NASA Ames Research Center, SETI Institute, NASA Lunar Science Institute, Solar System Exploration Research Virtual Institute David Morrison (born June 26, 1940) is an American astronomer , a senior scientist at the Solar System Exploration Research Virtual Institute , at NASA Ames Research Center in Mountain View, California .
Theoretical planetologists also use numerical models to understand how the Solar System planets were formed and develop in the future, their thermal evolution, their tectonics, how magnetic fields are formed in planetary interiors, how convection processes work in the cores and mantles of terrestrial planets and in the interiors of gas giants ...
William Kenneth Hartmann (born June 6, 1939) is an American planetary scientist, artist, author, and writer.He was the first to convince the scientific mainstream that the Earth had once been hit by a planet sized body (), creating both the Moon and the Earth's 23.5° tilt.
An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; however, since accurate scaling is often not practical due to the actual large ratio differences, it ...
David H. Grinspoon (born 1959) is an American astrobiologist.He is the Senior Scientist for Astrobiology Strategy at NASA [1] and was the former inaugural Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology for 2012–2013.
Standish worked on the Jet Propulsion Laboratory Development Ephemeris.. Early versions refined the accuracy of these fundamental astronomical data-sets by including many recent and accurate observational data, new types of data, using improved data processing methods, including refined equations of motion which more accurately described the actual physics of the solar system.

The Family Portrait of the Solar System taken by Voyager 1. The Family Portrait, or sometimes Portrait of the Planets, is an image of the Solar System acquired by Voyager 1 on February 14, 1990, from a distance of approximately 6 billion km (40 AU; 3.7 billion mi) from Earth. It features individual frames of six planets and a partial background ...
Bruce Leonard Cathie (11 February 1930 – 2 June 2013) was a New Zealand airline pilot who wrote seven books related to flying saucers and a "World energy grid".. His central thesis was that he could use mathematics to describe a grid-like pattern on Earth (i.e. the Electro-dynamic field on Earth) that powers flying saucers and controls the dates and places where nuclear bombs can function ...
