Aerospace Safety Advisory Panel
Aerospace Safety Advisory Panel Annual Report for 2009 NASA AEROSPACE SAFETY ADVISORY PANEL National Aeronautics and Space Administration Washington, DC 20546 VADM Joseph W. Dyer, USN (Ret.), Chair January 15, 2010 The Honorable Charles F. Bolden, Jr. Administrator National Aeronautics and Space Administration Washington, DC 20546 Dear General Bolden: Pursuant to Section 106(b) of the National Aeronautics and Space Administration Authorization Act of 2005 (P.L. 109-155), the Aerospace Safety Advisory Panel (ASAP) is pleased to submit the ASAP Annual Report for 2009 to the U.S. Congress and to the Administrator of the National Aeronautics and Space Administration (NASA). ASAP members believe that NASA and the Administration face significant challenges for the Nation’s space program. Following the precedent set in 2008, the ASAP again pro - vides this letter report in lieu of the lengthier annual report submitted in previous years. This letter report is based on the Panel’s 2009 quarterly meetings (and public session minutes), fact-finding meetings, and formal recommendations, as well as ASAP members’ past experiences. In Section II of this report, the Panel provides a summary of key safety-related issues that the Agency confronts at this time. The most important relate to the future of the Nation’s human space flight program, and the ASAP hopes to encourage key stakeholders to immediately consider the critical decisions relating to this mission. Significant issues include human rating requirements for potential commercial and international entities, extension of Shuttle beyond the current manifest, workforce transition from the Shuttle to the follow-on program, the need for candid public communications about the risks of human space flight, and the more aggressive use of robots to reduce the risk of human exploration. -
Ozone Therapy: Beyond Oxygen the Most Needed Adjunct to Veterinary Medicine Introduction of Ozone
Ozone Therapy: Beyond Oxygen The Most Needed Adjunct to Veterinary Medicine Introduction of Ozone Margo Roman, D.V.M., CVA, COT, CPT MASH Main St Animal Services of Hopkinton Hopkinton MA 01748 www.mashvet.com • OZONE is a trivalent oxygen molecule. Three O2 + electrical spark/ lightning= 2 O3. It is very reactive and will return to 3 O2 molecules giving high levels of O2. Healthy cells need Oxygen • Ozone is one of the most beneficial substances on this planet, and the BAD science you hear quoted on the news every night is causing you to subconsciously be afraid of nature, and therefore, a part of life itself. They tell you that somehow hydrogen plus nitrogen or sulfur equals ozone. H + N + S = 03? Not on this planet it doesn't! What is ozone? Simply, oxygen. Three atoms of nature's oxygen. It exists in a very active form for about 30 minutes before breaking down into two atoms of regular oxygen - by giving up one atom of singlet oxygen. Where does ozone come from? Nature. And nature is efficient. The new growth in the forests, the trees, the grass on your front lawn, and the plankton in the ocean are continually creating oxygen. • • If you have seen Inconvenient Truth, the Al Gore documentary on Global warming, there is one scene that brings it all together. In one section he discusses the CO2 levels over the Pacific Ocean. In addition to the original measurements that began in 1965, they were able to measure the levels from hundreds of years ago by taking samples from deep within glaciers. -
Arthur C. Clarke Fred Körper, SFGH-Treffen 21.02.2009
SF-Klassiker: Arthur C. Clarke Fred Körper, SFGH-Treffen 21.02.2009 Sir Arthur Charles Clarke (* 16. Dezember 1917 in Minehead, Somerset, England; † 19. März 2008 in Colombo, Sri Lanka) war ein britischer Science-Fiction-Schriftsteller. Durch den Film 2001: Odyssee im Weltraum von Stanley Kubrick, der auf einer Kurzgeschichte Clarkes beruht und dessen Drehbuch Clarke gemeinsam mit Kubrick schrieb, wurde er auch außerhalb der Science-Fiction-Szene bekannt. Clarke gilt als Visionär neuer Technologien, die er außer in Science-Fiction-Romanen und Kurzgeschichten auch in wissenschaftlichen Artikeln beschrieb. 1 Leben 2 Werk 2.1 Romane 2.2 Erzählungen 2.3 Kurzgeschichtensammlungen 2.4 Gemeinschaftswerke 2.5 Autobiografisches 3 Verfilmungen (Auswahl) 4 Clarke'sche Gesetze Leben Arthur Charles Clarke wurde am 16.Dezember 1917 in der Grafschaft Somerset im Südwesten Englands geboren. Von 1927 bis 1936 besuchte er die Huish's Grammar School in Taunton/Somerset und las bereits als Jugendlicher die Werke von H. G. Wells und Olaf Stapledon. Da Clarke aus finanziellen Gründen ein Studium zunächst verwehr blieb, ging er 1936 nach London und arbeitete dort zunächst im Staatsdienst. 1941 trat er als Radaroffizier in die Royal Air Force ein. Diese Erfahrungen liegen dem Roman Glide Path zugrunde. Seine Idee, geostationäre Satelliten zur technischen Kommunikation zu nutzen, die er 1945 unter dem Titel Extra-terrestrial Relays – Can Rocket Stations Give World- wide Radio Coverage? in der wissenschaftlichen Zeitschrift Wireless World veröffentlichte, erlebte 1964 mit dem Saetelliten Syncom 3 ihre Verwirklichung. Ihm zu Ehren wird daher der geostationäre Orbit auch „Clarke Belt“ beziehungsweise „Clarke Orbit“ genannt. Von 1946 bis 1948 studierte er Mathematik und Physik am Londoner King's College. -

