In the meantime, however, the lunar module would be their home. NASA must devise a strategy to return Apollo 13 to Earth safely after the spacecraft undergoes massive internal damage putting the lives of the three astronauts on board in jeopardy. Apollo 13 was planned as a Type H mission, a precision piloted lunar landing demonstration and systematic lunar exploration. All three astronauts quickly gathered in Odyssey to study the instruments in an effort to determine what had happened. However, a shift back to a free-return trajectory was within the capability of both the service module propulsion system and the lunar module descent stage propulsion system. Apollo 13 was launched on April 11, 1970, for what was planned to be the third human landing on the Moon. Radio contact with Apollo 13 was lost during the evening of April 14 as the craft swung behind the Moon, passing at an altitude of 264 km (164 miles) at the closest approach. Comme les deux précédentes missions elle aurait dû permettre à deux astronautes … The crew included Commander Jim Lovell, Command Module Pilot Jack Swigert, and Lunar Module Pilot Fred Haise. Apollo 13, U.S. spaceflight, launched on April 11, 1970, that suffered an oxygen tank explosion en route to the Moon, threatening the lives of three astronauts —commander Jim Lovell, lunar module pilot Fred Haise, and command module pilot Jack Swigert. The crew was rescued resulting in a "successful failure." Il est lancé par le président John F. Kennedy le 25 mai 1961, essentiellement pour reconquérir le prestige américain mis à mal par les succès de l'astronautique soviétique, à une époque où la guerre froide entre les deux … Apollo 13 launching from Kennedy Space Center, Cape Canaveral, Florida, April 11, 1970. It consists entirely of historical material, all timed to Ground Elapsed Time--the master mission clock. Corrections? The two spacecraft both used lithium hydroxide canisters to remove carbon dioxide from the atmosphere, but the canisters had different shapes on the two spacecraft. With Tom Hanks, Bill Paxton, Kevin Bacon, Gary Sinise. Apollo 13 est annulée suite à une explosion dans le module de service. The command module was named Odyssey, and the lunar module was named Aquarius. Plans were made for transferring out of the hybrid trajectory and onto the free-return trajectory, a maneuver that was executed in the early morning hours of April 14. It is about nine hours since the Apollo 13 crew awoke on their third day in space. Apollo 13 was launched on April 11, 1970, for what was planned to be the third human landing on the Moon. Test your knowledge of those who had the right stuff to travel into space. The mission's spent upper stage successfully impacted the moon. As a safety measure, later Apollo spacecraft were modified to include a third oxygen tank that was isolated from the first two tanks and also included additional emergency battery power. LA TÊTE DANS LES ÉTOILES - Le 17 avril 1970, la mission Apollo 13 décolle. The lunar landing was cancelled and the crew used the lunar module as a life boat to sustain them for the return trip back to Earth. The spacecraft assigned to … Therefore, engineers on the ground devised a makeshift adapter scheme, radioing to Apollo 13 instructions on how to attach the cartridges from the command module to the lunar module hoses. The transposition maneuver (removing the lunar module, code-named Aquarius, from the S IVB adapter) was carried out efficiently, and soon Apollo 13 was coasting toward the Moon on a path so accurate that the first planned course adjustment was canceled. The mission has progressed much like any other Apollo voyage, with its fair share of minor bugs to test the crew and the flight controllers in Mission Control, all of which are dealt with competently. Omissions? 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 1962; he flew with Frank Borman in Gemini 7 in 1965 and Buzz Aldrin in Gemini 12 the following year before flying in Apollo 8in 1968, the first spacecraft to orbit the Moon. The Seventh Mission: The Third Lunar Landing Attempt. Interior of the Apollo 13 lunar module (LM). Only the command module could pass through Earth’s atmosphere; the lunar module would have to be discarded, along with the service module, before the outer atmosphere was reached. Il s'agissait de la treizième mission d'exploration spatiale lunaire programmée, dont le décollage était prévu pour la treizième minute après la treizième heure. Still three days away from Earth, the astronauts moved into the lunar module Aquarius, which they powered up before shutting down the command module Odyssey to conserve the latter’s emergency battery power for the atmospheric reentry maneuver at the end of the mission. The anxiety for the safety of the astronauts was felt in every corner of the globe, and millions of persons remained glued to television and radio sets as the perilous journey unfolded. This meant that should no further propulsive maneuver be made during the flight, the craft would not swing around the Moon and return directly to Earth on a “free-return” trajectory but instead would miss Earth by 4,750 km (2,950 miles). Copy link. Lovell: I believe we’ve had a problem here. Apollo 13, U.S. spaceflight, launched on April 11, 1970, that suffered an oxygen tank explosion en route to the Moon, threatening the lives of three astronauts—commander Jim Lovell, lunar module pilot Fred Haise, and command module pilot Jack Swigert. Apollo 13 était une mission qui a testé la NASA et ses astronautes jusqu'au bout. (Since their trajectory had a higher lunar altitude than other Apollo missions, Apollo 13 set the record for farthest flight from Earth of 401,056 km [249,205 miles].) The crew subsisted on 6 ounces of water per person a day. 10 facts about the Apollo Moon landing missions; On 14 April 1970 at 03:08 UT the personnel of Mission Control were about to earn their ‘Tough’ and ‘Competent’ stripes once again. When the astronauts learned from Houston of the stage’s impact, Swigert radioed back, “Well, at least something worked on this flight.…I’m sure glad we didn’t have an LM [Lunar Module] impact too!”, About two hours later the descent stage propulsion system of the lunar module was ignited for 5 seconds at 10 percent throttle, 21 seconds at 40 percent throttle, and almost 4 minutes at full throttle. Des milliers de livres avec la livraison chez vous en 1 jour ou en magasin avec -5% de réduction .

