Lately I have ben thinking about the Apollo missions. Apollo 13 specifically. Apollo 13 was originally meant as a moon landing. It was launched on April 11, 1970. It never landed on the moon due to an explosion in its oxygen tanks. The command module was basically crippled. Using the lunar module(LM) as a life boat, they used the pull of the moons gravity in a slingshot effect to pull them back to Earth. They met many other challenges. This could not have ben accomplished with out the effort of astronauts, scientists and engineers on the ground and the astronauts in the space capsule. Flight Commander James A. Lovell, Command Module Pilot John L. "Jack" Swigert and Lunar Module Pilot Fred W. Haise safely returned to Earth April 17, 1970.
