text: NASA is working on a lot of different approaches on how to last a while or have a good landing on Venus. The author tells about the things that we could find out if we could be there for a while. They stress a lot in the passage about it being the hottest planet around and it isn't even the closest to the sun. This is a huge thing holding them back the author says and would melt almost all metal. The author supports this by saying that a submarine that goes very deep in the ocean wouldn't even survive on Venus. The author gives a lot of facts and things to support his claims.
