NASA's Megarocket, the Space Launch System, Rolls Out To Its Launchpad

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.
