To Keep GPS Constellations From Drifting, Look To The Moon
Posted on: 6 Oct 2026

Global Positioning Systems are a key feature in everyday life for much of the world’s population. Whether it’s ensuring a ship delivers its goods safely, or you’re able to avoid a road closure on your commute home, GPS can help. But the system has a weakness - it relies on ground stations that could suffer from blackouts, natural disasters, or cyber attacks. And if those ground stations go offline for long enough, the whole system itself can begin to “drift”. Aerospace engineers have been attempting to counteract this problem for years, but so far with little success. But a new paper from a research team led by Xia Lin and Baojun Lin at the Shanghai Engineering Center for Microsatellites, and published in Satellite Navigation, explains a potential answer to this problem - link the GPS satellites up with some in orbit around the Moon.

A Buried Volcano on the Moon Hints At An Ancient Lunar Dynamo
Posted on: 6 Oct 2026

Scientists know for certain the moon doesn’t currently have a magnetosphere. But they’ve been debating for decades about whether it ever did. Data from both Apollo samples and orbital scientific instruments have proven divisive, and so the debate still rages. But a new paper from researchers at ETH Zurich, DLR, and the Institute of Applied Geosciences hopes to resolve the debate once and for all - by definitively proving that the Moon did, indeed, once have a magnetic dynamo.
