During the Space Launch System flight the boosters will provide more than 75 percent of the thrust needed to escape the gravitational pull of the Earth, the first step on NASA's Journey to Mars.

“At her job, Maria Torero cares for sick human beings. At home, she lavishes love on slowly dying cats – 175 of them at last count. The 45-year-old nurse has turned her two-story, eight-room apartment into a hospice for cats with feline leukemia, scattering it with scores of feeding dishes and at least two dozen boxes litter boxes. Some have suggested she shelter healthy cats instead. “That's not my role”, she told The Associated Press. “I'm a nurse. My duty is to the cats that nobody cares about”. She said that “people don't adopt adult cats, especially if they are terminally ill”. – Franklin Briceno via Associated Press. (Photo by Martin Mejia/AP Photo)

“The Space Launch System, or SLS, is a Shuttle-Derived heavy launch vehicle being designed by NASA, following the cancellation of the Constellation Program, to replace the Space Shuttle after its retirement. The NASA Authorization Act of 2010 envisions the transformation of the Ares I and Ares V vehicle designs into a single launch vehicle usable for both crew and cargo. It is to be upgraded over time with more powerful versions. The proposed SLS is visually similar to the legacy Saturn V booster and in particular the proposed, two-stage, Saturn INT-20”. – Wikipedia

NASA's new rocket design will reportedly cost about $35 billion and be ready to for test launch in 2017. According to NASA, the rocket will be used to carry Orion Multi-Purpose Crew Vehicle as well as cargo and science experiments to earth's orbit, as a backup for the space station and possibly destinations beyond that.
