The two members of the Apollo 13 crew who planned to land on the Moon's Fra Mauro region in the lunar module undergo a walk-through of the extravehicular activity timeline. Fred W. haise, Jr., Lunar Module Pilot (r.), tries out a motorized core sampler while James A. Lovell, Jr., the Apollo 13 Commander, looks on (l.). NASA

This view of the damaged Apollo 13 Service Module (SM) was photographed from the Lunar Module/Command Module following SM jettisoning. As seen here, an entire SM panel was blown away by the apparent explosion of oxygen tank number two. The damage to the SM caused the Apollo 13 crewmen to use the Lunar Module as a 'lifeboat.' The Lunar Module "Aquarius" was jettisoned just prior to Earth reentry. NASA
Astronaut John L. Swigert, Jr., Apollo 13 Command Module Pilot, holds the 'mailbox,' a jerry-rigged arrangement which the Apollo 13 astronauts built to use the Command Module lithium hydroxide canisters to purge carbon dioxide from the Lunar Module. Lithium hydroxide is used to scrub CO2 from the spacecraft atmosphere. Since there was a limited amount of lithium hydroxide in the Lunar Module, this arrangement was rigged up using the canisters from the Command Module. NASA
This photograph of the Earth was taken from the Apollo 13 spacecraft during its journey home. The most visible land mass includes southwestern United States and northwestern Mexico. The penisula of Baja California is clearly seen. Most of the land area is under heavy cloud cover. NASA
An unidentified airline passenger snapped these bright objects, believed to be the Apollo 13 Service Module and Lunar Module as they entered Earth's atmosphere over the Pacific Ocean on April 18, 1970. NASA
Astronaut John L. Swigert Jr., Apollo 13 command module pilot, is lifted aboard a helicopter in a "Billy Pugh" net while Astronaut James A. Lovell Jr., commander, awaits his turn. Astronaut Fred Haise Jr., lunar module pilot, is already aboard the helicopter. In the life raft with Lovell and in the water are several US Navy Underwater Demolition Team Swimmers who assisted in the recovery operations. NASA
The Apollo 13 spacecraft heads toward a splashdown in the South Pacific Ocean. The Apollo 13 Command Module splashed down in the South Pacific at 12:07:44 p.m. on April 17, 1970. Note the capsule and its parachutes just visible against a gap in the dark clouds. NASA
Three of the four Apollo 13 Flight Directors applaud the successful splashdown of the Command Module 'Odyssey.' The Flight Directors are from left to right: Gerald D. Griffin, Eugene F. Kranz and Glynn S. Lunney. NASA
Crewmen aboard the U.S.S. Iwo Jima, prime recovery ship for the Apollo 13 mission, hoist the Command Module aboard ship. The Apollo 13 crewmen were already aboard the Iwo Jima when this photograph was taken. NASA
Apollo 13 astronauts Fred Haise, John Swigert, and James Lovell are pictured during the press conference after their ill-fated mission, aborted after 56 hours of flight, 205,000 miles from Earth, when an oxygen tank in the service module exploded. NASA
