[QUOTE="Nick Martin, post: 5470588, member: 592019"] Thanks for some great answers [I]"It would be instantly vaporized. But the odds of there being something in the way are quite small."[/I] Yes but what would happen to the planet it hit? And the odds are that it will hit something eventually before the end of the universe! "think the laser beam would be larger than the solar system when it arrives back here. So no need for fine pointing, and we would just be picking up a small part of the signal." [I]Sorry I didn't make this very clear - What I meant in the question was suppose the laser beam propelling the craft starts to miss its target - there is no feedback to the laser team for minutes/houors/days/years depending on how far it has travelled, and when they make the next adjustment it might have veered off again.
