EarthNASA’s GRACE: What We’ve Learned from Water in Motion
When you hear news about ice loss from Greenland or Antarctica, an aquifer in California that is getting depleted, or a new explanation for a wobble in Earth’s rotation, you might not realize that all these findings may rely on data from one single mission: the U.S.-German Gravity Recovery and Climate Experiment (GRACE). GRACE data, …
MoonStudy Finds New Wrinkles on Earth’s Moon
Billions of years ago, Earth’s Moon formed vast basins called “mare” (pronounced MAR-ay). Scientists have long assumed these basins were dead, still places where the last geologic activity occurred long before dinosaurs roamed Earth. But a survey of more than 12,000 images reveals that at least one lunar mare has been cracking and shifting as …
MarsWhy This Martian Full Moon Looks Like Candy
For the first time, NASA’s Mars Odyssey orbiter has caught the Martian moon Phobos during a full moon phase. Each color in this new image represents a temperature range detected by Odyssey’s infrared camera, which has been studying the Martian moon since September of 2017. Looking like a rainbow-colored jawbreaker, these latest observations could help …
EarthOCO-3 Ready to Extend NASA’s Study of Carbon
Updated at 12:35 a.m. PDT (3:35 a.m. EDT) on May 10 NASA’s OCO-3 was removed from the Dragon spacecraft and robotically installed on the exterior of the space station’s Japanese Experiment Module-Exposed Facility as of approximately 9 p.m. PDT on May 9 (12 a.m. EDT on May 10). Over the next two days, a functional …
AsteroidsNASA’s First Planetary Defense Technology Demonstration to Collide with Asteroid in 2022
The Double Asteroid Redirection Test (DART) – NASA’s first mission to demonstrate a planetary defense technique – will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos. The asteroid poses no threat to Earth and is an ideal test target: measuring the change in how the smaller asteroid …
MarsFor InSight, Dust Cleanings Will Yield New Science
The same winds that blanket Mars with dust can also blow that dust away. Catastrophic dust storms have the potential to end a mission, as with NASA’s Opportunity rover. But far more often, passing winds cleared off the rover’s solar panels and gave it an energy boost. Those dust clearings allowed Opportunity and its sister …
EarthNASA’s AIRS Images Cyclone Fani Before Landfall
This image shows Tropical Cyclone Fani just off the east coast of India in the Bay of Bengal. NASA’s Atmospheric Infrared Sounder (AIRS) collected the image at about 1 p.m. PDT (4 p.m. EDT) today, May 2. At the time, the cyclone’s wind speeds were equivalent to a Category 4 hurricane, with maximum sustained winds …
MarsMartian Dust Could Help Explain Water Loss, Plus Other Learnings From Global Storm
Dust is not just a household nuisance; it’s a planetary one, particularly on Mars. Before astronauts visit the Red Planet, we need to understand how the dust particles that often fill the atmosphere could impact them and their equipment. The global Martian dust storm of summer 2018 — the one that blotted out sunlight for …
EarthData with Flippers? Studying the Ocean from a Seal’s POV
Scientist Lia Siegelman is using a surprising data source to study the ocean around Antarctica — one that has flippers and bears a passing resemblance to Jabba the Hut. Siegelman is using data from a single tagged southern elephant seal to study small-scale ocean features in a little-known part of the ocean around Antarctica. She …
