On July 30, 1971, Apollo 15 landed on the moon. During their 67 hours on the lunar surface, commander Dave Scott and LM Pilot Jim Irwin spent 18 and a half hours exploring the landscape.
They traveled more than 17 miles thanks to the Lunar Rover, and returned almost 168 pounds of samples from dark planes, lunar highlands, and winding valleys from the Hadley-Appenine region. For Scott the mission was a striking success, especially compared to his first spaceflight on Gemini 8.
Gemini 8 was the sixth manned mission of ten in the program designed to work out the kinks of a lunar mission. Every mission built on what the previous one had accomplished.
For command pilot Neil Armstrong and pilot Scott, the primary mission objective was to make the first rendezvous and docking in orbit with the unmanned Agena target vehicle.
On the morning of March 16, 1966, NASA launched the Agena flawlessly at 9:00. Armstrong and Scott followed in Gemini 8 at 10:41. For six hours and 33 minutes, nothing out of the ordinary happened.
