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. It was a big moment for NASA, having spent more than a decade on the development of this rocket, with the goal of using it to send cargo and people into deep space.

The launch of the SLS was just the beginning. In April, the rocket will undergo a wet dress rehearsal, going through all the procedures and operations it will go through during a typical launch, including filling up its tanks with propellant. The rocket will be rolled back to NASA's Vehicle Assembly Building if it goes well. The first flight of the rocket will take place this summer, after a few more tests.

There is some time before this megarocket sees space. For the first time in years, NASA employees, guests, and media were able to see the vehicle for the first time with their own eyes yesterday. There are photos from the SLS's big debut.
