An introduction to the apollo 13 mission of lunar landing in 1970

A module equipped for two men for two days of travel would have to sustain three men for four long days in a scramble around the Moon and back to Earth. This was a change from Apollo 11 and 12, on which the LM made the burn to bring it to the lower orbit.

What happened to apollo 13 lunar module

Meanwhile, the long-since-discarded S IVB third stage crashed onto the Moon—it had followed an independent trajectory—as part of a planned experiment to cause an artificial moonquake to aid scientists in understanding the nature of the lunar interior. They could not afford to power up the guidance platform again and burn up their precious remaining power. For a short time he experienced a light vibration but no other major changes. But Apollo 13 carried an oxygen tank with a troubled history. The plan for the landing on the moon was aborted, the Apollo 13 made a U-turn at the moon, and she barely made it back to the earth using the little oxygen, water and electric power that remained. At about five minutes past , the warning lamp at the console of the commanding center and one of the yellow lamps were lit. The experts at NASA, employees and contractors, engineered a makeshift adapter from materials the astronauts had on hand to allow them to be used, thus lowering the CO2 levels to acceptable limits. The near-disaster of Apollo 13 was a stunning reminder of the perils of human spaceflight and how NASA, through ingenuity and perseverance, managed to overcome the incident and save the mission's three-man crew. Later, they powered down all of the systems in the lunar module except those required for life support, communications, and environmental control.

Incidental Discussion Because of only one unfastened screw, the lunar landing was cancelled and Apollo 13 was returned to the earth.

Then, the third stage engine ired for an extra nine seconds during its orbital insertion burn. Soon afterward the spacecraft started along its return path home. The agency quickly revised procedures for the Apollo 14 mission and the flights that followed.

As the systems came back on, everyone aboard, in Mission Control, and around the world breathed a sigh of relief. Summary of Events The Apollo 13 mission was launched at p.

He is also the U. The astronauts flew in the " Vomit Comet " in simulated microgravity or lunar gravity, including practice in donning and doffing spacesuits.

Apollo 13 crew

Lovell, Jr. The lunar module consumables were intended to sustain two people for a day and a half, not three people for four days. Suddenly, as Lovell was moving through the tunnel on his way back from Aquarius to Odyssey, a loud explosion was heard. Normally this would be a fairly simple procedure. At the First Lunar Science Conference in January , it was revealed that while the seismometer left by Apollo 12 had detected almost daily impacts of objects onto the Moon, none had been as large as that of Apollo 12's LM, Intrepid, which had been deorbited after being jettisoned. All three astronauts quickly gathered in Odyssey to study the instruments in an effort to determine what had happened. The tank had been damaged in testing, but the spacecraft builders were not aware of a problem. An experiment to measure the amount of atmospheric electrical phenomena during the ascent to orbit had been added after Apollo 12 was struck by lightning; it returned data indicating a heightened risk during marginal weather. Mission Control radioed, "Farewell, Aquarius, and we thank you. Grumman called a team of six University of Toronto engineers, led by senior scientist Bernard Etkin , to solve the problem within a day. The technician at the command center knew that the warning lamp for the hydrogen tanks occasionally becomes lit because he had been operating the purging of the remaining gas of the hydrogen tank. Since the launch, the captain of the commanding ship had experienced a number of small problems. World Space Week Coordinator for Antarctica. That representation shows four horses, one for each member of the crew who flew, and the fourth for Mattingly. Dating it would provide information not only about the Moon, but about the Earth's early history.

We've had a main B bus undervolt. Thus, mission planners for Apollo 13 were able to seek a smaller landing target someplace other than the lunar mares, or seas, upon which Apollo 11 and 12 had set down.

When Jack Swigert flipped the switch to stir the cryo tanks, the power fans were turned on within the tank. To make it worse, the filters for the system in Odyssey were of a different design and not interchangeable.

This margin was far too close for comfort.

Apollo 13 summary

Without power in the command module, there were no heaters. However, even at this point of the first major accident in space, nobody on the space ship realized the critical nature of the conditions. So, the descent engines were fired sufficiently to boost their speed up another fps, thus cutting their total flight time to hours. This did not open up the whole Moon to planners—sites still had to be in the equatorial region of the near side —but they could be more flexible and could seek a site of greater scientific interest. At about five minutes past , the warning lamp at the console of the commanding center and one of the yellow lamps were lit. The resulting impact was to be measured by equipment left behind by Apollo Apollo 11 and 12 each had a backup site for landing in case of launch delays; this requirement also was deleted for Apollo Command module CM pilot Fred Haise, who was still down in Aquarius after the television broadcast, and mission commander, Jim Lovell, who was in between, gathering cables up, both heard the sound. In this time, interests of the American dissapered and no TV show. Dating it would provide information not only about the Moon, but about the Earth's early history. As a consequence of this shift, the fastener of the oxygen supply line in the tank was loosened, and a gap was created. Soon afterward the spacecraft started along its return path home. The starting point of the cause was that the one of the technicians forgot to unfasten one screw when the tank was reinstalled. This is meant to symbolize the Apollo flights bringing the light of knowledge to all people.
