South Sudan Submerged

Three extreme rainy seasons in a row have pushed rivers and wetlands to heights not seen in decades.

Disappearing Lake Tuz

Once the second-largest lake in Turkey, it now rarely spans an area much larger than a puddle.

Soggy Autumn in the Pacific Northwest

Soils across western Washington and southern British Columbia were saturated for much of the season.

NASA to Highlight New Science Findings, Missions During AGU Meeting

NASA researchers and colleagues from around the world will present the latest findings on a range of Earth and space science topics at the annual American Geophysical Union (AGU) meeting, being held virtually and in New Orleans from Monday, Dec.13, through Friday, Dec. 17.

One Year From Launch: US-European Satellite to Track World’s Water

An international team of engineers and technicians has finished assembling a next-generation satellite that will make the first global survey of Earth’s surface water and study fine-scale ocean currents. The Surface Water and Ocean Topography (SWOT) mission is just a year out from launch, and the final set of tests on the spacecraft have started.

6 Things to Know About Supercomputing at NASA

From exploring the solar system and outer space to improving life here on Earth, supercomputing is vital to NASA missions.

Vice President Harris to Visit NASA Goddard Today, Deliver Live Remarks

Vice President Kamala Harris will visit NASA’s Goddard Space Flight Center in Greenbelt, Maryland today, Nov. 5, to get a firsthand look at the agency’s work to combat the climate crisis and protect vulnerable communities.

NASA Partnership Supports the Next Generation of Space and Science Professionals

NASA's participation in the Mentoring365 program will provide connectivity and access to the next generation of space and science professionals.

The Most Important Instrument You’ve Never Heard of

For a little-known satellite instrument, the microwave sounder has a major impact on our lives. These instruments feed the weather models that inform our daily forecasts and help us plan for extreme weather. And their long-term temperature records of our atmosphere have played a key role in helping scientists determine that humans ...

Lake Powell Reaches New Low

Water levels at Glen Canyon Dam have fallen to their lowest level since 1969 and are still dropping

Drought Makes its Home on the Range

Drought is a natural part of the climate cycle, but as Earth’s atmosphere continues to warm due to climate change, droughts are becoming more frequent, severe and pervasive. Ranchers throughout the U.S. are using data from NASA and others to care for their herds and the land during drought conditions.

NASA Watches Water to Help Grow our Groceries

If you ate a fruit, vegetable or nut today, chances are good that it came from California’s Central Coast or the nearby Central Valley.

Evapotranspiration: Watching Over Water Use

As soil and other surfaces dry, water is transferred into the air as water vapor. That is evaporation. Plants actively release water, moving it out of their leaves and stems and into the drier air. That is transpiration. Combine the two and that's evapotranspiration – the process through which water leaves plants, soils and other surfaces.

Earthquake in Haiti Triggers Landslides

A break in the clouds offered satellites a view of hillslopes that slid away during the magnitude 7.2 temblor.

Eos Magazine Highlights NASA’s Groundbreaking Landslide Innovations

Advancements by the landslides team at NASA’s Goddard Space Flight Center are featured in a new science update published in the American Geophysical Union’s (AGU) science news magazine, Eos.

Drought in Madagascar

The lack of rainfall and other environmental factors have taken a toll on the region’s vegetation and agricultural production, leaving many in the region facing severe hunger.

Flooding in Central China

A slow-moving rainstorm overwhelmed rivers and reservoirs, leading to deadly flooding in the province of Henan.

From Seed to Market: NASA Brings Food to the Table

As the seasons turn from spring, to summer, to fall – farmers plant crops, monitor their growth and harvest them. And now increasingly they are using NASA Earth science data to help make their decisions. While NASA satellites primarily support scientific understanding, the data can also be applied for societal benefits like agriculture.

Deadly Floods Surprise Europe

Flash floods have devastated several communities in Germany, Belgium, and The Netherlands.

California Reservoirs Reflect Deepening Drought

Precipitation totals and lake levels are among the worst they have been since the 1970s.

NASA Snow Campaign Wraps for 2021

SnowEx teams measured snow at six sites across the Western U.S., on the ground and with drones and airplanes. This information is crucial for managing water resources for drinking, agriculture, hydropower, drought and more.

Machine Learning Model Doubles Accuracy of Global Landslide ‘Nowcasts’

LHASA Version 2, released last month along with corresponding research, is a machine-learning-based model that analyzes a collection of individual variables and satellite-derived datasets to produce customizable ‘nowcasts’

NASA Scientists Available for Interviews Throughout Hurricane Season

June 1 marked the official start of the Atlantic hurricane season, which officially ends Nov. 30.

Científicas de la NASA disponibles para entrevistas durante la temporada de huracanes

El 1 de junio marcó el inicio oficial de la temporada de huracanes en el Atlántico, que termina oficialmente el 30 de noviembre.

Satellites Show How Earth’s Water Cycle Is Ramping Up as Climate Warms