Please select which sections you would like to print: While every effort has been made to follow citation style rules, there may be some discrepancies. Early on the evening of April 13, the astronauts pressurized the lunar module Aquarius, and Lovell and Haise passed from the command module Odyssey through the connecting tunnel while checking all systems for the forthcoming landing. The Mission Control Center photographed on April 13, 1970, during the fourth television transmission from the Apollo 13 mission. The Apollo 13 mission launched April 11, 1970. C'est la fin d'un terrible suspens qui a transformé l'échec d'une mission scientifique en un exploit humain. Apollo 14 reprend l'objectif principal de la mission Apollo 13 : l'exploration de la formation géologique située à l'ouest du grand cratère Fra Mauro. 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. When an oxygen tank aboard the service module exploded, it ended hopes of a lunar landing.. Le film raconte l'histoire d'Apollo 13, la septième mission spatiale habitée américaine vers la Lune du programme Apollo, qui comprend pour équipage l'astronaute James Lovell (le plus expérimenté de la NASA), Fred Haise et Jack Swigert. The crew used the engines on Aquarius to make three trajectory correction maneuvers that were needed to reach the landing zone in the Pacific Ocean. Mission control: This is Houston. April 12, the day after launch, passed without incident. The job was done, and Haise reported, “Our do-it-yourself lithium hydroxide canister change is complete.”. Le 17 avril 1970, il y a tout juste 42 ans, les trois astronautes de la mission Apollo 13 revenaient miraculeusement sur Terre après qu'un des réservoirs d'oxygène de leur vaisseau a explosé, … Because of the low cabin temperature, atmospheric humidity had condensed, covering the cabin interior with drops of liquid water that fell as rain during the reentry. However, the lunar module’s lithium hydroxide cartridges that removed carbon dioxide from the air would last only about 50 hours, and those from the command module were not designed to fit Aquarius. Apollo 13 Flight Journal Mission Transcripts About 2.5 hours after launch, the still-attached S IVB third stage was reignited to provide the final boost toward the Moon. Articles from Britannica Encyclopedias for elementary and high school students. Shopping. Aside from minor modifications based on previous flight experience, SA-508 was essentially identical the rockets used on the earlier lunar landing missions. Troisième mission lunaire après Apollo 11 et 12, Apollo 13 s’installe dans une certaine routine, bien que la NASA tente de mobiliser les esprits en insistant sur la dimension scientifique. Info. CO2 levels were approaching dangerous levels when Mission Control designed a system using plastic bags, cardboard, and duct tape that allowed Aquarius to successfully use lithium hydroxide canisters from Odyssey. However, the astronauts flew to the Moon and returned to Earth without loss of life, thanks in part to the competence of the crew and the ingenuity of support teams on the ground. Share. Il est également prévu de déposer un ensemble d'instruments scientifiques comme pour toutes les missions Apollo. As a result, both oxygen tanks ruptured and vented their contents to space. Les missions lunaires vont se succéder, mais vont être jalonnées de soucis. Le 11 Avril 1970, à 13 h 13, la fusée Saturn-5 décolle de Cap Canaveral emportant à son sommet le module Apollo 13, contenant les trois astronautes Jim Lovell (commandant de mission), Fred Haise et Jack Swigert. Apollo 13's mission was to explore the hilly upland Fra Mauro region of the Moon. Apollo 13, la 3ème mission du programme Apollo qui consiste à envoyer des hommes sur la Lune. Together with the cryogenic hydrogen tanks, they fed the required supplies to the craft’s three fuel cells, which were needed for the generation of electrical power, oxygen for breathing, and drinking water. Still, it was classified as a "successful failure" because of the experience gained in rescuing the crew. third stage had to burn nine seconds longer to put Apollo 13in orbit. APOLLO 13. En vol, des expériences en impesanteur sont mises en œuvre. Le programme Apollo est le programme spatial de la NASA mené durant la période 1961 – 1972, qui a permis aux États-Unis d'envoyer pour la première fois des hommes sur la Lune. A post-mission investigation revealed that the explosion was a result of a change made to the spacecraft design in 1965, when the heaters in the oxygen tanks were changed from 28 volts to 65 volts. On the third day of the mission, when the spacecraft was nearly 200,000 miles from Earth, the routine activation of a fan in one of the service module's oxygen tanks led to a short circuit and an explosion in that tank. De gauche à droite, Fred W. Haise, James A. Lovell et John L. Swigert, les trois membres de la mission Apollo 13.

