The first close up look at Mercury

On 29th March, Tuesday NASA received the first close look at the hottest planet Mercury from the Messenger spacecraft, which entered orbit around Mercury on March 17. It has captured the areas around the planet's southern pole that have never been seen before and that could host water in the form of ice. It was soon followed by 363 more images over the next six hours.

Though it is too early to detail about the geological details based on this, but still there is a hope. As per mission tech leads, the Messenger spacecraft is set to circle Mercury for a year. It will survey the planet's hot, rocky surface, providing what scientists anticipate to be a wealth of information that has never before been gleaned from occasional glimpses caught from fly-by missions.
Even though Mercury sits blisteringly close to the sun, some areas in craters near its poles lie in permanent shadow and are probably cold enough to house ice deposits. Along with the search for water ice, the mission will map out the planet's surface, observe its magnetic fields and examine its surface composition.
