Charles Bolden, NASA Administrator Science and Technology Policy Institute Washington, DC August 14, 2012 • Thank You, Mark [D
Charles Bolden, NASA Administrator Science and Technology Policy Institute Washington, DC August 14, 2012 Thank you, Mark [Dr. Mark Lewis] for that gracious introduction and for the opportunity to talk with you about some of the many exciting things that are happening at NASA. This is my first public speaking opportunity since last week’s historic landing of the Curiosity rover on the surface of Mars – so I can’t help but begin by sharing our excitement about this success and what it means going forward. I hope you all got a chance to see this historic achievement and are following the steady flow of stunning pictures on NASA.gov. 1 As you may know, Curiosity is the most sophisticated rover ever built and sent to another planet. For the next two years, it will seek to answer ago-old questions about whether life ever existed on Mars – or if the planet can sustain life in the future. The landing, which was dubbed “Seven Minutes of Terror,” was the most difficult and challenging mission in the history of robotic planetary exploration. New technologies previously unused or proven were created for this journey. Quite frankly, we did not know if we would make it, but we went for the gold and scored a perfect 10. This was an amazing achievement, made possible by a team of scientists and engineers from around the world and led by the extraordinary men and women of NASA and our Jet Propulsion Lab in Pasadena, California. 2 I know that this group is very interested in the cost-benefit analysis of the nation’s investment in science and technology. -

Solar System Exploration
Theme: Solar System Exploration Cassini, a robotic spacecraft launched in 1997 by NASA, is close enough now to resolve many rings and moons of its destination planet: Saturn. The spacecraft has now closed to within a single Earth-Sun separation from the ringed giant. In November 2003, Cassini snapped the contrast-enhanced color composite pictured above. Many features of Saturn's rings and cloud-tops now show considerable detail. When arriving at Saturn in July 2004, the Cassini orbiter will begin to circle and study the Saturnian system. Several months later, a probe named Huygens will separate and attempt to land on the surface of Titan. Solar System Exploration MAJOR EVENTS IN FY 2005 Deep Impact will launch in December 2004. The spacecraft will release a small (820 lbs.) Impactor directly into the path of comet Tempel 1 in July 2005. The resulting collision is expected to produce a small impact crater on the surface of the comet's nucleus, enabling scientists to investigate the composition of the comet's interior. Onboard the Cassini orbiter is a 703-pound scientific probe called Huygens that will be released in December 2004, beginning a 22-day coast phase toward Titan, Saturn's largest moon; Huygens will reach Titan's surface in January 2005. ESA 2-1 Theme: Solar System Exploration OVERVIEW The exploration of the solar system is a major component of the President's vision of NASA's future. Our cosmic "neighborhood" will first be scouted by robotic trailblazers pursuing answers to key questions about the diverse environments of the planets, comets, asteroids, and other bodies in our solar system. -

Launching a New Era of Exploration Welcome to Langley NASA Langley had a banner year in 2012 as we helped propel the nation toward a new age of air and space. From delivering on missions to creating new technologies and knowledge for space, aviation and science, Langley continued the rich tradition of innovation begun 95 years ago. Langley is providing leading-edge research and game-changing technology innovations for human space exploration. We are testing prototype articles of the Orion crew vehicle to optimize designs and improve landing systems for increased crew survivability. Langley has had a role in private-industry space exploration through agreements with SpaceX, Sierra Nevada Corp. and Boeing to provide engineering expertise, conduct testing and support research. Aerospace and Science With the rest of the world, we held our breath as the Curiosity rover landed on Mars – with Langley’s help.

The Space Race
The Space Race Aims: To arrange the key events of the “Space Race” in chronological order. To decide which country won the Space Race. Space – the Final Frontier “Space” is everything Atmosphere that exists outside of our planet’s atmosphere. The atmosphere is the layer of Earth gas which surrounds our planet. Without it, none of us would be able to breathe! Space The sun is a star which is orbited (circled) by a system of planets. Earth is the third planet from the sun. There are nine planets in our solar system. How many of the other eight can you name? Neptune Saturn Mars Venus SUN Pluto Uranus Jupiter EARTH Mercury What has this got to do with the COLD WAR? Another element of the Cold War was the race to control the final frontier – outer space! Why do you think this would be so important? The Space Race was considered important because it showed the world which country had the best science, technology, and economic system. It would prove which country was the greatest of the superpowers, the USSR or the USA, and which political system was the best – communism or capitalism. https://www.youtube.com/watch?v=xvaEvCNZymo The Space Race – key events Discuss the following slides in your groups. For each slide, try to agree on: • which of the three options is correct • whether this was an achievement of the Soviet Union (USSR) or the Americans (USA). When did humans first send a satellite into orbit around the Earth? 1940s, 1950s or 1960s? Sputnik 1 was launched in October 1957. -
PHYSICS of ARTIFICIAL GRAVITY Angie Bukley1, William Paloski,2 and Gilles Clément1,3
Chapter 2 PHYSICS OF ARTIFICIAL GRAVITY Angie Bukley1, William Paloski,2 and Gilles Clément1,3 1 Ohio University, Athens, Ohio, USA 2 NASA Johnson Space Center, Houston, Texas, USA 3 Centre National de la Recherche Scientifique, Toulouse, France This chapter discusses potential technologies for achieving artificial gravity in a space vehicle. We begin with a series of definitions and a general description of the rotational dynamics behind the forces ultimately exerted on the human body during centrifugation, such as gravity level, gravity gradient, and Coriolis force. Human factors considerations and comfort limits associated with a rotating environment are then discussed. Finally, engineering options for designing space vehicles with artificial gravity are presented. Figure 2-01. Artist's concept of one of NASA early (1962) concepts for a manned space station with artificial gravity: a self- inflating 22-m-diameter rotating hexagon. Photo courtesy of NASA. 1 ARTIFICIAL GRAVITY: WHAT IS IT? 1.1 Definition Artificial gravity is defined in this book as the simulation of gravitational forces aboard a space vehicle in free fall (in orbit) or in transit to another planet. Throughout this book, the term artificial gravity is reserved for a spinning spacecraft or a centrifuge within the spacecraft such that a gravity-like force results. One should understand that artificial gravity is not gravity at all. Rather, it is an inertial force that is indistinguishable from normal gravity experience on Earth in terms of its action on any mass. A centrifugal force proportional to the mass that is being accelerated centripetally in a rotating device is experienced rather than a gravitational pull. -
