RE: "No Mark, you nor any other person has chased me off. I have been on
vacation. I see you are still a back stabber. "

The relevance to recent discussions? Who exactly have I stabbed in the back? I have never pretended to be your friend Barry or to agree with you when I didn't to get you to let your guard down.

RE: "I am waiting until December to make you choke on your words. I have saved all the Mars Nuts posts so that I can remind of what you said."

And what do you think will happen in December? Are you still falsely claiming that finding life on Mars validates Levin even if it is found at another site at a different depth by a different method?

RE: "Until then I really don't want to waste my time answering the same questions I've answered over and over. "

Do you really think yo've answered all the technical challenges to your positions and claims at the links given here? No one with any degree of technical competance would. Reposting the same post already replied to hardly constitutes an astute reply.

Re: Gunn

Exactly what makes you think he is the final authority on this issue? Much work and research has been done since the 1960 agreement he sites. Extremophiles were barely known if at all back then. The clearest evidence you know next to nothing about the potential for manned missions to Mars is here. Yet another place lacking an intelligent reply from you. Lacking anything intelligent to say yet again you tried to change the topic as you no doubt will try to do in response to this post rather than address all your faulty logic documented at these links.

As always any real review of hazards of MSR shoud start at Mars Sample Return: Issues and Recommendations, Washington, DC: National Academy Press, 1997. Additional reputable information is available through the first link.
