One Year Adrift, but Not Far

In July 2017, a huge iceberg dramatically broke away from the Larsen C Ice Shelf on the Antarctic Peninsula. But the aftermath has been a bit more drawn-out, as the berg hasn’t moved very far.

ICESat-2 Lasers Pass Final Ground Test

The next time lasers fire from NASA’s Ice, Cloud, and land Elevation Satellite-2, or ICESat-2, the spacecraft will be orbiting hundreds of miles above Earth and beginning its mission.

Emilia (Eastern Pacific Ocean)

NASA infrared data reveals Tropical Storm Emilia is strengthening.

Ramp-Up in Antarctic Ice Loss Speeds Sea Level Rise

ce losses from Antarctica have tripled since 2012, increasing global sea levels by 0.12 inch (3 millimeters) in that timeframe alone, according to a major new international climate assessment.

NASA’s ICESat-2 Arrives at Launch Site

NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) arrived at Vandenberg Air Force Base in California on Tuesday, June 12, three months before its scheduled launch.

Dirty, Crevassed Glaciers in Alaska

Over the years, scientists have captured spectacular photographs while mapping ice during NASA’s Operation IceBridge mission.

When Land Ice Meets Sea Ice

IceBridge scientists photograph icebergs encased in broken sea ice.

NASA Completes Survey Flights to Map Arctic Ice

Operation IceBridge, NASA’s longest-running airborne mission to monitor polar ice change, concluded this year’s springtime survey of Arctic sea and land ice on May 2.

NASA Scientist to Discuss 'Mapping the Blue Marble: Using Space-Based Observations for Improved Global Water Security and Sustainability' at Library of Congress Lecture

The public is invited to a free talk called 'Mapping the Blue Marble: Using Space-Based Observations for Improved Global Water Security and Sustainability,' with Dr. John Bolten.

Historic Low Sea Ice in the Bering Sea

In its annual rhythm of growth and melt, sea ice across the Arctic Ocean generally retreats throughout springtime. By the end of April 2018, ice cover in the Bering Sea was far below average...

Beauty in the Beaufort Ice Pack

On March 17, 2018, Arctic sea ice extent reached its annual peak; it was the second-lowest maximum on record.

Dividing Line

NASA's Operation IceBridge successfully collected data over several glaciers, research sites, and some parallel coastal grid lines on April 26, 2018, as part of its Spring 2018 campaign.

2020 Decadal Survey Missions: At a Glance

Any telescope that reaches the launch pad in the 2030s likely will look much different than the concepts four teams are currently studying to inform the 2020 Decadal Survey for Astrophysics, but the studies do offer a roadmap.

NASA Teams Study the Agency’s Future in Astrophysics; Tackle Formidable Technology Challenges

As in past decades, the agency won’t make that decision in a vacuum or without understanding the technical obstacles, which are formidable.

Curious Circles in Arctic Sea Ice

NASA’s Operation IceBridge—the airborne mission flown annually over both polar regions—is now in its tenth year making flights over the Arctic. That’s a lot of flight hours spent mapping the region.

Tendril of Ice in the Weddell Sea

Images from the coast of the Antarctic Peninsula show a curious phenomenon: what looks like a tendril of sea ice snaking away from the ice pack in the Weddell Sea.

NASA Renews Focus on Earth's Frozen Regions

In 2018, NASA will intensify its focus on one of the most critical but remote parts of our changing planet with the launch of two new satellite missions and an array of airborne campaigns.

Arctic Wintertime Sea Ice Extent Is Among Lowest On Record

Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.

NASA Begins Latest Airborne Arctic Ice Survey

Operation IceBridge, NASA's longest-running aerial survey of polar ice, has launched its tenth Arctic spring campaign.

Low Sea Ice Amid Arctic Warming

Arctic sea ice reaches its maximum extent each March. In February 2018, the average ice extent was the lowest of any February on record.

NASA Space Laser Completes 2,000-mile Road Trip

ICESat-2's laser instrument has shipped from NASA Goddard, where it was built and tested, to Arizona, where it will be assembled with its spacecraft.

An Icy Heart

The year 2017 was a record-breaking one for Operation IceBridge, NASA’s aerial survey of the state of polar ice.

Glaciers in the Tropics, but Not for Long

Though the Surdiman Range is located just south of the equator, the elevation is high enough and the air temperatures are cold enough to still support a few small areas of “permanent” ice

NASA’s Longest Running Survey of Ice Shattered Records in 2017

The year that recently ended was record-breaking for Operation IceBridge: for the first time in its nine-year history, the mission carried seven field campaigns in a single year.

Celebrating 60 Years of Groundbreaking U.S. Space Science

Sixty years ago, the U.S. launched Explorer 1, rocketing into the Space Age.
