BarryKirk - 20/1/2007 9:44 AMThanks for the info.So that leaves the question about what the anomoly is. Of course, Elon himself may not understand the cause of the anomoy himself. That is probably an object of intense research right now at Space X.
edkyle99 - 20/1/2007 7:42 PMThe SpaceX update made the problem fairly clear - "an anomaly with the thrust vector control (TVC) pitch actuator on the second stage". There would have been a point in the countdown when the engine would have been swiveled briefly to test it. It must not have passed the test. The problem is said to be associated with one of the two TVC actuators that move the engine. According to the SpaceX web page: "thrust vector control is provided by electro-mechanical actuators on the engine dome for pitch and yaw."
