SLS launch sequence?

[Pawelk198604]

I wonder does it would be similar to STS or Saturn V sequence.

You know Ignition Sequence start and so on

Since its engines are the same as the STS, I'd assume that the launch sequence is fairly similar to that of the STS.

It would not be Saturn V engines, i heard that NASA planed to retrofit their own F-1 Engines, they even steal some of them from museums exhibitions for testing

Not, F-1. SLS will use Saturn-era engines, but J2-Xs, much more refined (and almost incompatable) versions of the old J-2s. However, they did steal the SSMEs from museums, (or take them out before being sent to museums) for use in SLS.

F-1s were planned to be used in the SLS Block II Boosters, but they switched back to using advanced solids instead.

Too bad

J2-X is not planned for use on SLS either. The EDS design was replaced by an RL-10-powered version called EUS.

J2-X has been cancelled.

J2-X has been cancelled.

Ok, thanks. Was unaware of that.

It's actually good that this happened- no need to develop another engine for sls.

[Nibb31]

But they are still developing a whole new upper stage.

[SargeRho]

J2-X has been cancelled.

No, it hasn't. Its development has been completed, and it's now been shelved until it's needed.
