ground tests can only partly answer:

Surviving launch. A rocket ride takes about ten minutes. Google says the spacecraft feels up to 10 times the force of gravity, and individual components can feel 50 to 100 times. Pre-launch vibration testing, Google reported, held up better than expected.
Radiation. Cosmic rays and solar events can flip bits or damage electronics. Google ran Trillium TPUs under a proton beam at UC Davis while they processed AI workloads and said they handled a dose greater than what they would receive during a five-year mission.
Cooling. With no air in a vacuum, heat can only leave through radiators. Google is testing heat pipes and radiators. Because of this limit, the chips are expected to run short AI workloads for roughly 15 minutes at a time and then shut down to cool, according to Google, Ars Technica, and GCN. NPR says the planned test workload is a version of the open-weight Gemma model.

Google also says its peer-reviewed paper on the research behind the mission is now available in the journal Joule.

What comes after

Google still plans to launch two satellites in 2027 to test the laser links that would connect future clusters. Beals wrote earlier that the goal is high-bandwidth laser links across very short distances, which existing space systems are not built for. Designs under study include clusters of about 81 satellites within roughly a one-kilometer radius, according to Google's research framing and coverage by Futurum Group and Data Center Dynamics. On mission length, Beals told NPR the goal is for the satellite to stay operational for a year; Ars Technica had earlier said only a few months. NPR also corrected its story to say this prototype is in a standard orbit and uses batteries; the sun-synchronous, battery-free design is the plan for future satellites.

Why it matters

The energy debate. AI data centers use large amounts of electricity, and local opposition to new sites is growing. Google says satellites in low Earth orbit can get up to eight times more solar power than a panel on Earth, and that is the appeal.
A crowded field. Reuters noted before launch that SpaceX and Starcloud are also pursuing orbital data centers. According to The Register, SpaceX's AI arm, SpaceXAI, aims to put its first space-based test systems in orbit by the end of next year.
Google is playing down the hype. James Manyika, Google's senior vice president for research, told the New York Times, as quoted by the IEEE blog: "We don't expect, to be perfectly frank, that we'll have anything usefully operational in the next few years." Google has said it expects orbital data-center costs to approach those on the ground in the mid-2030s, if launch costs keep falling.
The skeptics have points. Reuters said experts consider the idea years from being commercially viable because of launch costs, engineering constraints and satellite production limits. The Register cites a Gartner analyst, Bill Ray, who called the concept "peak insanity" earlier this year. It also reports that Google's numbers suggest roughly 1.3 square meters of radiator area to shed the heat of a single TPU, so a satellite with dozens of chips would need a very large radiator.

Project Suncatcher vs Starcloud: orbital AI compute compared

Google is not the first to put a data-center AI chip in orbit. Startup Starcloud got there first with a single Nvidia GPU, and TechCrunch reports it has raised a $250 million extension that values the company at $2.3 billion, with Nvidia among the backers. Here is how the two efforts compare on the facts reported so far:

	Google Project Suncatcher prototype	Starcloud-1	Starcloud-2 (planned)
Launched	October 1, 2026 (SpaceX Transporter-18)	November 2025, per Fortune	2027, two satellites on rideshare flights, per TechCrunch
AI chips	4 Google Trillium TPUs (GCN)	1 Nvidia H100 data-center GPU (Fortune, TechCrunch)	Not detailed in TechCrunch's report
Power	Solar panels rated at about 1 kW (GCN)	Not stated in our sources	About 8 kW per satellite (TechCrunch)
AI work	Planned: a version of Gemma in roughly 15-minute bursts (NPR)	Ran Google's Gemma (Fortune); first to train a model on an H100 in orbit (TechCrunch)	Orbital inference for customers including U.S. government agencies (TechCrunch)
Status	Planet began commissioning Oct 1; Google says it is operating as expected; no results published as of Oct 20, 2026	Operating in orbit as of August 2026 (TechCrunch)	Not yet launched

Sources for the table: GCN, NPR, Fortune and TechCrunch.

What's next

The launch milestone is done. Google says the coming weeks are about collecting in-orbit data on launch stress, radiation and thermal extremes, then refining designs with those results. Planet has begun commissioning on the Suncatcher prototype. Google has said it wants to share what it learns, but it has not published a detailed timeline for first public results. Look for early information on bit-flip rates, chip temperatures and how often the cooling system forces a shutdown.

The bigger open questions remain economic. Getting from four chips to something that competes with a land-based data center will depend on launch prices, radiator size, laser-link performance and how quickly satellites can be built. The Register reports that space data-center startup Orbital says its business depends on launch costs falling from around $7,000 per kilogram today to $10, a target it says many people doubt will be met. Google's 2027 two-satellite laser-link mission is the next major test of that path.

Quick answers

What else launched with Suncatcher in October 2026?

Suncatcher rode SpaceX's Transporter-18 rideshare on October 1, 2026, as one of about 130 payloads. Planet's 20 satellites on it were the Suncatcher prototype, Tanager-2 and 18 SuperDoves. Fortune and InvestorPlace report the same rocket carried Cowboy Space's Reason-1, which will test sending solar power to Earth, and Star Catcher's Protostar, built to beam power between spacecraft.

Is Suncatcher the first AI chip in space?

