MESSENGER’s final image from Mercury
Here is the final image acquired and transmitted back to Earth by the MESSENGER spacecraft on April 30, 2015, shortly before it struck the planet. MESSENGER spent over four years orbiting Mercury. The image is located within the floor of the 93-kilometer-diameter crater Jokai. The spacecraft struck the planet just north of Shakespeare basin.
The MESSENGER mission was planned originally for a one-year orbit around Mercury. NASA said:
As the first spacecraft ever to orbit Mercury, MESSENGER revolutionized our understanding of the solar system’s innermost planet, as well as accomplished technological firsts that made the mission possible.
