The article says the term was first used in science fiction. As there are no citations, there is no evidence it has been used anywhere else in real-world spaceflight. JustinTime55 (talk) 15:56, 30 November 2011 (UTC)[reply]
The term is used very frequently by orbital dynamicists (also known as orbital mechanics engineers), and quite a bit of astrogation technique is taught at US grad schools, especially UT Austin and CU Boulder. One of the very standard and widely used pieces of astrogation software used by both government agencies and commercial companies (and students) is STK Astrogator from AGI software. You can look it up on the web. Cheers. N2e (talk) 21:33, 23 May 2012 (UTC)[reply]
Oxford dictionary specifically says "in science fiction" http://www.oxforddictionaries.com/definition/english/astrogation . Google books and google scholar only seem to have science fiction related hits, or very speculative articles. A software tool with "Astrogator" in its name isn't sufficient. I'm calling this a science fiction term in the absence of any evidence otherwise. Adpete (talk) 01:00, 4 November 2015 (UTC)[reply]
