text: scientists want to further understand Venus so they're trying to make technolgy that can with stand the 800 degrees Fahrenheit, atmospheric pressure that is 90 times greater than earths, an "atmosphere of 97% carbon dioxide," "and clouds of highly corrosive sulfuric acid." So scientists and the author think this is a worthy pursit because trying to further understand Venus (Earth's twin) is the closest planet to Earth in terms of density and size." Venus also has simular weather patterens and ground structures to Earth it has volcanoes that erupt, earthquakes, lightning, a surface of rocky sediment, valleys, mountians, and craters. It is believed that "Venus was probably covered largely with oceans and could have supported various forms of life."
