A massive impact on the Moon about 4 billion years ago left a 2,500-mile crater, among the largest known craters in the solar system. Smaller subsequent impacts left craters within that crater. Comparing the spectra of light reflected from the peaks of those craters may yield clues to the composition of the Moon’s lower crust and mantle — and would have implications for models of how the Moon formed.
PROVIDENCE, R.I. [Brown University] — Researchers from Brown University and the University of Hawaii have found some mineralogical surprises in the Moon’s largest impact crater. (more…)
PASADENA, Calif. — A NASA spacecraft is providing new evidence of a wet underground environment on Mars that adds to an increasingly complex picture of the Red Planet’s early evolution.
The new information comes from researchers analyzing spectrometer data from NASA’s Mars Reconnaissance Orbiter, which looked down on the floor of McLaughlin Crater. The Martian crater is 57 miles (92 kilometers) in diameter and 1.4 miles (2.2 kilometers) deep. McLaughlin’s depth apparently once allowed underground water, which otherwise would have stayed hidden, to flow into the crater’s interior. (more…)
