Project Suncatcher is a long-term research effort to explore running AI computing in space. After launching its prototype satellite on October 1, the team completed initial commissioning, powered up the onboard host and TPU trays, and ran early machine-learning tests. The key milestone came when a ground station sent a prompt to the satellite’s Gemma 4 open model and received its first AI-generated response from an orbiting, data-center-class TPU. During a pass over Svalbard, Norway, the model produced a haiku about space, confirming that the system could accept a prompt, compute an answer in orbit, and send it back to Earth.
The team then tested other prompts, including requests for space-themed limericks and reports on the payload’s technical status. These demonstrations establish that the hardware can perform basic AI workloads in orbit, but the next challenge is to determine whether it can do so reliably in harsh conditions. Planned tests will examine TPU performance under thermal stress and radiation exposure. If the chips prove dependable, the project can advance toward its next milestone: two interconnected satellites, targeted for 2027. The successful response is an initial technical step toward the broader goal of exploring AI compute infrastructure in space, not a completed operational system.

Italian computing grew rapidly from 1954 to 1964, led by Olivetti and its early electronic computers. The period also marked the decline of Italy’s ambitions to build a domestic computer industry. (zeitgame.net)
Hermantown’s City Council unanimously approved key agreements and permits for Google’s proposed 1.7-million-square-foot data center after hours of public comment. The decision came despite strong local opposition and protests that had twice delayed the vote. (mprnews.org)
Amazon disabled Alexa voice commands for switching to AUX input on several older Echo speakers, including select Echo, Echo Plus, and Echo Studio models. Owners can still use the AUX ports, but must switch audio sources without voice commands. (engadget.com)
A father and his 12-year-old son spent two months building a tiny computer-game device inside an Altoids tin, reusing parts from a robot and fitting in an Arduino Nano, display, and battery. After setbacks with wiring, soldering, and tight packaging, they completed a working project and shared a video of the result. (uvdn7.github.io)
A homebrew computer pairs a 10 MHz Motorola 68000 with 1 MB of SRAM and two 32-bit PCI slots. A Xilinx Spartan II FPGA bridges the processor to PCI, while a CPLD handles glue logic; the system is working and ready to use. (maniek86.xyz)
