Apollo 13

Apollo 13 was the name of the fateful NASA moon mission which was intended to be the third space mission to carry humans to the moon's surface. An explosion of one of the oxygen tanks and resulting damage to other systems caused the mission to be aborted before the lunar landing could take place. Questions about Apollo 13 and its crew are asked and answered here.

935 Questions

How much fuel did Apollo 13 need to get to the moon?

Apollo 13 never made it to the moon, suffering a catastrophic failure en route. The Apollo missions in general used 5.625 million pounds of fuel in all three four stages of the Saturn V rocket.

Who was the flight director of the Apollo 13 mission?

The flight director of the Apollo 13 mission was Gene Kranz. He played a crucial role in guiding the mission back to Earth after an oxygen tank explosion threatened the lives of the astronauts. His leadership and decision-making skills were essential in ensuring the safe return of the crew.

What are the three names of the men who went on the Apollo 13 mission?

The three names are- Jim Lovell John (Jack) Swigert Fred Haise

How fast did Apollo 11 travel to get to the moon?

19 000 mph to the moon, not sure how it slowed down though. Not sure how it managed that speed to get back.

Did Apollo 13 go to the moon?

Apollo 13 went around the moon but did not land as planned due to an earlier explosion which ruptured the oxygen tanks. It was safer and used less fuel to continue around the moon than to do an immediate u- turn.

Why was the Apollo 13 mission considered a successful failure?

Apollo 13 was a failure in the sense that the mission did not land on the moon or achieve any of its mission goals. It was successful because it showed how people can work together to bring about a successful outcome to a situation that looked impossible. The feat of bringing home a crew of three in a spacecraft that was largely disabled through the rupture of its oxygen tanks and damaged electrical systems was a worldwide effort by various technical people, and created universal concern for the astronauts wellbeing.

What is the first problem Apollo 13 encountered?

The first major problem occured before the flight; the Command Module (Ken Mattingly) pilot was grounded by flight doctors after being exposed to German Measles; Mattingly was not immune and it was considered too risky for him to fly. Mattingly was replaced by John Swigert. The most serious problem, of course, was the explosion of a fuel cell oxygen tank which made the service module too risky to use for the remainder of the mission.

What data or information did Apollo 13 collect?

During the Apollo 13 mission, various data and information were collected, such as telemetry on spacecraft systems, communication with mission control, navigation readings, biomedical data on the astronauts, and celestial observations. This data was crucial for monitoring the health and status of the spacecraft and its crew, guiding decision-making, and ensuring a safe return to Earth despite the mission's complications.

Where did Apollo 13 land?

The Pacific Ocean.

The Apollo landed in Pacific ocean near the coast of US Territory of American Samoa. (Not sure whether it was Apollo 13 or 11)

Apollo 13 did not land on the moon. Due to major issues mid-flight the astronauts couldn't land.

Why didn't they check the ship before left off on Apollo 13?

The ultimate cause of the Apollo 13 explosion (a thermostat that wasn't designed for the 68volt ground power which, when applied, fused the contacts of the thermostat open, forcing the tank heater to stay on, and increasing the temperature inside the tank to nearly 1,000 degrees, thereby melting the insulation off the wiring of the tank stirring fan circuit, which then sparked when activated) is not something that would have been caught during a ground inspection, which was actually done. Even they had wanted to examine the thermostat, the oxygen tank was not designed to be opened, and the thermostat was inside the tank.

What was Apollo 13's purpose?

Apollo 13 was intended to be the seventh crewed mission in the Apollo program to land on the moon but had to be aborted after an oxygen tank exploded on the spacecraft. The main focus of the mission then became safely returning the crew back to Earth.

What are three problems that occurred on Apollo 13?

