Coartney Campbell, 8th grade, Charleston Middle School, Charleston ANSWER: Mars could very well be the first planet to contain life. The outer planets have much more extreme temperatures, than Mars. For example, Venus can be as hot as 900 degrees Fahrenheit. The temperature range for Mars is -199 degrees F to 80 degrees F. There may be evidence of a lower life form on Mars such as bacteria. In fact, a meteorite beleived to have originated on Mars was found on Earth and scientists theorized that it might contain fossils of ancient bacteria. This finding re-opened the issue of life on Mars and the Odyssey spacecraft will be looking for water which is essential to life. If water is found on Mars this would be an excellent site for future exploration.
