Apollo 9 (March 3–13, 1969) was the third crewed mission in the
United States Apollo program. Launched by a Saturn V rocket and flown
in Low Earth Orbit, the mission flight-qualified the Lunar Module,
showing that its crew could fly it independently, then rendezvous and
dock, as would be required for Apollo 11, the first crewed lunar
landing. Commander James McDivitt, Command Module Pilot David Scott, and
Lunar Module Pilot Rusty Schweickart tested systems and procedures
critical to landing on the Moon. A spacewalk tested the extravehicular
life support backpack. McDivitt and Schweickart, entering the lunar
module through the docking tunnel, became the first humans to pass
between spacecraft without going outside them, two months after Soviet
cosmonauts spacewalked to transfer between Soyuz 4 and Soyuz 5.
Apollo 9, a complete success, was followed by Apollo 10, the dress
rehearsal for Apollo 11.
