Mars 'remains in embryonic state'

Mars formed in record time, growing to its present size in a mere three million years, much quicker than scientists previously thought.

Its rapid formation could explain why the Red Planet is about one tenth the mass of Earth.

The study supports a 20-year-old theory that Mars remained small because it avoided collisions with planetary building material.

The new finding is published in the journal Nature.

In our early Solar System, well before planets had formed, a frisbee-shaped cloud of gas and dust encircled the Sun.

Scientists believe that the planets grew from material pulled together by electrostatic charges - the same force that's behind the "dust bunnies" under your bed.

These proto-planetary dust balls grew and grew until they formed what scientists term "embryo" planets.

These rocky masses were large enough to exert a considerable gravitational force on surrounding material, including other nascent planets.

Dust bunny ping.

Great, now the liberals are gonna want to kill it.

Baloney! Ray Bradbury told me so! ;-)

Mars at home:

"Shhhh... It's da landlord!"

The one thing out there which actually has the power to agglomerate plasma into solid things like planets, stars, galaxies, and strings of galaxies, is the Z-pinch effect associated with cosmic Birkeland currents.

According to the article posted, the frisbee circling the sun went from gas and dust bunnies to become rocky masses. Aren’t there some intervening steps involved, or is this just magic?

Thanks decimon, but I thought Mars was built on chocolate.

Finding Challenges Assumptions of Mars Meteorite, Planet Formation
by Heather Sparks
January 16, 2002

A team of scientists from the University of Amsterdam revealed today in the scientific journal Nature that carbon-based compounds like those inside the Martian asteroid have also been found in two faraway stellar nebulas. Until this discovery, it was thought that all carbonates required liquid-water environments to develop. Now, the carbonates in the meteorite may be inconclusive in proving that liquid water -- and therefore a life-giving environment -- existed on the Red Planet, say the scientists. The carbonates could likely have come from interstellar locales instead.

Thanks decimon.

• Red planet's hue due to meteors, not water -- "There is something of a paradox about Mars," agrees Joshua Bandfield of Arizona State University in Tempe. His team recently showed that the planet has no large deposits of carbonates, which should have formed if giant pools of water had persisted on the surface. Bandfield suggests that liquid water must have occasionally burst out of the ground, carving channels and gullies, but that it quickly froze again in the frigid Martian climate.
