NOW! Apollo-8 info: The first voyage to the moon for a lunar orbit mission.This is the first time the men left the environment of the earth to go to another planet and return to earth. For the first time that a crew is launched into space with the most powerful in space history, Saturn 5. The mission of Apollo 8 was the third launch of the giant that had been problems in the last takeoff. It was a very risky step at that time. Absolutely historic moment for all humanity. Dan Beaumont report. INFO Wikipedia clip: FIRST STAGE OF SATURN 5,The first stage burned for about 2 minutes and 41 seconds, lifting the to an altitude of 42 miles (68 km) and a speed of 6,164 miles per hour (2,756 m/s) and burning 4,700,000 pounds (2,100,000 kg) of propellant.[22]
At 8.9 seconds before launch, the first stage ignition sequence started. The center engine ignited first, followed by opposing outboard pairs at 300-millisecond intervals to reduce the structural loads on the . When thrust had been confirmed by the onboard computers, the 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. And it should be noted that this was considered by the Apollo astronauts as one of the most tense moments in riding the Saturn V, for if the rocket did fail to liftoff after release they would have the lowest chances of surviving a failed launch, given the great amount of hydrogen propellant in the rocket and the launch pad, that if a fully fueled Saturn V exploded on the pad, it would've had the force of a low-yield nuclear bomb, and it would be near impossible to clear the blast using the Launch Escape System.[citation needed]
It took about 12 seconds for the rocket to clear the tower. During this time, it yawed 1.25 degrees away from the tower to ensure adequate clearance despite adverse winds. (This yaw, although small, can be seen in launch photos taken from the east or west.) At an altitude of 430 feet (130 m) the rocket rolled to the correct flight azimuth and then gradually pitched down until 38 seconds after second stage ignition. This pitch program was set according to the prevailing winds during the launch month. The four outboard engines also tilted toward the outside so that in the event of a premature outboard engine shutdown the remaining engines would thrust through the rocket's center of gravity. The Saturn V reached 400 feet per second (120 m/s) at over 1 mile (1,600 m) in altitude. Much of the early portion of the flight was spent gaining altitude, with the required velocity coming later. The Saturn V broke the sound barrier at just over 1 minute at an altitude of between 3 and 4 nautical miles. At this point, shock collars, or condensation clouds, could be seen forming around the bottom of the command module and around the top of the second stage. INFO: WIKIPEDIA.
