| | SPACE.com -- SETI"s Planetary Instruction Kit: Venus and Mars |
 | | Venus surface temperature is about 900 degrees Fahrenheit (482 degrees Celsius), whereas a warm day on Mars is like one of the cooler days in Antarctica. |
 | | As Venus oceans were evaporating, their carbon dioxide was released into the atmosphere, which caused increasing heat, which, in turn, caused increasing evaporation, and so on. |
 | | Mars lets us appreciate our planets continual recycling (we can learn to build structures that withstand earthquakes, and stay away from volcanoes, but the planet still needs them to operate effectively). |
