Apollo 15 (Falcon)

  1971-063C


Lunar Module 10 (Falcon) was the first of the advanced J-class LMs, flown on the Apollo 15 mission.

On Jul 30 Scott reported `Okay, Houston. The Falcon is on the plain at Hadley'. Scott's first steps on the surface came a few hours later, with the words `Okay, Houston. As I stand out here in the wonders of the unknown at Hadley, I sort of realize there's a fundamental truth to our nature. Man must explore. And this is exploration at its greatest.'
