Long Ago, Mercury Probably Harbored a Vast Magma Ocean

  Massive lava flows may have given rise to two distinct rock types on Mercury’s surface   By analyzing Mercury’s rocky surface, scientists have been able to partially reconstruct the planet’s history over billions of years. Now, drawing upon the chemical composition of rock features on the planet’s surface, scientists at MIT have proposed that [continue reading]

Characterizing the Surface Composition of Mercury

NASA’s MESSENGER (MErcury Surface, Space Environment, GEochemistry, and Ranging) spacecraft, which has been orbiting Mercury since March 2011, has been revealing new information about the surface chemistry and geologic history of the innermost planet in the Solar System. Mercury, as taken from the spacecraft MESSENGER. The spacecraft captured nearly 100,000 images as it orbited the planet. [continue reading]
