(PhysOrg.com) -- This image, taken on March 6, 1969, shows the Apollo 9 Command and Service Modules docked with the Lunar Module.
Apollo 9 astronaut Dave Scott stands in the open hatch of the Command Module, nicknamed "Gumdrop," docked to the Lunar Module "Spider" in Earth orbit.
His crewmate Rusty Schweickart, lunar module pilot, took this photograph from the porch of the lunar module. Inside the lunar module was Apollo 9 commander Jim McDivitt.
The crew tested the orbital rendezvous and docking procedures that made the lunar landings possible.
