This website is a blog I found through the google search engine.This article informs you about the launch of the Messenger which is trying to find information about Mercury. It says what we know about Mercury and what we would like to know.
Scientists care about studying Mercury because it holds a similar interior to Earth and Mars (Mars is the most similar to Earth out of the planets) even if the core of Mercury is much larger than ours. It especially holds a similar appearance to our moon, along with similar qualities, providing information that our moon and Mercury might have evolved the same way. Its very important to know how planets formed and how similar they are to ours. Scientists are hoping to find out exactly how similar the Mercury is to our familiar planets with the recent launch of the MESSENGER which will take pictures of mercury

I think that the US should look more into space launches. The government is more concerned as to global warming on the earth, when we should consider studying the effects other planets could have on us as well. For instance, it might make a greater impact to know that if we keep using hairspray a black whole would such up the earth or something like that. We are just one small planet in a whole universe! Theres so much we need to know, and theres plenty we already know on earth.
