Mission managers for NASA's Soil Moisture Active Passive (SMAP) observatory have determined that its radar, one of the satellite's two science instruments, can no longer return data.

Ice Loss From Jakobshavn Glacier As Seen From Space

Ice Loss From Jakobshavn Glacier As Seen From Space

Summer is the season to watch for ice loss from the outlet glaciers lining the perimeter of Greenland. JakobshavnGreenland's fastest-moving glacieris notorious for such losses; in 2014 the glacier shed kilometers of ice from its front.


Link Between Amazon Fires and Devastating Hurricanes

Link Between Amazon Fires and Devastating Hurricanes

Researchers from the University of California, Irvine and NASA have uncovered a remarkably strong link between high wildfire risk in the Amazon basin and the devastating hurricanes that ravage North Atlantic shorelines.


California Drought Causing Valley Land to Sink

California Drought Causing Valley Land to Sink

As Californians continue pumping groundwater in response to the historic drought, the California Department of Water Resources today released a new NASA report showing land in the San Joaquin Valley is sinking faster than ever before, nearly 2 inches (5 centimeters) per month in some locations.


Greenland - Lakes on a Glacier

Greenland - Lakes on a Glacier Video in Story

How deep is that icy blue water on Greenland's ice sheet? Dr. Allen Pope, of the National Snow and Ice Data Center, is using data from the NASA/USGS Landsat 8 satellite to find out.


Flooding in Myanmar Mapped From Orbit

Flooding in Myanmar Mapped From Orbit

Since mid-July, more than a million people have been severely affected by monsoon floods and landslides in Myanmar. What is the current situation?


Satellite Analysis of Typhoon Soudelor's Rainfall

Satellite Analysis of Typhoon Soudelor's Rainfall Video in Story

Typhoon Soudelor dropped over two feet of rainfall when it made landfall in China in early August, and soaked Taiwan. NASA estimated that rainfall using data from the Global Precipitation Measurement (GPM) mission.


First Use of ISS Astronaut Pictures for Light Pollution Studies

First Use of ISS Astronaut Pictures for Light Pollution Studies

Scientists are tapping into photographs taken by astronauts aboard the International Space Station (ISS) to reliably measure the amount of light pollution worldwide.


NASA Earth Observatory: Greater Denver and the Front Range

NASA Earth Observatory: Greater Denver and the Front Range

Astronauts on the International Space Station recognize the smooth, broad bend that separates mountains and plains as the Front Range of the Rocky Mountains. This sudden break between plains and mountains makes Denver one of the most spectacular cities in the United States.


In Africa, More Smoke Leads to Less Rain

In Africa, More Smoke Leads to Less Rain

The Moderate Resolution Imaging Spectrometer (MODIS) instrument on NASA's Aqua satellite captured this image of numerous fires burning in the transition zone between the Sahara Desert to the north and the greener savannas to the south.


DSCOVR Shows Moon Crossing Face of Earth

DSCOVR Shows Moon Crossing Face of Earth Video in Story

A NASA camera aboard the Deep Space Climate Observatory (DSCOVR) satellite captured a unique view of the moon as it moved in front of the sunlit side of Earth last month.


Europe's Latest Weather Satellite Delivers its First Image

Europe's Latest Weather Satellite Delivers its First Image

The European Space Agency (ESA) was responsible for the initial operations after launch (the so-called launch and early orbit phase) of MSG-4 and handed over the satellite to EUMETSAT on 26 July.

Cyclone Komen Approaching Bangladesh As Seen From Space

Composite image from 09:00 (UTC) on Wednesday 29 July 2015, shows tropical cyclone 02B (Two-15) in the Indian Ocean.


Satellite Data Used To Map Himalayan Glacier Behavior

Satellite Data Used To Map Himalayan Glacier Behavior

Glaciers are one of the largest reservoirs of freshwater on our planet, and their melting or growing is one of the best indicators of climate change. However, knowledge of glacier change has been hampered by lack of data, especially for understanding regional behaviour.


Earth From Space: Northern Italy

Lakes on the southern side of the Italian Alps are pictured in this early acquisition by the Sentinel-2A satellite.


California 'Rain Debt' Equal to Average Full Year of Precipitation

California 'Rain Debt' Equal to Average Full Year of Precipitation

A new NASA study has concluded California accumulated a debt of about 20 inches of precipitation between 2012 and 2015 -- the average amount expected to fall in the state in a single year.


Source of Soot Warming The Tibetan Plateau Has Been Identified

Source of Soot Warming The Tibetan Plateau Has Been Identified

Using a climate model that can tag sources of soot from different global regions and can track where it lands on the Tibetan Plateau, researchers have determined which areas around the plateau contribute the most soot -- and where.


Pinning Down The Cause of the Younger Dryas

Pinning Down The Cause of the Younger Dryas

At the end of the Pleistocene period, approximately 12,800 years ago -- give or take a few centuries -- a cosmic impact triggered an abrupt cooling episode that earth scientists refer to as the Younger Dryas.
