A portable optical lattice clock on a trailer has been used to measure elevation deep inside a mountain near the France-Italy border. Although this elevation measurement is not as precise as ...

Kate Dignan has summited one 14er — she thinks it was probably Longs Peak, but she’s done her best to forget the experience. That trip, and countless photos from hikers around the state, got her ...

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate. In 2003, engineers from Germany and ...

CHICAGO--A Field Museum scientist has developed a novel way to determine land elevation as continents moved around the Earth through geological ages. Knowing how high mountains and plateaus were in ...

In a pioneering work, NASA scientists have fitted the laser-catching telescope of the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) into its place that will measure the elevation of Earth from ...

Washington: In a pioneering work, NASA scientists have fitted the laser-catching telescope of the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) into its place that will measure the elevation of ...

Eight hours after we stood on the roof of Washington last summer, our guides rewarded us with certificates that read “Mount Rainier, 14,410 feet.” Aware many others believe the mountain is actually a ...

New results from NASA’s MABEL campaign demonstrated that a photon-counting technique will allow researchers to track the melt or growth of Earth’s frozen regions. NASA’s Multiple Altimeter Beam ...

New results from NASA's MABEL campaign demonstrated that a photon-counting technique will allow researchers to track the melt or growth of Earth's frozen regions. When a high-altitude aircraft flew ...
