New Topographic Map of Moon

Let's first see how LOLA (Lunar Orbiter Laser Altimeter) works. LOLA sends a pattern of five laser pulses to the lunar surface, and computes distance and elevation by measuring how long takes for the pulses to return. Credit: NASA/Goddard/Chris Meaney

Now check new topographic map comparing to an old one - much better!
