Um, that doesnt refute what I stated.
I had a flat tire a couple weeks ago. You would probably recommend I use a traditional AM/FM radio instead of satellite radio because it was more reliable. I'd likely mention that has nothing to do with the situation. You'd respond by saying that doesn't refute what you said...
PoS said:If NASA wants a guaranteed no glitch tech to take to the moon, then they ought to start building Saturn Vs all over again. Those rockets have a 100% success rate.
Guaranteed no glitch tech? 100% success rate?
Following on the heels of the two very successful Apollo 4 and 5 missions, Apollo 6 was the second all-up unmanned test of the Saturn 5. The plan called for the first three stages to place the spacecraft still attached to the third stage into low Earth orbit.
...
The second Saturn 5 lifted off from the Kennedy Space Center’s Launch Complex 39A on April 4, 1968; the mission ran into trouble from the start. Two minutes into the flight, the first stage experienced about 30 seconds of vertical oscillations known as “pogo effect”, which caused no serious damage but would have been very uncomfortable for any crew. Then during the second stage burn, two of the five engines shut down prematurely. The remaining three engines burned longer to compensate for the reduced thrust, as did the third stage to propel Apollo 6 into orbit. When it was time for the third stage to restart, it simply wouldn’t. The flight control team led by Flight Director Clifford Charlesworth decided on an alternate mission plan to separate the spacecraft from the third stage and use the SM engine instead to reach the nearly 14,000-mile altitude. But this used so much fuel that the second SM burn could not be carried out, so reentry occurred at less than the planned speed.
