text: The reasons on why scientists are still discussing about Venus today is because Venus is the only planet that use to look like earth with its rocky terrain and with that Astronmers are fascinated. "If our sister planet is so inhospitable, why are scientists even discussing further visits to its sureface? Astronomers are fascinated by Venus because it may well once have been the most Earth-like planet in our solar system." However it is dangerous and that's the only thing that's stopping NASA from sending a human to Venus because of the harsh conditions, and also Venus has the hottest surface temperature of any planet in our solar system. "These conditions are far more extreme than anything humans encounter on Earth; such an environment would crush even a submarine accustomed to diving to the deepest parts of our oceans and would liquefy many metals." The author supports his claims by providing pros and cons on "The Challenge of Exploring Venus."
