On the night of January 20, 2018, an amateur radio operator and electrical engineer named Scott Tilley sat in his backyard observatory in Roberts Creek, British Columbia, sweeping a software-defined radio across the S-band looking for a classified American spy satellite called Zuma. He never found Zuma. Instead, his receiver locked onto a steady carrier wave at 2275.905 MHz — a signal NASA had not heard in more than twelve years, broadcast by a spacecraft the agency had officially given up on in 2005. The transmitter was IMAGE, a magnetospheric observatory the size of a kitchen island, and it was…

NASA’s own mission record says Expedition 24/25 kept him in…

Grace Hopper kept a bundle of wires, each one cut to exactly 11.8 inches. She handed them out at lectures, in Navy briefings, and to anyone who asked why the new satellite links felt sluggish. The wire, she explained, was a nanosecond. That was how far light could travel in one billionth of a second, and no amount of engineering or budget would ever shrink it. She called them her “nanoseconds.” By the end of her career she had given them out at hundreds of talks across the country. The bit became one of the most famous demonstrations in computing…

High-yield savings account rates have held steady, with some banks even increasing their rates, to start June.As of June 8, 2026, some online banks are still offering interest rates up to 5.00% APY, but these top APYs are usually limited by deposit size.
