Kepler orbit led to Johannes Kepler working on his celestial mechanics. He later became known as the father of calculus. In 1601, Johannes Kepler acquired the extensive, meticulous observations of the planets made by Tycho Brahe. Kepler would spend the next five years trying to fit the observations of the planet Mars to various curves. In 1609, Kepler published the first two of his three laws of planetary motion. The first law states: More generally, the path of an object undergoing Keplerian motion may also follow a parabola or a hyperbola, which, along with ellipses, belong to a group of curves known
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
