INIS Clearinghouse Other IAEA P. 0. Box 100 ^ I L F A-1400, Vienna, Austria Attention Microfiche User, The original document from which this microfiche was made was found to contain some imperfection or imperfections that reduce full comprehension of some of the text despite the good technical quality of the microfiche itself. The imperfections may be: - missing of illegible pages/figures - wrong pagination - poor overall printing quality, etc. We normally refuse to microfiche such a document and request a replacement document (or pages) from the National INIS Centre concerned. However, our experience shows that many months pass before such documents are replaced. Sometimes the Centre is not able to supply a better copy or, in som, cases, the pages that were supposed to be missing correspond to a wrong pagination only* We feel that it is better to proceed with distributing the microfiche made of these documents than to withhold them till the imperfections are removed. If the removals are subsequestly made then replacement microfiche can be issued. In line with this approach then, our specific practice for microfiching documents with imperfections is as follows: 1* A microfiche of an imperfect document will be marked with a special symbol (black circle) on the left of the title. This symbol will appear on all masters and copies of the document (1st fiche and trailer fiches) even if the imperfection is on one fiche of the report only. 2. If imperfection is not too general the reason will "be specified on a sheet such as this, in the space below. 3. The microfiche will be considered as temporary, but sold at the normal price. Replacements, if they can be issued, will be available for purchase at the regular price. 4. A new document will be requested from the supplying Centre. 5. If the Centre can supply the necessary pages/document a new master fiche will be made to permit production of any replace- ment microfiche that may be requested. The original document from which this microfiche has bees prepared has these imperfections: \ j missing pages/figures numbered: • I j wrong pagination I | poor overall printing quality j \ combinations of the above INIS Clearinghouse other IAEA P. 0.

Krastev PROCEEDINGS VARNA, BULGARIA, MAY 6-8,1985 Chairmen of the Organizing Committee - Prof. Zh. Zhelev Secretary - in - charge - L.Kinova FOREWORD , Almost fifty years elapsed from the first publication in the field of activation analysis.During this period activation analysis won a wide recog- nition. Its principal merits: the possibility of simultaneous determination of several elements,the high sensitivity.precision and accuracy of measure- ment, the applicability to different materials,combined with the developement of high resolution semiconductive detectors and multichannel analysers brought it to the state of a preferable analytical method in many' areas of science and technology. In the last few years NAA found a wide application in the Balkan coun- tries with a significant contribution to the technical progress. The common interests in this area are a good premise for collaboration in the. Region. The purpose of the First Balkan Conference on Activation Analysis is to give an opportunity to scientists from this area to exchange information on the state of activation analysis in their countries as well as to create more close contacts.The united efforts of the scientists from Balkan coun- tries will foster the further developement of the activation analysis and, therefore, will enhance the contribution of the atomic energy to peace,health and prosperity in the Region. The Proceeding includes all papers submitted to the Organizing Committee until 1985, March, 30. CONTENTS REVIEW PAPERS Neutron Activation Analysis in Bulgaria D.

    TABLE 1 GEOLOGIC FIELD-TRAINING OF NASA ASTRONAUTS BETWEEN JANUARY 1963 AND NOVEMBER 1972 The following is a year-by-year listing of the astronaut geologic field training trips planned and led by personnel from the U.S. Geological Survey’s Branches of Astrogeology and Surface Planetary Exploration, in collaboration with the Geology Group at the Manned Spacecraft Center, Houston, Texas at the request of NASA between January 1963 and November 1972. Regional geologic experts from the U.S. Geological Survey and other governmental organizations and universities s also played vital roles in these exercises. [The early training (between 1963 and 1967) involved a rather large contingent of astronauts from NASA groups 1, 2, and 3. For another listing of the astronaut geologic training trips and exercises, including all attending and the general purposed of the exercise, the reader is referred to the following website containing a contribution by William Phinney (Phinney, book submitted to NASA/JSC; also http://www.hq.nasa.gov/office/pao/History/alsj/ap-geotrips.pdf).] 1963 16-18 January 1963: Meteor Crater and San Francisco Volcanic Field near Flagstaff, Arizona (9 astronauts). Among the nine astronaut trainees in Flagstaff for that initial astronaut geologic training exercise was Neil Armstrong--who would become the first man to step foot on the Moon during the historic Apollo 11 mission in July 1969! The other astronauts present included Frank Borman (Apollo 8), Charles "Pete" Conrad (Apollo 12), James Lovell (Apollo 8 and the near-tragic Apollo 13), James McDivitt, Elliot See (killed later in a plane crash), Thomas Stafford (Apollo 10), Edward White (later killed in the tragic Apollo 1 fire at Cape Canaveral), and John Young (Apollo 16).

This gives us the tion of the Moon it is essential to investigate the vol- opportunity to investigate the history of small scale canic history of both the lunar near- and farside. While volcanism on the lunar farside. the lunar nearside is dominated by mare volcanism, the farside shows only some isolated mare deposits in the large craters and basins, like the South Pole-Aitken basin or Tsiolkovsky crater [e.g., 1-4]. This big differ- ence in volcanic activity between the near- and farside is of crucial importance for understanding the volcanic evolution of the Moon. The extensive mare volcanism of the lunar nearside has already been studied in great detail by numerous authors [e.g., 4-8] on the basis of Lunar Orbiter and Apollo data. New high-resolution data obtained by the Lunar Reconnaissance Orbiter (LRO) and the SELENE Terrain Camera (TC) now allow us to investigate the lunar farside in great detail. Basaltic volcanism of the lunar nearside was active for almost 3 Ga, lasting from ~3.9-4.0 Ga to ~1.2 Ga before present [5]. In contrast to the nearside, most eruptions of mare deposits on the lunar farside stopped much earlier, ~3.0 Ga ago [9].

