Improvements to Measuring the Ups and Downs of the Landscape
If you are a jazz fan, you may be familiar with Ella Fitzgerald singing ‘How deep is the ocean, how high is the sky’. Using data from the Shuttle Radar Topography Mission we now know how high the land really is.
Unlocking the Power of Synthetic Aperture Radar for Geosciences
Due to its unique ability to monitor Earth’s surface, Synthetic Aperture Radar plays a pivotal role in revolutionizing the geosciences.
A Cloud-Based Solution to a Radar Data Deluge
An open-science tool built to support NASA missions is making synthetic aperture radar, once the domain only of subject matter experts, more accessible for nonspecialists and real-world applications.
Putting Accessibility on the Map
New research demonstrates how to make radar maps more easily interpretable for people with color vision deficiency.
Lunar Lava Tube Revealed Beneath Collapsed Pit
The Sea of Tranquility is home to at least one lunar lava tube, which could preserve a pristine and unweathered record of lunar volcanism.
Saving the Planet with Radar Astronomy
Once the largest telescope in the world, Arecibo kept watch for dangerous asteroids using radar. With it gone, the world is preparing the next generation of radar observatories.
Radar Data Show Thwaites Gets a Daily Bath of Warm Seawater
The Doomsday Glacier, predicted to raise global sea level by more than half a meter, could be exposed to more warm ocean water than previously thought.
Phased-Array Radar Detection of Electrically Aligned Ice Crystals
A new method for observing electrically aligned ice crystals in localized storms can detect the onset of electrification and lightning in developing storms.
