Answer: Ranger 7
Today, with advanced technology such as the Lunar Reconnaissance Orbiter platform, we take high-resolution photos and a stunning video of the moon for granted. However, just over half a century ago we had not been able to get an intimate and close photo of the moon. All this changed in the 1960s.
In July 1964, NASA launched Ranger 7 on board an Atlas Agena B rocket. Ranger 7 was a lunar probe with a unique mission, and for the next three days she shot through space toward the moon, waiting to take action. As Ranger 7 approached the Moon on July 31
Ranger 7 was followed by Ranger 8 and Ranger 9, respectively. The overall cache of images from the three successful test missions provided 17,000 photos with previously unseen resolution and clarity.
