I believe the author of the article misses the mark on many situations where the expression is used. In the technical domain, when my colleagues or I use the phrase, it's usually in disdainful reference to an inane request or situation where someone can't accomplish or learn a very basic task that they should know due to their lack of effort or attitude. Example 1: "The project manager needs help in formatting worksheets in Excel. It's not rocket science." Example 2: "The client's network admin can't figure out how to open a file with a .zip extension. It's not rocket science."
