From the fifth episode of the great miniseries "From the Earth to the Moon". Ending of this episode is just amazing, great music and great storytelling.

If we had half the determination of the Apollo era, we'd have made manned landings on every ball of rock in this solar system by now.

Agreed, this was the greatest mini-series ever. Sometimes it seems like, as a country, we have lost the determination of the Apollo era.

@monokhem - The Ares V first stage would likely vibrate at unsuitable levels for a human, but it's tolerated because it's not meant to carry humans anyway. The Ares V upper stage shouldn't vibrate more, theoretically, than the Saturn V S-IVB. Given it uses a similar engine and avionics.

You can read about the thrust oscillation results for Ares I-X here:

@monokhem - According to NASA the Ares I-X flight shook less than a Shuttle flight. The Shuttle doesn't vibrate too much for cargo (we put cargo on it all the time). Not to mention that if a vehicle doesn't vibrate too much for humans it certainly wouldn't be too much for cargo. Cargo can handle a lot more vibration than a human can. Hence why unmanned rockets are allowed to vibrate at levels that would be too dangerous for humans (like the unmanned Titan and Delta rockets).

@monokhem - Key word: "were". That's an exaggeration as well: Years ago they were worried it would rattle so much that it would be unsuitable for humans, not that it would shake itself apart or fly off course. The Ares I-X test put those fears to rest.

"It was still to much of a problem"

According to whom? According to whom did the Ares I-X vibrate so much that it was unsuitable for humans or "too much of a problem"? NASA hasn't said that.

[monokhem]

@A86 They were worried it was going to rattle so much it would fly off course and maybe kill people who knows where. It rattled less than that. It was still to much of a problem, and extrapolated for the full sized rocket the vibrations would have wrecked the cargo, Human bodies included.

The info you are going on is incomplete.

[A86]

@monokhem - You do know the worries about vibration came out a couple of years before the Ares was actually tested? When the Ares I-X actually flew the rocket vibrated about 9 times less than the computer predictions predicted it would. The Ares I-X vibrated a little less than a normal Shuttle flight. The vibration-absorbing springs they created for the rocket turned out to be not necessary.

The info you're going on is very old.

[monokhem]

@A86 because the Ares 1-X was tiny. When they found out how much it vibrated and extrapolated that for the rocket that people would actually ride they found out that nothing worth while could ride on it. This stuff isn't secret. You can go learn about it.

[monokhem]

@A86 Constilation was more expensive than the shuttle program by a wide margin. Ask NASA why they had to burn the ISS to fund Constipation if you are upset by that reality.

[monokhem]

@A86 Apollo wasn't designed over ten years.

[monokhem]

@A86 The LEM was designed independently from the Saturn 5.

[A86]

@monokhem - That's why Obama's backpeddling on his plans. Declaring you're going to an asteroid and then having Congress design a rocket (instead of engineers, the SLS is LITERALLY designed by Congressmen, like Ben Nelson) with no function in the meantime and then not funding it isn't a good plan.

"Rocket and lander being developed together = inferior"

A similar thing happened with the Saturn V and the LM before Apollo's budget increased. Do you have an argument besides wordplay with names?
