Talk:Vanguard TV-3

message: nice. in general, i thought that when we built rockets, their thrust was greater than their weight.
: I assume that's a joke :-)
: All seriousness aside, the second para under "Launch vehicle design" seems to have a lot of errors.  It attributes its source to an article in the July 1957 Popular Mechanics, which I don't have access to, nor do I have other sources; since this is not supposed to be original research, I'll just record my doubts here.  The current article says, "The first stage allows the rocket to rise vertically under the powerful thrust of exploding liquid oxygen, ethyl alcohol, gasoline and silicone oil..."  First, if it explodes then the rocket explodes, which is not the desired effect; rather, it burns in a controlled way.  Second, the list of fuels is clearly wrong; no one would ever fuel a rocket with silicone oil, and I doubt that gasoline would be a wise choice either.  The article on the "Vanguard (rocket)" gives the first stage fuel as kerosene, which is much more likely.  
: The first para of current article also says that all three stages had gimbaled motors.  That is untrue; the third stage used solid fuel, and gimbaled motors were not (and maybe still aren't) useable on solid fueled rockets.  Also, the third stage was spin-stabilized (as noted in the "Vanguard (rocket) article)" and as alluded to in the second para of this article); this is also incompatible with gimbaled motors.

thread_title:  Early discussion 

message: There is a 2-page article in the January 1957 issue of Popular Science that discusses some of the planned instruments for the Vanguard TV3 (including photos).  However, I don't know if this should be cited as a reference as this precedes the launch of the satellite by several months and aspects of the design may have changed.  Interestingly, the article states that the solar powered cell was not intended to provide power, but was instead supposed to reset the memory unit after each orbit.  — Preceding unsigned comment added by Jdmack01 (talk • contribs) 23:49, 3 January 2014 (UTC)
replies: text:   What part of the word "planned" escapes you? The phrase "planned instruments" was and is entirely appropriate.  If you have facts to add, please add them.  98.194.39.86 (talk) 18:06, 17 March 2017 (UTC)
thread_title:  Satellite design section 

message: I realize that the early space race was all about being "better" than the Soviets, but I do remember reading, about ten years ago, a claim that the United States was ready to put a satellite in orbit in 1956, but held off out of concerns that other countries (meaning the Soviets) would object to overflights by American spacecraft.  The supposed idea was to allow the Soviets to go first, so they couldn't later object to American satellites doing the same thing theirs did.  However, the Vanguard failure would appear to give the lie to that claim, because if the U.S. really was ready to go a year earlier, its first attempt after Sputnik would have succeeded.  Does anybody else remember this claim? --Piledhigheranddeeper (talk) 18:18, 6 December 2017 (UTC)
replies: text: The U.S. rocket that was ready to put a satellite in orbit in '56 was Jupiter (rocket).  And, in fact, Explorer 1 succeeded on the first try less than four months after Sputnik.  --Neopeius (talk) 04:14, 23 April 2019 (UTC)

message: The removed information is found (in a much more complete and elegant form as well) in the two cross-references to other Wikipedia articles, more general than a description of this particular launch.  Hope this somewhat novice editor has not overstepped his experience base.  No information added, just removed general, redundant info existing more properly elsewhere.
