Geoffrey A. Landis The new solar system The Solar System: Recent Exploration Results The solar system has been visited by space probes, ranging from the Mariner Mercury-Venus mission exploring inward toward the sun, and continuing through the Voyager probes out into interstellar space and (on its way now) the New Horizons probe to Pluto and the Kuiper belt. This talk examines what we know of the planets of the solar system from probes, and talks about where we will go from here. -- Geoffrey A. Landis NASA John Glenn Research Center, Cleveland OH https://ntrs.nasa.gov/search.jsp?R=20070010742 2018-05-08T11:58:23+00:00Z
