Hello everybody. Read the news storys all the time but first time on the forum. Sorry for the stupid question but why do the SSMEs take a few seconds to ignite and power up and the SRBs fire up almost immediately?Awesome video.

Because of the way liquid v. solid engines work.
But Delta 4's are liquid and that seemed to go up straight away too?
Big engines tend to need several seconds to really get going.

Hey guys !Just found this thread, and had to say, the video is just great !One question though : what about the water deluge system on the SSME ? we can see the rainbirds flooding the SRB side of the MLP with water, but what about the SSME ?I guess there must be some water deluge there too ?I've seen it already, but couldn't find the source anymore..
There is a deluge in the SSME duct but there is not one needed on the top side. The rainbirds are not there for the SRB exhaust, notice that they do not "come on" until after liftoff. The rainbirds cover the deck of the MLP with water so that the acoustic noise from the vehicle does not reflect of the deck and damage the vehicle.
