Google has announced Project Suncatcher, a research initiative exploring the placement of machine learning compute infrastructure, including TPUs, on satellites in orbit to harness near-continuous solar power. The company says early tests will launch prototype satellites in partnership with SpaceX by early 2027. Commenters are debating the engineering and economic feasibility of space-based data centers, thermal challenges, launch costs, and whether the concept could realistically scale.

SpaceX has appointed a veteran of its Starship program to lead operations at its data centers in Memphis. The move suggests the company is placing trusted engineering talent from its rocket business in charge of its growing computing infrastructure, drawing attention from the tech and space communities.

A new technical article examines the key engineering obstacles facing underwater robot power systems, including battery endurance, pressure resistance, and energy efficiency at depth. It outlines emerging solutions such as improved battery chemistries, power management techniques, and energy harvesting approaches. The piece is aimed at engineers and researchers working to extend the operational range and reliability of subsea robotics.

Hitachi Energy has signed a memorandum of understanding with engineering firms Linxon and FTC Solar. The agreement, reported by Electrical Distributor magazine, is expected to support cooperation in the energy sector, though details of its scope and goals have not yet been made public.

NVIDIA has published a technical blog post outlining lessons learned while building TensorRT Model Connect, describing the tool as AI-native by design. The post walks through engineering decisions and design principles from the development process, offering guidance for developers building AI infrastructure on NVIDIA's platform.

A new engineering write-up describes a method for routing large language model requests across multiple inference providers using congestion-control ideas borrowed from TCP. The approach adaptively shifts traffic toward providers with lower latency or higher throughput, easing bottlenecks when one provider slows down. Commenters are discussing the trade-offs of applying classic networking techniques to AI serving infrastructure.

Cloudflare has published an account of how it built its own certificate authority to issue encryption certificates at internet scale. The company explains the engineering and trust requirements behind running a CA that serves websites worldwide, and the piece is drawing wide attention among developers and security engineers discussing web encryption infrastructure.
