Nimbus' 40th Anniversary

On August 28, 2004, NASA celebrated the 40th anniversary of the launch of the Nimbus-1 Earth-observation satellite. Starting in 1964 and for the next twenty years, the Nimbus series of missions was the United States' primary research and development platform for satellite remote-sensing of the Earth. Read more

Time on the Shelf

Time on the Shelf

Twenty-five years of NASA scientists' research in Antarctica and Greenland show that even huge ice sheets can change more quickly than scientists thought, causing sea level to rise. Read more

The Rising Cost of Natural Hazards

The Rising Cost of Natural Hazards

Disaster-related economic losses topped $145 billion in 2004, the latest in a disturbing upward trend. Has climate change increased the number and severity of natural disasters, or is the rising cost of natural disasters due to other human factors? Read more

Stealing Rain from the Rainforest

Stealing Rain from the Rainforest

In a rainforest, visible effects of drought can be subtle. An experiment that mimicked the impact of a severe El Nino in the Amazon revealed surprising signs of stress that could be seen from space. Read more

Terra Turns Five

Terra Turns Five

In February 2000, NASA's Terra satellite began measuring Earth's vital signs with a combination of accuracy, precision, and resolution the world had never before seen. While the mission is still in the process of fulfilling its main science objectives, Terra's portfolio of achievements to date already marks the mission a resounding success. Read more

Polar Wind Data Blow New Life Into Forecasts

Polar Wind Data Blow New Life Into Forecasts

Where real-world weather observations are scarce, scientists are estimating winds by tracking the movement of clouds and water vapor between consecutive Terra and Aqua satellite images. In a new Earthsky podcast, atmospheric scientist Jeff Key talks about how the technique has improved forecasts and what will happen when these NASA missions reach their end. Read more
