Apollo 13: What happened on Nasa's dramatic moon mission 50 years ago
The jettisoning occurred a few minutes before 11 a.m. (CST), April 17, , just over an hour prior to splashdown of the CM in the south Pacific Ocean. The apparent explosion of oxygen tank number two in the Apollo 13 Service Module (SM) caused the . Description The Apollo 13 Lunar Module (LM or LEM) was originally supposed to land at the Fra Mauro region of the Moon. The Apollo 13 mission was aborted as a lunar landing mission on 13 April , 2 days after launch, when an oxygen tank on the Command and Service Module (CSM) overheated and exploded.
Click to see full answer. Beside this, where is the Apollo 13 lunar module now? Apollo 10 jettisoned its lunar module Snoopy into solar orbit where it remains today. Apollo 13 used its lunar module Aquarius as a lifeboat on the trip back to Earth leaving it to burn up in the atmosphere during reentry. Also Know, what happened to the Apollo 11 service module? Although the historic Apollo 11 mission's three astronauts made it home safe, what happened to apollo 13 lunar module once-classified anomaly almost killed them.
The problem occurred during Apollo 11 's return to Earth. It caused a discarded space module to nearly crash into the crew's capsule. Location of Apollo Command Modules. Yes, the service module reentered and burned up.
The LEM the only one meant for the moon that ever came back had to be maneuvered so as to reenter over the Marianus trench. The reason is that is carried a container of plutonium to power a science experiment. It was originally on display at the Musee de l'Air, Paris, France. Is the lunar rover still on the moon? What would the mortgage be on a 100 000 home Lunar Roving Vehicle LRV is a battery-powered four-wheeled rover used on the Moon in the last three missions of the American Apollo program 15, 16, and 17 during and These three LRVs remain on the Moon.
Is the lunar module still on the moon? Where is the Apollo 11 Command Module now? How did they sleep in the lunar module? The astronauts were required to sleep with suits on and located on how to enable task manager by administrator floor.
Apollo 12, 14 - Hammocks had been provided but astronauts had to remain in their suits which hampered sleeping. For Apollo 14 the crew landed on a incline and they kept thinking the LM was about to tip over. Is the Apollo 11 lunar module still in orbit? The fate of the LM is not known, but it is assumed that it crashed into the lunar surface sometime within the following 1 to 4 months.
How many times did we land on the moon? There were six crewed U. What date did Apollo 11 return to Earth? July 24, What was in the Apollo service module? It consisted of two parts: the conical command module, a cabin that housed the crew and carried equipment needed for atmospheric reentry and splashdown; and the cylindrical service module which provided propulsion, electrical power and storage for various consumables required during a mission.
Is Apollo 13 still in space? Apollo 13 was supposed to be NASA's third moon-landing mission. Instead, in an instant, the spacecraft pivoted from a moon-bound landing unit to a crippled vessel.
The spaceflight stands today as a demonstration of NASA innovation saving lives on the fly, and vividly illustrates the dangers of working in space as well. How many orbits did Apollo 11 have before landing on Moon? They jettisoned Eagle before they performed the maneuvers that propelled Columbia out of the last of its 30 lunar orbits onto a trajectory back to Earth.
They returned to Earth and splashed down in the Pacific Ocean on July 24 after more than eight days in space. Where is the original Apollo 13 capsule? Apollo 13, the third scheduled manned lunar how to play natural harmonics on guitar, was launched on April 11,from Kennedy Space Center. How much did the Apollo 11 command module weight?

"It almost felt like I was behind the camera, inside the lunar module."
Apr 10, †Ј Apollo What happened on Nasa's dramatic moon mission 50 years ago and the blast could have happened in lunar orbit or on the surface of the Moon. That module . Apollo 13 "Aquarius" Used as a lifeboat, burned up in Earth's atmosphere April 17, it was reunited with its descent stage, modified to appear like the Apollo 11 Lunar Module "Eagle," and transferred to the Smithsonian for display in the National Ai rand Space Museum's Lunar Exploration Vehicles gallery. National Air and Space Museum. Apollo 13 used its lunar module Aquarius as a lifeboat on the trip back to Earth leaving it to burn up in the atmosphere during reentry. Beside above, what happened to the Apollo 11 service module? Although the historic Apollo 11 mission's three astronauts made it home safe, a once-classified anomaly almost killed them. The problem occurred.
Apollo 13 April 11Ч17, 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, , but the lunar landing was aborted after an oxygen tank in the service module SM failed two days into the mission.
The crew instead looped around the Moon, and returned safely to Earth on April Swigert was a late replacement for Ken Mattingly , who was grounded after exposure to rubella. A routine stir of an oxygen tank ignited damaged wire insulation inside it, causing an explosion that vented the contents of both of the SM's oxygen tanks to space. Without oxygen, needed for breathing and for generating electric power, the SM's propulsion and life support systems could not operate.
The CM's systems had to be shut down to conserve its remaining resources for reentry, forcing the crew to transfer to the LM as a lifeboat. With the lunar landing canceled, mission controllers worked to bring the crew home alive. Although the LM was designed to support two men on the lunar surface for two days, Mission Control in Houston improvised new procedures so it could support three men for four days.
