NASA scientists have finally acquired the new images of Mercury as their MESSENGER probe initiates a year-long mission for mapping the entire surface of the whole solar system's least-understood planet. It took an almost 7.9-billion-kilometer journey for the probe to reach its destination in around 6years and 6months as it finally entered the planet's orbit on March 17.

Mercury has a very unrealistic temperature range as it reaches 427 degrees Celsius in day-time with minus 150 degrees at night. Hence, Mercury is the least explored planet and also because it is the closest planet to the Sun which makes it a subject of enormous gravitational pulls and massively high levels of radiation.
