text: Venus is like Earth in a lot of ways. It is believed to have had water and life on it before, and it even has physical features like Earth. It also is almost the same size and density as Earth. Scientists want to explore this because it is there first option for space travel. Earth is sometimes closer to Venus than it is to Mars. They want to find out the best way to make it hospitable for people to live there. They have sent unmanned probes there to scout out the territory and to find samples and more evidence that could help them. However, the probes don't last long because of the harsh atmosphere.
