text: The author mentions, "More importantly, researchers cannot takes samples of rock, gas, or anything else, from a distance." Although this may be a challenge, the author states that many researchers are working on innovations that would allow their machines to last long enough to contribute meaningfully to their knowledge of Venus. In paragraph 7, it states that NASA is working on other approaches to studying Venus, and that it is possible and worthy of doing so. One project is looking back to an old technology called mechanical computers. "By comparison, systems that use mechanical parts can be made more resistant to pressure, heat and other forces." The author does a good job by using details to support that although this is a challenge, they are willing to dive deeper into studying this "Evening Star" known as Venus.