  • Appendix I Lunar and Martian Nomenclature
    APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971.

    Lunar craters named in honor of Apollo 8 5 October 2018 The Apollo 8 mission took place from 21 to 27 December 1968. After completing 10 orbits around the Moon on Christmas Eve, broadcasting images back to Earth and giving live television transmissions, the crew returned to Earth and landed in the Pacific Ocean. The Working Group for Planetary System Nomenclature (WGPSN) of the International Astronomical Union, who named the craters, is the authority responsible for the naming of planetary features in our Solar System. The two named craters were previously designated by letters. The Earthrise color photograph taken by astronaut William Anders. It depicts the moment that our shiny blue Earth came back into view as the spacecraft emerged out of the dark from behind the grey and barren Moon. This is arguably the most famous picture taken by Apollo 8. It became iconic and has been credited with starting the environmental movement.Two of the crates seen in this photo have just been named by the Working Group for Planetary System Nomenclature (WGPSN) of the International Astronomical Union.

Still, there are larger craters on the Moon, so why is Copernicus special? The answer is simple: because the crater faces Earth directly, it looks nice and round, exactly the way everyone thinks a crater should look. But what really makes Coper- nicus special is its halo of rays. These wispy streamers stretch outward in every direction. Like the crater itself, they are brightest when the Moon is full. Take a close look at these feather-like Copernicus splashes. When a big object blasts out a crater, the smallest particles travel farthest from the point of impact. This spray of rock then falls in a splash pattern onto the lunar surface. This material looks bright because it’s made up of crushed and broken rock, which Copernicus, King of Craters By Edmund A.

  • The Space Race Documented Through Front Pages of Newspapers from Around North America
    The News Frontier The Space Race documented through front pages of newspapers from around North America Newspapers and patches generously donated to the McAuliffe-Shepard Discovery Center by Jerrid Kenney After the end of World War II, a new battle began: the Cold War. In the mid-20th century, the United States and the Soviet Union were each trying to prove they were better than the other. Both sides wanted to show the superiority of their technology, military, and, by extension, their political systems. Starting in the late 1950s, the battlefront reached space. The United States and the Soviet Union fought to first achieve milestones in space exploration—starting in 1957 with the Soviet Union’s launch of Sputnik I, continuing through the U.S.’s landing astronauts on the Moon in 1969, and ending with a handshake in space between American astronauts and Soviet cosmonauts in 1975. Witness the fight for extraterrestrial might by reading about the United States and the Soviet Union’s major feats of the Space Race, as recorded in American and Canadian newspapers in real time.

  • Klamath National Forest Has Long Been Used for Aeronautical Training for Multiple Governmental Agencies
    ROCKS, BOMBS, AND ASTRONAUTS: AERONAUTICAL TRAINING ON THE KLAMATH NATIONAL FOREST KAITLIN C. HAKANSON NORTHERN CALIFORNIA RESOURCE CENTER KAREN J. BUCHER GOOSENEST RANGER DISTRICT, KLAMATH NATIONAL FOREST Klamath National Forest has long been used for aeronautical training for multiple governmental agencies. In May 1945, the U.S. Navy created the Siskiyou Rocket and Bombing Range. Over 7,000 acres in size, the range featured a wooden target for practice rockets and bombs. With the conclusion of World War II came the decommissioning of the site, where it remained unutilized for decades. In 1991, Butte Valley National Grasslands was established by the U.S. Forest Service to provide range for livestock and wildlife viewing. On the east side of the forest, NASA and the USGS utilized the Medicine Lake Highlands to conduct intensive training for astronauts in the Apollo program starting in 1965. Their main focus was learning to identify and describe geologic features like those on the Moon. Trainees included Roger Chaffee of the ill-fated Apollo 1 mission; lunar module pilots William Anders, Russell L. Schweickart, R. Walter Cunningham, and Alan Bean; and Harrison “Jack” Schmitt, the first geologist in space and one of the last people to walk on the Moon. Innovative and collaborative use of public lands continues to be a hallmark of the Forest Service, with many opportunities still unrealized. Use of the National Forests can be broken down into easily identifiable time periods, each reflecting the social changes our society has experienced through time. The mission of the Forest Service has changed little, however, and is summed up in the current motto “caring for the land and serving people.” Often forgotten in the swift travel of time are the diverse utilizations of federal land by other national, state, and local agencies.

  • Antigravity and Antigravitational Forces
    A n t i g r a One hundred years ago, Albert Einstein came up with a new theory of v i t gravitation. Later he added to his field equations the cosmological y constant which is accountable for the accelerated expansion of the universe. Thus a natural question arises concerning what is the energy source for this expansion. This monograph is about the novel concept of antigravity and antigravitational forces. We present various observational arguments showing the expansion on small cosmological scales. In particular, the Solar system and single galaxies expand at a rate comparable to the Hubble constant. The novelty of our ideas is that traditionally the expansion of the universe according to Edwin Hubble has been assumed to take place only between galaxies. The boldness of our approach is that it points to a weak violation of the law of conservation of energy. We claim that any system of free bodies that interact gravitationally with delays expands on average. We suggest that this is due to gravitational aberration effects resulting from a finite speed of gravity. Our book should be especially useful for scientists who look for the origin of dark matter and dark energy.
