The Great Crater HokusaiExplanation: One of the largest young craters on Mercury, 114 kilometer (71 mile) diameter Hokusai crater's bright rays are known to extend across much of the planet. But this mosaic of oblique views focuses on Hokusai close up, its sunlit central peaks, terraced crater walls, and frozen sea of impact melt on the crater's floor. The images were captured by the MESSENGER spacecraft. The first to orbit Mercury, since 2011 MESSENGER has conducted scientific explorations, including extensive imaging of the Solar System's innermost planet. Now running out of propellant and unable to counter orbital perturbations caused by the Sun's gravity, MESSENGER is predicted to impact the surface of Mercury on April 30.

, as in the information brought up through the "impact the surface of Mercury" link it states "the highly successful orbital mission is about to come to an end, as the spacecraft runs out of propellant and the force of solar gravity causes it to impact the surface of Mercury, estimated to occur between 3:25 and 3:30 p.m. EDT on April 30, 2015" though adding "The uncertainties associated with low-minimum-altitude operations and near-zero amounts of usable spacecraft propellant introduce the potential for Mercury impact earlier in April or up to one 8.3-hour orbit later – just before midnight EDT on April 30, 2015" but even if that is the outcome it is still an amazing accuracy.
