Rather, he was getting us psyched up for that decade-long "peaceful Washington Post competition" with the Soviets to get to the Moon first.

The Planetary Society has tried to bring back the old enthusiasm for space travel by Last spring 's announcement that focusing on a human trip to Mars. But the enthusiasm of those days was unique and NASA would seek Russian help to can't be repeated. That's why there is no equivalent ground swell of public or political redesign and build the space agency's support now for a human trip to Mars.

Uncl as 1992 - 15 Jun. 1993 {Harvard Univ.) 26 p G3/55 0167880 1. INTRODUCTION This report summarizes research accomplished during the third 6-month period of the grant. During the period covered by this report the active personnel included the PI, three graduate students (Darren Leigh, Rik Koda, and Jonathan Weintroub, each averaging a quarter-time research commitment), a Harvard undergraduate (Derrick Bass), and a recent mathematics graduate from Harvard (Nick Shectman). 2. RESEARCH ACCOMPLISHED 2.1 Dual-Horn Antenna Performance As described in the previous progress report, we designed, built, and installed a pair of stacked pyramidal horns. The design was a compromise, with a reduced edge taper of 5.5dB (compared with the canonical 10dB). This was done in order to increase beam lobe overlap, and to permit two horns to fit in the existing radome, which was originally built to hold a single conical horn. We took the unusual step of truncating the corners (see Figure 4 in the previous report), to allow a larger horn aperture within the constraints of a cylindrical radome. Our calculations predicted only a 0.6dB loss of antenna efficiency, and a point-source crossover at the -4dB point; we assumed no feedhorn interactions.

  • Ernst Mayr Taxonomy Book Pdf
    Ernst mayr taxonomy book pdf Continue Ernst Mair is perhaps the most outstanding biologist of the twentieth century, and Systematics and the origin of the species may be one of his greatest and most influential books. This classic study, first published in 1942, helped revolutionize evolutionary biology by proposing a new approach to taxonomic principles and correlated the ideas and conclusions of modern systemicity with those of other life sciences. This book is one of the fundamental documents of Evolutionary Synthesis. This is the book in which Mair for the first time his new concept of species based mainly on biological factors such as interbreeding and reproductive isolation, taking into account ecology, geography and life history. In his new Introduction for This Edition, Mair reflects on the place of this enduring work in the subsequent history of his field.

  • Extraterrestrial Intelligence: an International Petition
    Extraterrestrial Intelligence: An International Petition Carl Sagan (and 68 signatories) – Source: Science, Vol. 218, p. 426, 1982 The human species is now able to communicate with other civilizations in space, if such exist. Using current radioastronomical technology, it is possible for us to receive signals from civilizations no more advanced than we are over a distance of at least many thousands of light years. The cost of a systematic international research effort, using existing radio telescopes, is as low as a few million dollars per year for one or two decades. The program would be more than a million times more thorough than all previous searches, by all nations, put together. The results – whether positive or negative – would have profound implications for our view of our universe and ourselves. We believe such a coordinated search program is well justified on its scientific merits. It will also have important subsidiary benefits for radioastronomy in general. It is a scientific activity that seems likely to garner substantial public support. In addition, because of the growing problem of radiofrequency interfer- ence by civilian and military transmitters, the search program will become more difficult the longer we wait. This is the time to begin. It has been suggested that the apparent absence of a major reworking of the Galaxy by very advanced beings, or the apparent absence of extraterrestrial colonists in the solar system, demonstrates that there are no extraterrestrial intelligent beings anywhere. At the very least, this argument depends on a major extrapolation from the circumstances on Earth, here and now. The radio search, on the other hand, assumes nothing about other civilizations that has not transpired in ours.

Biographical Memoir COPYRIGHT 2009 NATIONAL ACADEMY OF SCIENCES WASHINGTON, D.C. Courtesy MIT Museum PHILIP MORRISON November 7, 1915–April 22, 2005 BY LEO SARTORI AND KOSTA TSIPIS FTER THE EXPLOSIVE lenses were initiated, the nuclear Achain reaction proceeded to its fateful maturity.” These are the words of Philip Morrison (“Phil” to all who knew him) describing the first engineered release of nuclear en- ergy: the plutonium bomb test explosion in the desert near Alamogordo New Mexico on July 16, 1945. The sentence epitomizes the man: a nuclear physicist, a major contribu- tor to the development and testing of the plutonium bomb, deeply concerned about the fateful implications of nuclear weapons for the survival of humanity, and legendary for his mastery of the English language. Philip Morrison, the only son of Moses Morrison and Tillie Rosenbloom, was born on November 7, 1915, in Somerville, New Jersey. He died on April 22, 2005, at age 89, of respiratory failure. When Phil was two the family moved to Pittsburgh to live in his grandparents’ large house. Although his parents were of modest means (his father was a clothing salesman) the Rosenblooms were affluent, having owned a still that was operated under special license during Prohibition and were involved in a steel manufacturing facility outside Pittsburgh.

  • Commission 51: Search for Extraterrestrial Life (Recherche De La Vie Dans L'univers)
    COMMISSION 51: SEARCH FOR EXTRATERRESTRIAL LIFE (RECHERCHE DE LA VIE DANS L'UNIVERS) PRESIDENT: M.D. PAPAGIANNIS VICE PRESIDENTS: F.D. DRAKE and N.S. KARDASHEV ORGANIZING COMMITTEE: R.D. BROWN, P. CONNES, G.D. GATEWOOD, L. GOLDBERG, J. JUGAKU, G. MARX, F. PACINI, M.J. Rbho, V.S. TROITSKY I. INTRODUCTION The possibility that life, primitive or advanced, might exist in other places of the Universe has occupied the minds of scientists and lay-people for thousands of years. It is only in the last 25 years, however, that we have finally begun to search for answers to this profound question using experimental techniques. The goal of Astronomy is to understand the origin and evolution of planets, stars, galaxies and of the Universe as a whole. The appearance of life is an integral part of this whole process and our picture of the Universe will never be complete until we will comprehend also the significance of life in the process of Cosmic Evolution. The modern era in the search for extraterrestrial life, both primitive and advanced, originated in 1959. This was the year that the USSR launched the first Sputnik (October 4, 1959) that opened the new frontier of outer space, and was also the year Giuseppe Cocconi and Philip Morrison [1] published in NATURE their pioneering paper Searching for Interstellar Communications (September 19, 1959). The advent of the space era made possible the exploration of our solar system where we have already searched for primitive life on the Moon (Apollo Missions in 1969) and on Mars (Viking Landers in 1975), and have also landed repeatedly on the infernal surface of Venus (Venera Missions).
