NASA is offering the public a front row seat for the total solar eclipse on Wednesday, March 29 thanks to a partnership with the University of California at Berkeley and San Francisco s Exploratorium.

NASA's Space Technology 5 successfully launched today at 9:04 a.m. EST, from Vandenberg Air Force Base, Calif., on a Pegasus XL rocket.

Move over, Superman, with your X-ray vision. Marine scientists have figured out a way to see through the ocean's surface and detect what's below, with the help of satellites.

A NASA-funded expedition to the Arctic to map the thickness of snow has a legion of unexpected furry fans hailing from one of the world's coldest regions: polar bears.

NASA scientists have found that a major form of global air pollution involved in summertime "smog" has also played a significant role in warming the Arctic.

A typical windy day can bring along with it more than just a tangle of leaves and a warm breeze. Pollution too is often transported by the same wind currents, and often wafts in from places like Mexico and Central America and from overseas across the Pacific Ocean. NASA researchers are using complex scientific instruments aboard aircraft to learn more about the air that blows in from Mexico City and other places to North America, and what pollutants may blow in with it. Perhaps most importantly, they are seeking answers to where this long-range air pollution may be headed.

In Mexico City, a team of researchers from NASA and other institutions have kicked off the first phase of one of the most complex field campaigns ever undertaken in atmospheric chemistry. Researchers will use data from research satellites, aircraft and ground-based instruments to investigate the transformation of air pollution as it flows downwind from Mexico City and learn more about impacts of air pollution on human health and climate.

Studies have shown that over the last 40 years, a warming climate has been accompanied by fewer rain- and snow-producing storms in mid-latitudes around the world, but the storms that are happening are a little stronger with more precipitation. A new analysis of global satellite data suggests that these storm changes are affecting strongly the Earth's water cycle and air temperatures and creating contrasting cooling and warming effects in the atmosphere.

In the most comprehensive survey ever undertaken of the massive ice sheets covering both Greenland and Antarctica, NASA scientists confirm climate warming is changing how much water remains locked in Earth's largest storehouses of ice and snow.

Scientists were able to conduct the first-ever gravity survey of the entire Antarctic ice sheet using data from the joint NASA/German Aerospace Center Gravity Recovery and Climate Experiment (GRACE). This comprehensive study found the ice sheet's mass has decreased significantly from 2002 to 2005.
