Oral histories in meteorites and planetary science: XII. Gerald J. WasserburgIn this interview, Gerald J. (Jerry) Wasserburg recounts how he entered the Geology Department at the University of Chicago in 1948 but switched to a major in physics, while maintaining links with geology, particularly geochemistry. He earned his Ph.D. in 1954 with a thesis on the new technique of potassium-argon dating under Harold degrees C. Urey and Mark Inghram. After spending a year at Chicago as a post-doctoral research fellow with Urey, he joined the faculty at the California Institute of Technology where he ultimately advanced to the title of John D. MacArthur Professor of Geology and Geophysics. In the early 1960s, Wasserburg sought to achieve unprecedented sensitivity and precision in isotopic measurements by designing and directing the construction of the first digital output with magnet switching and on-line processing computercontrolled mass spectrometer. He promptly named his unique instrument, Lunatic I, and his laboratory, the Lunatic Asylum. Using that instrument and later ones, Wasserburg and his research group identified specific nucleosynthetic processes that produced isotopic anomalies in inclusions found in meteorites; investigated the origin and evolution of planetary bodies from the solar nebula; dated the oldest components in meteorites and in terrestrial and lunar rocks; and studied the oxygen in presolar grains and the astrophysical models of AGB stars. In addition to his labors in science, he served on policy-making committees and worked with other members to seek the highest standards for receiving and processing lunar samples and other planetary materials, and to forestall the elimination of the final three Apollo missions. Wasserburg has received many honors, including several honorary doctorates from universities at home and abroad, and the prestigious Crafoord Prize bestowed on him in 1986 by the Royal Swedish Academy of Sciences. In 1975, the Meteoritical Society awarded him its Leonard Medal and in 1987-1988, he served as President of the Society.

Oral histories in meteorites and planetary science: XIII. Fred L. WhippleBorn in Red Oak, Iowa, in 1906, Fred Lawrence Whipple earned his Ph.D. in astronomy at the University of California at Berkeley in 1931. He immediately accepted a position at the Harvard College Observatory and remained at Harvard throughout his career. In 1950, he was appointed to the Phillips Professorship in the Department of Astronomy, and in 1955, he began serving concurrently as the Director of the Smithsonian Astrophysical Observatory when it moved from Washington, D.C. to Cambridge, Massachusetts. In the 1930s, Whipple established the Harvard Meteor Project in which two cameras, 26 miles apart, simultaneously photographed the same meteors, for which he invariably derived elliptical orbits indicative of their origin within the solar system. In 1950, Whipple introduced his dirty snowball model of comet nuclei, which soon became widely accepted and was fully confirmed in 1986 by close-up images of comet Halley taken by the European Space Agencys Giotto spacecraft. Keenly anticipating the orbiting of satellites during the International Geophysical Year (July 1, 1957-December 31, 1958), Whipple won contracts to build a worldwide network of telescopic cameras for satellite tracking. At least one of the cameras was ready in time to photograph the Soviet Unions Sputnik I satellite in October 1957, and all 12 stations were in operation by midsummer of 1958. For his leadership role in this project, President John Kennedy honored Fred L. Whipple in June 1963 with the Presidents Award for Distinguished Public Service. In the 1960s, Whipple collaborated with astronomers at the University of Arizona to build a new observatory on Mt. Hopkins, 40 miles south of Tucson. Two of the most innovative instruments installed there for astrophysical research were the worlds largest gamma-ray detector and the Multiple-Mirror Telescope. In 1982, the Mt. Hopkins Observatory was rededicated as the Fred Lawrence Whipple Observatory. Although he retired in 1973, Whipple was present at the dedication and until 2003, he continued to actively participate in research projects. At present, he is anticipating the return of the Stardust mission to comet Wild 2, which will bring back to Earth samples of the comet and of interstellar dust. It is scheduled to arrive in 2006, the year of Fred Whipples 100th birthday. Among his many honors, Fred Whipple received the Leonard Medal from the Meteoritical Society in 1970 at its meeting hosted by the Goddard Space Flight Center, in Skyland, Virginia.

Unusual large chromite crystals in the Saint Aubin iron meteoriteIn the Saint Aubin octahedrite, chromite crystals of up to 3 cm occur enclosed in the metal phase. They are twinned along [111] according to the spinel law and display pseudohexagonal shapes in cross-sections. The crystals are homogeneous and exhibit compositions close to pure chromite endmember. Vanadium is the only additional element observed in appreciable amounts of up to 0.73 wt%. Chromite in the Saint Aubin meteorite crystallized from liquids with very low amounts of Cr and O close to the Fe-FeS join as indicated by its composition and phase relations. The growth of large chromite crystals implies stable supersaturated conditions for a long period in the meteorite parent body of Saint Aubin.

