Vehicle Cam 1 proved no good for staging, lost signal right at staging.
Perhaps Chris (or Chris) knows if all the cameras are being recorded on the booster...dependent on recovery, but if that's the case, there should be something to see.

The thing is they need to make sure there is NO contact with a live 2nd stage with a J2X in it, that could ruin your whole day.

But it was a good flight, much smoother than I was expecting, just did not know how an Shuttle SRB would do solo.  Had a quite pronounced "lets make sure we dont hit the tower" maneuver, and very fast.

Also did not notice much in the way of "rotation" at all really.

Yeah, they will have to be significant ullage motors
Aren't ullage motors just designed to settle the fuel in the stage?
Keith
I am sure the final flight vehicle, if it ever is built, will include ullage motors.  The Saturns did and not only for pushing the upper stage away but also to settle the propellant in the upper stage as mentioned.  I believe this second stage had no such active component so the odd separation really doesn't seem to be that odd to me.  Also remember the recent SpaceX failure due to impact between stages at separation.

You can see the exhaust from the roll control thrusters in rocket cam video

On to Vehicle Camera 2 (WITH AUDIO!)

Got a few bits of the parachute deploy sequence at the end of the Cam 1 replay.

It did give a short glimpse of the upper stage after staging, just as the tumble motors fired.  Upper stage looked pretty stable at the time (linear with the booster, anyway), but we need more data.

Good day for nasa as well as the constellation program.

That is debatable.

Cam 2 has some audio...interesting...

Also a lot of dropouts...

Yes. The ullage motors are for settling fuel - and they are not gimballed - they have no ability to keep the vehicle pointy end forward. They are not very powerful. I can't recall offhand if there are attitude control jets on second stage - that might help normally. On a real flight, the second stage J2 will not fire immediately (and will not be able to control the stage), so the second stage will need to be stable or stabilized for a few seconds after sep. Also, the J2 nozzle will be sticking out back and recontact with that will have to be avoided. It was expected that eventually for this test the upper stage would tumble, but it wasn't supposed to do what it did.

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 first and upper stages will not separate at the same location on Ares I as on I-X

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.

The public and Congress should see this flight as MORE of a success than a failure.

Came back for a couple frames with the USS visible, no readily apparent damage but not enough evidence either way.

I'm a huge fan, but I find it interesting the vehicle cam replays cut out between ignition and tower clear and again at first and upper stage sep.  Coincidence?  Makes me wonder if contact was made with launch service structure as wells as recontact with upper stage.

Make no difference to me as I already can't wait for Ares 1-Y!

The USS yaw did look pretty severe on the angle that was shown for launch, however it doesn't look as bad on some of the replays.

Also remember we are used to seeing separations of powered 2nd stages...

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

Vehicle Camera 2 still no good for separation.. again, if they have recorded it on the vehicle and have the raw vehicle video, that'll be good.

Yes, pretty launch though I have to think that tilt was more than expected... Even worse was the separation......

For a test of a vehicle designed to be unmanned, I could almost accept this... But this vehicle is supposed to carry PEOPLE to orbit.

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

I lost video briefly during the separation dynamics, so hopefully will get to see this better...

Sorry if this was already covered in thread, still catching up.  The NASA TV feed (over satellite) had trouble right after separation, for about 20 seconds.  I'll be checking my recordings to see what the deal was, but there was definitely a problem there.  Internet may have been fine, but cable would definitely have seen the problem.
PSA #1: EST does NOT mean "Eastern Time".  Use "Eastern" or "ET" instead, all year round, and avoid this common error.  Google "EST vs EDT".
PSA #2: It's and its: know the difference and quietly impress grammar pedants.  Google "angry flower its" .  *** See profile for two more NSF forum tips. ***

Upper stage video doesn't show separation, but I think the upper stage was *supposed* to be LOS at separation -- all the electronics were in the first stage.
