 After launching on March 3, 1969, the crewmen performed the first manned flight of a LM, the first docking and extraction of a LM, two spacewalks (EVA), and the second docking of two manned spacecraft—two months after the Soviets performed a spacewalk crew transfer between Soyuz 4 and Soyuz 5. The mission proved the LM worthy of manned spaceflight. Further tests on the Apollo 10 mission would prepare the LM for its ultimate goal, landing on the Moon. They returned to Earth on March 13, 1969.
