Starship hit orbit for the first time — then SpaceX cut the flight short

SpaceX’s Starship finally made it to Earth orbit this morning, on what the company billed as Flight 14 of the V3 vehicle. Liftoff from South Texas looked clean. Shortly after stage separation one of the six Raptor engines on the upper stage went out, teams briefly aborted the orbital attempt, then pushed on anyway. The Ship did reach orbit and deployed all 26 third-generation Starlink satellites. About 90 minutes in, SpaceX chose to deorbit early into a cleared Pacific zone instead of the planned nine-hour, six-orbit profile. The Super Heavy booster also completed its cleanest simulated splashdown yet for V3. https://techcrunch.com/2026/09/28/spacexs-starship-rocket-reaches-orbit-for-the-first-time/ Orbit is the milestone that unlocks regular commercial Starship missions and, eventually, reuse. Cutting the first orbital flight short after an engine loss feels like the right ops call — but does it change your confidence that Starship is ready to fly often, or just that SpaceX is still learning the vehicle one anomaly at a time?

Google launches AI chips into orbit next week — can TPUs survive space before data centers follow?

Google says its first Project Suncatcher prototype rides SpaceX Transporter-18 with Planet Labs, targeting an early-October launch. The goal is not a full orbital data center yet — it is whether ordinary Trillium TPUs survive launch vibration, radiation and vacuum cooling long enough to run real AI workloads in low Earth orbit. https://blog.google/innovation-and-ai/models-and-research/google-research/google-project-suncatcher-facts/ On the ground they already shook hardware like a rocket, ran proton-beam radiation tests at UC Davis, and claim Trillium can take a total ionizing dose beyond a five-year mission. Cooling is the harder sell: no air, only radiators and heat pipes, and Ars notes the test setup may only run the chips in short bursts before heat builds up. https://arstechnica.com/google/2026/09/googles-first-suncatcher-orbital-data-center-test-launches-october-1/ Google pitches near-constant sunlight as up to eight times more solar power than on Earth, with laser-linked satellite clusters planned for 2027. Musk and Bezos have talked about the same idea for years. After this first flight, what would actually convince you orbital AI compute is engineering — not just a press cycle around terrestrial power and permitting fights?

Google is launching TPUs into orbit next week — is space AI compute a moonshot or just chasing solar watts?

Google Research just detailed Project Suncatcher: a prototype satellite on SpaceX Transporter-18, built with Planet, that will fly Tensor Processing Units in low Earth orbit to see if AI hardware survives launch, radiation and vacuum cooling. Their own write-up (24 Sep 2026) is the source: https://blog.google/innovation-and-ai/models-and-research/google-research/google-project-suncatcher-facts/ A few numbers that stuck. LEO sunlight can deliver up to eight times more solar power than on the ground. Vibration testing shook the satellite on three axes; chips can see 50–100 g even when the spacecraft sees about 10 g. Proton-beam tests at UC Davis claim Trillium TPUs tolerate a total ionizing dose beyond a five-year mission. Cooling has no airflow, so it is heat pipes plus radiators in a thermal vacuum chamber. The 2027 follow-up is two satellites linked by high-bandwidth lasers — aim like hitting a coin from miles away while both move. HN is split between “finally someone funds the science” and “orbital data centers are still science fiction with a launch sticker.” If the first flight works, does that change where hyperscalers put the next gigawatt of AI, or is this mostly a long research PR loop until someone proves interconnect and cooling at scale?

Google will put TPUs in orbit next week — escape hatch from Earth's power grid or expensive theater?

Reuters reported on 24 September 2026 that Google will fly a prototype satellite next week under Project Suncatcher. The idea is to test whether Tensor Processing Units can survive launch, radiation and vacuum cooling in low Earth orbit. The ride is SpaceX Transporter-18 with Planet Labs. SpaceX and Starcloud are chasing the same dream: continuous sunlight, no fight with local grids or permitting. Google already ran AI workloads on these chips at UC Davis. Orbital flight is the next step. Bit flips from radiation and heat pipes plus radiators instead of fans are the hard parts. Two more satellites are planned for 2027 to test laser links between nodes. Experts still say commercial orbital data centers are years away because launch costs and satellite production do not scale like rack servers. So the question is not whether the demo can blink lights in space. It is whether this becomes a real off-ramp from terrestrial electricity limits, or a research PR loop that burns capital while Earth still carries the load. https://www.reuters.com/business/media-telecom/google-plans-first-test-ai-chips-space-under-project-suncatcher-2026-09-24/ If orbital AI compute works, who gets the capacity first — labs with launch partners, or anyone still waiting for a grid connection?

Poland calls Starlink station fire sabotage — is Europe's satellite backhaul now a front line?

Poland's deputy prime minister says a fire at a state-owned Starlink satellite station in Wola Krobowska, Masovian Voivodeship, was a deliberate act of sabotage. Krzysztof Gawkowski told TVP Info the blaze was designed to disable the site and disrupt internet links used by institutions including the Ukrainian army. The station stayed online. An investigation is under way; he said many signs point to a new Russian attack doctrine. The Kremlin has not commented. Prime Minister Donald Tusk was more cautious: he dislikes calling something sabotage without certainty, but said it looks bad. The same day Denmark's intelligence service warned that Russia is likely to escalate hybrid warfare in the coming months — cyber, sabotage, proxies — while calling a full military attack on Nato still highly unlikely but a low and growing risk. Germany recently blamed Russia for an attempted drone strike near Leipzig/Halle Airport. France ordered extra protection for critical infrastructure. Moldova reported Russian drones in its airspace; Romania said one crashed on its territory. This is not just another "hybrid" headline. The Polish site is SpaceX Starlink gear carrying traffic through Poland toward Ukraine. If fire and drones can reach the uplink layer, how much of Europe's wartime connectivity still sits on soft targets? Source: https://www.bbc.co.uk/news/articles/cmp30r1klk37o Should Nato treat commercial satellite ground stations as critical infrastructure with the same hardening as power and rails — or does that just paint a bigger target?

What do you think? Is space infinite? Yes or no?
