Useful Planetary Data

2018

How did life on Earth begin? How common is it elsewhere in the Universe? Written and edited by planetary scientists and astrobiologists, this undergraduate-level textbook provides an introduction to the origin and nature of life, the habitable environments in our solar system and the techniques most successfully used for discovery and characterisation of exoplanets. This third edition has been thoroughly revised to embrace the latest developments in this field. Updated topics include the origins of water on Earth, the exploration of habitable environments on Mars, Europa and Enceladus, and the burgeoning discoveries in exoplanetary systems. Ideal for introductory courses on the subject, the textbook is also well-suited for self-study. It highlights important concepts and techniques in boxed summaries, with questions and exercises throughout the text, with full solutions provided. Online resources, hosted at www.cambridge.org/features/planets, include selected figures from the book, self-assessment questions and sample tutor assignments.

The planetary data system

R. E. Arvidson, Sandra Dueck · Remote Sensing Reviews · 1994

Abstract The Planetary Data System (PDS) is a distributed, discipline‐oriented entity with the following objectives: (a) assemble, publish, and distribute peer‐reviewed, documented planetary datasets; (b) work with planetary missions to ensure that datasets will be PDS‐compatible and will be delivered to the PDS on predetermined schedules; (c) develop and maintain standards and tools for assembly and documentation of datasets; and (d) provide expert assistance to the planetary community on data ordering functions, analysis techniques, and preparation of PDS‐compatible datasets. To implement these objectives the PDS is divided into several nodes. The Central Node is responsible for managing the PDS, interfaces with missions, developing standards, and technology utilization. The Navigation and Ancillary Information Facility concentrates on planet, spacecraft, and instrument position and orientation information, and the Imaging Node handles large, raw‐image archives. The PDS also includes a suite of discipline‐oriented nodes—Planetary Atmospheres, Geosciences, Planetary Plasma Interactions, Small Bodies, and Rings. The PDS has interacted with a number of planetary missions and has also sponsored the preservation of a number of older datasets. The involvement of the planetary community in defining the structure of the PDS and in implementing the operational system has been fundamental to the success of this distributed system. Specific examples described in the paper to illustrate PDS archiving are the production and distribution of Magellan datasets and the archive compiled from the Geologic Remote Sensing Field Experiment.

The Planetary Data System

Steven W. Lee · Reviews of Geophysics · 1991

NASA has sponsored the development of the Planetary Data System (PDS) in order to preserve the scientific returns from past and future planetary missions and to make those data readily accessible in a well‐documented form. The PDS encompasses all planetary data, but also provides a distributed, discipline‐oriented architecture to best serve the needs of the diverse planetary sciences user‐community. It is the intention of the PDS to ease and promote the analysis of planetary data through the development and application of data and documentation standards, basic analysis tools, and technology.

Earth-Based Planetary Data

nasa · 2019

NASA sponsors Earth-based planetary astronomy to provide data needed for: planning future missions; supporting missions already in progress; and enhanching the scientific analysis of data returned by past missions. Such data complement spacecraft data by providing observational coverage of important planetary phenomena at epochs before and after spacecraft encounters, with time scales longer than a spacecraft encounter, and at wavelengths and spectral resolutions not covered by spacecraft instruments. Earth-based planetary data are defined here as: observations made with ground based telescopes, balloon-borne instruments, rocket-borne instruments, and Earth-orbiting spacecraft. Data in the last category differ somewhat in nature and availability from the other three. In all categories, planetary data are only a subset of the total astronomical observations on record. As a result part of the task is to identify and extract (or separately catalog) those observations which are planetary. The data cover wavelengths in the ultraviolet, the visual, and the infrared. The instrumental techniques addressed are: imaging, polarimetry, photometry, spectrophotometry, and spectroscopy.

