The nation's Moon landing program suffered a shocking setback on Jan. 27, 1967, with the deaths of Apollo 1 astronauts Virgil I. “Gus” Grissom, Edward H.
On Jan. 27, 1967, a fire swept through the Apollo 1 Command Module during a launch rehearsal test, tragically killing the three astronauts trapped inside. Astronauts Gus Grissom (left), Ed White (middle), and Roger Chaffee (right), died on Jan.
It was the world's first known space tragedy. Veteran space pilots Virgil I. (Gus) Grissom, 40, and Edward H. White, 36, and rookie Roger Chaffee, 31, died in flames while lying on their backs in their moonship in a routine ground test for their Feb.
Burns suffered by the crew were not believed to be major factors, and it was concluded that most of them had occurred postmortem. Asphyxiation occurred after the fire melted the astronauts' suits and oxygen tubes, exposing them to the lethal atmosphere of the cabin.
Apollo 17, U.S. crewed spaceflight to the Moon, launched on December 7, 1972, and successfully concluded on December 19, 1972. It was the final flight of the Apollo program, and Apollo 17 astronauts Eugene Cernan and Harrison Schmitt were the last humans to walk on the Moon.
Apollo 13 (April 11–17, 1970) was the seventh crewed mission in the Apollo space program and the third meant to land on the Moon. The craft was launched from Kennedy Space Center on April 11, 1970, but the lunar landing was aborted after an oxygen tank in the service module (SM) failed two days into the mission.
The Apollo 13 malfunction was caused by an explosion and rupture of oxygen tank no. 2 in the service module. The explosion ruptured a line or damaged a valve in the no. 1 oxygen tank, causing it to lose oxygen rapidly.
Apollo 7 splashed down without incident at 11:11:48 UTC on October 22, 1968, 200 nautical miles (230 mi; 370 km) SSW of Bermuda and 7 nautical miles (8 mi; 13 km) north of the recovery ship USS Essex. The mission's duration was 10 days, 20 hours, 9 minutes and 3 seconds.
After a flight of 195 hours, 18 minutes, 35 seconds - about 36 minutes longer than planned - Apollo 11 splashed down in the Pacific Ocean, 13 miles from the recovery ship USS Hornet. Because of bad weather in the target area, the landing point was changed by about 250 miles.
Apollo 13 was NASA's third moon-landing mission, but the astronauts never made it to the lunar surface. During the mission's dramatic series of events, an oxygen tank explosion almost 56 hours into the flight forced the crew to abandon all thoughts of reaching the moon.
Apollo 12 was launched on November 14, 1969. Despite being struck by lightning twice during the first minute of flight, it went on to perform the second successful human landing on the Moon.
Altogether, Apollo 14 spent 2.8 days in lunar orbit, circling the Moon 34 times. The crew returned safely to Earth on February 9, 1971, landing in the Pacific Ocean near Samoa after a flight of 9 days and 2 minutes.
Apollo 1 – 1967
A flash fire broke out in the command module of Apollo 204 during a simulated launch at Cape Canaveral Air Force Station in Florida, killing astronauts Virgil “Gus” Grissom, Edward White and Roger Chaffee of asphyxiation.
The command module of Apollo 13 entered Earth's atmosphere and splashed down on target on April 17 at 1:07 PM Eastern Standard Time. The mission has been referred to as a successful failure, in that all the crew members survived a catastrophic accident.
It was concluded that the most likely cause was a spark from a short circuit in a bundle of wires that ran to the left and just in front of Grissom's seat. The large amount of flammable material in the cabin in the oxygen environment allowed the fire to start and spread quickly.
As part of the Apollo 12 mission, the camera from the Surveyor 3 probe was brought back from the Moon to Earth. On analyzing the camera it was found that the common bacterium Streptococcus mitis was alive on the camera.
The successful Apollo 9 mission, the most complex crewed space mission flown to that time, brought the Moon landing one step closer. The next step tested the LM in lunar orbit – while Apollo 9 was in orbit, NASA rolled out the Saturn V rocket for that mission, Apollo 10, planned to fly in May.
None of the Apollo 7 crew flew to space again. Even before the flight, Schirra announced his resignation from NASA, while Cunningham and Eisel fell out of favour with flight director Christopher Kraft, who declared that they would never fly again.
Apollo 10 was on the back side of the moon when it was injected into a trans-Earth trajectory. After a midcourse correction, and command and service module separation, Apollo 10 re-entered Earth's atmosphere May 26. The module splashed down 165 degrees west, and 5 degrees, 8 minutes south in the Pacific Ocean.
With the world anxiously watching, Apollo 13, a U.S. lunar spacecraft that suffered a severe malfunction on its journey to the moon, safely returns to Earth on April 17, 1970.
On Flight Day 10, March 13, 1969, the Apollo 9 capsule re-entered Earth's atmosphere and splashed down in the Atlantic Ocean, within three miles and in full view of the recovery ship, the USS Guadalcanal, about 341 miles north of Puerto Rico. The lunar module descent stage decayed March 22.
Apollo 6 splashed down in the Pacific Ocean after a troubled flight of 9 hours and 57 minutes and was recovered aboard the aircraft carrier USS Okinawa. The spacecraft is on display at the Fernbank Science Center in Atlanta, Georgia.
The TLI placed Apollo on a "free-return trajectory" - often illustrated as a figure of eight shape. This course would have harnessed the power of the Moon's gravity to propel the spacecraft back to Earth without the need for more rocket fuel.
Apollo 8 splashed down in the Pacific Ocean at 10:51 a.m. EST Dec. 27. The splashdown was about 5,100 yards from the recovery ship USS Yorktown, 147 hours after launch and precisely on time.
