mikegarrison Posted May 19, 2022 Share Posted May 19, 2022 LOL. They just called out that they have confirmation of a good MET on their internal clock. I guess they learned *that* lesson. Hey!

The entire graphical display is useless. No velocities, the progress bar doesn't move in an analog manner. I sure hope the software on Starliner is better than what is running the stream graphics, lol. It sure seemed like the boosters were dead weight for a lot longer than they needed to be. That was kind of strange. Quote Link to comment Share on other sites More sharing options...

I'd think. I know SRBs are hard to "tune" but it was my understanding that the ability to tune these particular boosters in segments was part of their coolness. I may be thinking of another flavor Quote Link to comment Share on other sites More sharing options...

I think they have earned our trust that they know what they are doing. Understood, but I thought I'd seen the boosters separate sooner after flameout in prior launches. That was the point of my comment. Not critical, just curious what is up. I have no doubt ULA knows what they are doing Quote Link to comment Share on other sites More sharing options...

As said before, lifting them out of the thicker air where recontact may be an issue. The trade off for slanted nose comes on the solids; ULA need to go the kerbal way and slant them to aid in separation (j/k, I’m sure there’s other complications with that). It could be worse; one of the Indian launch vehicles has the core burn out before the boosters! (IIRC) Glad to hear it was apparently a successful launch though Quote Link to comment Share on other sites More sharing options...
