text: By the end of paragraph 6 the author even writes about his own contradiction: "Venus would need to get up close and personal despite the risks. Or maybe we should think of them as challenges." Such passage shows the reader that even the writer doesn't seem to believe in this mission and that the author needs to keep telling himself that the risks of sending someone to Venus are, in reality, simply "challenges" that need to be overcome. After explaining NASA's work on other approaches to studying Venus, the author actually refers to Venus's surface as chaos, and then concludes the article by claiming that "Our travels on Earth and beyond should not be limited by dangers and doubts but should be expanded to meet the very edges of imagination and innovation" (paragraph 8), a claim that contradicts previous statements made by the author himself.
