Thanks to Chris G for specifically asking about the sep dynamics.

I mean of vehicles that have actual powered upper stages..rather than dummy simulators. I meant powered in that respect, as in real rather than dummy.

Quote from: ApolloLee on 10/28/2009 03:04 pm 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*. - Ed Kyle
Even worse was the separation......
I watched the launch from all the available views and noticed a few things that I hope the experts on here can comment about.

The question is not whether the first stage tumbled - everyone knows that was supposed to happen as a planned part of the recovery process. At the press conference just completed it was specifically stated that the second stage tumble was unexpected. That's what was being referred to. It could be a lot of things, aerodynamic effects, proximity aero, recontact, etc.

Most Online Ever: 2064 (Today at 03:58 PM)There is a Fark.com link to NSF on their "Geek" sub-page -- don't know whether it had anything to do with the outage but Fark links have spiked many sites in the past.
Fundamentally that was a success, SpaceX-esque staging notwithstanding . They controlled an inline Shuttle SRB successfully and safely from launch to separation. Staging, Thrust Oscillation, Acoustics, Money, fundamentally these can all be solved given the will and time but the concept was proved today and the MSFC Stick boys and girls can walk a little prouder today whatever the future holds, Congratulations !
Q: Why no visual on chute deploy? With a test as smooth as this, what are your thoughts on "selling" this rocket.A: ...We are working from Augustine report. Have been instructed to continue on current path. This test will be valuable no matter what happens in the future.
