Little Green Men or Just Little Microscopic Organisms?
The question of life on Mars is a puzzle that has plagued many minds
throughout the world. Life on Mars, though, is a reality. When you think of
Martians, you think of little green men who are planning to invade Earth and
destroy all human life, right? Well, some do and some do not. Though believing
that there are little green men on Mars is just a fantasy, or is it? The kind
of life that may have lived there is the kind you would never consider of giving
the name "Martian" to. They are small organisms such as microbes or bacteria.
Proof of this was found in a meteorite containing the fossils of the
microscopic organisms intact. Two highly regarded chemistry professors from
Stanford, Claude Maechling and Richard Zare, dissected three meteorites that
were about 2 to 8 millimeters long and found trace elements of a big mumbo jumbo
wordâ€” polycyclic aromatic hydrocarbons. That pretty much means that there once
was a warmer climate and maybe even lakes or oceans. Life on Mars is now a real
The climate of Mars about 3.8 billion years ago was much similar to the
young Earth. Microbes and bacteria probably sprouted everywhere in the warm and
wet climate. Although now we only see a cold red planet, which was probably due
to a collision of an astroid that would have set back the evolution process of
Mars, causing it to be a harsh planet. A Viking spacecraft which landed on Mars
in 1976 found that the planet was bathed in ultraviolet radiation, "intense
enough so it would probably fry any microbe we know on this planet,"says Jack
Farmer, an Ames researcher who calls himself an "exopaleontologist"â€”a searcher
for fossils on other worlds. The redness of Mars is due to the chemical assault
known as oxidation, which turns iron compounds into rust, and it would surely
kill anything that sticks its head up.
"So why do you still believe that there is life on Mars?" you say. Life
on Mars is not located on the ultraviolet radiation oxidized surface. The
microbes are found below it, probably located in the boiling hot springs, or in
frozen time capsules. Life here on Earth are located in some strange places so
why wouldn't the Martian microbes be found in strange places if they were trying
to survive? Scientists have found bacteria here on Earth that were living
inside rocks where they got all of their nourishment from the rocks and from
some water. Martians probably do the same thing.
The Marsokhod, which is Russian for "Mars Rover"â€” a six-wheeled vehicle
about the size of a golf cart, with an arm for carrying a camera or other
instruments, is planned to launch in 1998. The rover might actually find the
truth that there was once life and that there is still life on Mars.
Who knows, but what if the once ancient microbes or bacteria have
evolved into little green men who are planning to invade Earth and destroy all
human life? What if there was a whole colony of Martians in underground tunnels
all over Mars? How did we evolve? From microscopic microbes, right? They may
have evolved, too. When I read all of this I am reminded by a quote from a
character on Jurassic Park named Ian Malcolm who said, "Life finds a way."
