Answer to Question 1

A new spacecraft called MESSENGER (Mercury Surface, Space ENvironment, Eochemistry, and Ranging) passed Mercury three times and then entered orbit around the planet in 2011 . It has so far provided extensive photography of Mercury's surface as well as detailed measurements of Mercury's physical properties.

MESSENGER spacecraft found a magnetic field only about 1.1 percent as strong as Earth's.

MESSENGER imaged surface hollows in many locations that may indicate a substantial amount of volatiles were incorporated in the crust and subsequently vaporized.
