Photon Phriday' Digs Deep for Western U.S. SnowEx Campaign
Snow is vital for Earth’s ecosystems and humans, from its temperature-regulating reflection of sunlight and insulating properties, to its life-sustaining water as it melts in the springtime. Snow provides freshwater for drinking,...

NASA | Water on the Moon
Since the 1960's, scientists have suspected that frozen water could survive in cold, dark craters at the Moon's poles. While previous lunar missions have detected hints of water on the Moon, new data from the Lunar Reconnaissance Orbiter...

NASA | Scanning a Snow Storm
On March 17, 2014 the Global Precipitation Measurement (GPM) mission's Core Observatory flew over the East coast's last snow storm of the 2013-2014 winter season. This was also one of the first major snow storms observed by GPM shortly...

Weather Things: Weather Cycles
The orbit of Earth on a tilted axis around the sun leads to the seasons. The resulting change of angle of the sun, and length of day controls how warm we get at different times of the year. With those changes in seasons come changes in...

Arctic Sea Ice Continues a Trend of Shrinking Maximum Extents
Arctic sea ice reached its annual maximum extent on March 17, according to analysis by NASA and the National Snow and Ice Data Center. The 2018 extent reached 5.59 million square miles, only about 23,000 square miles larger than the...

NASA Views Laser Landscapes of Helheim Glacier
What if you could measure a glacier in such detail that you could visualize its surface in 3D? And what if you could compare that view with data from one, two, even 20 years ago? NASA airborne campaigns like Operation IceBridge have been...
