Here the damage to the service module can be seen
Apollo 13 continued on to the moon, circled it, and headed back to Earth. Over the next four days the astronauts faced problems with air supply, energy, and navigation. At times having to repeatedly make "dramatic and untested maneuvers." However, on April 17th 1970, the Apollo 13 astronauts successfully brought their damaged ship home.
Hats off to our space program for getting these men home safely.
