CHAPTER 20. LAST LIGHT
236 Several accounts exist. I follow Charlene Anderson, “Voyager’s Last View,” on the Planetary Society’s Web site: www.planetary.org/explor/topics/space_missions/voyager/family_portrait.html, accessed June 23, 2008; and the account given in Carl Sagan, Pale Blue Dot (New York: Ballantine, 1994), pp. 1-7; and the detailed recollection of Candice Hansen, in Swift, Voyager Tales, pp. 323-25. Constance Holden, “Voyager’s Last Light,” Science 248 (1990): 1308, gives the date as the “evening of candice 13 February 1990.” Granted the long process, it spilled over into February 14, which is what has been generally reported.
237 Quote from Sagan, Pale Blue Dot, p. 5.
238 For an interesting account of the competing interests, see Candice Hansen, in Swift, Voyager Tales, p. 324.
239 Quote from Sagan, Pale Blue Dot, p. 5. An interesting UPI story by Rob Stein dates the event to February 13, 1990, a day earlier; see NASA Historical Collection, File 005578.

CHAPTER 21. VOYAGER INTERSTELLAR MISSION

2 On costs: JPL, Voyager Uranus Travel Guide, pp. 105-6. On prospects for shutting down: Andrew Lawler, “NASA Plans to Turn Off Several Satellites,” Science 307 (March 11, 2005): 1541; Tony Reichhardt, “NASA’s Funding Shortfall Means Journey’s End for Voyager Probes,” Nature 434 (March 10, 2005): 125, which lists the costs as $4.2 million annually. The discrepancy seems to derive from the cost of both spacecraft and data analysis.

Vienna, Beyond the Law of the Sea: New Directions for U.S. Oceans Policy (Westport, Conn.: Praeger, 1997), p. 25 for the observation that the concept, and nearly the language, was in American policy, additional fallout from the Antarctic Treaty.

Interestingly, Sagan and Casani were denied copies. One might also note the slightly blasphemous associations possible between the Voyager golden record and Joseph Smith’s golden plates, dug up across the Finger Lakes from Sagan’s Laboratory for Planetary Studies—both metal tablets that record an era and identify its originators, subsequently buried deeply to preserve that memory, a record to be found ages hence, written in a peculiar language surely unintelligible to its eventual finder, save with a special apparatus by which to interpret it, a message ultimately that speaks to the character of its creators. The Voyager golden records and the gold plates of Moroni—the prophet of the space age channeling the prophet of Mormonism? Would an alien intelligence confronted with the association be a lumper or a splitter?

Sources
Voyager: Seeking Newer Worlds in the Third Great Age of Discovery is a study—call it perhaps a meditation—about context. It is not a scholarly reconstruction based on original archives but one that seeks to achieve insights by arranging facts, many of which are common knowledge, and observations, few of which come from unexplored sources. It strives to generate new understanding by emphasizing comparisons, contrasts, and continuities.
Still, some work in archives was useful, and necessary. I have consulted only two such sets of primary documents: the JPL Archives and the NASA Historical Reference Collection at the NASA History Office. Each has guides accessible online. For NASA resources, see also Stephen J. Garber, compiler, Research in NASA History: A Guide to the NASA History Program (Washington, D.C.: NASA, June 1997), and the fine line of monographs the NASA History Office has sponsored.
Most of my research derives from published accounts. These fall into three general areas. Some—quite a few—deal specifically with Voyager, and I am happy to defer to them on matters of design, construction, and operations. Some pertain to exploration generally. Some are specific to the era under examination, particularly its institutions. Those works that I found most pertinent I have listed here. Since exploration is among the most heavily chartered historical literature around, I include only major works that I reviewed for several purposes, or to help establish general concepts. Books or articles consulted for a single fact or purpose are included in the notes where and when they are cited.