Petrography and mineral chemistry of the Reliegos chondriteThe Reliegos meteorite is an L5 ordinary chondrite. The chondrules are embedded in a fine-grained matrix that predominantly consists of olivine and orthopyroxene, with accessory clinopyroxene, troilite, apatite, and a mesostasis of feldspar composition. The metal phase is predominantly kamacite with subordinate taenite and traces of native Cu. The bulk composition of Reliegos compares well with other L5 chondrites, except for a distinctly lower Cr content. A Cr-rich object has been identified, which shows a concentric mineral and chemical zoning and is composed mainly of chromite and plagioclase, with minor amounts of merrillite and Mg, V-rich ilmenite.

Artifacts in Polish collections made of meteoritic ironOnly several artifacts made of meteoritic iron have been found throughout the world. The number of these artifacts is still overstated and has never been verified because museums do not allow specialists to test these objects. Until now, a few objects made of meteoritic iron were discovered in Poland. An axe from Wietrzno-Bobrka and bracelets from Czȩstochowa-Raków are listed as Polish meteorites--the latter ones as Czȩstochowa-Raków I and Czȩstochowa-Raków II. In my opinion, a special meteoritic category should be created for artifacts made of meteorites: meteoritic antiques or manmade artifacts of meteorites and tektite glass. Within such a category, further categorization could be made, based on the material a given meteorite is made of.

Barbianello: An ungrouped nickel-rich iron meteorite found in ItalyAn unusual iron was found in 1960 in Barbianello (northern Italy, Pavia municipality) by a farmer, Clemente Allini, ploughing his fields. Years later, the iron was recognized as a meteorite but not officially classified. Our investigations indicate that Barbianello is a unique nickel-rich ataxite with dark and light regions texturally similar to, but compositionally distinct from, Santa Catharina iron. The light regions are chemically homogeneous, have a Ni content of 27.1 wt%, and a composition similar to irons of group IAB-IIICD. The dark regions are inhomogeneous with Ni ranging from 40 to 58 wt% and oxygen up to 20 wt%. Relics of unoxidized metal and textural relationships indicate that, unlike Santa Catharina, the dark regions result from the oxidation of a metal compositionally distinct from that of light regions.

Spectacular fall of the Kendrapara H5 chondriteAn extremely bright fireball was seen for over 250 km near the eastern coast of India in the evening sky on September 27, 2003. In a rare observation, the fireball was seen by two airline pilots, providing direction of the trail with reasonable accuracy, consistent with ground-based observations. A few fragments of the meteorite were subsequently recovered along the end of the trail in different parts of Kendrapara district (20 degrees 30' N; 86 degrees 26' E) of Orissa. Based on petrography and chemical composition, the meteorite is classified as H5 chondrite. The cosmogenic radionuclides 54Mn, 22Na, 60Co, and 26Al and tracks have been studied in this stony meteorite. Two of the fragments show an unusually high activity of 60Co (~160 dpm/kg) indicating a meteoroid radius of 50-150 cm. Assuming that less than 10% (by weight) of the fragments could be recovered because of difficult terrain, an atmospheric mass ablation of >95% is estimated. Based on the observations of the trail and the estimated mass ablation, orbital parameters of the meteoroid have been calculated. The aphelion is found to lie in the asteroidal belt (1.8-2.4 AU), but the inclination of the orbit is large (22-26 degrees) with respect to the ecliptic. Noble gases have been analysed in two samples of this meteorite. He and Ne are dominantly cosmogenic. Using production rates based on the sample depth derived from 60Co content, 21Ne-based exposure age of 4.50 +/- 0.45 Ma is derived for Kendrapara. One of the samples, known to be more deeply shielded based on high 60Co activity, shows the presence of 80Kr, 82Kr, and 128Xe produced by (n, gamma) reaction on 79Br, 81Br, and 127I, respectively. The (80Kr/82Kr)n ratio of 3.5 +/- 0.9 is consistent with neutrons being mostly thermal. Trapped 84Kr and 132Xe are in the expected range for metamorphic grade H5.

The Bagnone iron meteorite (Tuscany, Italy): History, mineralogy, and chemical classificationBagnone, the largest Italian iron meteorite (48 kg), was found as a single mass at the beginning of the 20th century while ploughing a field close to the Bagnone Castle (Massa Carrara, northern Tuscany). The morphology of the external surface suggests that Bagnone represents a complete individual. It is classified as a medium octahedrite (average bandwidth = 0.96 mm) of the IIIAB chemical group, based on inductively coupled plasma mass spectrometry analyses.
