Dr E. Myles Standish (Erland Myles Standish, Jr) is a mathematical astronomer, former professor at the California Institute of Technology and associated with Jet Propulsion Laboratory. He has published over 900 articles, as listed in Google Scholar and the (Harvard Astronomical Data Service) mostly in the field of solar system dynamics and celestial mechanics.
Dr Standish gained his Ph.D degree at Yale University (thesis, 1968, "Numerical Studies of the Gravitational Problem of N Bodies") and his early professional work at Yale University Observatory concerned celestial mechanics and mathematical astronomy.
He joined the Jet Propulsion Laboratory in the 1970s and continued his work there until his retirement in about 2006.
He is best known for his major role in creating numerically integrated Development Ephemerides of the Jet Propulsion Laboratory which have achieved and retain worldwide usage.
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..

Dr E. Myles Standish (Erland Myles Standish, Jr) is a mathematical astronomer, former professor at the California Institute of Technology and associated with Jet Propulsion Laboratory. He has published over 900 articles, as listed in Google Scholar and the (Harvard Astronomical Data Service) mostly in the field of solar system dynamics and celestial mechanics.
Dr Standish gained his Ph.D degree at Yale University (thesis, 1968, "Numerical Studies of the Gravitational Problem of N Bodies") and his early professional work at Yale University Observatory concerned celestial mechanics and mathematical astronomy.
He joined the Jet Propulsion Laboratory in the 1970s and continued his work there until his retirement in about 2006.
He is best known for his major role in creating numerically integrated Development Ephemerides of the Jet Propulsion Laboratory which have achieved and retain worldwide usage.
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.. Especially with the inclusion of the lunar work of J G Williams and others, improved solar, planetary and lunar ephemerides were developed (in DE102) far enough to have a significant historical as well as current coverage.
Later versions of the Development Ephemerides have been used worldwide. These include: Development Ephemeris DE200, which was officially used in the Astronomical Almanac (and in derived form, also in the Nautical Almanac) as the basis for the ephemerides of sun, moon and planets from 1984 through 2002; and DE405, which has been the basis of the corresponding ephemerides in the Astronomical Almanac and Nautical Almanac from and including 2003, to the present date.
Later examples of the Development Ephemerides supported the navigation of specific NASA planetary space missions with notably precise results.
Dr Standish's work towards the development of the ephemerides took him also into the field of the history of astronomy, including study of the recently-noted occurrence of Neptune in the notes of Galileo, identifying an additional ms observation of Neptune by Galileo (who had regarded it as a background star while studying the satellites of Jupiter), and analyzing its significance for the modern-day ephemerides.
