text: In paragraph five, the author talks about how NASA is trying to build a spacecraft that can withstand Venus's envirmonet. He/she explains in paragraph 2 that no spacecraft that has been sent to Venus has ever survived the landing for more than a few hours. The author talks about how NASA wants to build a blimp that will hover 30 miles above the surface of Venus so that is can avoid the harsh conditions on the surface, although right after this, he/she states that even 30 miles up off the surface, Venus is still going to be around 170 degrees Farenheit. The extremly high air pressure, heat, harsh storms, etc will all have to be concidered when trying to build a spacecraft that will be able to survive on Venus. Once again, these paragraphs are not explainging much good that is coming out of a manned trip to Venus.
