text: Secondly, the only support the author has for even traveling to Venus in the first place, is that it is closely related to the planet Earth having features like valleys and mountains. In paragraph 4 he writes "Today, Venus still has some features that are analogous to those on Earth. The planet has a surface of rocky sediment and includes familiar features such as valleys, mountains, and craters." So basically the only reason we should spend the billions of dollars it would take to travel there, is because it is somewhat similar to our planet. The only other support the author has for traveling there is the point that it is the closest planet for planetary visit. Although this might be true, this doesn't rule out the fact how inhospitable and dangerous the planet is.
