The day before the MESSENGER spacecraft impacted the surface of Mercury, the best prediction for the location and time of the impact was 54.4° N, 210.1° E, on 30 April 2015 at 19.26:02 UTC, as shown in the featured image of that day.  In the last month since impact, MESSENGER engineers have completed the final and most accurate determination of where the MESSENGER spacecraft impacted Mercury's surface. The determination indicates that the spacecraft impacted into a part of Mercury's surface that has a gradual incline with an approximate slope of 8.5°. The final estimate of the impact location is at 54.4398° N, 210.1205° E, and 2438.790 km from the center of Mercury. The final determination of the impact time is 19:26:01.166 UTC on 30 April 2015.  Traveling at 3.912 kilometers per second (8,750 miles per hour), the MESSENGER spacecraft is estimated to have created a crater 16 meters (52 feet) in diameter at this location. This new best determination of the impact location will help the next Mercury spacecraft to identify MESSENGER's crater, such as the joint ESA-JAXA BepiColombo mission, scheduled for lauch in 2017 and arrival in Mercury orbit in 2024.  Bottom Image Scale: This image is roughly 130 km (81 miles) across.  http://photojournal.jpl.nasa.gov/catalog/PIA19497

MESSENGER First Image after Closest Approach
Today, the MESSENGER spacecraft sent its final image.  Originally planned to orbit Mercury for one year, the mission exceeded all expectations, lasting for over four years and acquiring extensive datasets with its seven scientific instruments and radio science investigation. This afternoon, the spacecraft succumbed to the pull of solar gravity and impacted Mercury's surface. The image shown here is the last one acquired and transmitted back to Earth by the mission. The image is located within the floor of the 93-kilometer-diameter crater Jokai. The spacecraft struck the planet just north of Shakespeare basin.

Twins Image
NASA image acquired September 3, 2011  Dominici crater, the very bright crater to the top of this image, exhibits bright rays and contains hollows. This crater lies upon the peak ring of Homer Basin, a very degraded peak ring basin that has been filled by volcanism. This image contains several examples of craters that have excavated materials from depth that are spectrally distinct from the surface volcanic layers, providing windows into the subsurface. MESSENGER scientists are estimating the approximate depths of these spectrally distinct materials by applying knowledge of how impacts excavate material during the cratering process. The 1000, 750, and 430 nm bands of the Wide Angle Camera are displayed in red, green, and blue, respectively.  This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 250-meter/pixel (820 feet/pixel) morphology base map or the 1-kilometer/pixel (0.6 miles/pixel) color base map. It is not possible to cover all of Mercury's surface at this high resolution during MESSENGER's one-year mission, but several areas of high scientific interest are generally imaged in this mode each week.  The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. Visit the Why Mercury? section of this website to learn more about the key science questions that the MESSENGER mission is addressing. During the one-year primary mission, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.
