Voyager Mission Status Bulletin Archives



From 1977 to 1990, the Voyager Mission Status Bulletin saved scientists and
house fanatics knowledgeable concerning the twin Voyager
spacecraft by an intermittently printed e-newsletter that ran to 99
points. A last, 100th challenge was revealed in 1998. Space fan (and pack
rat!) Tom Faber saved his assortment and, in 2010, scanned them and despatched them to The Planetary Society. We are delighted to host these vital historic paperwork right here, and thank Mr. Faber for his persistence 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 web page. Bulletins 1 to
27 seem darkish as a result of they had been printed on coloured paper. The subsequent ones had been printed on white however thinner paper. So far,
Bulletins 1 to 80, protecting the interval from earlier than launch to after
Voyager 2’s Uranus encounter, are on-line; the remainder are coming quickly.Links take you to the PDF paperwork. Below every hyperlink is an inventory of
the part headings inside every e-newsletter and of the photographs, diagrams,
and artworks printed together with the textual content. You may obtain Zipped
collections of the bulletins:Bulletins 1-18 (38 MB): Earth to Jupiter cruise section, August 9, 1977 to April 7, 1978Bulletins 19-42 (62 MB): Voyager 1 Jupiter encounter, April 13, 1978 to May 11, 1979Bulletins 43-47 (18 MB): Voyager 2 Jupiter encounter, June 5 to July 30, 1979Bulletins 48-61 (41 MB): Voyager 1 Saturn encounter, September 12, 1979 to January 14, 1981Bulletins 62-67 (23 MB): Voyager 2 Saturn encounter, June 26 to October 12, 1981Bulletins 68-80 (37 MB): Voyager 2 Uranus encounter, April 10, 1985 to February 25, 1986Bulletins 81-100 (65 MB): Voyager 2 Neptune encounter and past, March 21, 1988 to June 6, 1990 plus July 1, 1998We’re additionally completely satisfied to share a replica of NASA EP-191, “The Voyager Flights to Jupiter and Saturn,”
which was printed by JPL in 1982. EP-191 consists of dozens of big
full-color photographs, presenting one of the best photos and most fascinating
science outcomes from the Jupiter and Saturn encounters. It was scanned
