IceBridge launches two sets of antarctic flights

Scientists with NASA's longest-running airborne mission to map polar ice, Operation IceBridge, completed a successful science flight on Oct. 29, inaugurating their 2017 survey of Antarctic sea and land ice. For the first ...

NASA's aerial survey of polar ice expands its Arctic reach

For the past eight years, Operation IceBridge, a NASA mission that conducts aerial surveys of polar ice, has produced unprecedented three-dimensional views of Arctic and Antarctic ice sheets, providing scientists with valuable ...

NASA technologists embrace laser instrument challenge

In 2007, the National Research Council threw down a challenge: Design a space-based laser altimeter that could measure the height of Earth's surface everywhere to within a mere 10 centimeters—all at 5-meter resolution. ...

New 2013 phases of the Moon animation released

New study maps Himalayan glacier behaviour

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, ...

Asteroid strikes cause the Moon's surface to smooth

The lunar surface is marred by impact craters, remnants of the collisions that have occurred over the past 4.5 billion years. The Orientale basin, the Moon's most recently formed sizeable crater, stands out from the rest. ...

Greenland's current loss of ice mass

The Greenland ice sheet continues to lose mass and thus contributes at about 0.7 millimeters per year to the currently observed sea level change of about 3 mm per year. This trend increases each year by a further 0.07 millimeters ...

Daybreak at Gale crater

This computer-generated images depicts part of Mars at the boundary between darkness and daylight, with an area including Gale Crater, beginning to catch morning light.

NASA details achievements of Lunar Reconnaissance Orbiter
