Exploration of the Moon Exploration of the Moon The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his
Craters of the Moon National Monument and Preserve system' that Craters of the Moon, Kings Bowl, and Wapi lava fields were created. The Great Rift is a National Natural Landmark. In spite of their fresh appearance, the oldest flows in the Craters of the Moon Lava Field are 15,000 years old and the youngest erupted about 2000 years ago, according to Mel Kuntz and other USGS geologists. Nevertheless, the volcanic fissures at Craters of the Moon are considered to be dormant, not extinct, and are expected to erupt in less than a thousand years. There are eight major eruptive periods recognized in the Craters of the Moon Lava
