The only way to put it back on course was to burn precisely 14 seconds of fuel. It was here that the OMEGA Speedmaster Professional chronograph saved the day. Swigert’s chronograph perfectly timed the burning of the fuel, while Mission Commander Jim Lovell steered the craft to safety.

How did they save Apollo 13?
Change in Mission Design
For subsequent Apollo missions, oxygen tanks were redesigned, thermostats were modified, and stirring fans were removed. Emergency water and batteries were added to the Command Module, and another oxygen tank was added so that one would never go below half full.
How did Apollo 13 get back to Earth safely?
The craft was launched from Kennedy Space Center on April 11, 1970, 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 17.
Why was Omega chosen as Moon Watch?
The reason for this is that Omega introduced the newer caliber 861 movement for their Speedmaster chronographs. This would mean the rigorous tests needed to be performed all over again (which they did in 1978 for the Space Shuttle program).
Who figured out how do you save Apollo 13?
You probably know that Fred Haise, Jim Lovell, and Jack Swigert made it home safely (water landing shown, with two of the astronauts in white). You may not know the chemist behind the rocket engine that saved them, which began its life as an apparatus for measuring chemical reaction rates.
How did Apollo 13 have enough oxygen?
An explosion 56 hours into the mission happened before the command module and lunar module had separated, so the crew were able to use the intact lunar module as a lifeboat with its own power sources, rockets and oxygen supply.
How hot did Apollo 13 get on reentry?
| Mission | Apollo 7 | Apollo 13 |
|---|---|---|
| Average | 70 | 64 |
| High | 79 | 71 |
| Low | 64 | 58 [sic*] |
| Reentry | 65 | 75 |
Which Apollo blew up and killed?
Apollo 1 fire
The Apollo 1 fire that killed three was on Jan. 27, 1967, while the Columbia disaster that killed seven happened on Feb. 1, 2003.
How hot did it get inside Apollo 13 during reentry?
about 34 degrees Fahrenheit
“The spacecraft cabin temperature on a normal mission is controlled by using heat produced by electrical systems, with the excess heat dissipating by radiation into space. With the electrical systems turned off, the temperature approached about 34 degrees Fahrenheit prior to entering the atmosphere.
How did they fix the problem on Apollo 13?
The testing team decided to solve this problem by heating the tank overnight to force the liquid oxygen to burn off. But the surge of power from the high-voltage DC system on the ground caused the automatic shut-off switches on the tank’s heater to fail, and the temperature spiked to more than 1,000 degrees Fahrenheit.
Why did Apollo 13 have duct tape?
With duct tape, the astronauts managed to repair the fender and complete their geology exploration for the day. Understanding the gravity of the situation, NASA engineers on the ground instructed the astronauts to use duct tape on laminated maps to replace where the fender tore off.
Do astronauts carry duct tape?
— For more than 50 years, NASA astronauts have relied on duct tape as a fix-it-all for everything from a lunar rover on the moon to an air leak on board the International Space Station. Up until now, though, they have not had an easy way to dispense the adhesive.
Did Neil Armstrong wear an OMEGA?
NASA issued this Omega Speedmaster chronograph to astronaut Neil Armstrong for use during the Apollo 11 mission of July 1969.
Do astronauts still wear OMEGA watches?
The new Speedmaster Moonwatch Professional, which continues to be flight-qualified by NASA for use on all of its crewed missions, draws its design from the Omega chronograph worn by Apollo 11 astronauts Neil Armstrong, Buzz Aldrin and Michael Collins in 1969.
Does NASA still issue Omega Speedmaster?
The Speedmaster Professional remains one of several watches qualified by NASA for spaceflight and is still the only one so qualified for EVA. The Speedmaster line also includes other models, including analog-digital and automatic mechanical watches.
Who was the hero of Apollo 13?
Glynn Lunney gave the credit to his team of controllers and the other support staff that spontaneously gathered at Mission Control that night. The crew of Apollo 13 landed safely three days later because of the extraordinary efforts by thousands of people around the country.
Are any of the Apollo 13 astronauts still alive?
Other astronauts from the program who are still alive include: Walter Cunningham, 89 (Apollo 7) William Anders, 87 (Apollo 8) Fred Haise Jr., 87 (Apollo 13)
Why did they have to stir the oxygen tanks?
The O2 tanks were stirred in order to get an accurate reading on the gauging systems, as the cryogenic oxygen tends to solidify in the tanks, and stirring allows for a more accurate reading on the quantity of O2 remaining in the tank. But this was not the first time the crew had been ordered to stir the tank.
Why was Apollo 13 blackout so long?
For the Apollo 13 mission, the blackout was much longer than normal because the flight path of the spacecraft was unexpectedly at a much shallower angle than normal.
Why was Apollo 13 a successful failure?
Why is Apollo 13 a successful failure? The Apollo 13 crew was going to die but they survived and return home. Apollo 13 was called a successful failure because it was a mission to the moon, the astronauts overcame challenges, and return home. It’s important to first note that it was a mission to the moon.
How high did the co2 get on Apollo 13?
The carbon dioxide levels recorded by sensors in the Command and Lunar Modules remained well below the limit of 1010.8 N/m2 (7.6 torr) except for the return flight of [132] the Apollo 13 spacecraft.
