We don’t often think about gravity, the invisible force that anchors us to Earth, as it always seems constant and dependable. However, it will slightly vary, sometimes by enough to make you weigh ...

Thanks to Newton, we all know that what comes up must come down. But did you know that what comes down comes down with just slightly less pressure if you’re standing in Europe or the South Pacific? We ...

The first gravity maps of the GRACE-FO mission are now available. The twin satellites of the GFZ German Research Centre for Geosciences and NASA continuously measure the Earth's gravitational field ...

Six months into its mission to precisely measure Earth's shifting water masses and map their effects on Earth's gravity field, the joint NASA-German Aerospace Center Gravity Recovery and Climate ...

Video: Find out how the GOCE mission will map Earth’s gravity in unprecedented detail (Courtesy of ESA) A sleek satellite that is set to make the most detailed map of the Earth’s gravity took to the ...

Researchers in Austria are investigating the effects of the Earth's atmosphere on our planet's shape, its rotation and its gravitational field. The researchers' aim is to develop a better ...

Nasa is planning to launch two satellites that will be used to plot variations in the Earth's gravitational field (pictured in an exaggerated form). The Gravitational Recovery And Climate Experiment ...

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.

This temporal lag is a direct consequence of Albert Einstein’s Theory of General Relativity. The rule is simple: the weaker ...

Measuring the time discrepancy between Earth and Mars will help make future navigation and communication systems on the Red ...

On Earth, knowing the time feels simple. Your phone pings the same second as a GPS satellite and an atomic clock in a lab.

There's going to be a changing of the guard in space. On Tuesday, NASA is launching two new satellites, collectively called GRACE, to replace two that have been retired after 16 years in orbit. GRACE ...
