I was really disappointed to reach this point and find nothing about the role of mathemeatics in space navigation. I had just been reading up on tensors and thought that would be applicable. I was prepared for there to be no mention of tensors, but to find nothing at all....
[edit] Wikibooks?
Since this article is educational in its intent, I think it'd go better in Wikibooks, no? --朝彦 (Asahiko) 15:19, 29 November 2006 (UTC)
[edit] Frames of reference
This article needs to introduce the notion of a "frame of reference" much earlier. Otherwise the sentence, "Of course, the gravity fields of Earth and Moon also affect its motion, but for short distances, the motion appears perfectly straight" is completely erroneous. (The motion is straight only in a rotating frame of reference. In an inertial frame, a spacecraft slowly approaching the Moon is moving in a circular orbit very similar to the orbit of the Moon.) Understandably the article wants to avoid complex mathematics, but it still needs to be correct! Sdsds 17:32, 27 March 2007 (UTC)
