(See It took about 12 seconds for the rocket to clear the tower. The Saturn V was a three-stage rocket. It was 42 m (138 ft) tall and 10 m (33 ft) in diameter, and provided 33,000 kN (7,500,000 lbf) of thrust to get the rocket through the first 61 km (38 mi) of ascent. The S-IVB burned for almost six minutes giving the spacecraft a velocity close to the Earth's escape velocity of 25,053 mph (40,319 km/h). The S-IC (pronounced S-one-C ) was the first stage of the American Saturn V rocket. You will receive a verification email shortly.There was a problem. A fully fueled Saturn V exploding on the pad would have released the energy equivalent of 2 kilotons of TNT (8.4 TJ). The only significant changes to the Saturn V from the Apollo configurations involved some modification to the S-II to act as the terminal stage for inserting the Skylab payload into Earth orbit, and to vent excess propellant after engine cutoff so the spent stage would not rupture in orbit.

When thrust had been confirmed by the onboard computers, the rocket was "soft-released" in two stages: first, the hold-down arms released the rocket, and second, as the rocket began to accelerate upwards, it was slowed by tapered metal pins pulled through dies for half a second.Once the rocket had lifted off, it could not safely settle back down onto the pad if the engines failed.

The Saturn V remains the largest and most powerful U.S. expendable launch vehicle ever built.The Apollo spacecraft, including the Command Module (CM), Service Module (SM) and Lunar Module (LM) sat atop the launch vehicle.

The rocket generated 34.5 million newtons (7.6 million pounds) of thrustat launch, creating more power than 85 Hoover Dams. The Saturn V carried all Apollo lunar missions, which were launched from Launch Complex 39 at the John F. Kennedy Space Center in Florida. If you know your browser is up to date, you should check to ensure that Eight small solid fuel separation motors backed the S-IC from the rest of the vehicle at an altitude of about 42 miles (67 km). All three stages used When loaded, significantly more than 90 percent of the The S-IVB was the only rocket stage of the Saturn V small enough to be transported by The instrument unit was built by IBM and was placed on top of the third stage.

When oxidizer or fuel depletion was sensed in the suction assemblies, the remaining four outboard engines were shut down. We can easily guess that the « S » stands for « stage », so the second stage is named quite logically, « S-II » for « stage 2 » with the use of roman numbers.

Despite some controversy, a Early in the planning process, NASA considered three methods for the Moon mission: At first, NASA dismissed LOR as a riskier option, as a The Saturn V's size and payload capacity dwarfed all other previous rockets successfully flown at that time. It was built by …

The S-II (pronounced "S-two") was the second stage of the Saturn V rocket. This venting also maintained safe pressures as liquid hydrogen boiled off in the fuel tank.

A pogo suppressor was fitted to later Apollo missions to avoid this, though the early engine 5 cutoff remained to reduce Unlike the two-plane separation of the S-IC and S-II, the S-II and S-IVB stages separated with a single step. The "V" designation originates from the five powerful F-1 engines that powered the first stage of the rocket. The first two stages were so massive that the only way to transport them was by barge. The McDonnell Douglas Astronautics Company provided the Saturn V's third stage. Please refresh the page and try again.Space is part of Future US Inc, an international media group and leading digital publisher. © The second stage is then also discarded.Third Stage (S-IVB): The third stage contains one J-2 engine. NY 10036.

The instrument unit now computed in real time the most fuel-efficient trajectory toward its target orbit. Like the first stages of most rockets, most of its mass of more than 2,000 t (4,400,000 lb) at launch was propellant, in this case RP-1 rocket fuel and liquid oxygen (LOX) oxidizer.

Above the CM was the emergency escape system.The complete assembly including the Apollo spacecraft and the Saturn launch vehicle stood 363 feet tall (110.6 meters) and weighed over 6 million pounds (2.7 million kg).The Saturn V launch vehicle itselft consisted of three stages:First Stage (S-IC): The first stage includes the five F-1 engines producing nearly 7.7 million pounds of thrust. About two and a half hours later, the third stage engine is restarted to send the Apollo spacecraft out of Earth orbit and toward the moon.After the astronauts in Apollo dock with the lunar landing module and pull away from the now-useless third stage, this last remaining part of the Saturn V coasts away into deep space or is commanded to fly to a crash landing on the moon.Get breaking space news and the latest updates on rocket launches, skywatching events and more!Thank you for signing up to Space. The reason of this strange naming is historical. The first stage produced 33.4x 10 6 N (7.5 million pounds) of thrust with five engines. The third stage carries 66,700 gallons (252,750 liters) of liquid hydrogen fuel and 19,359 gallons (73,280 liters) of liquid oxygen. The On Apollo 11, TLI came at 2 hours and 44 minutes after launch. The astronauts considered this one of the tensest moments in riding the Saturn V, for if the rocket did fail to lift off after release they had a low chance of survival given the large amounts of propellant. This engine burns for 2.75 minutes boosting the spacecraft to orbital velocity of about 17,500 mph. From Stages to Saturn p. 212. To ensure sufficient velocity was reached, the remaining four engines were kept active for longer than planned.
