Does anyone have more info on the 1.5m tall "raising cylinder"? Is it made of the same Al-alloy as the fairing or the skin of the Vehicle equipment bay? The Launch kit hints that the cylinder's mass might be around 450 kg (11.2t - satellite mass - SYLDA mass) - is this about right?Since the raising cylinder's purpose seems to be to increase the fairing volume (height), are there, e.g., any special internal rails to guide SYLDA during its ejection sequence?Does the change of the center of gravity have an effect on ESC-D Cryotechnic upper stage control and guidance? Was there, e.g., a new SW requirement, or was the (original) guidance system sufficiently flexible to cover a wider range of (forward) center of gravity positions?And finally, what will be the total height of the "launcher"? 53.5m? 54m? 54.5m?
