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 Planetary Data System (PDS) is a distributed data system that NASA uses to archive data collected by Solar System missions. The PDS is an active archive that makes available well documented, peer reviewed planetary data to the research community. [ 1 ]
Theoretical planetology, also known as theoretical planetary science [3] is a branch of planetary sciences that developed in the 20th century. [4] Scientific models supported by laboratory experiments are used to understand the formation, evolution, and internal structure of planets.
A world-sheet is then an embedded surface, that is, an embedded 2-manifold , such that the induced metric has signature (, +) everywhere. Consequently it is possible to locally define coordinates ( τ , σ ) {\displaystyle (\tau ,\sigma )} where τ {\displaystyle \tau } is time-like while σ {\displaystyle \sigma } is space-like .
Simon is a Senior Scientist in the Solar System Exploration Division at NASA's Goddard Space Flight Center, having joined NASA as a civil servant in 2001.She served as the Chief of the Planetary Systems Laboratory from 2008 to 2010 and the Associate Division Director from 2010 to 2013.
He was a research associate at the NASA Ames Research Center. In 1976 he joined the Lunar and Planetary Institute (LPI) as a Staff Scientist and Regional Planetary Image Facility (RPIF) director. In 1984 Schultz was appointed Associate Professor in the Department of Geological Sciences at Brown University and was named Professor in 1994.

Drizzle (or DRIZZLE) is a digital image processing method for the linear reconstruction of undersampled images. The method is normally used for the combination of astronomical images and was originally developed for the Hubble Deep Field observations made by the Hubble Space Telescope.
