Talk:Grand Tour program

Comments
I labelled my own work "controversial" because I know some people will dissent from my characterization of the Voyager program. Some of my sources describe the program as a scaled-back version of the Grand Tour. Others describe it as an extension of the older Mariner program that incorporated some Grand Tour features. I don't have the background to have a strong opinion on the issue -- I just wanted a Planetary Grand Tour stub so I could write a proper Grand Tour disambiguation page. I'll leave it to people who know the history of space exploration to thrash it out.---Isaac R 20:46, 23 Apr 2005 (UTC)

Looks like there is no controversy. I removed the Controversial tag. --Xyzzyplugh 06:14, 9 February 2006 (UTC)

Category?
How and where can we categorize this thing? Hbdragon88 05:02, 8 May 2006 (UTC)

Map?
Could we get a map of how the planets were set up at the time of the beginning of the Voyager missions. That would help a lot. 71.102.144.27 08:40, 9 March 2007 (UTC)

Solar Grand Tour?
hi, does anyone know about a solar grand tour for all planets in the solar system? I know, that thisis reeeeally difficult and will take long time, but this question is rather a hypothetical one and whether or not this has been reflected about. greets, --Andreas -horn- Hornig (talk) 22:18, 6 July 2010 (UTC)
 * I know nothing specific, but the guy who figured out gravity assist had sequences "a hundred planets long" and said "there was no limit" (BBC's "Voyager - To the final Frontier"). --91.10.62.197 (talk) 11:29, 16 June 2013 (UTC)


 * Check out Interplanetary Transport Network. Essentially, it is possible to get from Sun-Earth's point to almost any place in the solar system with very low energy cost (but very long transfer times). --92.76.197.111 (talk) 15:31, 13 September 2015 (UTC)

What differences between Voyagers and original GT probes
Apart from possible lack of redundancy, how did the Voyager craft (or missions) differ from the proposed GT probes ? - Rod57 (talk) 01:06, 13 August 2014 (UTC)
 * They didn't. Not one whit. Except for Pluto, Voyager 2 did he whole schmeerEricl (talk) 22:27, 17 July 2015 (UTC)

scope of this article
I'm confused. Is this article supposed to be about a specific NASA program, proposed in the '60s and cancelled in December 1971? Or is this article about the concept of a Grand Tour of the planets, fulfilled by Voyager? The text of the article suggests the former, but the image (i.e. diagram of the trajectories of Voyager 1 and 2) suggests the latter. I would suggest that NASA's 2016 "grand tour" poster would be more appropriate for the lead image:            Mathew5000 (talk) 11:12, 29 August 2020 (UTC)

images used in this article
Instead of using File:Voyager Path.svg I would suggest using the image from JPL's 1969 Annual Report (at page 34 of the electronic version, page 32 of the paper version), captioned "Possible trajectory for multiple-planet Grand Tour mission during 1976–82". A similar diagram appears here:. The point is that this article should be illustrated by a diagram showing Pluto, which originally was to be included in the Grand Tour.
