Apollo 15: 'Never Been on a Ride like this Before'

Our first wheels on the moon. On the Apollo 15 mission, the lunar roving vehicle allowed the astronauts to cover a much greater distance on the moon than the previous three flights had accomplished.

This year marks the 50th anniversary of the Apollo 15 mission. On July 26, 1971, David Scott, commander; Jim Irwin, lunar module pilot; and Al Worden, command module pilot launched from Kennedy Space Center's Launch Complex 39A.

Apollo 15 set several new records for crewed spaceflight:

• heaviest payload in a lunar orbit of approximately 107,000 pounds
  
• maximum radial distance traveled on the lunar surface away from the spacecraft of about 17.5 miles
  
• most lunar surface moonwalks (three)
  
• longest total of duration for lunar surface moonwalk (18 hours, 37 minutes)
  
• longest time in lunar orbit (about 145 hours)
  
• longest crewed lunar mission (295 hours)
• longest Apollo mission
  
• the first satellite placed in lunar orbit by a crewed spacecraft, and
  
• first deep space and operational spacewalk.

Apollo 12, because its pinpoint landing set the stage for targeting all remaining Apollo missions.

Apollo 15 because of its location and crew. For such a geologically varied site (mountains, mare, and a rille!) to be explored by the most competent crew of non-professional geologists was a match of epic proportions. Plus that site was declared worthy of a revisit by Lee Silver himself.
