NASA-Produced Damage Maps May Aid Mexico Quake Response

NASA/JPL-Caltech-produced map of damage in and around Mexico City from the Sept. 19, 2017.

A new NASA-produced map of areas likely damaged by the Sept. 19 magnitude 7.1 Raboso earthquake near Mexico City may help responders and groups supporting response efforts.



Wind, Warm Water Revved Up Melting Antarctic Glaciers

A rock outcropping on Fleming Glacier.

The flow speeds of Antarctica's fastest-accelerating glaciers in 2008-2014 likely increased because of warm water blown into their bay by La Niña and another climate pattern.

50 words for snow, or conceptual confusion

In a well-known and generally debunked story, Inuit people have around 50 words for snow. Or so the argument by anthropologist Franz Boas goes. In fact, people who engage with the phenomena of their environments often make distinctions that those who rarely or never engage in the same way with those phenomena don’t. Snow is Read More...

After Cassini: Pondering the Saturn Mission’s Legacy

Cassini's discoveries are feeding forward into future exploration of the solar system.

As the Cassini spacecraft nears the end of a long journey rich with scientific and technical accomplishments, it is already having a powerful influence on future exploration.



NASA/UCI Find Evidence of Sea Level ‘Fingerprints’

Sea level rise fingerprints calculated from observations of mass changes in Greenland, Antarctica

For the first time, scientists have detected sea level "fingerprints" -- patterns of variation in global sea level due to changes in water and ice on land -- in GRACE data.
