text: Scientists want to understand why not one single spaceship has made it to Venus without falling apart. In the passage it says that " Not a single spaceship has touched down on Venus in more than three decades" (Passage 2, Sentance 6). This means that they have not been able to make any spaceship land on Venus. Maybe it could be the 97 percent of carbon dioxide blankets Venus has or the acid in the atmosphere that Venus has. All the spaceships have not survived the landing for more than a few hours. NASA is also working on other stuff so they can approach Venus such as electronics made of silicon carbide and has lasted for three weeks.
