Since the magnitude 6.7 Northridge earthquake 20 years ago, researchers at Caltech have learned much more about where earthquakes are likely to happen, and how danger to human life and damage to property might be mitigated when they do occur.
South-central Idaho and the surface of Mars have an interesting geological feature in common: amphitheater-headed canyons. These U-shaped canyons with tall vertical headwalls are found near the Snake River in Idaho as well as on the surface of Mars, according to photographs taken by satellites.
Although researchers have determined the ages of rocks from other planetary bodies, the actual experiments—like analyzing meteorites and moon rocks—have always been done on Earth. Now, for the first time, researchers have successfully determined the age of a Martian rock—with experiments performed on Mars.
