Planetary geology, alternatively known as astrogeology or exogeology, is a planetary science discipline concerned with the geology of celestial bodies such as planets and their moons, asteroids, comets, and meteorites. Although the geo- prefix typically indicates topics of or relating to Earth, planetary geology is named as such for historical and convenience reasons; due to the types of investigations involved, it is closely linked with Earth-based geology. These investigations are centered around the composition, structure, processes, and history of a celestial body.
Kappa Kappa Gamma (ΚΚΓ), also known simply as Kappa or KKG, is a collegiate sorority founded at Monmouth College in Monmouth, Illinois, United States.
Mignon Talbot was an American paleontologist. Talbot recovered and named the only known fossils of the dinosaur Podokesaurus holyokensis, which were found near Mount Holyoke College in 1910, and published a scientific description of the specimen in 1911. In 1909 she became the first woman elected to be a member of the Paleontological Society. In the state of New York, she contributed to the Helderbergian crinoids and studied the faunas of Stafford limestone.
Women in geology concerns the history and contributions of women to the field of geology. There has been a long history of women in the field, but they have tended to be under-represented. In the era before the eighteenth century, science and geological science had not been as formalized as they would become later. Hence early geologists tended to be informal observers and collectors, whether they were male or female. Notable examples of this period include Hildegard of Bingen who wrote works concerning stones and Barbara Uthmann who supervised her husband's mining operations after his death. Mrs. Uthmann was also a relative of Georg Agricola. In addition to these names varied aristocratic women had scientific collections of rocks or minerals.
Alpha Kappa Nu (ΑΚΝ) was one of the first documented African-American collegiate fraternal organizations in the United States. Formed in 1903 at Indiana University and lasting until around 1905, it had a membership of 10, which included all the colored students at the school. A second chapter was set to be established at Wilberforce University. Wilberforce University was where the fraternity Gamma Phi was founded in 1905.
David Stewart McKay was chief scientist for astrobiology at the Johnson Space Center. During the Apollo program, McKay provided geology training to the first men to walk on the Moon in the late 1960s. McKay was the first author of a scientific paper postulating past life on Mars on the basis of evidence in Martian meteorite ALH 84001, which had been found in Antarctica. This paper has become one of the most heavily cited papers in planetary science. The NASA Astrobiology Institute was founded partially as a result of community interest in this paper and related topics. He was a native of Titusville, Pennsylvania.
Catharine Anastasia Conley was NASA's 6th Planetary Protection Officer from 2006 through 2018.

Richard Owen was a Scottish-born geologist, natural scientist, educator, and American military officer who arrived in the United States in 1828 and settled at New Harmony, Indiana. Owen, who was trained as a natural scientist and physician, served as an infantry officer in the U.S. Army during the Mexican–American War and the American Civil War. After the Civil War, Owen taught at Indiana University for fifteen years (1864–79) and chaired its natural science department. While retaining his faculty position at IU, Owen also served as Purdue University's first president (1872–74). During the interwar years, Owen taught natural science at the Western Military Institute in Kentucky and after its merger with the University of Nashville in Tennessee. In addition, Owen assisted his brother, David Dale Owen, with early geological studies of the Northwest Territory. In 1860 Richard Owen succeeded his brother to become Indiana's second state geologist. His research interests included geology, meteorology, terrestrial magnetism, and seismology. Owen authored scientific works that included geological surveys of several U.S. states.

Kennda Lian Lynch is an American astrobiologist and geomicrobiologist who studies polyextremophiles. She has primarily been affiliated with NASA. She identifies environments on Earth with characteristics that may be similar to environments on other planets, and creates models that help identify characteristics that would indicate an environment might host life. Lynch also identifies what biosignatures might look like on other planets. Much of Lynch's research on analog environments has taken place in the Pilot Valley Basin in the Great Salt Desert of northwestern Utah, U.S. Her work in that paleolake basin informed the landing location of NASA's Perseverance Rover mission—at another paleolake basin called Jezero Crater. Jim Greene, Chief Scientist at NASA, called Lynch "a perfect expert to be involved in the Perseverance rover." Helping to select the proper landing site for NASA's first crewed mission to Mars in 2035 is another of Lynch's projects. Lynch has appeared in multiple television series, as well as The New York Times, Nature, Scientific American, and Popular Science. Cell Press designated Lynch one of the most inspiring Black scientists in the United States.
