GP-B in a Nutshell

"GP-B in a Nutshell" is a two-page PDF document that provides a concise overview of the program, briefly summarizing its history, the flight mission and experiment, the science and technology, spinoffs, and program status as of mid-2008.

Executive Summary, Preface & Spacecraft Info

Preface, Executive Summary & Quick Facts (from GP-B Final Report to NASA)

This 28-page document covers the same content as the GP-B in a Nutshell overview above, but in much greater detail. This document was excerpted and assembled from the 630-page GP-B Post-Flight Analysis, Final Report to NASA.

GP-B/NASA Fact Sheet

GP-B/NASA Fact Sheet

This is a standard NASA Fact Sheet summarizing the GP-B experiment and mission. The original four-page version was prepared prior to launch and included in a GP-B Press Kit package. In 2005, while the GP-B flight mission was well underway, this fact sheet was updated and augmented to six pages. This document, while accurate, is less up-to-date than either the Nutshell or Executive Summary described above.

 

GP-B Electronic Press Kit

GP-B Pre-Launch Press Kit

This 68-page electronic press kit was developed for distribution to the press and media during the GP-B spacecraft launch in April 2004. As of 2008, the science and technology sections of this press kit are still valid, but other parts, such as media contacts and media services information are now out of date and/or invalid.

News Releases & News Stories

Because GP-B has been a joint collaboration between Stanford University, NASA and Lockheed Martin Missiles & Space Company, at various milestones in the program's history, each of these institutions has issued its own news releases and/or news stories. The links to such releases and stories below are thus organized by institution and by date in reverse chronological order.

Selected Newspaper, Magazine and Television Feature Stories

Following are links to selected feature stories about GP-B that have appeared in major newspapers and magazines over the years. In those cases where we have been granted permission to reproduce a story, the link will go to a local PDF or Flash video file that you can view or download. All other links go to the respective Web sites of the newspaper, magazine or television network in which the story was published. Note that over time, some of these links may become invalid due to Web site revisions.

GP-B Photos & Artwork

The Image Gallery on this Web site contains a comprehensive collection of GP-B photos and artwork. The images have been categorized (e.g. gyroscope photos, spacecraft photos, facilities, photos, drawings & illustrations, etc.). The images for each category were then grouped into albums. Many of the photos and drawing are captioned. All of the photos and images in the GP-B Image Gallery may be downloaded at no charge and used in news and media stories, publications and for educational purposes.

All of of the photos and images in the gallery are displayed in low-resolution (72 dots-per-inch) format, optimized for Web viewing. However, most—but not all—of the images were originally created in high-resolution (200-600 dots-per-inch) format, and in these cases, you can download the full-resolution version by clicking the disk icon button in the lower right corner of the image display window.
