Voyager Mission Status Bulletins

From 1977 to 1990, the Jet Propulsion Laboratory kept scientists and space enthusiasts informed about the status of the twin Voyager spacecraft through an intermittently printed newsletter that ran to 99 issues. A final, 100th issue was published in 1998. Space fan (and pack rat!) Tom Faber kept his collection and, in 2010, scanned them and sent them to the Planetary Society. We are delighted to host these important historical documents here, and thank Mr. Faber for his patience in scanning them. (Thanks to Betsy Wilson for the 100th.)

Each Mission Status Bulletin is in PDF format, scanned in black and white at 200 DPI, amounting to about 1 Megabyte per page. Bulletins 1 to 27 appear dark because they were printed on colored paper. The subsequent ones were printed on white but thinner paper. So far, Bulletins 1 to 80, covering the period from before launch to after Voyager 2's Uranus encounter, are online; the rest are coming soon.

Links take you to the PDF documents. Below each link is a listing of the section headings within each newsletter and of the photos, diagrams, and artworks printed along with the text. You may also download Zipped collections of the bulletins:

  • Bulletins 1-18 (38 MB): Earth to Jupiter cruise phase, August 9, 1977 to April 7, 1978
  • Bulletins 19-42 (62 MB): Voyager 1 Jupiter encounter, April 13, 1978 to May 11, 1979
  • Bulletins 43-47 (18 MB): Voyager 2 Jupiter encounter, June 5 to July 30, 1979
  • Bulletins 48-61 (41 MB): Voyager 1 Saturn encounter, September 12, 1979 to January 14, 1981
  • Bulletins 62-67 (23 MB): Voyager 2 Saturn encounter, June 26 to October 12, 1981
  • Bulletins 68-80 (37 MB): Voyager 2 Uranus encounter, April 10, 1985 to February 25, 1986
  • Bulletins 81-100 (65 MB): Voyager 2 Neptune encounter and beyond, March 21, 1988 to June 6, 1990 plus July 1, 1998

We're also happy to share a copy of NASA EP-191, "The Voyager Flights to Jupiter and Saturn," which was printed by JPL in 1982. EP-191 includes dozens of huge full-color photos, presenting the best images and most fascinating science results from the Jupiter and Saturn encounters. It was scanned for us by Bill Leung.
