Astronomy Daily S05E159 — Wednesday, 5 August 2026. In this episode: a power-saving “Big Bang” keeps Voyager 2 doing science, direct-to-phone satellites reach orbit, Curiosity finds a vast honeycomb field on its 14th Martian anniversary, and NASA’s Aspera prepares to hunt the universe’s missing gas. ① Voyager 2’s “Big Bang” power save • JPL engineers freed up power by simultaneously switching off certain devices and substituting lower-power alternatives, while keeping the spacecraft warm enough to operate. • The Voyagers run on radioisotope thermoelectric generators (RTGs) and lose ~4 watts per year as their plutonium decays; after nearly 50 years, power margins are razor-thin. • The move keeps three instruments — magnetometer, plasma wave subsystem and cosmic ray subsystem — running at least a year longer; the same swap is planned for Voyager 1. • Voyager 2 crossed the heliopause in Nov 2018 and is now >13 billion miles (21 billion km) from Earth; its southerly path means it is commanded via the Canberra Deep Space Network dish.
