The natural first option is Mars. For years, NASA has been using rovers to navigate the surface of Mars to find signs of ancient life and water. A couple of years ago, signs of water in a lake were found on Mars by the rover Curiosity, which is a possible indicator of the past existence of microbial life. Ice has also been found on Mars in polar ice caps—which could possibly have liquid water beneath them. Yet, the possible existence of water is not enough to sustain life. The temperature on Mars is significantly lower than the temperature on Earth since it is further from the sun than Earth is. Also, the Mars’ atmosphere is thinner than the Earth’s atmosphere, which would lead to greater levels of UV radiation. Lastly, the distance is also a problem. While we may see Mars as fairly close, it is still around a six-month journey away from Earth with the technology that we currently possess. We are still quite a while away from having Mars as an option for space colonization.

While space colonization may not be necessary for the conceivable future, it is still potentially useful to find Earth-like planets now. Additionally, it provides some possible insight into extraterrestrial life that could be existing on these planets. Who knows what is out there to be found?
