NASA Discovers Mega-Canyon Buried Under Ice

Hey Space Placers!

In my presentations to the public I often tell audiences that NASA does much that is not related to space.

The just announced discovery of a 460-mile mega-canyon buried under the ice sheet of Greenland is a case in point. Flying an Orion P-3B former anti-submarine/maritime patrol aircraft now fitted with  ice penetrating radar, NASA's Operation IceBridge that studies polar ice just announced the discovery.

The canyon is larger than the well known Grand Canyon and was discovered after decades of radar data was put together to reveal the giant structure. The canyon is thought to be similar to a river channel and predates the Greenland ice sheet.

Polar ice studies will continue and who knows what else will be discovered.
