Above the CM was the emergency escape system. The complete assembly including the Apollo spacecraft and the Saturn launch vehicle stood feet tall These powerful engines are required to lift the heavy rocket fast enough to escape Earth's gravity. The first stage engines are burned at liftoff and last for about 2. As the missions progressed, and the more stages they crashed, the more data they got back.
The Alseps continued to return data until , when Nasa shut the programme down. On 14 November , four months after landing on the Moon, Nasa planned to do it again. There had been a few rain showers that day, as a cold front moved across central Florida but meteorologists gave the go-ahead for launch and the countdown proceeded smoothly.
At 36 seconds after launch, as the Saturn V passed through the clouds, the electrical systems in the command module failed. As the rocket continued towards orbit, Griffin sought a solution. On one launch, engineeers found that the Saturn V created its own lightning Credit: Nasa. Griffin had never heard of the switch but asked the Capcom, Gerry Carr, to relay the message to the spacecraft.
The switch flicked, the command module came back online. And once the guidance computers were reset, the crew head for the Moon. When engineers later analysed the launch, they discovered the rocket had generated its own lightning, the exhaust creating a circuit between charged particles in the clouds and the ground.

By Richard Hollingham 26th June Thus, the men estimated that in just a tenth of a second, the Saturn V would burn 10 times the amount of fuel Lindbergh used for his entire trip.
Both rockets are intended to get people to the moon, although the SLS may also be used to send people to deep-space destinations like Mars. So, although more than half a century of design separates the two rockets, they have similar mission profiles.
Both rockets have an escape launch system which is used in aborts during launch , a crew module and a service module. Both rockets use several stages to bring astronauts into orbit , including an upper stage that is used to help the astronauts break free of Earth orbit and push them toward the moon; this maneuver is called a "trans-lunar injection. Rocketeering is a notoriously hard business, and it was especially difficult in the s.
Formal development on the Saturn V began in January ; it was then called the C-5 rocket. The rocket's development was led by Wernher von Braun, a German-born engineer who wanted to test each part of the rocket separately. But NASA was planning to land humans on the moon before the end of the decade, so George Mueller — NASA's director of the office of manned space flight — ordered a test of the entire rocket at once.
A second test of the Saturn V, for the Apollo 6 mission, took place in April Just a few months later, in December , another Saturn V rocket took the Apollo 8 crew into space on the first stage of their moon mission. The first moon landing took place on schedule, in July Finished in , the VAB spans , feet 32, meters , stands feet m tall and is feet m wide. This huge building was originally intended to house the Saturn V during final assembly before launch; after that, the rocket would be towed about 4 miles 6.
While the Apollo program stopped in the s, its infrastructure remains useful. While the Saturn V was a complex machine, the rocket had a remarkable safety record. The Saturn V successfully flew 13 times, including 10 times with people on board. While some of these launches had flaws, in almost every case, the Saturn V sent its cargo safely into orbit. However, the Skylab space station was severely damaged during a Saturn V launch — more on that in the next slide.
Perhaps the most famous test of Saturn V's durability came during the launch of Apollo 12 in , when lightning struck the vehicle a few moments after liftoff. Luckily, although the astronauts saw some strange warning lights from inside their spacecraft, there was no major damage, and they safely proceeded to a landing on the moon's Ocean of Storms.
