Orbiter Uncovers Mysteries of Martian Ice Cap
The Shallow Radar, or SHARAD, instrument aboard the Mars Reconnaissance Orbiter revealed subsurface geology allowing scientists to reconstruct the formation of a large chasm and a series of spiral troughs on the northern ice cap of Mars. The findings appear in two papers in the May 27 issue of the journal Nature.
“SHARAD is giving us a beautifully detailed view of ice deposits, whether at the poles or buried in mid-latitudes, as they changed on Mars over the last few million years,” said Rich Zurek, Mars Reconnaissance Orbiter project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, Calif.
