It seems to me the largest drawback to a manned Mars mission is the manned part. From the point of view of an outsider looking in, the negative and deleterious effects of zero or low G's on the body needs to be addressed. Loss of vision,loss of muscle, and loss of bone density are only a few of the problems the passengers of such a mission would have to deal with. To my knowledge, the only way to produce some king of gravity would be to accelerate the craft at 1g to the planet and then decelerate at 1g as they arrive--cool idea but no such engine exists today! The other alternative is to have a rotating ring around the ship--hmm, how do you stop the inside ship from rotating? Of course , just a big honkin rotating ring would make sense to make the journey in. The last two options would require assembly in space! The life support systems alone are a huge feat and have to be 100% functional 100% of the time!While exercise curbs some of the negative affects of low g, it does not cure the problem.While there is a coolness factor to a man walking on Mars, to me it just does not make sense!With current technologies we can use robotics to do the job for a hell of a lot less costs and net the same results. Am I off base with my thinking? What are your thoughts on the matter. ---H
