New Study Brings Antarctic Ice Loss Into Sharper Focus

A NASA study based on an innovative technique for crunching torrents of satellite data provides the clearest picture yet of changes in Antarctic ice flow into the ocean. The findings confirm accelerating ice losses from the West Antarctic Ice Sheet and reveal surprisingly steady rates of flow from its much larger neighbor to the east. News Article Type: Homepage...

NASA's James Webb Space Telescope to Reveal Secrets of the Red Planet

The planet Mars has fascinated scientists for over a century. Today, it is a frigid desert world with a carbon dioxide atmosphere 100 times thinner than Earth’s. But evidence suggests that in the early history of our solar system, Mars had an ocean’s worth of water. NASA’s James Webb Space Telescope will study Mars to learn more about the planet’s transition from wet to dry, and what...

NASA's GOLD Mission to Explore Earth's Ionosphere Set for Launch Jan. 25

Like Earth, space has weather. Except instead of swirling winds and downpours of precipitation, space weather is defined by shifting electric and magnetic fields and rains of charged particles. At the very beginning of space, starting just 60 miles above Earth’s surface, there’s a layer of the atmosphere that shifts and changes in concert with both types of weather. News Article...
