After a six-year mission to become to the first spacecraft to orbit Mercury, the MESSENGER has finally sent back some images from the closest planet to the Sun.
Yesterday afternoon, NASA released the first-ever image taken from a spacecraft in orbit around Mercury. The photo shows one of the planet's most famous craters: Debussy (the big white one, top right) and Matabei, which according to NASA has "unusual dark rays".
The MESSENGER (which stands for MEcury Surface, Space ENvironment, GEochemistry, and Ranging), which left Earth in 2004, has taken a number of images of Mercury during three previous flybys but has never gotten so close. It has since sent over 300 images that NASA will release at some point today.
