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.

Did man made attempts to get to the moon before Neil Armstrong?
Not really. Apollo 11 was the first actual landing attempt. Although Russia would have preferred to have beaten the US to the moon, they were never able to even lift a human beyond low Earth orbit. The US did send two manned mission into orbit around the moon before Apollo 11, but they were never scheduled for landing. A11 was the first true landing attempt by any space agency.
US astronaut James A. Lovell, Jr. is 89 years old (birthdate: March 25, 1928).
What rocket on Apollo 13 stopped working midway?
Approximately 2 days into the mission, Apollo 13's Lunar Service Module (engine and systems to service the Lunar Command Module an take it and the Lunar Excursion Module to the Moon) suffered a catastrophic Oxygen tank explosion in O2 tank number 2 (as a result of a inexpensive part malfunction) which ultimately led to the loss of all onboard oxygen and electrical power provided by it.
With no other options, the astronauts used the LEM to survive the next few days back to Earth. They were able to take a photo of the LSM just after detaching it from the Command Module and prior to re-entry and splashdown. The picture shows one side of the craft seriously damaged from accident.
When did Neil Armstrong become an astronaut?
Neil Armstrong's first flight was on Gemini 8 in 1966 and he was assigned to be the command pilot. This was when he became the first US citizens to fly in space. Joseph Albert Walker was the first US citizen to take flight in space several years earlier than Armstrong.
During the Apollo 13 flight how fast were they going to get back through the atmosphere?
In general, Apollo capsules re-entered the atmosphere at speeds of 25 000 mph or 40 000km/h.
Apollo 13 reentered the atmosphere at 36 210.6 feet per second.
Why did Fred and Mary haise divorce?
Fred Haise was the lunar module pilot on Apollo 13 when there was an explosion on it in 1970. Mary was his wife. They got divorced because of all the press pressure that was put on them after Fred arrived back to Earth safely.
Did Fred Haise get his job for Apollo 13 because he know Jim Lovell?
Every astronaut knew all the other astronauts. The astronauts worked together on many projects, often travelling together. So yes, Lovell knew Haise, but he also knew every other astronaut.
The Mercury astronauts received their flight assignments from Robert Gilruth, the head of NASA's manned flight program in the early 60's. It was Gilruth who decided that Alan Shepard be the first American in space and that John Glenn be the first American to orbit the earth. Astronaut Deke Slayton was chosen to fly the 4th Mercury mission (the mission after Glenn), but was grounded in September 1962 before he was able to fly, and his place was taken by Scott Carpenter aboard Aurora 7. Slayton was the only member of the Mercury Seven who did not fly in the Mercury program. Slayton eventually cleared up his irregular heart beat enough to be assigned to the last Apollo mission. His ASTP flight was the first joint mission between the United States and the Soviet Union.
After Slayton was grounded by NASA, he was also grounded by the Air Force. With a new group of astronauts coming into NASA, the administrators felt that they needed someone in charge of the Astronaut Office. His fellow Mercury astronauts insisted that Slayton be given the job and NASA agreed. As the "chief astronaut" Slayton not only selected which pilots became astronauts, he also made crew assignments for space flights. His selections were sent to his superiors in Washington DC for approval. The only time his selection was overruled was when he assigned Joe Engle as the Apollo 17 Lunar Module Pilot (LMP). Since it would be the last lunar landing flight, scientists insisted that geologist, Harrison Schmitt, be assigned as LMP. NASA brass agreed and Schmitt replaced Engle as LMP.
Slayton made all the crew assignments based on availability and need. The first person usually assigned to a flight crew was the commander. While the commander did not chose who flew with him, he did have veto power over Slayton's choices. A commander could ask for a particular astronaut to be assigned to his crew, but there were no guarantees he would get his first choice. One such incident involved Pete Conrad, the Commander of Apollo 12. Slayton assigned Richard Gordon and Clifton C. Williams to Conrad's crew. Conrad initially asked Slayton for Alan Bean instead of Williams. Bean was a student of Conrad's when Conrad was flight instructor at the Naval Flight Test Facility in Patuxent River, Maryland. The 2 men had been best friends for over 10 years, but Slayton stuck with Williams. Conrad finally got his way when Williams was killed in a plane crash on October 5, 1967.
