Honors Alum and Astronaut Hawley Shares Space Shuttle Experiences
Winter 2010-2011 Hthe onO read A newsletter for alumni, students and friends of the University of Kansas Honors Program From the Director t this time of year, Ait is traditional to give thanks for the gifts life has brought us. I am so grateful to be able to spend my days surrounded by bright, motivated and energetic young people. The students in KU’s Honors Program never cease to amaze and move me with their ideas as well as their ideals, and their commit - ment to making a difference in the world. The staff and faculty are dedicated to creating an environment in which these individuals can be nurtured and thrive. Our goal is to provide a set of transfor - mational experiences that are tailored to n a each student’s unique interests and tal - g i l l ents. For some, working closely with a u M y l faculty member on research is that trans - i m formative experience. For others, it’s E Megan McDonald and Steve Hawley talk following his Alumni Lecture spending a semester abroad or engaging in significant service to the community. And for many, it’s all of these things and more. It is a great pleasure to watch these students transform from tentative first- year students to supremely confident and Honors alum and astronaut competent seniors and know the Univer - sity Honors Program played a significant Hawley shares Space role in that transformation.

Chandra Booklet
Chandra X-Ray Observatory What is Chandra? Chandra is the third of NASA’s Great Observatories along with the Compton Gamma Ray Observatory and Hubble Space Telescope. It is the largest and most sophisticated X-ray observatory ever constructed. After it is launched into orbit around Earth, Chandra will be able to detect X-ray sources that are billions of light years away and produce images twenty-five times sharper than the best previous X-ray telescope. Chandra’s focusing power is equivalent to the ability to read the headline of a newspaper at a distance of half a mile! Mission Specifications Size: 45.3 ft x 64.0 ft Antennas: two low-gain, conical log (solar arrays deployed) spiral antennas Weight: 10,560 pounds Frequencies: transmit 2250 MHz, receive 2071.8 MHz Orbit: 6,200 x 86,000 miles Command Link: 2 kilobits per second (kbps) 28.5 deg. inclination Ascending node: 200 degrees Data Recording: solid state recorder; 1.8 gigabits (16.8 hrs) recording capability Argument of perigee: 270 degrees Downlink: downloaded typically every Operations: eight hours Life: minimum 5 years Contingency Mode: 23 kbps Power: two 3-panel silicon solar arrays (2350W) Safing: autonomous operation three 40 amp-hour nickel hydrogen batteries The Chandra Launch - STS 93 Astronaut Crew The Chandra Observatory will be carried into orbit by the Space Shuttle Columbia, on shuttle mission STS 93.

Social, Cultural, and Educational Legacies
NASA Reflects America’s Changing Opportunities; Social, NASA Impacts US Culture Education: Inspiring Cultural, and Students as Only NASA Can Educational Legacies Social, Cultural, and Educational Legacies 459 NASA Reflects The Space Shuttle, which began flying in 1981 and ushered in an entirely new human spaceflight program, was a watershed for cultural diversity America’s within NASA and had substantial cultural impact outside the realm of Changing spaceflight. In the 1950s and 1960s, opportunities for American women and minorities were limited as they were often segregated into pink Opportunities; collar and menial jobs. NASA’s female and minority employees faced NASA Impacts similar obstacles. The Space Shuttle Program opened up opportunities US Culture for these groups—opportunities that did not exist during Projects Mercury and Gemini or the Apollo and Skylab Programs. NASA’s transformation was a direct consequence of a convergence of events Jennifer Ross-Nazzal Shannon Lucid that happened in the 1960s and 1970s and continued through the Helen Lane following 3 decades. These included: public policy changes instituted on the national level; the development of a spacecraft whose physical capabilities departed radically from the capsule concept; and an increase in the number of women and minorities holding degrees in the fields of science and engineering, making them attractive candidates for the space agency’s workforce. Over the course of the program, the agency’s demographics reflected this transformation: women and minorities were incorporated into the Astronaut Corps and other prominent technical and administrative positions. The impact of NASA’s longest-running program extends beyond these dramatic changes. -
Joel R. Primack, Distinguished Professor of Physics Emeritus, UCSC
Joel R. Primack, Distinguished Professor of Physics Emeritus, UCSC Research accomplishments: I think of myself as a theoretical physicist with broad interests. My Princeton senior thesis under Gerald E. Brown's supervision was the first modern theory of nuclear fission (Primack, PRL 1966). Although it overturned the liquid drop model of Niels Bohr and John Wheeler (1939), Wheeler gave it highest marks and I graduated as the valedictorian of my class. As an undergraduate I also published papers on plasma fluid dynamics, based on research as a summer employee at Jet Propulsion Lab. I worked on theoretical particle physics as Sid Drell’s grad student at the Stanford Linear Accelerator Center (SLAC) 1966-70, as a Junior Fellow of the Harvard Society of Fellows 1970-73, and in my first decade at UCSC (1973-1983). Drell suggested that I figure out what was wrong with the apparent failure of the Drell-Hearn sum rule applied to nuclei, so Stan Brodsky I wrote fundamental papers (1968-69) on how to treat the electromagnetic interactions of composite systems such as nuclei. Tom Appelquist and I studied form factors in field theory (1970-72). Appelquist, Helen Quinn, and I wrote some of the first papers on the SU(2)xU(1) electroweak theory (1972-73). With Ben Lee and Sam Trieman I did the first calculation of the mass of the charmed quark (1973), and Abraham Pais and I (1973) showed that CP violation arises in the cross term between first and second order perturbation theory. Sam Berman and I (1974) showed that polarized electron scattering allows a high-precision test of SU(2)xU(1), which resulted in the SLAC experiment whose success helped justify the Nobel Prize for Glashow, Salam, and Weinberg.
