The digital Soyuz have roll control! The old Soyuz had to be pointed in the correct direction azimuth by rotating the launch platform.I have heard this for many years, but it does not seem obvious to me what benefit comes from twirling the Soyuz on the pad in terms of "pointing" the rocket.The trajectory calculation is reduced to 2 dimesions if the rocket has already pointed to the correct azimuth.How can a rocket be "pointed" in the correct azimuth? Is the nose tilted towards the right direction?

Is the nose tilted towards the right direction?The space shuttle takes off vertically, rolls about the vertical axis so the windows on top of the orbiter are pointing the right way, then gradually pitches over to horizontal and flies off to orbit.If you didn't want to roll the space shuttle after it was flying, you could theoretically mount the launch pad on a giant turntable so you could spin the shuttle around to orient it correctly before launch.

/Quite! The English transliteration is Soyuz, the French transliteration is Soyouz. Neither is correct, just canonical in those languages.

Just curious: what would be requried for a Soyuz (with crew) or Progress (with cargo) launch out of Kurou to ISS? Seriously, well, besides the delivery of the vehicles themselves with interfaces and with the ground support/personel? And the Soyuz-U with the LAS as opposed to cargo version (just looking at these photos of the Kourou infrastracture, not unlike the one at Baykonour) Thank you.