The Planetary Data System data model

J. Steven Hughes, Y.P. Li · 2002

The authors describe the object-based data model in use by the Planetary Data System (PDS). This model, based on the Object Description Language (ODL) and consisting of keyword/value statements, is both human- and computer-readable and has been used to label large volumes of science data being prepared for CD-ROM archive volumes. The use of ODL for defining the objects that compose the PDS model, as well as its use in the actual labeling, has shown it to be a powerful yet simple tool for supporting the science-data archive process.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

International Planetary Data Alliance (IPDA) IPDA Planetary Access Protocol

Editor(s) Jesús Salgado, Pedro Osuna, Pedro Osuna (esa/psa et al. · 2016

and the IPDA technical expert group members 1 This specification defines a protocol for the retrieval of distributed planetary data. The interface is meant to be reasonably simple to implement by service providers. The basic summarized functionality of the protocol is as follows: a query defining a certain restriction on the available data is used as a first step to query for candidate data. The service returns a list of candidate hits formatted as a VOTable. For each candidate hit an access reference URL may be used to retrieve the real data. Data may be returned in a variety of formats. This specification describes the “simple ” way to access the data through an HTTP protocol. Other types of more complex access, eventually using SQL-like language and more complex transports as SOAP, will be worked on within the IPDA technical experts group.

Data-Spheres of Planetary Urbanization

Grga Bašić, Neil Brenner, Mariano Gomez-Luque · 2025

How can we map the urbanization of the planet in an era of climate breakdown? The Urban Theory Lab's Data-Spheres of Planetary Urbanization confronts this question by assembling a series of experimental visualizations of the worldwide urban fabric. This book reverses the mainstream, city centric perspective on urbanization, showing, instead, that the world of contemporary urbanization encompasses much of the planet, including apparently remote areas, wildlands, and oceans. Cities are not only producers of value, but entropic black holes that consume surpluses produced elsewhere and project waste back into the planetary biosphere. Non-city spaces are, correspondingly, the metabolic bases of planetary urbanization. With a foreword by Jason W. Moore, an afterword by Alexander Arroyo, and contributions by Martín Arboleda, Danika Cooper, Kian Goh, Julie Michelle Klinger, Roi Salgueiro Barrio, and Hashim Sarkis Shows the impact of planetary urbanization in 500 beautiful and revealing spatial data visualizations Highlights the importance of operational landscapes beyond the city Assembles theoretical and methodological texts by the Urban Theory Lab as well as critical commentaries

The semantic planetary data system

J. Steven Hughes, Daniel Crichton, Seán Kelly et al. · 2005

Abstract. The Planetary Data System (PDS) data model was developed in the late 1980’s and models the entities and relationships of interest within the Planetary Science Community. It was developed to both prescribe the metadata to be collected for the planetary science data archive and to design the PDS Catalog, a high level inventory of the data holdings in the archive. This catalog, an inventory of over one thousand data sets and related entities, represents a planetary science ontology. Since the advent of the Web, most of the information on the Web has been designed for human consumption using HTML and the

Northeast Regional Planetary Data Center

P. H. Schultz, Stephen Graham Saunders · NASA Technical Reports Server (NASA) · 2005

In 1980, the Northeast Planetary Data Center (NEPDC) was established with Tim Mutch as its Director. The Center was originally located in the Sciences Library due to space limitations but moved to the Lincoln Field Building in 1983 where it could serve the Planetary Group and outside visitors more effectively. In 1984 Dr. Peter Schultz moved to Brown University and became its Director after serving in a similar capacity at the Lunar and Planetary Institute since 1976. Debbie Glavin has served as the Data Center Coordinator since 1982. Initially the NEPDC was build around Tim Mutch's research collection of Lunar Orbiter and Mariner 9 images with only partial sets of Apollo and Viking materials. Its collection was broadened and deepened as the Director (PHS) searched for materials to fill in gaps. Two important acquisitions included the transfer of a Viking collection from a previous PI in Tucson and the donation of surplused lunar materials (Apollo) from the USGS/Menlo Park prior to its building being torn down. Later additions included the pipeline of distributed materials such as the Viking photomosaic series and certain Magellan products. Not all materials sent to Brown, however, found their way to the Data Center, e.g., Voyager prints and negatives. In addition to the NEPDC, the planetary research collection is separately maintained in conjunction with past and ongoing mission activities. These materials (e.g., Viking, Magellan, Galileo, MGS mission products) are housed elsewhere and maintained independently from the NEPDC. They are unavailable to other researchers, educators, and general public. Consequently, the NEPDC represents the only generally accessible reference collection for use by researchers, students, faculty, educators, and general public in the Northeast corridor.
