Craters Pop As NASA's Dawn Probe Approaches Ceres
astroengine writes New features on Ceres' icy surface are popping into view as NASA's Dawn spacecraft slowly spirals in on its final celestial target in the asteroid belt. Due to arrive in a stable Ceres orbit in March, the ion drive-propelled spacecraft is now less than 90,000 miles (145,000 kilometers) from its ultimate goal. Once arrived at Ceres, NASA will insert the probe into a highly stable orbit where, when the mission concludes in a year from now, Dawn will become a permanent man-made moon of the dwarf planet.
Actually, no, I had no idea what they meant until I got down into the comments. I assumed that craters were actually popping and was reading the summary trying to figure out if they were just observing some recurring natural phenomenon or if (far less likely) the probe itself was disrupting something on the surface.
