Question: What profession does Jack Green and Gerard Kuiper have in common?

full_context: Document 1: Barry Voight: Barry Voight (born 1937) is an American geologist, volcanologist, author, and engineer. He is also the brother of actor Jon Voight and songwriter Chip Taylor, and the uncle of actress Angelina Jolie. After completing a five-year intensive dual-degree program at the University of Notre Dame, Voight became a teaching assistant there while pursuing his master's degree. He then studied at Cornell University for a year before transferring to Columbia University, where he earned his Ph.D. in geology in 1965. Voight worked as a professor of geology at several universities, including Pennsylvania State University, where he taught from 1964 until his retirement in 2005; he remains an emeritus professor there. He still conducts research, focusing on rock mechanics, plate tectonics, disaster prevention, and geotechnical engineering.
Document 2: Gerard P. Kuiper Prize: The Gerard P. Kuiper Prize is awarded annually by the Division for Planetary Sciences of the American Astronomical Society for outstanding lifetime achievement in the field of planetary science. The prize is named for Gerard P. Kuiper.
Document 3: Garniss Curtis: Garniss H. Curtis, (born May 27, 1919 – died December 19, 2012) was a professor emeritus of geology at the University of California, Berkeley, geochronologist, volcanologist, geophysicist, and founder of the Berkeley Geochronology Center. In 1960, Curtis and fellow UC Berkeley geophysicist Jack Evernden used potassium-argon dating methods developed by UC Berkeley physicist John Reynolds on minerals found in tephra deposits collected by Evernden to date Mary Leakey's 1959 Olduvai Gorge Bed I hominin "Zinjanthropus" ("Paranthropus boisei") to 1.89 to 1.57 Mya. The great age of the fossil hominid and associated stone tools in the bed pushed back the then accepted age of the Pleistocene another million years, causing a stir in the geology community. The dating of these fossil finds is considered a starting point for the collaboration of paleoanthropology and geochronology.
Document 4: Carl Sagan: Carl Edward Sagan ( ; November 9, 1934 – December 20, 1996) was an American astronomer, cosmologist, astrophysicist, astrobiologist, author, science popularizer, and science communicator in astronomy and other natural sciences. He is best known for his work as a science popularizer and communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space: the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the now accepted hypothesis that the high surface temperatures of Venus can be attributed to and calculated using the greenhouse effect.
Document 5: Gerard Kuiper: Gerard Peter Kuiper ( ; ] ; born Gerrit Pieter Kuiper; December 7, 1905 – December 23, 1973) was a Dutch–American astronomer, planetary scientist, selenographer, author and professor. He is the eponymous namesake of the Kuiper belt. Kuiper is considered by many to be the father of modern planetary science. As professor at the University of Chicago, he was dissertation advisor to Carl Sagan. In 1958, the two worked on the classified military Project A119, the secret Air Force plan to detonate a nuclear warhead on the Moon.
Document 6: Jack Swigert: John Leonard "Jack" Swigert Jr. (August 30, 1931 – December 27, 1982) was an American test pilot, mechanical and aerospace engineer, United States Air Force pilot, and NASA astronaut, one of the 24 people who have flown to the Moon.
Document 7: Jay Greene: Jay H. Greene is a retired NASA engineer. Between 2000 and 2004, he served as Chief Engineer at Johnson Space Center, where his role consisted primarily of advising the Center Director. He worked as a FIDO flight controller during the Apollo Program and a flight director from 1982 to 1986, most notably as ascent flight director during the Challenger accident in 1986. Greene worked for four years as a manager on the International Space Station project and received several awards for his work including the NASA Distinguished Service Medal. After his retirement in 2004 he served as a part-time consultant on the Exploration Systems Architecture Study. NASA Associate Administrator Rex Geveden described him as "a famous technical curmudgeon in the Agency."
Document 8: Compton–Belkovich Thorium Anomaly: The Compton–Belkovich Thorium Anomaly is a hotspot (volcanic complex) on the Moon. It is on the far side of the Moon and was found by a gamma-ray spectrometer in 1998. It is an area of concentrated thorium, a radioactive element. Lunar rock samples from the Apollo missions reveal that most lunar volcanism occurred around 3 to 4 billion years ago, but could have been as recent as 1 billion years ago due to the unknown history of the moon's far side.
