4)Structure Evolution of the Universe Explain the structure in the Universe forecast our destiny Explore the cycles of matter energy in the evolving universe Examine the ultimate limits of gravity energy in the universe Earth Science with the goal being to obtain a scientific understanding of the entire Earth system on a global scale practical goal to enable us to predict both short long term changes in biosphere dy Human Space Flight with the goal of opening the space frontier by exploring, using and enabling the development of space and expanding the human experience into the far reaches of space Aerospace Technology with the goal of achieving the full potential of space for all human endeavors through affordable space transportation Note the following points: The policy goals for NASA are to nhance knowled help understand human influence on the environment conduct human space flight for scientific, commercial and exploration reasons explore space technologies applications in support of economic competitiveness Thus nasa will 1)Operate ISS primarily as a means to support a future decision on the desirability of further human exploration(read Mars but this is the last mention in the space policy on human exploration of Mars) 2)Help develop an RLV to enable U.S. to leapfrog launch competitors 3)Focus on robotic exploration of Mars 4) Focus on reducing cost by innovative technologies(this arose from the concern that NASA focused only on science return not cost) 5)Always keep safety in mind for ISs shuttle (i.e. there will be no more Challenger disasters 6)Not compete with the private sector(especially JPL, a concern of the past) 7)Get out of non-core things that can be provided by the space section (i.e. space communication4) Structure & Evolution of the Universe: - Explain the structure in the Universe & forecast our destiny. - Explore the cycles of matter & energy in the evolving universe. - Examine the ultimate limits of gravity & energy in the universe. Earth Science with the goal being to obtain a scientific understanding of the entire Earth system on a global scale. - practical goal to enable us to predict both short & long term changes in biosphere dynamics. Human Space Flight with the goal of opening the space frontier by exploring, using and enabling the development of space and expanding the human experience into the far reaches of space. Aerospace Technology with the goal of achieving the full potential of space for all human endeavors through affordable space transportation. - Note the following points: The policy goals for NASA are to: - enhance knowledge - help understand human influence on the environment - conduct human space flight for scientific, commercial and exploration reasons - explore space technologies & applications in support of economic competitiveness. Thus NASA will: 1) Operate ISS primarily as a means to support a future decision on the desirability of further human exploration (read Mars but this is the last mention in the space policy on human exploration of Mars). 2) Help develop an RLV to enable U.S. to leapfrog launch competitors 3) Focus on robotic exploration of Mars 4) Focus on reducing cost by innovative technologies (this arose from the concern that NASA focused only on science return not cost) 5) Always keep safety in mind for ISS & shuttle (i.e. there will be no more Challenger disasters) 6) Not compete with the private sector (especially JPL, a concern of the past) 7) Get out of non-core things that can be provided by the space section (i.e. space communication)
