Antarctica’s Tallest Peak

NASA’s DC-8 flying laboratory passes Antarctica’s tallest peak, Mount Vinson, on Oct. 22, 2012, during a flight over the continent to measure changes in the massive ice sheet and sea ice. The flight is part of NASA’s Operation IceBridge, a multi-year airborne campaign to monitor changes in Earth’s polar ice caps in both the Antarctic and Arctic. IceBridge science flights from Punta Arenas, Chile, began on Oct. 12 and continue through early November. Mount Vinson is located in the Sentinel Range of the Ellsworth Mountains in Antarctica.

ESA Euronews: Measuring earth’s vital magnetic field

Earth's magnetosphere is an invisible shield, protecting our planet from harmful solar radiation. Many living organisms - from bacteria to insects or birds - seem to rely on Earth's magnetic field to navigate. Man has been doing so for a thousand years since the invention of the compass. But research shows the magnetic field is weakening and scientists are trying to understand why.

Some believe it signals a pole reversal in progress, not an uncommon phenomenon in the history of our planet. As ground observatories fail to grasp the whole picture, we are sending magnetometers into orbit to try to measure the magnitude and the direction of the magnetic field. Find out more, this week, in Space.

Thule boilers save big in first year

In 2011, five exhaust boilers were installed at Thule Air Base, Greenland, to decrease the amount of JP-8 fuel used for heating the base and ultimately, save money.

Thule has five locomotive-style engines in its M-Plant that generate electricity for the base, according to Randy Pieper, 21st Civil Engineer Squadron resource efficiency manager.

The electrical generators are only 35 to 40 percent efficient, he said, and most of the energy produced is wasted through exhaust heat.
