HTTP:: MRO Images Martian North Pole Ice Layers
--------
NASA's Mars Reconnaissance Orbiter (MRO) is the most active probe sent to the Red Planet to date. Up until now, it has sent back the most pieces of information on the planet of all missions, and continues to do so at a steady rate, in spite of occasional glitches and reboots. Recently, with the help of one of its advanced instruments, it imaged the layers of ice at the Martian North Pole, and successfully evidenced the fact that geological records were in tune with theoretical-model climate swings during the past few million years, experts at the Jet Propulsion Laboratory, (JPL), in Pasadena, California, report. According to the measurements, the ice layers stack up neatly on top of each other, and have grown to be two kilometers (1.2 miles) in height. The patterns in which they are arranged offer insight into how they were formed, the JPL team says. Coupled with theoretical models of climate-change cycles on Mars, the new images can lead to a better understanding of how !
the climate on the planet looked like a few million years ago. The deposits cover an overall area that is roughly one third larger than Texas. “Contrast in electrical properties between layers is what provides the reflectivity we observe with the radar. The pattern of reflectivity tells us about the pattern of material variations withi...
