text: After readers get into reading, the author provided more great details about Venus. He described planet Venus conditions and why it is so challenging for scientists to study the "Evening Star." According to the author, the "conditions are far more extreme than anything humans encounter on Earth" and "would liquefy many metals." He also gave a background information on how each "previous mission was unmanned" and "no spacecraft survived the landing for more than a few hours." This illustrates how dangerous Venus is. However, the author turn this negativity into a way to learn mistakes. The author says "Maybe this issue explains why not a single spaceship has touched down on Venus," in a way that those factors that may have led to fail previous missions could now be avoided. Mistakes do really teach us lessons.
