NeRD

6 min read Quantum Sensing via Matter-Wave Interferometry Aboard the International Space Station Future space missions could use quantum technologies to help us understand the physical laws that govern the universe, explore the composition of other planets and their moons, gain insights into unexplained cosmological phenomena, or monitor ice sheet thickness and the amount of water in underground aquafers on Earth. Upgraded hardware being prepared at Jet Propulsion Lab for launch and install into the Cold Atom Lab on the International Space Station. The Science Module in the background enables…

4 min read NASA Satellites Reveal Abrupt Drop in Global Freshwater Levels Earth (ESD) Earth Home Explore Climate Change Science in Action Multimedia Data For Researchers GRACE satellites measure gravity as they orbit the planet to reveal shifting levels of water on the Earth (artist’s concept). NASA/JPL-Caltech An international team of scientists using observations from NASA-German satellites found evidence that Earth’s total amount of freshwater dropped abruptly starting in May 2014 and has remained low ever since. Reporting in Surveys in Geophysics, the researchers suggested the shift could indicate Earth’s…

NASA-Funded Studies Explain How Climate Is Changing Earth’s Rotation

NeRD

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Arctic is captured in this 2010 visualization using data from NASA’s Aqua satellite. A new study quantifies how climate-related processes, including the melting of ice sheets and glaciers, are driving polar motion. Another study looks at how polar meltwater is speeding the lengthening of Earth’s day. NASA’s Scientific Visualization Studio Researchers used more than 120 years of data to decipher how melting ice, dwindling groundwater, and rising seas are nudging the planet’s spin axis and lengthening days. Days…