No. GCN says it is the first time Google's own TPUs have operated in space, but Fortune reports that startup Starcloud launched a satellite carrying an Nvidia H100 in November 2025 and used it to run Google's Gemma model. TechCrunch says Starcloud was also the first to train a model on that kind of chip in orbit.

How much computing power does the Suncatcher satellite have?

Not much by data-center standards. GCN says the four Trillium TPUs offer the computing power of a standard Google Cloud TPU v6e-4 slice, and the solar panels are rated at about 1 kilowatt. The IEEE ComSoc blog, summarizing the New York Times, put it at roughly one data-center server. Starcloud's next satellites are planned at about 8 kW each.

How long will the Suncatcher satellite stay in orbit?

Longer than it is meant to work. GCN reports the satellite is designed to operate for one year and will deorbit within approximately six years. Travis Beals told NPR the goal is a year of operation; before launch, Ars Technica had said only a few months.

What is the Suncatcher satellite's NORAD ID?

It is 100902. The U.S. Space Force catalog, as republished by CelesTrak, lists the satellite as PROJECT SUNCATCHER M1 with international designator 2026-227V and an October 1, 2026 launch from Vandenberg. Enter 100902 in a tracker such as N2YO to see its live position and upcoming passes over your location.

How high does the Suncatcher satellite orbit?

About 513 to 516 km above Earth, according to CelesTrak's catalog data. Its orbit is tilted 97.44 degrees, close to a pole-to-pole path, and one lap takes about 95 minutes, so it circles the planet roughly 15 times a day. GCN reports the satellite is designed to work for a year and to deorbit within about six years.

The power problem behind Suncatcher is already playing out on the ground, as our report on Amazon dropping secret data center NDAs amid local backlash shows.

Frequently asked questions

What is Google's Project Suncatcher?

It is a long-term research project, announced in November 2025 according to SiliconANGLE, that explores whether satellites carrying AI chips in low Earth orbit could someday run large machine-learning workloads on solar power. Google calls it a "moonshot," and describes this flight as an early test rather than a working data center.

Has Google's AI satellite launched?

Yes. The Project Suncatcher prototype launched on October 1, 2026, on a SpaceX Falcon 9 Transporter-18 mission from Vandenberg Space Force Base. Google confirmed contact and said the satellite is operating as expected; Planet also reported initial contact and the start of commissioning.

Will the satellite run AI models in space?

Yes, but only in a limited way. Google, Ars Technica and GCN report that the four TPUs will handle short queries (NPR says using a version of Gemma) in roughly 15-minute bursts before shutting down to cool. It is intended to gather data on how the hardware behaves in orbit, not to serve customers.

When did Google launch the Suncatcher satellite?

On October 1, 2026, aboard SpaceX's Transporter-18 rideshare mission from Vandenberg Space Force Base. Google confirmed contact the same day.

How many TPUs are on the Suncatcher satellite?

Four Trillium-generation Tensor Processing Units, according to GCN and NPR. It is the first time Google's TPUs have operated in space.

Has Google released results from the satellite?

Not yet. As of October 20, 2026, Google has said only that the satellite is operating as expected and that it will share more as the mission unfolds.

How long will the Suncatcher prototype operate?

Travis Beals told NPR the goal is for the mission to run for about a year.

Is Project Suncatcher a working space data center?

No. Beals called it "a very minimal test," per NPR. Google plans two more satellites in 2027 to test laser links, and its research describes possible future clusters of about 81 satellites.

Why is Google putting TPUs in space?

The main reason is energy. Google says satellites in low Earth orbit get near-constant sunlight and can generate up to eight times more solar power than a panel on Earth, at a time when AI data centers need huge amounts of electricity and face local pushback. The first prototype is meant to show whether Google's ordinary data-center TPUs can survive launch, radiation and heat in orbit before anything bigger is built.

What is Planet's role in Project Suncatcher?

Planet (Planet Labs), a company best known for Earth-imaging satellites, developed the prototype satellite with Google and supplied the spacecraft platform. After the October 1, 2026 launch, Planet made initial contact with the Suncatcher prototype and began commissioning it; Planet called the flight its 40th successful launch.

How would a solar-powered satellite data center work?

Google's long-term idea is clusters of satellites, each carrying dozens of TPUs and powered by solar panels, flying close together and linked by high-bandwidth lasers so they can share large AI workloads. Its research describes clusters of about 81 satellites within roughly a one-kilometer radius, and Google plans to test the laser links with two satellites in 2027. Future satellites are planned for a sun-synchronous orbit without batteries, but this first prototype uses batteries in a standard orbit, per NPR.

How does Google protect the TPUs from radiation and heat in space?

Before launch, Google tested Trillium TPUs in a proton beam at UC Davis while they ran AI workloads, and says they survived a radiation dose greater than a five-year mission would deliver. For heat, there is no air to carry it away in a vacuum, so Google is testing heat pipes and radiators, and the chips run in short bursts of about 15 minutes before shutting down to cool.

Who else is building data centers in space?

Reuters reported that SpaceX and the startup Starcloud are also pursuing orbital data centers, and The Register says SpaceX's AI arm aims to put its first space-based test systems in orbit by the end of next year. Experts quoted by Reuters say the idea is still years from commercial viability because of launch costs, engineering limits and satellite production.
