I found this video on www.youtube.com. It was an original BBC news cast. NASA sent this spacecraft to Mars in order to search for life (water). The mission carried a series of scientific devices to analyze the Martian atmosphere, climate, and the composition of its rocks and soil. One of the scientific purposes of the mission was to examine whether Mars could once have supported microbial life forms. The mission was successful and an amazing discovery. Knowing that other planets besides Earth can sustain life is very encouraging for our future.
Although I am indeed excited about scientific discoveries in general and this particular one by NASA, the fact that we aren’t able to protect the planet we live on itself ( with particular reference to the Gulf OIl spill) quickly eliminates that excitement. In my opinion we aren’t ready to even consider if other planets can sustain human life until we at least begin to do a reasonable job of safekeeping earth.
I agree with you, but can we really be the only life forms in the universe. I truly dont think so. But do we really want to find aliens, that is a scary thought.
