Your Reply: HTML is ON UBB Code is ON Smilies Legend	[QUOTE]Originally posted by space1: [B]I have found a "smoking gun," or really a smoking thruster, that I believe places this thruster on Gemini 3 before its flight. In a recent auction I acquired some Gemini reports. One of them is a McDonnell report entitled "SAR - Spacecraft 3 Acceptance Review - Phase I," November 30, 1964. In the Propulsion section, a table lists the Thrust Chamber Assemblies (TCA's) by part number and serial number. Amazingly, the table lists: <BLOCKQUOTE>RCS "B" Ring TCA #4 MAC P/N: 52-52700-217 S/N: 820148 Guarantee Life or Cycles: 136 sec. Accumulated Time or Cycles: 3.0 sec.</BLOCKQUOTE> The serial number matches this artifact. It is apparent that the thruster was later used for tests and was given a new ID tag with new part numbers, and a prefix for the serial number, "NA". But the exact match of the serial number, combined with the evidence presented by the artifact itself. leads me to conclude that this artifact flew on Gemini 3 as TCA #4 on Ring "B". (TCA #4 was a yaw right thruster, mounted at the lower [edit]left of the Reentry Control System section. Ring "B" is the aft set of the two sets of thrusters.)[/B][/QUOTE]
