The Ranger 9
The Ranger 9 was one of the last spacecraft to be launched in the 1960s. The Ranger 9 was created by Jet Propulsion Laboratory to take pictures of the Lunar Surface then crash into the Alphonsus crater on the moon.
Before, crashing the Ranger 9 took roughly 6,000 (5,814) photos of the moon in 20 minutes. The Ranger 9 spacecraft carried six television vidicon cameras, 2 full-scan cameras and 4 partial scan cameras to accomplish these objectives.
NASA built the Ranger 9 because NASA thought the Alphonsus crater recently was hosted lunar volcanic activity.
The Ranger 9 led to the understanding of the moon's mass and lead to the discovery that the moon's center of mass is displaced from its geometric center
The Alphonsus Craters Name
The Alphonsus crater is named after King Alfonso X of Castile(also known as the Wise, Spanish: el Sabio; November, 23, 1221 – April, 4, 1284). He fostered the development of a cosmopolitan court that encouraged learning. He was a king that liked astronomy.
