Scientists are using novel measurements of gravity to gather indispensable information about Earth’s water supplies. The GRACE mission can see water flowing underground. Read more

Notes from the Field Blog: Salinity Processes in the Upper Ocean Regional Study (SPURS)

Notes from the Field Blog: Salinity Processes in the Upper Ocean Regional Study (SPURS)

A group of scientists are headed to the saltiest spot in the North Atlantic Ocean. They will spend six weeks at sea studying what's driving changes in the salt content of the ocean and how these variations relate to an acceleration of the global water cycle and climate change. Read more

Greatest Hits from Landsat

Greatest Hits from Landsat

Landsat 1 was launched in July 1972, starting the longest continuous observation of Earth's land surfaces from space. Here are some of the memorable scientific and societal contributions from the 40-year-old program. Read more

Landsat Looks and Sees

The world’s longest-running Earth-observing satellite program has collected more than three million images, showing two generations of planetary evolution and of human imprints on Earth. The Landsat archives tell an unparalleled story of our land surfaces. Read more

Notes from the Field Blog: Siberia 2012 - Embenchime River Expedition

Notes from the Field Blog: Siberia 2012 - Embenchime River Expedition

A dedicated team of scientists has returned to the remote boreal forests of northern Siberia to study how the boreal ecosystem moderates Earth's climate by storing carbon and the implications of a warming climate on those forests. Read more

World of Change: Columbia Glacier, Alaska

World of Change: Columbia Glacier, Alaska

Since 1980, the volume of this glacier that spills into the Prince William Sound has shrunk by half. Climate change may have nudged the process along, but mechanical forces have played the largest role in the ice loss. Read more

Launched on May 4, 2002, NASA's Aqua satellite and its six instruments have provided a decade's worth of unprecedented views of our planet. Here are a few of our favorites. Read more

Where Is the Hottest Place on Earth?

Where Is the Hottest Place on Earth?

Satellite research shows that the world’s hottest spot changes, though the conditions don’t. Think dry, rocky, and dark-colored lands...and cities. Read more

Tohoku Earthquake and Tsunami: Looking Back from Space

Tohoku Earthquake and Tsunami: Looking Back from Space

In 2011, the fourth largest earthquake in history rocked the coast of Japan, spawning a devastating tsunami. Satellites and scientists had an unprecedented view of both. This gallery offers a glimpse of the broad scale of the destruction, of the recovery a year later, and of some new scientific understanding that emerged. Read more

Seeing Forests for the Trees and the Carbon:  Mapping the World’s Forests in Three Dimensions

Seeing Forests for the Trees and the Carbon: Mapping the World’s Forests in Three Dimensions

Earth has a carbon problem, and some think trees are the answer. Would it help to plant more? To cut down fewer? Does it matter where? Scientists are working to get a better inventory of the carbon stored in trees. Read more
