Mission Highlights
Apollo 9 was the first space test of the complete Apollo spacecraft, including the third critical piece of Apollo hardware besides the Command/Service Module (CSM) and the Saturn V launch vehicle—the Lunar Module (LM). It was also the first space docking of two vehicles with an internal crew transfer between them. For ten days, the astronauts put both Apollo spacecraft through their paces in Earth orbit, including an undocking and redocking of the lunar lander with the command vehicle, just as the landing mission crew would perform in lunar orbit. Apollo 9 gave proof that the Apollo spacecraft were up to this critical task, on which the lives of lunar landing crews would depend.
For this and all subsequent Apollo flights, the crews were allowed to name their own spacecraft (the last spacecraft to have been named was Gemini 3). The gangly LM was named Spider, and the CSM was labeled Gumdrop because of the Command Module's shape, and also the blue wrapping in which the craft arrived at Kennedy Space Center. These names were required as radio call signs when the vehicles flew independently.
Schweickart and Scott performed a spacewalk (EVA)—Schweickart checked out the new Apollo spacesuit, the first to have its own life support system rather than being dependent on an umbilical connection to the spacecraft, while Scott filmed him from the command module hatch. Schweickart was due to carry out a more extensive set of activities to test the suit, and demonstrate that it was possible for astronauts to perform an EVA from the lunar module to the command module in an emergency, but as he had been suffering from space sickness the extra tests were scratched.
McDivitt and Schweickart later test-flew the LM, and practiced separation and docking maneuvers in Earth orbit. They flew the LM up to 111 miles (179 km) from Gumdrop, using the engine on the descent stage to propel them originally, before jettisoning it and using the ascent stage to return. This test flight represented the first flight of a manned spacecraft that was not equipped to reenter the Earth's atmosphere.
The splashdown point was 23 deg 15 min N, 67 deg 56 min W, 180 miles (290 km) east of Bahamas and within sight of the recovery ship USS Guadalcanal. Apollo 9 was the last spacecraft to splash down in the Atlantic Ocean.
The command module was displayed at the Michigan Space and Science Center, Jackson, Michigan until April 2004 when the center closed. In May 2004, it was moved to the San Diego Aerospace Museum (now named the San Diego Air and Space Museum). The LM ascent stage orbit decayed on October 23, 1981, the LM descent stage (1969-018D) orbit decayed March 22, 1969. The S-IVB stage J-2 engine was restarted after Lunar Module extraction and propelled the stage into solar orbit by burning to depletion.
The crew sang the song "Happy Birthday to You" on March 8, 1969.

“We never can tell how our lives may work to the account of the general good, and we are not wise enough to know if we have fulfilled our mission or not.”
