Space Launch System (SLS)

  1. 1. Space Launch System (SLS)Marshall Space Flight Center<br />Todd May<br />SLS Program Office <br />March 30, 2011<br />
  2. 2. NASA: Why America Explores Space<br />Innovation and Education Are Keys to Winning the Future<br />Public Engagement<br />Scientific Knowledge<br />Global Partnerships<br />Exploration Preparation<br />Economic Prosperity<br />National Security<br />National Aeronautics and Space Administration<br />7980_Goddard_Symposium.2<br />
  3. 3. Policies and Processes<br />2009<br />2010<br />2011<br />Augustine Committee Final Report<br />(October)<br />FY11 Budget Submittal<br />(February)<br />2011 NASA Strategic Plan<br />(February)<br />Goal 1: Extend & sustain human activities across the solar system. <br />Objective 1.3: Develop an integrated architecture & capabilities for safe crewed & cargo missions beyond LEO.<br />2010 U.S. Space Policy<br />(June)<br />FY12 Budget Submittal<br />(February)<br />"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."<br />”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…"<br />President Signs Budget Authorization<br />(October)<br />"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."<br />"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."<br />Implementing the Nation’s Space Agenda<br />National Aeronautics and Space Administration<br />7980_Goddard_Symposium.3<br />
  4. 4. Expanding Humanity’s Frontiers of Discovery<br />Safely fly & retire the Space Shuttle & maintain safe access for humans to low-Earth orbit (LEO) as we fully utilize the International Space Station.<br />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).<br />Source: NASA FY12 Budget<br />To reach for new heights and reveal the unknown <br />so that what we do and learn will benefit all humankind. <br />— NASA 2011 Strategic Plan<br />National Aeronautics and Space Administration<br />7980_Goddard_Symposium.4<br />
  5. 5. Capabilities-Driven Framework<br />Mars Missions<br />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. <br />35A<br />35B<br />Mars Elements<br />6: Enable Mars Missions<br />DISTANCE<br />Full Capability NEA Missions<br />34B<br />Space Exploration Vehicle (SEV)<br />Solar Electric Propulsion (SEP)<br />5: Enable Deep Space Missions<br />Minimal NEA Missions<br />Long Duration Habitation Needed<br />34A<br />Deep Space Habitat (DSH)<br />4: Enable Long Duration Missions<br />Lunar Surface Missions<br />Crew EVA Suit Block 2<br />33C<br />Lunar Lander & GPOD<br />Advanced Propulsion Needed<br />3: Enable Lunar Surface Missions<br />Lunar Flyby &Orbital Missions<br />33A<br />33B<br />GEO/HEO Missions<br />32A<br />32B<br />High Thrust in-Space Propulsion Needed<br />Cryogenic Propulsion Stage (CPS)<br />2: Enable Missions Beyond LEO<br />KEY<br />Robotics & EVA Module (REM)<br />Crew EVA Suit Block 1<br />Capability Gates<br />New LEO Missions<br />31A<br />Candidate Destination<br />Multi-Purpose Crew Vehicle (MPCV)<br />DRM<br />Ultimate Destination Goal<br />SPACE LAUNCH SYSTEM - HLLV<br />DRM<br />Element Capability<br />1: Enable New LEO Missions<br />MISSION DURATION<br />Increasing Flexibility and Fostering Sustainability<br />National Aeronautics and Space Administration<br />7980_Goddard_Symposium.5<br />
