Copernican Revolution Earth from the center of the universe, set the heavenly bodies in rotation around the Sun, and introduced Earth's daily rotation on its axis. While Copernicus's work sparked the "Copernican Revolution", it did not mark its end. In fact, Copernicus's own system had multiple shortcomings that would have to be amended by later astronomers. Tycho Brahe (1546–1601) was a Danish nobleman who was well known as an astronomer in his time. Further advancement in the understanding of the cosmos would require new, more accurate observations than those that Nicolaus Copernicus relied on and Tycho made great strides in this area.
Lunar and Planetary Institute 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 is 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. The library maintains a weblog called What's New