Multisatellite Determination of the Relativistic Electron Phase Space Density at Geosynchronous Orbit: Methodology and Results During Geomagnetically Quiet Times Y
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 110, A10210, doi:10.1029/2004JA010895, 2005 Multisatellite determination of the relativistic electron phase space density at geosynchronous orbit: Methodology and results during geomagnetically quiet times Y. Chen, R. H. W. Friedel, and G. D. Reeves Los Alamos National Laboratory, Los Alamos, New Mexico, USA T. G. Onsager NOAA, Boulder, Colorado, USA M. F. Thomsen Los Alamos National Laboratory, Los Alamos, New Mexico, USA Received 10 November 2004; revised 20 May 2005; accepted 8 July 2005; published 20 October 2005. [1] We develop and test a methodology to determine the relativistic electron phase space density distribution in the vicinity of geostationary orbit by making use of the pitch-angle resolved energetic electron data from three Los Alamos National Laboratory geosynchronous Synchronous Orbit Particle Analyzer instruments and magnetic field measurements from two GOES satellites. Owing to the Earth’s dipole tilt and drift shell splitting for different pitch angles, each satellite samples a different range of Roederer L* throughout its orbit. We use existing empirical magnetic field models and the measured pitch-angle resolved electron spectra to determine the phase space density as a function of the three adiabatic invariants at each spacecraft. Comparing all satellite measurements provides a determination of the global phase space density gradient over the range L* 6–7. We investigate the sensitivity of this method to the choice of the magnetic field model and the fidelity of the instrument intercalibration in order to both understand and mitigate possible error sources. Results for magnetically quiet periods show that the radial slopes of the density distribution at low energy are positive, while at high energy the slopes are negative, which confirms the results from some earlier studies of this type. -

Positioning: Drift Orbit and Station Acquisition
Orbits Supplement GEOSTATIONARY ORBIT PERTURBATIONS INFLUENCE OF ASPHERICITY OF THE EARTH: The gravitational potential of the Earth is no longer µ/r, but varies with longitude. A tangential acceleration is created, depending on the longitudinal location of the satellite, with four points of stable equilibrium: two stable equilibrium points (L 75° E, 105° W) two unstable equilibrium points ( 15° W, 162° E) This tangential acceleration causes a drift of the satellite longitude. Longitudinal drift d'/dt in terms of the longitude about a point of stable equilibrium expresses as: (d/dt)2 - k cos 2 = constant Orbits Supplement GEO PERTURBATIONS (CONT'D) INFLUENCE OF EARTH ASPHERICITY VARIATION IN THE LONGITUDINAL ACCELERATION OF A GEOSTATIONARY SATELLITE: Orbits Supplement GEO PERTURBATIONS (CONT'D) INFLUENCE OF SUN & MOON ATTRACTION Gravitational attraction by the sun and moon causes the satellite orbital inclination to change with time. The evolution of the inclination vector is mainly a combination of variations: period 13.66 days with 0.0035° amplitude period 182.65 days with 0.023° amplitude long term drift The long term drift is given by: -4 dix/dt = H = (-3.6 sin M) 10 ° /day -4 diy/dt = K = (23.4 +.2.7 cos M) 10 °/day where M is the moon ascending node longitude: M = 12.111 -0.052954 T (T: days from 1/1/1950) 2 2 2 2 cos d = H / (H + K ); i/t = (H + K ) Depending on time within the 18 year period of M d varies from 81.1° to 98.9° i/t varies from 0.75°/year to 0.95°/year Orbits Supplement GEO PERTURBATIONS (CONT'D) INFLUENCE OF SUN RADIATION PRESSURE Due to sun radiation pressure, eccentricity arises: EFFECT OF NON-ZERO ECCENTRICITY L = difference between longitude of geostationary satellite and geosynchronous satellite (24 hour period orbit with e0) With non-zero eccentricity the satellite track undergoes a periodic motion about the subsatellite point at perigee. -
