NASA in Alaska 2014: MABEL: Welcome to Fairbanks!

July 14th, 2014 by Kate Ramsayer

Very few people get to fly 65,000 feet above Alaska’s glaciers. And even fewer get to fly over ones they share a name with. But on Friday, as pilot Denis Steele flew NASA’s ER-2 aircraft from Palmdale, California, to Fairbanks, Alaska, he snapped a picture of the scenery below – including Steele Glacier in the southwestern corner of Canada’s Yukon territory.

Steele and the ER-2 team, along with NASA scientists, engineers and others, are here in Fairbanks to fly a laser altimeter – MABEL, or Multiple Altimeter Beam Experimental Lidar – over melting summer sea ice, glaciers and more. It’s a campaign to see what these polar regions will look like with data from ICESat-2, once the satellite launches and starts collecting data about the height of Earth below. Gathering information now allows scientists to get a head start in developing the computer programs scientists will need to analyze ICESat-2’s raw data.

MABEL and other lidar instruments are flying on the ER-2, which provides a high-altitude perspective. In the next three weeks, the plan is to cover melting sea ice, glaciers, vegetation, lakes, and more.

Steele wasn’t the only one looking out of the plane windows on flights north. Kelly Brunt, a research scientist at NASA’s Goddard Space Flight Center, spotted a wildfire in Eastern Washington. The fire, burning in steep terrain, resembled an erupting volcano.

Over the weekend, the team settled into Fairbanks and a hangar at the U.S. Army’s Fort Wainwright, downloading data from the transit flight and ensuring the instruments are ready to fly when the weather allows. Cloudy skies over key sites means the ER-2 won’t fly today (Monday), but the team will check the weather tonight and see if it clears enough to fly the first science flight on Tuesday.
