(Anybody else get the 'Right Stuff' theme music and visions of the end sequence of Coopers flight during that?)

No, because if Gordo ended up tumbling and looking right back at the Atlas, he wouldn't have made it.

Maybe it was all scheduled but the sep sequence was sort of depressive. I wonder if public and Congress will see it as a failure.

1.) Ares I-X flew straight as an arrow during ascent

2.) The REAL upper stage on Ares I will still be moving forward (on its OWN propulsion) once the first stage separates from it.  Also, if artist concepts and online videos are anything to go by, the upper stage will have its own separation motors to help push it away from the FS after SRB burnout.

1) Unless you count the apparently excessive "pad avoidance" maneuver.


By what criteria have you judged the PAM to be "apparently excessive"? Have you data on how big it was supposed to be?

Just be grateful that I-X didn't cork-screw into the launch tower as many people here feared. :)

The rocket did tilt a few degrees right after liftoff but there's nothing to worry. I really love the bright jet and the thunderous sound as it cleared the sky. We're one step closer to the Moon and Mars :)

Honestly to me looks like all went pretty much as planned, tumbling included. We have to see if the parachute worked well.

Ciao!

Just ask yourself.... With that liftoff tilt and that separation - even with separation motors - Do you think people should fly on that?

This test has almost no resemblance to Ares-I, thus nothing about it would affect my decision to fly on Ares-I or not.

Then what is the point of the launch?  :D Of course it is intended to match a real Ares I flight as much as possible.

2) There is a delay between staging and second stage ignition, to prevent the motor's exhaust from rebounding off the first stage and potentially damaging the second stage.  The ullage motors on the second stage will impart a slight acceleration, but only to settle propellant in the tanks prior to stage ignition. The 1st stage will (and did today) have booster separation motors -- essentially retro-rockets at the base of the aft skirt.


The Russians ignite the second stage while the core stage is still accelerating, just before MECO. That ensures that the US propellants are settled prior to ignition.

The shot from LC-39A was pretty, I'll give it that.

it's hard to say (much like LCROSS).

Speaking of which. With their two analyzing weeks more than over, have there been clearer results lately?

The CNN guy was quite excited.   It's a good day for NASA.

 Even worse was the separation......

This separation was as expected.  The USS didn't have any live thrusters, so it entered a tumble.  The booster fired its sep motors, followed immediately by its tumble motors *as planned*.  That sent it into a tumble *as planned*. 

We're just not used to seeing a test like this.

The flight was stable in pitch, yaw, and roll.  The sep was clean.  The stage appears to have parachuted to recovery.

It looks like a very successful test flight, assuming the telemetry flowed well for data downlink.

With regard to the sound of the launch... It sounds distinctly different from a shuttle launch. With the lack of SSME's contribution, there is simply a big BOOM, and then it's off! Spectacular.

I love hearing the sound of the moment of ignition without the masking noise of the SSME's.

The number of times people have been asking that question...  :P

Ares 1-X had rather little to do with Ares 1, as it didn't really have that much actual Ares 1-hardware, if any. Thrust and aerodynamic loads will all be different on the actual vehicle, if it ever flies.
