Real War of the Worlds?

Earth invades Mars...

Scientist: NASA found life on Mars - and killed it WASHINGTON (AP) -- Two NASA space probes that visited Mars 30 years ago may have found alien microbes on the Red Planet and inadvertently killed them, a scientist is theorizing. The Viking space probes of 1976-77 were looking for the wrong kind of life, so they didn't recognize it, a geology professor at Washington State University said. In the 1970s, the Viking mission found no signs of life. But it was looking for Earth-like life, in which salt water is the internal liquid of living cells. Given the cold dry conditions of Mars, life could have evolved on Mars with the key internal fluid consisting of a mix of water and hydrogen peroxide, said Schulze-Makuch. That's because a water-hydrogen peroxide mix stays liquid at very low temperatures, or -68 degrees Fahrenheit, and doesn't destroy cells when it freezes. It can suck water vapor out of the air. The Viking experiments of the 1970s wouldn't have noticed hydrogen peroxide-based life and, in fact, would have killed it by drowning and overheating the microbes, said Schulze-Makuch.

... those probes weren't that big, considering the size of Mars.

Even if a life-sustaining "puddle" (for want of a better word) had a direct hit, I can't fathom that there weren't or aren't more "puddles" safely remaining. That is, unless the probes introduced some sort of virus for which they had no defense.(Shades of "Independence Day". )

(BTW, Grim.... the link keeps taking me to the CNet forum list page, so I couldn't read the whole article. I think there's a glitch.)

It is truly amazing! I hope I live long enough to see man walk on mars. As a child, I sat in front of my grand dads color TV and watched the first steps onto the moon. I, like so many other kids from the 60s, had space fever and models of Mercury, Gemini, Saturn 5 and moon lander sat on my bed side table. Poor eyesight knocked me out of any chance of being a pilot though, so my dreams adapted.

I am still waiting for the personal anti-grav vehicle or at least a commando cody, sky marshal of the universe**, propulsion system.
