Crash program

"and led to the start of a parallel crash program"

is a strange statement, especially since the actual thing crashed [exploded].

Agreed! The lead paragraph needs work! Sdsds 07:40, 15 March 2007 (UTC)[reply]

Correction

"The Vanguard Satellite Launch Vehicle (the term was invented for the operation SLV models, as opposed to the Test Vehicle TV versions) of the first generation."

This is not a complete English sentence. I'm not sure what idea that sentence was attempting to communicate, or I'd suggest a correction.

Nomenclature

It's my understanding that the Test Vehicle [TV-x] and Satellite Launch Vehicle [SLV-x] designations referred to the launch vehicles, not the respective satellite payloads. So statements like these are inaccurate:

  • "The initial 1.4 kg spherical Vanguard satellites (designated "Test Vehicles" prior to launch)"
  • "the Vanguard satellite TV-4."
  • "TV-4 achieved a stable orbit"

As far as I am aware, the satellites themselves had no designations prior to achieving orbit. So if the payload of TV-3 had reached orbit, it would have been named Vanguard 1.

Sorry, I need to correct myself. Per page 169 of the above referenced pdf, The Vanguard Satellite Launching Vehicle, the satellites did have individual designations. The satellite known as Vanguard I was designated "1958 Beta Two". The satellite known as Vanguard II was designated "1959 Alpha One". And the satellite known as Vanguard III was designated "1959 Eta". Troymc (talk) 04:58, 19 July 2008 (UTC)[reply]

Yes, you make a good point. I would prefer removing the parenthetic comment in the first example you give, and for the other two edit them to read, "the Vanguard satellite launched by TV-4" and "the TV-4 payload achieved a stable orbit." (sdsds - talk) 05:38, 19 July 2008 (UTC)[reply]

Disposition of TV-3

An IP editor User:129.21.57.169 (talk), recently edited the this article, to claim that the NASM holds the original TV-3 satellite, which crashed in December 1957. The information I gave in the article recently, stating it is a replica of Vanguard 1, is based on Vanguard a History, by Constance Green and Milton Lomask, NASA SP-4202, Government Printing Office, Washington D.C., 1970, Chapter 11. Looking at this IP editor's contribution history, I see that there was a contribution providing more information a year or two ago, since lost, suggesting this editor may have personal information. Green & Lomask indicated that TV-3 was fairly badly banged up in the explosion, which is not apparent from the photograph. Nevertheless, if anyone can document facts to the contrary, I am sure we would be happy to know it. Please bring any information here, for discussion and evaluation by other editors. Note that a first-hand memory is not considered enough by Wikipedia reliable source standards; alas. So please do not change the article's information without providing a more reputable source refuting it. I have been in communication in the past with Milton W. Rosen, the Vanguard project manager, who is an old friend (although very old: I do not know if he is even still alive), and he could possibly provide confirming information one way or the other. (Rosen told me something of the history of the Viking 12 reconstruction that is also in the museum.) Thanks, Wwheaton (talk) 03:00, 4 November 2009 (UTC)[reply]

Organization w/r "Vanguard rocket" article?

It seems to me that this article and the corresponding Vanguard rocket article need to be re-organized a bit to put the project history in this and the rocket technical information in the other, with brief sections in each summarizing and cross-referencing the other. Probably Green and Lomask, NASA SP 4202, needs to be the primary reference here, and the Vanguard technical history, "The Vanguard Satellite Launching Vehicle — An Engineering Summary". B. Klawans. April 1960, 212 pages. Martin Company Engineering Report No 11022, should be primary for the rocket article. There would still need to be some overlap, and each article needs to be able to stand alone, but I think it could stand some cleaning up. Wwheaton (talk) 03:13, 4 November 2009 (UTC)[reply]
