NASA Helps See Buried Mars Flood Channels in 3-D
This illustration
schematically shows where the Shallow Radar instrument on NASA's Mars
Reconnaissance Orbiter detected flood channels that had been buried by
lava flows in the Elysium Planitia region of Mars.
March 07, 2013
The spacecraft took numerous images during the past few years that showed channels attributed to catastrophic flooding in the last 500 million years. During this period, Mars had been otherwise considered cold and dry. These channels are essential to understanding the extent to which recent hydrologic activity prevailed during such arid conditions. They also help scientists determine whether the floods could have induced episodes of climate change.
The estimated size of the flooding appears to be comparable to the ancient mega-flood that created the Channeled Scablands in the Pacific Northwest region of the United States, in eastern Washington.
