Heat limits Google's four orbiting TPUs to 15-minute runs
Google's Project Suncatcher put a satellite carrying four TPU chips into orbit on Oct. 1 to test AI computing in space. NPR reported the chips run only 15 minutes before cooling down, and that limit decides how much computing each launched kilogram can deliver.

buildOne report1 publisher Cowboy Space's Reason-1 proves its radio link from orbit as the laser power test waits
Baiju Bhatt says Cowboy Space's first satellite, Reason-1, is in orbit and in daily contact with its ground team. That establishes the company can operate a spacecraft, while the laser link meant to beam solar power to Earth has no reported result yet.

Google is flying four TPUs, roughly one server's worth of compute on a kilowatt of solar power, in Project Suncatcher's first orbital test. The satellite can show whether the chips survive heat and radiation in orbit, a smaller question than whether computing there is cheaper.

Cowboy Space joins the FCC queue for grid-free orbital compute forecast to scale in the 2030s
Cowboy Space has asked the FCC to approve Stampede, a 20,000-satellite data center constellation it says can skip the power grid entirely. Forecasts around these filings put meaningful capacity after 2030, too late for any power plan due this decade.

Google launches its first Project Suncatcher satellite on October 1 with four TPUs on about 1kW of solar, roughly one data center server's worth of compute. It can show whether the chips stay cool in orbit, but the laser links any capacity case needs wait for a two-satellite test in 2027.

buildConfirmed5 publishers Google's MVP satellite takes four TPUs and about 1 kW of solar power into orbit to test whether AI chips survive radiation and shed their own heat. Its results will show whether rebooting away bit flips and cooling through a radiator can carry into the constellations Google has already sketched.

Google flies one server's worth of TPUs on 1 kilowatt of solar power on Oct. 1, its first hardware test for orbital AI data centers. The flight tests chip survival and cooling while SpaceX's and Blue Origin's far larger constellations still wait on FCC review.

ESA holds β¬450mn of its β¬760mn Nyx contract as options it can still decline
About β¬20bn and 51 deals were announced at the Paris space summit, on top of an ESA budget member states had already approved. The dates suppliers will be judged against came from Macron's address, not from a contract.

Fermi Explorer budgets $15 million to send one kilogram toward Alpha Centauri
The nonprofit's founders also run Starcloud, and no one now alive can check the arrival, so the auditable claim is whether a 100-to-200-kilogram spacecraft and a launch contract exist by 2029, and what that kilogram of payload turns out to be.
