In a few weeks, NASA's Operation IceBridge will take to the skies for another busy season of monitoring ice sheets, glaciers and sea ice from above. This year, the mission will be stationed in Antarctica for the first time, enabling scientists to conduct longer flights, and explore areas of the icy continent that were previously out of reach.

NASA's modified P-3B aircraft is scheduled to depart NASA's Wallops Flight Facility in Wallops Island, Va., on Nov. 11, and touch down at McMurdo Station in Antarctica later that week, Christy Hansen, IceBridge project manager at NASA's Goddard Space Flight Center in Greenbelt, Md., told reporters in a news briefing today (Oct. 29).

"Once we start getting into science data collection, we'll be able to collect more science data than when we were based in Chile," Hansen said.

Being stationed in Antarctica will also allow researchers to plan science flights that last up to eight hours, which means the aircraft will be able to cover more ground in some cases, enabling scientists to survey parts of Antarctica not visited on previous IceBridge missions.

Operation IceBridge was one of several Antarctic missions threatened by the recent shutdown of the U.S. federal government, which lasted from Oct. 1 through Oct. 16. During that time, about 800,000 federal employees were furloughed, including Michael Studinger, IceBridge's lead scientist at the Goddard Space Flight Center.

As a result, the status of the IceBridge mission was in limbo for some time, and despite weathering the political storm, Studinger said the government shutdown is expected to limit the amount of research that will be conducted this season.

"It put our preparations on hold for more than two weeks, and added some other headaches that we had to resolve," Studinger said. "We'll collect considerably less science data than we had planned for."

Chad Naughton, project manager for the National Science Foundation's (NSF) U.S. Antarctic Program in Centennial, Colo., said overcoming the effects of the shutdown was challenging, but he expects federally funded research in Antarctica to bounce back.

"We're all systems go for a lot of the good science that's coming down," Naughton said. "It seems annually there's always something that pops up that's a challenge that affects a lot of science and a lot of the logistics. This was a big one, but I think we got through it, and I think a lot of the science that NSF funds on an annual basis is going to continue."
