The moon's Tycho Crater, though average in size, is special because it appears to have formed relatively recently. The vast crater still looks pristine in the new images, while older craters are slowly covered by newer impacts as their features are obscured over the years.
To find the truth about Tycho's age, scientists will need rocks collected inside the crater. These may finally be available soon, since the site has been chosen as a possible landing spot for future manned missions to the moon in the 2020s under NASA's Constellation program.
