A historic image of Mercury, the first ever obtained from one spacecraft in orbit about the Solar System's innermost planet, was taken by NASA's MESSENGER probe on March 29, 2011, at 5:20 am EDT. MESSENGER then acquired an additional 363 images over six hours before sending back some of the date to Earth. Besides, it will continue to access 1,185 additional images in support of MDIS commissioning-phase activities over the next three days.
MESSENGER made a history when becoming the first spacecraft to orbit the planet Mercury on March 17, 2011. Its seven scientific instruments and radio science investigation will unravel the history and evolution of the Solar System's innermost planet during the one-year primary mission.
Now, let's unlock the secret of Mercury through some photos below.