It was 13 April, 9.05pm local time in Houston (14 April, 03:07 UT), 55 hours and 52 minutes into the mission and Apollo 13 was 322,000km from home. All thoughts of a lunar landing had long since been abandoned. To do this, the service module’s propulsion system provided a 4.6-metre- (15-foot-) per-second velocity change designed to lower the command module’s closest approach to the Moon from 389 km (242 miles) to 109 km (68 miles) and place the craft on a “non-free-return” trajectory. Apollo 13 was to be the third lunar landing attempt, but the mission was aborted after rupture of service module oxygen tank. hero-wars.com/play_free_now. Please refer to the appropriate style manual or other sources if you have any questions.

However, four days prior to launch, it was determined that Mattingly had been exposed to measles and had no immunity. https://www.techno-science.net/glossaire-definition/Apollo-13-page-2.html We’ve had a main B bus undervolt. Apollo 13 was NASA's third moon-landing mission, but the astronauts never made it to the lunar surface. Soon afterward the spacecraft started along its return path home. This was not to be. An entire panel on the SM was blown away by the explosion of an oxygen tank. Lovell: Houston, we’ve had a problem. Pres. On board the spacecraft, oxygen stores remained sufficient, as did cooling water. Just over two days into the mission, Jack Swigert radioed down from the Apollo 13 command module Odyssey, “Okay, Houston, we’ve had a problem here.” Apollo 13 was launched from Cape Kennedy, Florida, by a giant Saturn V launch vehicle and only minutes later was inserted into orbit around Earth. When the astronauts first transferred into and activated Aquarius, Apollo 13 was about 20 hours from the Moon. Updates? Apollo 13 est une mission spatiale au début des années 70 pour aller sur la Lune. About an hour after the accident, mission control announced that “we are now looking toward an alternate mission, swinging around the Moon and using the lunar module power systems because of the situation that has developed here this evening.” The astronauts were to move into Aquarius, which would serve as a lifeboat, while the disabled Apollo 13 swung around the Moon and headed homeward. Tap to unmute. Watch later. Our editors will review what you’ve submitted and determine whether to revise the article. Within eight seconds of the explosion, pressure in one of the service module’s two cryogenic oxygen tanks had dropped to zero. Apollo 12 débute avec la foudre qui frappa la fusée, mais cela n’empêcha pas la réalisation de la mission. Background . Lancée le 11 avril 1970, une fusée Saturne V emporte dans l'Espace l'équipe d'Apollo 13. In order to avoid the possibility of Mattingly becoming sick during the flight, he was replaced by his back up, Jack Swigert. Mission Apollo 13, Philippe Nessmann, Flammarion Jeunesse Pere Castor. https://www.britannica.com/topic/Apollo-13-mission, Lunar and Planetary Institute - Apollo 13 Mission, Smithsonian National Air and Space Museum - Apollo 13, Apollo 13 - Student Encyclopedia (Ages 11 and up). The crew included Commander Jim Lovell and Lunar Module Pilot Fred Haise, who were scheduled to land in the lunar module Aquarius and explore the Fra Mauro region of the Moon. Power was severely rationed, and the temperature inside the cabin dropped below 40 °F (4 °C), causing the crew great difficulty sleeping. Apollo 13 Every Apollo mission had at least one major crisis, so he was relieved Apollo 13’s was out of the way early. So accurate was the hybrid transfer that a scheduled course correction was canceled. Unfortunately, the switches in the tank that exploded were not changed to handle the higher voltage, resulting in unrecognized damage during a ground test two weeks before the launch and ultimately in the short circuit during flight. Apollo 13 was to be the third lunar landing attempt, but the mission was aborted after a rupture of the service module oxygen tank. Rien ne se passe comme prévu et l'équipage (et la Nasa) devra tout tenter pour pouvoir revenir vivant sur Terre. This website replays the Apollo 13 mission as it happened, 50 years ago. The astronauts reduced their consumption of drinking water to six ounces per day and their consumption of electricity by 80 percent.
