NASA's Megarocket, the Space Launch System, Rolls Out To Its Launchpad 83
On Thursday, NASA's new giant rocket, the Space Launch System, emerged out into the Florida air, embarking on a torturously slow 11-hour journey to its primary launchpad at Kennedy Space Center. The Verge reports: It was a big moment for NASA, having spent more than a decade on the development of this rocket, with the goal of using the vehicle to send cargo and people into deep space. The rollout of the SLS was just a taste of what's to come. The rocket will undergo what is known as a wet dress rehearsal in April, going through all the operations and procedures it will go through during a typical launch, including filling up its tanks with propellant. If that goes well, then the rocket will be rolled back to NASA's Vehicle Assembly Building, the giant cavernous building where the SLS was pieced together. Following a few more tests, the rocket will be rolled back out to the launchpad ahead of its first flight, scheduled for sometime this summer at the earliest. You can view photos from the SLS's big debut embedded in The Verge's article.

It wouldn't have been a waste if they'd been able to deliver on time. In 2011, reusing shuttle-derived components to build a super-heavy launch vehicle in five years was plausible.
Remember, Block 1 of this thing was supposed to be delivered in 2016, and lift 95 tons to LEO; that's 50% more than Falcon Heavy in *expendable* mode, and more than any other operational system *as of today*.
The concept was almost sound, but had one fatal flaw: all the shuttle-derived bits were sourced non-competitively. Congress *mandated* SLS as a jobs program.

Because you're not looking at engine cost, you're looking at the contract cost for 18 of them which includes R&D for things like new controllers and restarting a production line. If by some miracle SLS launches more times than they have engines for the per-engine cost will likely be lower. I'm putting my money on there being fewer SLS launches than the Saturn V.

This is a contract *modification* adding engines to an existing contract. R&D and production line startup were in the original contract along with 6 engines. The modification adds 18 more engines at ~$100M each, or $400M for a full SLS core's set of engines.

They used to paint them white during early Space Shuttle missions (like on this photo: click [wikipedia.org]), but they stopped after realizing that the paint itself weighs about 0.5t IIRC, and that's a 0.5t you have to carry into space instead of payload.
