Without any atmosphere, the tracks and other items have remained undisturbed over the 40 years since we last set foot on the moon. “We can retrace the astronauts’ steps with greater clarity to see where they took lunar samples,” said Noah Petro, a lunar geologist at NASA’s Goddard Space Flight Center in Greenbelt, Md., who is a member of the LRO project science team.
The images show not only paths made by the lunar exploration vehicles but also the trails left in the moon’s thin soil when the astronauts exited the lunar modules and explored on foot. In the Apollo 17 image, the foot trails, including the last path made on the moon by humans, are easily distinguished from the dual tracks left by the lunar rover, which remains parked east of the lander.
“The new low-altitude Narrow Angle Camera images sharpen our view of the moon’s surface,” said Arizona State University researcher Mark Robinson, principal investigator for the Lunar Reconnaissance Orbiter Camera (LROC). “A great example is the sharpness of the rover tracks at the Apollo 17 site. In previous images the rover tracks were visible, but now they are sharp parallel lines on the surface.”
