Mapping hidden meltwater paths in glaciers

Norwegian and Estonian researchers have developed a method to map hidden meltwater paths in glaciers. Having a better understanding of how water moves inside and under the glaciers helps to better predict the motion, melting ...

NASA laser reflector for ESA satnav on Lunar Pathfinder

NASA has delivered a retroreflector array to ESA that will allow the Lunar Pathfinder mission to be pinpointed by laser ranging stations back on Earth as it orbits the moon. Such centimeter level laser measurements will serve ...

Drones help calibrate radio telescope at Brookhaven Lab

Cosmologists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are experimenting with a prototype radio telescope, called the Baryon Mapping Experiment (BMX). Built at the Lab in 2017, the prototype ...

GPS helping provide more precise precipitation predictions

Scientists are using GPS signals to measure air moisture for better weather forecasting. The method is now being incorporated into the Bureau of Meteorology's weather forecast models following successful tests over Australia, ...

NASA small satellites can aid hurricane forecasts with GPS

Eight briefcase-size satellites flying in a row may be key to improving forecasts of a hurricane's wind speed—detecting whether it will make landfall as a Category 1 or a Category 5. NASA's Cyclone Global Navigation Satellite ...

Satellites assisting look into hurricanes

A mission to probe winds deep inside hurricanes, where most satellites cannot see and few aircraft venture, is showing signs of success despite an unexpected obstacle linked to tensions in the Middle East.

Every bat travels differently

The females of some bat species migrate hundreds of kilometers after hibernation to give birth to their offspring in insect-rich regions. Unlike birds, it is largely unknown how bats keep their energy consumption low during ...
