He opines life's origin is a very important question. Life on Mars with similar RNA & DNA would indicate life could migrate planet to planet via impact debris. Dissimilar life would indicate a second genesis of life. A second genesis would indicate a greater likelihood of life in other star systems. For this reason he advocates robotic exploration of Mars for some time to come. Manned missions could contaminate Mars. He notes asteroids have resources needed in space such as iron and water. Besides resource exploitation, he notes the last 15 years have seen a heightened awareness of impact danger. The articles mentions the Chicxulub impact, Shoemaker-Levy 9's impact with Jupiter and the Tunguska event. The article concludes with Morrison suggesting a Prometheus mission to an asteroid. -- Hop David http://clowder.net/hop/index.html |

So I hope the fundies would support robotic Martian exploration too. -- Hop David http://clowder.net/hop/index.html |
