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 image: Wonders in the Antarctic sky

In 43 hours across five science flights in late November 2013, NASA's P-3 research aircraft collected more than 20,000 kilometers (12,000 miles) worth of science data. Instruments gathered information about the thickness ...

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. ...

Altimeter built at Goddard helped identify ice on Mercury

A Goddard-built instrument on NASA's MESSENGER mission provided one of three new lines of evidence that water ice exists near the north pole of Mercury. Most of the ice is covered by a thin layer of material that blankets ...
