text: In looking at the development and changes that Venus has gone through, the planet's past may turn into Earth's future. Though right now the atmosphere contains "almost 97 percent carbon dioxide blankets," and the surface averages over "800 degrees Fahrenheit," it has features found on Earth as well. These include "rocky sediment...valleys, mountains, and craters." Analyzing this enviroment more closely would allow for a deeper understanding of Venus, and may fufill the curiosity of scientists wondering what Earth's "twin" truly is like.
