President Signs Budget Authorization(October)
FY12 Budget Submittal(February)”U.S. access to space depends…on launch capabilities.
U.S. Government payloads shall be launched on vehicles manufactured in the United States unless exempted…"
"A heavy-lift launch capability to LEO, combined with the ability to inject heavy payloads away from the Earth, is beneficial to exploration and it also will be useful to the national security space and scientific communities."
"Directs NASA to initiate development of an SLS with the capability to lift between 70 and 100 tons into LEO without an upper stage, to carry an Earth departure stage bringing the total lift capability to 130 tons or more, to lift the MPCV, and to serve as cargo backup for ISS cargo requirements or crew delivery not otherwise met by available commercial or partner-supplied vehicles. Sets a goal for core operational capability by 12/31/16."
Goal 1: Extend & sustain human activities across the solar system.
Objective 1.3: Develop an integrated architecture & capabilities for safe crewed & cargo missions beyond LEO.
"NASA will continue architecture planning for the MPCV capable of taking human explorers to distant locations throughout the inner solar system. The SLS Program will develop the heavy-lift vehicle that will launch the MPCV, other modules, and cargo for these missions."

Expanding Humanity’s Frontiers of Discovery
To reach for new heights and reveal the unknown so that what we do and learn will benefit all humankind.
— NASA 2011 Strategic Plan
♦ Safely fly & retire the Space Shuttle & maintain safe access for humans to low-Earth orbit (LEO) as we fully utilize the International Space Station.
♦ Lay the foundation for humans in deep space—the Moon, asteroids, eventually Mars—through development of a powerful, evolvable Space Launch System (SLS) and Multipurpose Crew Vehicle (MPCV).

Capabilities required at each destination are determined by the mission and packaged into
elements. This approach seeks to package these capabilities into a logical progression of
common elements to minimize DDT&E and embrace incremental development.
