Vallis Schröteri is geologically fascinating because not only is it the largest lunar sinuous rille, it is composed of the primary rille and a smaller, inner rille. Image width is 1.5 km.
So that's what you think it is? Seems plausible. Interesting photograph either way. Any higher resolution versions?
In 2010, nearly forty years after the 1971 loss of signal from Lunokhod 1, the NASA Lunar Reconnaissance Orbiter photographed its tracks and final location, and researchers, using a telescopic pulsed-laser rangefinder, detected the robot's retroreflector.[2]
Lunokhod 2 operated for about 4 months, covered 37 km (23 miles) of terrain, including hilly upland areas and rilles, and sent back 86 panoramic images and over 80,000 TV pictures. The 37 km journey remains the longest any robotic rover has ever been driven on another celestial body. Many mechanical tests of the surface, laser ranging measurements, and other experiments were completed during this time.
