The Apollo Photo Archive series comprises the most comprehensive pictorial record of America’s moon-landing program ever published.

This fourth volume covers Apollo 9, a risky but critical step in the space race with the Soviet Union. Commander Jim McDivitt and command module pilot Dave Scott, both Gemini veterans and Air Force pilots, were joined by civilian rookie Rusty Schweickart as lunar module pilot. While orbiting Earth for 10 days, they achieved the first rendezvous and docking with the lunar module. Schweickart took the first Apollo spacewalk, proving the viability of the spacesuit and backpack for the lunar surface.

The 12-volume Apollo Photo Archive features images of spacecraft and rocket assembly; crew background and training; the countdown, launch, mission, and splashdown; and subsequent crew appearances and activities. This volume, Apollo 9 in Photos, includes more than 800 images, of which many pre- and postflight photos have never been published.