For the most part, the logic behind the crew selection process was kept secret. The only leaks we have are those provided by the crewmembers themselves. It's completely possible that Lovell could have asked for Haise, but if he did, he didn't reveal it in his book. The more likely reason Haise was selected was because he was the best available LMP.
Why don't people like to become astronaut?
It is incredibly competitive, can be dangerous, and takes a lot of hard work. Also some people aren't interested in becoming astronauts.
How does a rocket change its speed in space with no air?
Some people (who have not studied physics) believe that rockets work because the rocket exhaust pushes against the air, and therefore in the vacuum of space where there is no air, rockets won't work - but that is not the case. Rocket exhaust doesn't need to have air to push against. The expanding gases in the rocket's exhaust nozzle push against the rocket. The gas has its own mass and its own inertia, and the change in momentum of the exhaust gas causes an opposite change in momentum of the rocket. This can be difficult to grasp because we think of gas as being virtually weightless, but a large rocket can emit literally tons of exhaust. The fact that it is in the form of a gas doesn't change the result; mass is mass, whether solid, liquid, or gas.
This is WRONG, rocket DOES work in space.
From NASA
"A rocket is a type of engine that pushes itself forward or upward by producing thrust. Unlike a jet engine, which draws in outside air, a rocket engine uses only the substances carried within it. As a result, a rocket can operate in outer space, where there is almost no air."
How it accelerate
"Rocket engines generate thrust by putting a gas under pressure. The pressure forces the gas out the end of the rocket. The gas escaping the rocket is called exhaust. As it escapes, the exhaust produces thrust according to the laws of motion developed by the English scientist Isaac Newton. Newton's third law of motion states that for every action, there is an equal and opposite reaction. Thus, as the rocket pushes the exhaust backward, the exhaust pushes the rocket forward.
The amount of thrust produced by a rocket depends on the momentum of the exhaust -- that is, its total amount of motion. The exhaust's momentum equals its mass (amount of matter) multiplied by the speed at which it exits the rocket. The more momentum the exhaust has, the more thrust the rocket produces. Engineers can therefore increase a rocket's thrust by increasing the mass of exhaust it produces. Alternately, they can increase the thrust by increasing the speed at which the exhaust leaves the rocket."

Where there any photographs of maps made as a result of Apollo 13?
There are no maps made as a result of Apollo 13. The mission objectives of Apollo 13 were never completed, and the crew almost died.
Check your U joints, clunking is always a good sign that they are going bad. try this, hold the brake and cycle the transmission into reverse and listen for the clunk, still holding the brake cycle it into drive. If the u joints are bad you will hear it each time the transmission engages.
In the movie Apollo 13 what former astronaut has a cameo as the captain of the USIwo Jima?
Jim Lovell
In the movie Apollo 13 what country did America race to get to the moon?
The U.S. and the Soviet Union (USSR) were the two nations racing to put a man on the surface of the moon.
What is the differences between administrator accounts and guest accounts?
Guest account is the one where you can set a settings that you need..... For ex. You don't like any1 uninstalling your programs, so in such cases you can use guest account.... In order to activate guest account you have to have a administrator account & it has to be set with a password........ Administration account is normal to control your settings.............
What was Jim Swigert doing when the explosion occured?
Jim Swigert was the command module and he was in the command module, but both Jim Lovell and Fred Haise had gone to the lunar module, just before separating.
In an essay about the Apollo 13 mission where should this sentence appear?
You need to do the essay. We don't do homework for students.
What did the astronauts of Apollo 13 do to survive on the space shuttle?
The Apollo 13 astronauts were not on the space shuttle.
How did the Apollo 13 get back to earth?
The Apollo 13 crew used the Lunar Module as a lifeboat after an oxygen tank exploded, damaging the Service Module. They made critical repairs and used the gravitational pull of the Moon to slingshot back towards Earth, re-entering the atmosphere and splashing down safely in the Pacific Ocean.