The crew experienced great hardship caused by limited power, a chilly and wet cabin and a shortage of potable water. There was a critical need to adapt the CM's cartridges for the carbon dioxide scrubber system to work in the LM; the crew and mission controllers were successful in improvising a solution.
The astronauts' peril briefly renewed public interest in the Apollo program; tens of millions watched the splashdown in the South Pacific Ocean on television. An investigative review board found fault with preflight testing of the oxygen tank and the fact that Teflon was placed inside it. The board recommended changes, including minimizing the use of potentially combustible items inside the tank; this was done for Apollo The story of Apollo 13 has been dramatized several times, most notably in the film Apollo 13 Ч based on the memoir co-authored by Lovell Lost Moon - and an episode of the miniseries From the Earth to the Moon.
In , U. President John F. Kennedy challenged his nation to land an astronaut on the Moon by the end of the decade, with a safe return to Earth. The mission returned to Earth on July 24, , fulfilling Kennedy's challenge. NASA had contracted for fifteen Saturn V rockets to achieve the goal; at the time no one knew how many missions this would require.
After the excitement of Apollo 11, the general public grew apathetic towards the space program and Congress continued to cut NASA's budget; Apollo 20 was canceled. Even before the first U. Kraft Jr. He was vindicated by post-mission analysis, and implemented a rule that during the mission, the flight director's word was absolute  Чto overrule him, NASA would have to fire him on the spot.
Apollo 13 was to be the second H mission , meant to demonstrate precision lunar landings and explore specific sites on the Moon. There was a greater role for science on Apollo 13, especially for geology, something emphasized by the mission's motto, Ex luna, scientia From the Moon, knowledge. Apollo 13's mission commander, Jim Lovell , was 42 years old at the time of the spaceflight, which was his fourth and last. He was a graduate of the United States Naval Academy and had been a naval aviator and test pilot before being selected for the second group of astronauts in ; he flew with Frank Borman in Gemini 7 in and Buzz Aldrin in Gemini 12 the following year before flying in Apollo 8 in , the first spacecraft to orbit the Moon.
He held a B. According to the standard Apollo crew rotation, the prime crew for Apollo 13 would have been the backup crew [note 2] for Apollo 10 with Mercury and Gemini veteran Gordon Cooper in command, Donn F. Deke Slayton , NASA's Director of Flight Crew Operations, never intended to rotate Cooper and Eisele to a prime crew assignment, as both were out of favor Ч Cooper for his lax attitude towards training, and Eisele for incidents aboard Apollo 7 and an extramarital affair.
He assigned them to the backup crew because no other veteran astronauts were available. However, management felt Shepard needed more training time, as he had only recently resumed active status after surgery for an inner ear disorder , and had not flown since Thus Lovell's crew himself, Haise and Ken Mattingly having all backed up Apollo 11 and slated for Apollo 14 , was swapped with Shepard's.
Of the five, only Mattingly was not immune through prior exposure. Normally, if any member of the prime crew had to be grounded, the remaining crew would be replaced as well, and the backup crew substituted, but Duke's illness ruled this out,  so two days before launch, Mattingly was replaced by Swigert.
For Apollo, a third crew of astronauts, known as the support crew, was designated in addition to the prime and backup crews used on projects Mercury and Gemini. Slayton created the support crews because James McDivitt , who would command Apollo 9 , believed that, with preparation going on in facilities across the US, meetings that needed a member of the flight crew would be missed.
Support crew members were to assist as directed by the mission commander. The Apollo 13 mission insignia depicts the Greek god of the Sun, Apollo , with three horses pulling his chariot across the face of the Moon, and the Earth seen in the distance. This is meant to symbolize the Apollo flights bringing the light of knowledge to all people.
The mission motto, Ex luna, scientia From the Moon, knowledge , appears. In choosing it, Lovell adapted the motto of his alma mater, the Naval Academy, Ex scientia, tridens From knowledge, sea power. It did not have to be modified after Swigert replaced Mattingly as it is one of only two Apollo mission insigniaЧthe other being Apollo 11Чnot to include the names of the crew. It was designed by artist Lumen Martin Winter , who based it on a mural he had painted for the St. Regis Hotel in New York City.
The mission's motto was in Lovell's mind when he chose the call sign Aquarius for the lunar module, taken from Aquarius , the bringer of water. The Saturn V rocket used to carry Apollo 13 to the Moon was numbered SA, and was almost identical to those used on Apollo 8 through Extra propellant was carried as a test since future J missions to the Moon would require more propellant for their heavier payloads.
This made the vehicle the heaviest yet flown by NASA and Apollo 13 was visibly slower to clear the launch tower than earlier missions. Also considered part of the spacecraft was the launch escape system which would propel the command module CM to safety in the event of a problem during liftoff, and the SpacecraftЧLM Adapter, numbered as SLA, which housed the lunar module LM during the first hours of the mission.
