Desktop seismology: How a maker-inspired device is changing seismic monitoring

The Raspberry Shake — a personal seismograph invented in 2016 and named after the computer that powers the instrument (the Raspberry Pi) — was intended for hobbyists. But the device’s usefulness quickly became apparent to a much wider audience, including scientists and educators around the world.

Cassini's legacy after two decades

Scientists on Earth have received the last submission from the Cassini spacecraft. It descended into Saturn’s atmosphere at 122,500 kilometers per hour, which caused it to melt, thereby ensuring that Saturn’s moons Titan and Enceladus would remain protected from possible contamination by any errant Earth microbes. Cassini scientists had considered other options for the spacecraft’s end, including leaving it to float endlessly in space or parking it in orbit around Saturn. But ultimately, they chose to have it descend into Saturn’s atmosphere after deciding the data that could be returned from the descent were more valuable than any further data it might obtain by remaining in space. Scientists will make discoveries from these data for decades to come.