  1. Electrical fault on an O2 canister caused an explosion in the oxygen tank which also damaged the second tank. This left the spacecraft virtually crippled, as the oxygen tanks were necessary for the supply of electrical power.
  2. CO2 scrubbers became saturated by change in mission profile. The Lunar Module (LEM) was not designed for 3 astronauts, and the system became overwhelmed. This simple problem would have killed the astronauts , but some makeshift adjustments solved the problem.
  3. The trajectory of the spacecraft was affected because of the venting of oxygen into space, and the actual physical disruption caused by the explosion. Also the necessary abandonment of the moon landing meant that the crew needed to be brought back to earth by a different route, and one that was as short as possible. Because there was the possibility of the main engine having been affected, this need to be done using the LM's engines, something certainly not performed before in space.

How long did it take for Apollo 11 to reach the moon?

Apollo 11 launched June 16, 1969. After doing one and a half orbits around the Earth, the astronauts were off to the moon. The trip took 4 days, 6 hours, and 45 minutes.

What was the name of the American spaceships used in the trips to the moon?

The program was called Apollo, and the missions designated with a number. Apollo 11 was the first to land on the moon. The command and lunar modules were all given different names by their crews.

Why did the oxygen tank blow up on Apollo 13?

Cause of explosion

A short circuit occurred in the electrical system when the oxygen tanks were stirred. This caused oxidation and pressure loss to occur in one tank, and then the other which critically disabled the craft and aborted the mission.

The cause of the shorting was later thought to be from a combination of switch design and pre-launch detanking procedures where a switch welded shut, although this was unknown at the time. Normally this switch would open when the temperature rose and turn the heater off. Prior to this, there was a redesign of the voltage system and all components of the tanks were upgraded to the new voltage except the heater thermostat switches. This incompatibility allowed the temperature to rise during testing and to damage the Teflon-coated wiring.

Later, during the mission when the tank was stirred, the exposed wires shorted and the Teflon caught fire. In the pure oxygen environment, the fire was intense, and the resultant heat caused the tank to rupture and also damage the adjacent tank. One cover on the service module was blown off, which later caused Lovell to exclaim when he saw it as it was jettisoned " There's one whole side of that spacecraft missing!" Because the service module burnt up in the earth's atmosphere, as was normal procedure, the findings were made from an investigation into pre-launch procedures and reconstructions of the likely cause of events. The above conditions were simulated in a hangar, and another explosion occurred.

Why was the apollo 13 mission significant?

The Apollo 13 mission was significant because it demonstrated the ability of NASA to handle a major in-space emergency and safely return the astronauts to Earth despite technical failures. It showcased teamwork, problem-solving, and quick thinking under pressure. Additionally, it led to changes in NASA's procedures and practices to prevent similar incidents in the future.

When did Apollo 13 reach the moon?

Apollo 13 passed around the moon on April 15, 1970 (it did not land due to an explosion in its oxygen tank earlier in the mission).

What was the purpose of Apollo 13?

1. to build on the knowledge and expertise of the previous missions 11, and 12 (in addition to the other non-landing missions) .

2. To explore another region of the moon - the Fra Maura region where the geology and topography was very different from the other landing sites. In order that exploration was successful different regions had to be explored. Imagine an alien judging the earth as hot, dry and lifeless just because he happened, in his sole mission to earth, to land in the Sahara desert.

Well also to make shure the other apollos wern't flukes to test that it all didn't depend on a variable that coudn't stay constenet

How fast was the Apollo 13 rocket going so that it didn't fall back to earth?

The Apollo 13 rocket was traveling at a speed of about 24,500 miles per hour (39,500 km/h) to escape Earth's gravitational pull and reach the Moon. This speed ensured that the spacecraft could maintain its trajectory and continue its journey into space.

What was Apollo's appearance?

Apollo was typically depicted as a handsome and youthful man with long hair and a serene expression. He often carried a bow and arrow, representing his role as the god of archery and the sun. He was also associated with music and poetry.

Where did the first rocket in space go?

The first rocket to reach "space" was a German V-2 (the A4 rocket weapon) launched during World War II. According to test records, the first rocket to reach "space" was likely the fourth test launch on October 3, 1942.

When did Apollo 13 land?

Apollo 13 never landed on the moon because of a catastrophic malfunction. However, it made a successful landing back on Earth on April 17, 1970.

When did Apollo 13 launch?
