text: The author begins by talking about Venus' history as a planet. He referrs to it as Earth's "twin" becasue of the planet's simmularities. The author says, "Long ago, Venus was probably covered largely with oceans and could have supported various forms of life, just like Earth." This sentence helps develope the authors point of how Earth and Venus are twins. Before this though, the author described how dangerous Venus has become and how it has almost become impossible for scientists to send a robot to the planet. Although, the author does say that it wouldn't be impossible to live there. The author also says that if a vehicle hovered about thirty or so miles above the suface, temperatures would be hot, but the pressure would be the accuivalent to sea level on Earth. After this, the author includes that solar power would be plentiful, and radiation would not exceed Earth's levels. After this, the author moves on to show what scientists are doing to study the planet so that maybe one day we can live there, or atleast visit for a longer period of time. Scientists are studying older technologies that do not use electricity, but can calculate number and withstand harsh conditions. One example the author uses of this is the mechanical computer. After this, the author goes into detail about how it was used in world war two and how with the right metal, it could possibly withstand Venus' conditions. To finish off the paragraph, the author talks about how modern computer that use electricity are often more delicate, to show why the scientists are using this older technology. The author then wraps the imformation that has been said all together by saying, "Our travels on Earth and beyond should not be limited by danger and doubts, but should be expanded to meet the very edges of imagination and innovation."
