Lunar and Planetary Institute

• 1. Introduction

  ›

  The Lunar and Planetary Institute stands at 3600 Bay Area Boulevard in Houston, Texas, a few miles from what was once the Manned Spacecraft Center. It began with a speech. On the 1st of March 1968, President Lyndon B. Johnson stood before an audience at that same Manned Spacecraft Center and announced the creation of a new kind of scientific institution. He called it the Lunar Science Institute, and he described its purpose in expansive terms: "We will welcome here all who are interested in the sciences of space. We will strengthen the cooperation between NASA and our universities. And we will set new patterns of scientific cooperation which will have profound effects on man's knowledge of his universe."

  What Johnson was describing was not a laboratory in the conventional sense. It was a gathering place, a forum where scientists from universities around the world could come to work alongside NASA's own researchers, to use the center's facilities and photographs, and eventually to study the rock samples that Apollo astronauts would bring back from the Moon. The questions that institution was built to answer ranged from the formation of the Solar System to the geology of distant moons. How those questions came to define a research institute that has now operated for more than five decades is a story worth following.

• 2. From Speech to Institution

  ›

  Johnson's March 1968 announcement did not emerge from nowhere. It was the result of a series of meetings involving NASA, the National Academy of Sciences, and the Universities Research Association, a university consortium that had been founded to run what became Fermilab. Several major universities were also part of those discussions. The Lunar Science Institute was initially operated by the National Academy of Sciences, but that arrangement did not last long.

  On the 11th of December 1969, the Universities Space Research Association, a newly formed consortium known as USRA, took over management of the institute. William W. Rubey became its first director, and under his watch the institute went through the transition to USRA's oversight. A program of visiting university-based scientists was put in place, the first symposium was organized, and the first lecture of the LSI seminar series was delivered. The institute was formally dedicated on the 4th of January 1970, at the former West Mansion on NASA Road 1.

  Rubey served until 1971, followed by Joseph W. Chamberlain, David W. Strangway, James W. Head, and Robert O. Pepin over the next several years. Each director inherited an institution still finding its shape, still tethered closely to lunar science during the final years of the Apollo program.

• 3. A Broader Mandate

  ›

  Thomas R. McGetchin became director in 1977, and he made a decision that would define the institute for generations. Under his leadership, the scope of the Lunar Science Institute expanded beyond the Moon to encompass the study of the entire Solar System. That shift in focus came with a new name: the Lunar and Planetary Institute.

  The change was more than cosmetic. Research topics at the LPI came to include the formation and evolution of the Solar System, the petrology and geochemistry of planetary materials and volatiles, planetary interiors, volcanism, tectonism, impact cratering, and what the institute calls planetary sample science. The geographic range of interest stretched from Mercury to Pluto and the icy moons scattered through the outer Solar System.

  In 1991, under the leadership of David C. Black, the institute moved into a new facility. That building, dedicated in January 1992, brought together several USRA divisions and operations under one roof. It offered more office space, more meeting rooms, expanded computer access, and a larger library. The move represented a physical consolidation of what had already become a wide-ranging scientific enterprise.

• 4. The Conference at the Center

  ›

  Every March, the Houston area hosts the Lunar and Planetary Science Conference, known as the LPSC. The LPI organizes and sponsors it. The five-day meeting draws international specialists in petrology, geochemistry, geophysics, geology, and astronomy to present scientific findings in planetary science.

  The LPSC traces its origins to the Apollo program, when early sessions focused almost entirely on the study of lunar samples. After more than fifty years, it continues to attract planetary scientists and researchers from around the world. That longevity reflects something real about the conference's place in the field: it is one of the few annual venues where the breadth of planetary science comes together under a single roof.

  The LPI also organizes workshops and conferences in both domestic and international locations throughout the year, though the LPSC is the flagship gathering. The institute's role as organizer has helped position Houston as a consistent node in the international planetary science network.

• 5. Building the Next Generation

  ›

  The LPI hosts a Summer Intern Program that places undergraduates in one-on-one research partnerships with scientists at the LPI or at the Johnson Space Center. The goal is to give students direct experience in a working research environment and exposure to careers in planetary science.

  From 2008 through 2013, a separate Lunar Exploration Summer Intern Program ran alongside it, focused specifically on evaluating possible landing sites for robotic and human exploration missions. That program was open to graduate students in geology, planetary science, and related fields, as well as undergraduates who had completed at least fifty semester hours of credit.

  In 2015, a new Exploration Science Summer Intern Program replaced the earlier lunar-focused version, broadening its scope to include both the Moon and near-Earth asteroids. The evolution from a lunar-only program to one covering multiple targets mirrors the trajectory of the institute itself. Among the LPI's outreach efforts is also Planetary ReaCH, a program specifically designed to engage Black and Latinx youth and their families through the expertise of researchers the program calls "Content Heroes."

• 6. Archives, Analysis Groups, and the Library

  ›

  The LPI library holds more than 63,000 cataloged items: books, documents, maps, films, videos, and print and electronic journals and newsletters. Its subject emphasis is planetary science and geology, with some coverage of computer science and remote sensing as a secondary field. The collection was designated a NASA Regional Planetary Image Facility, meaning it holds photographs, maps, and data from planetary missions including Apollo, Lunar Orbiter, Clementine, Mars Pathfinder, Voyager 1, Voyager 2, Magellan, Galileo, and Mars Global Surveyor.

  Since June 2014, nineteen lunar and planetary science books have been digitized and made available online, including titles such as Traces of Catastrophe and Lunar Stratigraphy and Sedimentology. The LPI also published the quarterly newsletter Lunar Science Information Bulletin from March 1974 through July 2023, later renamed the Lunar and Planetary Information Bulletin.

  Beyond the library, the LPI provides support for a range of NASA's community analysis groups. These include the Extraterrestrial Materials Analysis Group, the Lunar Exploration Analysis Group, the Mars Exploration Program Analysis Group, the Venus Exploration Analysis Group, and the Ocean Worlds Working Group, which bridges planetary science and astrobiology. The Small Bodies Assessment Group, also supported by the LPI, covers asteroids, comets, interplanetary dust, small satellites, and trans-Neptunian objects. Walter Kiefer has served as director since 2024, overseeing an institution that now spans all of these functions.
