2014, eighteen lunar and planetary science books, most published by LPI such as Traces of Catastrophe and Lunar Stratigraphy and Sedimentology, have been available online. Education and public outreach The LPI has a long tradition of space science education and public outreach through a number of programs and resources. This effort serves a wide variety of audiences, including K-12 students and educators, undergraduate, graduate, and postgraduate students, and the public in formal and informal venues and on local, regional, and national levels. These programs and resources include the following: Explore! Fun with Science - a program designed to bring space science into libraries and informal learning environments SkyFest - a series of free programs open to all ages that offers night sky viewing opportunities and hands-on activities about four times a year Cosmic Explorations: A Speakers Series - a series of free public lectures presented by international experts in space science (past lectures are made available online at the LPI website) Library The LPI library contains more than 60,000 cataloged books, documents, maps, films and videos, and print and electronic journals and newsletters. The subject emphasis of the collection is planetary science and geology, with limited collection development extending into the secondary support field of computer science remote sensing. There is an ongoing effort to scan and make available to the scientific community and the general public a number of out-of-print planetary science books, NASA documents and images, and related works. (These publications are copyright-free or made available with permission.) This collection was a NASA Regional Planetary Image Facility (RPIF) and includes photographs, maps, and other data from planetary missions including Apollo, Lunar Orbiter, Clementine, Mars Pathfinder, Voyager 1, Voyager 2, Magellan, Galileo, and Mars Global Surveyor.
