Lunar Orbit 2′s primary function was documenting areas of the moon that would be most hospitable to the Apollo and Surveyor missions. During its run, it returned a total of 609 high resolution images and 208 medium-sized frames. This includes the Copernicus crater (pictured below) which is considered by many to be the Picture of the Century.
While the spacecraft was intentionally downed on October 11, 1967, scientists had yet to find the crash site–til now.
The wreckage is thought to have been located by the Lunar Reconnaissance Orbiter (LRO) which is currently mapping the lunar surface in unprecedented detail. During its mission so far, the spacecraft has gathered more than 192 terabytes of data; that’s nearly 41,000 DVDs worth of data, images and maps! One of its key findings is our solar system’s coldest spot: a crater near the moon’s north pole was recorded at minus 415 degrees Fahrenheit. Brrr!Photo via NASA
