Ares 1-X Ready On Pad, Launch Set For 1200 GMT
DynaSoar writes "NASA's new Ares I-X rocket is undergoing final preparations for its planned launch test Tuesday, October 27. Launch time is scheduled for 8 AM EDT (1200 GMT). As of noon Monday it appeared that there was a 60% chance of showers and/or high altitude clouds interfering. However, the launch has a an eight hour window of opportunity through 2000 GMT, and would require only 10 minutes of clear skies within that time to fly. Of interest to engineering types, both those who favor the new vehicle's design and its critics, will be to see whether the predicted linear 'pogo stick' oscillation will occur, and whether the dampening design built into it prevents damaging and possibly destructive shaking. Extensive coverage is being presented by Space.com; for NASA TV streaming video, schedules and downlink information, visit nasa.gov/ntv." Update 15:37 GMT by timothy: The weather did not cooperate; today's planned launch has been scrubbed.
First launc *Kaboooom*
This is awesome. It shows that the US is still number one, and that all you haters don't know what you are talking about. And btw. Obama didn't start Ares, Bush did.
As long as they are good....
Query: are rockets spaceships and if so are they female like normal ships? They've always seemed a bit to... phallic and gaseous to be female.
It's about bloody time they got this thing started. Of course, being on the pad is just the first step.
Once we've verified the structural integrity of the design, it would be nice to go ahead with astronaut insertion and extended earth orbit. People have been ragging on this design for a while, but I have high hopes that a return to the rocket-centric designs of yesteryear will put us back in the forefront of space exploration.
Tampon.
I'm watching the stream now of them assembling the Ares and I must say the VAB is the most impressive building I've ever seen. I got to tour the inside (way back in the early 90s) and the amount of empty space available, inside a building that can withstand hurricane force winds. It is truly mind-boggling.

they emptied their territory's coffers, just like they (our corepirate nazis) are doing here now.
they'll need every penny & it will not be enough to save them from the creators' newclear powered planet/population rescue initiative/mandate/big flash. as the expression goes; get ready to see the light.
What is going to happen with the Ares V? I heard rumors about it being scrapped. I hope they were wrong?

This 'new' rocket is basically a solid booster from the space shuttle, that needs to be extended with a 5th segment, but it now flies with a 5th dummy segment. On top of that is more dummy weight. This is just a test of an existing and older booster. Now why do you think there is some kind of competition in rocketry that the US can be number one in? Or are you just happy you or your parents paid taxes for this upcoming show?
Or am I a 'hater' because I a a little sceptic about this project of NASA because you cannot understand discourse? Personally, I am much more impressed with SpaceX and Armadillo, who seem to come up with nice projects for much less money. Wasn't there a new SpaceX big rocket on the launchpad soon?
This space is intentionally staring blankly at you
A cylindrical structure is subject to unstable wake flows, where small asymmetries in the flows around the structure lead to alternating vortices behind it. This is commonly termed vortex shedding, and leads to substantial lateral loads which vary fairly quickly and may cause resonance problems in the structure http://en.wikipedia.org/wiki/Vortex_shedding. That's why tall smokestacks nowadays usually have corkscrew fins - to deliberately introduce turbulence, so that the load is less variable and resonant load frequencies have negligible amplitudes.

The vibrations that are commonly called 'pogo' in big rockets are caused by a feedback / resonance of thrust oscillations with inlet pressure of the turbopumps, see this extensive discussion. Pogo is fixed by adding dampers to the propellant lines. Ares I, like every big solid, has combustion instabilities that cause thrust oscillations, but there's no feedback like in a liquid rocket. Only danger is hitting one of the structural resonances and ringing the rocket like a bell (and possibly causing the structure to 'diverge').
Though I have always adored the thought and reality of space travel--this is just a luxury we cannot afford now. There is no pressing problem that would cause this need to travel to the Moon or Mars to occur.
We have so many problems in the United States right now and I really don't see why this is necessary. Since this just recycles Space Shuttle technology, I don't see that this Ares I rocket represents any innovation that would justify the expense.
Though I know all the Aerospace Engineers are going to hate me for killing off their jobs program, there are other scientific needs--such as the need to develop clean energy sources and stop global Climate Change in its tracks--that warrant priority over any dough we spend at NASA.
Example of International Space Station
Currently, for example, the ISS is slated to be decommissioned in a few short years. I ask you, what sort of great innovation has resulted from the ISS? I am hard-pressed to think of any great advances in knowledge that were not already known from by the time the cruddy but long-surviving MIR burned up in the atmosphere.
Again, though I adore seeing these rockets take off and follow every STS-n mission with great interest, it's just a joyride and is not justified in a country like ours that is in danger of becoming a has-been global power.
NASA should halt the Ares-I and, even more painful because it would have been the biggest rocket to date, the Ares V. They are boondoggles that do not solve a pressing problem.
Why is NASA so bent on using the solid-fuel boosters, when the military already has the much cheaper Delta iV Heavy and Atlas V rockets that have been proven?
It's supposed to be completely automatic, but actually you have to press this button.
...I wonder if it could get blown off course :0
I would rather throw a few thousand people off of disability and have the spaceship, then not, if it comes to that.
This is my sig.
As I write, delayed till 9:44 EDT
Just announced cargo ship in the range will need up to 90 min to clear the area.
Personally, I think they should go ahead and launch it. The amount of money wasted in the hundreds of people running amok in Florida is outstanding.
"Can you imagine the lateral stress on the structure if you attempted to build it horizontally and then hoist?
Ask the Russians, that's how they rig the Soyuz rockets. Been doing it pretty successfully for 40 years or so now.
Launch scrub for today due to weather.
char*f="char*f=%c%s%c;main(){printf(f,34,f,34);}";main(){printf(f,34,f,34);}
looks like they have to scrub the launch.
My ism, it's full of beliefs.
Mission officially scrubbed
"If it's stupid and it works....it's not stupid."
Launch is scrubbed for the day. They will try again tomorrow.
The "pogo stick" vibration is due to the frequency of the five segment motors, this test is flying a four segment motor and a mass simulator/instrument package. The vibration will not occur.
I don't know why people like to toss that extra "en" in there. It's like when people spell ligthening for lightning.
Some items to note:
You know I have 10 mod points, but I already posted this thread, so I can't mod you up. But let me say to others with points that you should not be modded down for what you wrote. This is not flamebait.

Look at a map, Yahoo. Brownsville is about at the same latitude as Miami. The increased payload due to latitude would be negligible. And there aren't any safe launch azimuths at all. A direct easterly launch would drop a first stage on Miami. A high inclination launch to the ISS would put the drop zone in St. Louis. Nice try. Cape Canaveral was well chosen site, indeed.
an ill wind that blows no good
Just in case anyone's missed it, the Ares I-X is going to attempt again on Wednesday between 8 a.m. EDT and noon EDT.
Let's hope the weather works out better (well, and the missing piece from the top); I waited the whole night for the darn thing and it didn't even happen! :P
Currently launch is planned to take place at between 8.45 and 9.00 EDT (between 1245Z and 1300Z)
