After reading this http://www.space.com/scienceastronom...ne_040824.html article at Space.com, I am starting to feel NASA does deminish the findings of various facts regarding alien life-forms. This down-talk has a reason.
The reason is actually in the article. Toward the end, NASA scientists try to suggest that not only does Methane not mean life, but that we should wait till their "later" missions before we jump to conclusions.
I suppose I find it interesting how they seem to suggest that Volcanic activity is taking place on Mars, and how they want to suggest volcanic activity over organic life-forms. Why? There is as much evidence to suggest volcanoes on Mars as there is that of life. In 1976, the LR experiment tested positive for life. So, why is it such a leap that perhaps due to the findings of Methane in the atmosphere, that it does add to the mounting evidence for microbial life on Mars?
My belief is that NASA does this to ensure continued funding for their programs. They discredit or down-talk every discovery of alien life and drag it out, untill they are late in announcing what we allready know, in order to keep the "need alive" for that next mission. If you don't believe me, look at how they've operated the last 60 years.
So, we have to wait on the issue of life on Mars. Till their next mission. You might as well forget this issue every being solved anytime soon if NASA has anything to do with it.
I am completely biased, I admit it. I even think NASA know's alien civilizations visit our world. They've seen and have acknowleged them outside our space shuttle for years, but have dismissed them. It's also my theory that when the "space tours" start, many people will come back with images or video of strange crafts outside our world. In fact, they will appear everywhere. If that happens, NASA will have hell to pay. Everyone will ask - What has NASA been doing? They've never seen this before? Just think about it. Now, I know a lot of you are going to say - this won't happen. How could we justify the spending of trillions of dollars to send a rover to mars when we have alien life outside our world visitiing us daily? We can't!