Document 9: James E. Atwater: James E. Atwater (born 1946) is a retired North American multidisciplinary physical scientist with training in geophysics, chemistry and biological science. He was awarded the Wright Brothers Medal for his work on microwave powered methods for microbial stabilization and water recovery from solid waste. Atwater served in the United States Marine Corps [1963-1967] prior to attending the University of Utah [1968-1975]. In his early career [1977-1980] Atwater concentrated on methods and instrumentation for identification and quantification of radionuclides associated with uranium exploration and recovery by gamma ray and alpha particle energy spectrometry. Subsequently [1980-1987] he applied radiometric geophysical well logging techniques to the characterization of sandstone, limestone, dolomite and shale core samples. At this time he also refined methods for the determination of porosity and permeability of unconsolidated bitumen and heavy oil bearing sands. Later Atwater’s attention turned to problems of long-term human presence in space, working on regenerable systems for water and air purification, and means for decomposition and stabilization of solid waste materials and recovery of useful resources therefrom. During these years Atwater and colleagues also developed novel sensors and analytical instrumentation for monitoring and control of life support systems. In addition to instrumentation and methods, much of this work entailed the development of novel materials and the characterization of material properties, particularly with respect to magnetic and broadband microwave dielectric phenomena. Recent research includes the study of multiphase immiscible fluid flow in porous media, and the recovery of hydrogen from methane (natural gas) using magnetically stabilized fluidized bed and microwave plasma reactors. Though in retirement, Atwater continues his association with former colleagues, providing theoretical analysis of experimental data, and preparation of materials for publication.
Document 10: Kuiper (disambiguation): Kuiper may also refer to a number of items named after the Dutch-American astronomer Gerard Kuiper:
Document 11: Kuiper (Mercurian crater): Kuiper is a moderate-size crater with a central peak cluster located at on Mercury. It is 60 kilometers in diameter and was named after Gerard Kuiper in 1976. It is one of very few Mercurian craters which are named not after artists, and one of very few cases when the same name is used for 3 craters (there are also Kuiper craters on Mars and on the Moon).
Document 12: Juan Gualterio Roederer: Juan G. Roederer is a professor of physics emeritus at the University of Alaska Fairbanks (UAF). His research fields are space physics, psychoacoustics, science policy and information theory. He conducted pioneering research on solar cosmic rays, on the theory of earth’s radiation belts, neural networks for pitch processing, and currently on the foundations of information theory. He is also an accomplished organist.
Document 13: Kenneth Edgeworth: Kenneth Essex Edgeworth, DSO, MC (26 February 1880 – 10 October 1972) was an Irish astronomer, economist and engineer. He is best known for proposing the existence of a disc of icy bodies beyond the orbit of Neptune in the 1940s in much the same manner as Gerard Kuiper would publish ten years later. Observations later confirmed the existence of what has become known, somewhat controversially, as the Kuiper belt.
Document 14: Donald B. Campbell: Donald B. Campbell is an Australian-born astronomer and Professor of Astronomy at Cornell University. Prior to joining the Cornell faculty he was Director of the Arecibo Observatory in Puerto Rico for seven years. Campbell's research work is in the general area of planetary studies with a concentration on the radio-wavelength-scattering properties of planets, planetary satellites, and small bodies. His work includes studies of Venus, the Moon, the Galilean satellites of Jupiter, Titan, as well as comets and asteroids. Campbell observed near-Earth asteroid 433 Eros, which was the first asteroid detected by the Arecibo Observatory radar system.
Document 15: Jack Green (geologist): Jack Green (18 June 1925 – 5 September 2014) was a geologist and geology professor at California State University Long Beach. His active research included general volcanology and economic geology, as well as mineralogy, lunar protolife, lunar volcanism, water on the moon and astrobiology. His passion for volcanology and the moon was primarily in trying to prove that lunar craters were volcanic and not asteroid impacts, and therefore, there would be water on the moon which would support life. He collaborated with Urey, Shoemaker, Kuiper and others during the "Space Age" heyday, and was active in planning several conferences on remote sensing and the moon.
