Same reason i roll while in KSP? So i know which way is up XD

I learned very quickly playing KSP that my space shuttle build needs to roll in similar fashion to the real deal.

Why don't they put the rocket on the launch pad the other way round so it doesn't need to roll? I get the impression that the launch complex was built north/south and the rocket made with the door on a particular side, rather than with the launch azimuth in mind.

What does "gimbal vectors are in line with each other relative to center of mass" mean?

Just to clarify, during the gravity turn, what direction are astronauts heads pointing from the horizon (up or down). Shuttle launches have astronauts in heads down position during gravity turn; what was Apollo's?

Great vid. I as well had difficulty with azimuth and inclination. Thx. I wonder if SpaceX would separate payload fairings on the X axis for fairing recovery. On the X axis, each fairing is inherited with different altitudes upon separation and in combination with drogue shoots would give enough time for the recovery ship, Ms Tree, to maneuver and capture both segments. It's just a semi-educated guess, but what does everyone think?

Wtf is going on with your axis. Who puts the x axis vertical?

This little organization called NASA I guess 🤷‍♂️ - science.ksc.nasa.gov/shuttle/technology/sts-newsref/sts_coord.html Don’t forget, the frame a reference is the same as the astronauts in the command module, they’re not going up on ascent, they’re going forward.

I NEVER knew that the Shuttle's SRB's could gimble!!! Makes so much more sense!

One word Gyroscope eg Earths north south pointing one way you have to aim the rocket to be able to point in the direction you want to go

13:28 does it have something to do with the docking maneuver?

Idk I’m not a expert but i think it is to stop it from spinning on its y axis

I was always confused by the shuttle's roll program. I mean, I understood why it did roll for the reasons you mentioned, but I don't understand why they had it roll so much; almost a full 180 degrees. Why didn't they just construct the tower & service structure on the pad such that the orbiter was facing mostly towards it's usual azimuth?
The best I can guess -- and is probably why -- is that they were essentially re-using the Apollo VAB and crawler, and with the tank & SRBs being assembled first, then moving the orbiter in later, that necessitated the vehicle being in that particular direction.

Just before this summer holliday started, I discovered and subbed to your channel.
Then, unexpectedly I was in Russia, and I had the chance to see one of the only (flown) Burans up close and personal.
It was a fantastic experience and I never would have known how lucky I was without your explanation.
Thanks and greeting from the Netherlands.
PS I took a lot of pictures. I really had a chance to get up close. If you want them can you please leave a comment on one of my random yt channel vids?
I will post my email in the comment section there.
I don’t really want to post it here. Hope you understand :)

The shuttle ALSO needed to be on the bottom so it could better control the up/down attitude by using it's throttle. If it were on top it could only make it go down by adding throttle. It could not help it go up.....
When it rolls, it aligns its course program.

At 14:20, we can see chunks of something white coming out of the nose of the shuttle, right in front of the forward windows. Afterwards, there appear to be tubes running through the nose, as if the white chunks were plugging the tubes. Can you explain this?
My initial thought is that this has something to due with the aerodynamics and the change in pressure as the shuttle accelerates and the atmosphere thins. It very much so appears to be intentional. Could this be a redirecting or breaking up of a shock wave, or perhaps nothing more interesting than a couple of instruments taking readings?

Was the command module and the Saturn V Y & Z axis opposite because the command module had to flip around and get the lunar lander?

I kinda skipped through it because I already knew. However, it is a good explanation - maybe a little too long - but good anyway.

0:29 if you look very carefully you can see the SRB nozzle gimbaling to roll the space shuttle. Reminds me of Orbiter Space Simulator where the default shuttle uses the RCS to roll.

It might have already been stated, but I wonder if SpaceX ejects it faring along the Y axis is to ease in recovery of them. They will come down one after the other in a straight line making recovery with a ship easier.

It's quite obvious. Rockets roll to keep their good side towards the cameras.

Not that I disagree but it does not make any sense. Too much BS commentary on the so called ROLL. If the rocket can stir with its exhausts then roll is irrelevant.
So why not just go straight up and turn when the rocket leaves the gravitational pull of the Earth to fine tune the arrival???
