Antarctica from Above

Antarctica from Above

In 2017, NASA's Operation IceBridge flew for the ninth year over Antarctica to map the ice. This video features photographs of land ice and sea ice, shot with a handheld camera and with the Digital Mapping System (DMS), during IceBridge flights in November 2017. Read more

Notes from the Field: ICESat-2 Antarctic Traverse

Notes from the Field: ICESat-2 Antarctic Traverse

In December 2017, NASA scientists begin an Antarctic traverse in giant snow machines along the line of latitude at 88°S. Ground-based measurements of the ice sheet’s elevation will be compared with measurements from ICESat-2 shortly after launch in 2018 to evaluate the satellite’s performance. Read more

The Rise and Fall of Africa’s Great Lake: Scientists Try to Understand the Fluctuations of Lake Chad

The Rise and Fall of Africa’s Great Lake: Scientists Try to Understand the Fluctuations of Lake Chad

More than 30 million people in Africa depend on Lake Chad for fresh water. But satellite and ground-based data show that the once-great lake now spans less than a tenth of the area it covered in the 1960s. Read more

Autumn from Orbit

Autumn from Orbit

From the Great Lakes to the mountains of Sweden, satellites offer an incredible view of autumn in the northern hemisphere. Read more

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

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

Starting in August 2016, SPURS-2 scientists deployed a web of sensors to monitor part of the Pacific Ocean for an entire year. Now, scientists on board the R/V Roger Revelle have returned to sea to recover moorings and gear and to collect one final, intense snapshot of the ocean. Read more

Peering through the Sands of Time: Searching for the Origins of Space Archaeology

Peering through the Sands of Time: Searching for the Origins of Space Archaeology

In searching for lost cities and ancient travel routes, an unlikely band of scientists and explorers helped develop a new set of tools for archaeology. Read more

Argentina After Dark

Argentina After Dark

When viewed from a satellite in daylight, the landscape of central Argentina shows barely a sign of human settlement. But by night, the place could be mistaken for a game of luminescent connect-the-dots. Read more

NASA Earth Observatory Goes to the Beach

NASA Earth Observatory Goes to the Beach

Summer is beach season in the northern hemisphere. But even if you're a regular at your local swimming hole, you probably haven't seen too many beaches from this perspective. See the satellite and space-station views of various shorelines from across the United States. No sunblock necessary. Read more

California Rises from Drought

California Rises from Drought

A June snowstorm just topped off the already thick layer of white stuff atop the Sierra Nevada. California's snow water equivalent rose to a heaping 170 percent of normal. But not so long ago, the state was in the midst of a deep drought; its mountains were bare and brown, and water levels plummeted in reservoirs. Read more

A Celebration of Clouds (video)

A Celebration of Clouds (video)

Clouds can be a nuisance when scientists are trying to observe features on Earth's surface. But at other times, clouds are exactly what they want to see. These images highlight some of the more unusual and beautiful clouds observed in recent years from space. Read more

Earth at Night

Earth at Night

Satellite images of Earth at night have been a curiosity for the public and a tool of fundamental research for at least 25 years. They have provided a broad, beautiful picture, showing how humans have shaped the planet and lit up the darkness. Read more

EO-1: 17 Images from 17 Years

EO-1: 17 Images from 17 Years

Since 2000, Earth Observing-1 has provided stunning views of our planet in its beauty and fury, while advancing satellite technology and imaging. The satellite is being turned off, but its legacy lives on. Read more

World of Change: Sprawling Shanghai

World of Change: Sprawling Shanghai

If you could go back in time to the 1980s, you would find a city that is drastically different than today’s Shanghai. Read more

El Niño: Pacific Wind and Current Changes Bring Warm, Wild Weather

El Niño: Pacific Wind and Current Changes Bring Warm, Wild Weather

El Niño is one of the most important weather-producing phenomena on Earth. The changing ocean conditions disrupt weather patterns and marine life in the Pacific and around the world. Satellites are unraveling the many traits of this wild child of weather. Read more

Notes from the Field: Sea to Space Particle Investigation

Notes from the Field: Sea to Space Particle Investigation

The month-long campaign across the Pacific on the R/V Falkor will monitor the diversity of oceanic phytoplankton, microscopic plant-like organisms, and their impact on the marine carbon cycle. Novel measurements will be compared to satellite observations and used in the formulation of the upcoming Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission. Read more
