Who made the decision to put the smallpox blanket on the rover? Is captain Bouquet in charge over at NASA?
edit: In all seriousness though, this is a really interesting read. It's something I had not considered. The slightest contamination of the rover could spoil the virgin planet. This is the kind of article that the religious of the world could one day use as an argument that any life/microbes found there were originally brought there by us.
