On July 12, 1985, the launch of the Space Shuttle STS-51-F was halted at T−3 seconds due to a coolant valve malfunction in engine number two, leading to an automatic abort. The shuttle successfully launched on its second attempt on July 29, 1985, after a delay caused by uplink issues, but experienced an in-flight engine sensor failure that resulted in a lower-than-planned orbit. This was the only RS-25 engine failure during the shuttle program's operational history.

Tom's Hardware testing found average-to-below-average benchmark performance, partly because its primary DDR5-6000 RAM kit wasn't officially supported and required a secondary kit for testing.

The Economist reports that despite fears of AI-driven job destruction, US employment data shows no broad downturn: unemployment sits at 4.1% and young workers' job prospects remain strong. While companies like Microsoft, Meta, Block and Intuit have cut roles tied to automation—averaging about 16,000 AI-related layoffs monthly—the publication estimates AI has simultaneously generated roughly 1 million new jobs through data-center construction, startup hiring and new corporate AI roles, dwarfing the roughly 200,000 layoffs attributed to the technology since mid-2023.
