text: However, in order to learn all there is about Venus, you would have to go onto Venus. This is almost an impossible task though. There are many dangers on Venus, including sulfuric acid rain and an atmosphere of nintey seven percent carbon dioxide. Hovering over it would be useless. In paragraph six, it states, "... peering at Venus from a ship orbiting or hovering safely far above the planet can provide only limited insight on ground conditions because most forms of light cannot penetrate the dense atmosphere, rendering standard forms of photography and videography ineffective." This states that by hovering on top of the planet, they can't learn anyting they don't already know.