Thereafter, testing and assembly proceeded, culminating with the rollout of the launch vehicle, with the spacecraft atop it, on December 15, The Apollo 13 prime crew undertook over 1, hours of mission-specific training, more than five hours for every hour of the mission's ten-day planned duration.
The astronauts of Apollo 11 had minimal time for geology training, with only six months between crew assignment and launch; higher priorities took much of their time. Believing an inspirational teacher was needed, Schmitt arranged for Lovell and Haise to meet his old professor, Caltech 's Lee Silver. The two astronauts, and backups Young and Duke, went on a field trip with Silver at their own time and expense. At the end of their week together, Lovell made Silver their geology mentor, who would be extensively involved in the geology planning for Apollo Concerned about how close Apollo 11's LM, Eagle , had come to running out of propellant during its lunar descent, mission planners decided that beginning with Apollo 13, the CSM would bring the LM to the low orbit from which the landing attempt would commence.
This was a change from Apollo 11 and 12, on which the LM made the burn to bring it to the lower orbit. The change was part of an effort to increase the amount of hover time available to the astronauts as the missions headed into rougher terrain. The plan was to devote the first of the two four-hour lunar surface extravehicular activities EVAs to setting up the Apollo Lunar Surface Experiments Package ALSEP group of scientific instruments; during the second, Lovell and Haise would investigate Cone crater , near the planned landing site.
They flew in the " Vomit Comet " in simulated microgravity or lunar gravity, including practice in donning and doffing spacesuits. Apollo 13's designated landing site was near Fra Mauro crater ; the Fra Mauro formation was believed to contain much material spattered by the impact that had filled the Imbrium basin early in the Moon's history.
Dating it would provide information not only about the Moon, but about the Earth's early history. Such material was likely to be available at Cone crater , a site where an impact was believed to have drilled deep into the lunar regolith.
Apollo 11 had left a seismometer on the Moon, but the solar-powered unit did not survive its first two-week-long lunar night. Developed by the U. The fuel capsule contained about 3. The cask placed around the capsule for transport to the Moon was built with heat shields of graphite and of beryllium, and with structural parts of titanium and of Inconel materials. Thus, it was built to withstand the heat of reentry into the Earth's atmosphere rather than pollute the air with plutonium in the event of an aborted mission.
A United States flag was also taken, to be erected on the Moon's surface. The structure to fly the flag on the airless Moon was improved from Apollo 12's. For the first time, red stripes were placed on the helmet, arms and legs of the commander's A7L spacesuit.
This was done as after Apollo 11, those reviewing the images taken had trouble distinguishing Armstrong from Aldrin, but the change was approved too late for Apollo Apollo 13's primary mission objectives were to: "Perform selenological inspection, survey, and sampling of materials in a preselected region of the Fra Mauro Formation. Develop man's capability to work in the lunar environment.
Obtain photographs of candidate exploration sites. Some of this photography was to be performed by Swigert as Lovell and Haise walked on the Moon. Apollo 13 had twelve cameras on board, including those for television and moving pictures.
None of these was attempted because of the accident. An anomaly occurred when the second-stage, center inboard engine shut down about two minutes early.
Starting with Apollo 10, the vehicle's guidance system was designed to shut the engine down in response to chamber pressure excursions. The crew settled in for the three-day trip to Fra Mauro. At into the mission, with the TV camera running, the crew performed a burn to place Apollo 13 on a hybrid trajectory. The departure from a free-return trajectory meant that if no further burns were performed, Apollo 13 would miss Earth on its return trajectory, rather than intercept it, as with a free return.
He was found to be entitled to a day extension for being out of the country at the deadline. Entry into the LM to test its systems had been scheduled for ; when the crew awoke on the third day of the mission, they were informed it had been moved up three hours and was later moved up again by another hour. A television broadcast was scheduled for ; Lovell, acting as emcee, showed the audience the interiors of Odyssey and Aquarius.
Approximately six and a half minutes after the TV broadcast Ч approaching Ч Apollo 13 was about , nautical miles , mi; , km from Earth. The pressure sensor in one of the SM's oxygen tanks had earlier appeared to be malfunctioning, so Sy Liebergot the EECOM , in charge of monitoring the CSM's electrical system requested that the stirring fans in the tanks be activated.
Normally this was done once daily; a stir would destratify the contents of the tanks, making the pressure readings more accurate. Ninety-five seconds after Swigert activated those switches,  the astronauts heard a "pretty large bang", accompanied by fluctuations in electrical power and the firing of the attitude control thrusters. Swigert reported 26 seconds later, "Okay, Houston, we've had a problem here," echoed at by Lovell, "Houston, we've had a problem.
We've had a Main B Bus undervolt. Lovell's initial thought on hearing the noise was that Haise had activated the LM's cabin-repressurization valve, which also produced a bang Haise enjoyed doing so to startle his crewmates but Lovell could see that Haise had no idea what had happened.
Swigert initially thought that a meteoroid might have struck the LM, but he and Lovell quickly realized there was no leak. Almost everything in the CSM required power. Although the bus momentarily returned to normal status, soon both buses A and B were short on voltage. Haise checked the status of the fuel cells, and found that two of them were dead.
