message: Which satellite is shown on this photo? The photo is dated 1965, therefore it must be after the Echo 1's and Echo 2. --Abdull 14:01, 17 April 2006 (UTC)
replies: text: I asked the same question to the GRIN office at NASA, and after some research they came up with the idea that the image may not show an Echo satellite but more likely a PAGEOS satellite, see  for another image of PAGEOS. The NASA employee also told me the GRIN archive will be updated with new meta information for the image. When this will have happened, the wrong image should be taken off the article. --Abdull 21:05, 4 May 2006 (UTC)

thread_title: What is this?

message: The Summer 2007 Edition of Invention and Technology Volume 23, Number 1 has an article about the Echo Satellite. On page 40 of the article it states the thickeness of the mylar was 0.0005" or 1/2 mil thick (0.0127 mm). This is at odds with the thickness reported on the page. This is a valuable article which has much useful information which could be incorporated into this page. -- Randwulf

thread_title:  which should wikipedia name as "first communication satellite"? 

message: There is strong evidence that both photos show the same satellite. Can this be verified?--217.232.225.68 (talk) 09:16, 28 March 2010 (UTC)

message: The data between this and Echo I are the same.  Moreover, merging will clear up the ambiguity as to Echo I and Echo IA.

message: The orbital parameters seemed a little off on inspection.  Verifying with the wiki on orbital parametershttp://en.wikipedia.org/wiki/Orbital_eccentricity that if  ra = Apoapsis  and rp = Periapsis then eccentricity = (ra-rp) / (ra+rp).  The orbital parameters are in fact as given by a NASA sourcehttp://nssdc.gsfc.nasa.gov/nmc/spacecraftOrbit.do?id=1960-009A (accessed 11 Jan 2015). So I hesitate to make the edit, however, the parameters as given, sourced from NASA and on the Project Echo side boxes, are both inconsistent with themselves. (1684-1524)/(1684+1524) = 0.050 not 0.010 as given both in the source and in the page.   CharcolLion (talk) 22:27, 11 January 2015 (UTC)
