Ms. Pacman Arrives on Mercury
This high-resolution NAC image gives us another glimpse at Ailey, one of the 23 Mercury craters named in April 2012. The area surrounding these craters, the continuous ejecta blanket, is very smooth. A continuous ejecta blanket is the area immediately surrounding an impact that is entirely covered by debris from the collision. In Ailey's case, the ejecta blanket appears smooth because any roughness in the previously existing terrain was filled in by the pulverized falling debris. This scene includes a crater that was partially buried by Ailey's impact, making it faintly resemble Ms. Pacman.
