Bolden Testimony
HOLD FOR RELEASE UNTIL PRESENTED BY WITNESS November 17, 2011 Statement of The Honorable Charles F. Bolden, Jr. Administrator National Aeronautics and Space Administration before the Subcommittee on Science and Space Committee on Commerce, Science and Transportation U. S. Senate Mr. Chairman and Members of the Subcommittee, thank you for the opportunity to appear before you today to discuss the outlook for NASA’s human space flight program. This has been a remarkable year, as we have completed assembling and outfitting of the U.S. On-orbit Segment (USOS) of the International Space Station (ISS), allowing us to focus on full utilization of the Station’s research capabilities; taken key steps in moving forward into the future of exploration beyond Low-Earth Orbit (LEO); celebrated the 50 th anniversary of human spaceflight; and witnessed the successful conclusion of the historic Space Shuttle Program. We are also pleased with the progress our industry partners have made in developing an American capability to transport cargo and eventually astronauts to the ISS, and end the outsourcing of this work to foreign governments. More importantly, this will add a critical level of redundancy for transporting cargo and crew to the ISS. A robust transportation architecture is important to ensuring full utilization of this amazing research facility. Enabling commercial crew and cargo transportation systems in LEO allows NASA to focus on developing its own systems for sending astronauts on missions of exploration beyond LEO. This split between commercial and Government systems allows for a cost effective approach to promote a broad base for human exploration by the United States. -
Observation of Light Curves of Space Objects Hirohisa Kurosaki Japan
Observation of Light Curves of Space Objects Hirohisa Kurosaki Japan Aerospace Exploration Agency Toshifumi Yanagisawa Japan Aerospace Exploration Agency Atsushi Nakajima Japan Aerospace Exploration Agency Abstract Geostationary orbit and low earth orbit have many artificial satellites, and the accidents of these satellites affect every area such as weather forecasts and communications. In the optical observation, the periodical change of the brightness which is caused by the type and the shape of the satellite is seen. In the case of LEO debris, since the movement is fast, it crosses the field of view in several seconds. We used an observation method to get the data of LEO debris. In case of the GEO debris, the rate of motion is slow in comparison with LEO debris. Fixed stars are observed by the same position on the image when the telescope is operated in sidereal tracking mode. Then, space objects are recorded on the image with streaks of light. In this paper, the observation and the detection method of light curve of geostationary orbit debris are discussed. Observing the changes of the operative satellites with some time intervals may help to detect the abnormalities and accidents of them. 1. INTRODUCTION Artificial satellites that have finished their missions and used rockets are called space debris. Most of them are not under any control. The space debris problem must be solved to perform future space development and maintain safety. Many artificial satellites indispensable for human activities circle the earth. If one of these satellites malfunctions, many human activities are impacted. An artificial satellite is monitored to control its trajectory while it is in operation. -
ESA Strategy for Science at the Moon
ESA UNCLASSIFIED - Releasable to the Public ESA Strategy for Science at the Moon ESA UNCLASSIFIED - Releasable to the Public EXECUTIVE SUMMARY A new era of space exploration is beginning, with multiple international and private sector actors engaged and with the Moon as its cornerstone. This renaissance in lunar exploration will offer new opportunities for science across a multitude of disciplines from planetary geology to astronomy and astrobiology whilst preparing the knowledge humanity will need to explore further into the Solar System. Recent missions and new analyses of samples retrieved during Apollo have transformed our understanding of the Moon and the science that can be performed there. We now understand the scientific importance of further exploration of the Moon to understand the origins and evolution of Earth and the cosmic context of life’s emergence on Earth and our future in space. ESA’s priorities for scientific activities at the Moon in the next ten years are: • Analysis of new and diverse samples from the Moon. • Detection and characterisation of polar water ice and other lunar volatiles. • Deployment of geophysical instruments and the build up a global geophysical network. • Identification and characterisation of potential resources for future exploration. • Deployment long wavelength radio astronomy receivers on the lunar far side. • Characterisation of the dynamic dust, charge and plasma environment. • Characterisation of biological sensitivity to the lunar environment.

NASDAQ: SATS 100 Inverness Terrace East Englewood, CO 80112 303.706.4000 | echostar.com EchoStar Annual Report Year Ended December 31, 2012 March 20, 2013 Dear EchoStar Corporation Shareholders; 2012 was a very busy year for EchoStar. One of the most exciting accomplishments for 2012 was the addition of two new satellites to our growing fleet through the successful launches of EchoStar XVI and EchoStar XVII, bringing our total number of owned, leased and managed spacecraft to twenty-two. EchoStar operates the world’s fourth largest commercial geostationary satellite fleet and we continue to solidify our position as a premier global leader in satellite communications and operations. EchoStar ended 2012 with revenue of $3.1 billion, a growth of 13% over 2011. EBITDA in 2012 was $794 million, a growth of 64% over 2011. We generated a healthy $508 million of cash from operating activities in 2012 as a result primarily of the strong net income in 2012 and ended the year with a strong balance sheet with $1.5 billion of cash and marketable securities. EchoStar reached two very important long-term North America goals in 2012 with the market implementation of the HughesNet Gen4 service and the roll-out of the Hopper Whole Home DVR solution for DISH. Both solutions are garnering high praise and rapid adoption by consumers, a glowing testament to the capabilities and ingenuity of the EchoStar team. Additional notable accomplishments for 2012 include the very successful introduction of two new Slingbox retail products, several large enterprise contract renewals and new customers for Hughes data network services around the globe, and above-forecast sales of set-top-box products and video services to our established operator customers. -

Hill, Pietermaritzburg. 6 Fire-as Master and Servant: Its Influence in the Bioclimatic Regions of Trans-Saharan Africa JOHN PHILLIPS* DESPITE MAN's remarkable advances in so many fields of endeavor in Trans-Saharan Africa, there is still much he does not know regarding some of the seemingly simple matters of life and living in the "Dark" Continent: One of these blanks in our knowldege is how the most effectively to thwart fire as an uncontrolled destroyer of vegetation and how best to use it to our own advantage. We know fire as a master, we have learned some thing about fire as a servant-but we still have much to do before we can direct this servant so as to win its most effective service. I review-against a background of the literature and a personal ex perience .of over half a century-some of the matters of prime inter est and significance in the role and the use of fire in Trans-Saharan Africa. These include, inter alia, the sins of the master and the merits of the servant, in a range of bioclimatic regions from the humid for ests, through the various gradations of aridity of the wooded savanna to .the subdesert. In an endeavor to discuss the whole subject objectively and sys tematically, I have dealt with the effects of fire upon vegetation, upon animal associates, upon aerillI factors and upon the complex fac tors of the soil. -
