Rock of Ages: Scientists Determine Mars Once Had Mild Surface Temperature

This is a very cool story. Scientists have discovered that Mars once had a mild temperature of 64 degrees Fahrenheit. They deduced the temperature from a rock found in Antarctica that had a wild ride starting four billion years ago. (Of course, the scientists again ignore the “creation science” account and misjudge the age of the rock by just short of four billion years).

Here is how it happened. The rock was formed just below the surface of Mars billions of years ago. Then, around 16 million years ago, a meteorite hit Mars — turning the rock into a meteorite itself and flying off the surface of the planet. It then landed on Earth 13,000 years ago in Antarctica. It was then found in 1984.

This year, a group of scientists sliced open meteorite ALH84001 and tested it at the California Institute of Technology. It yielded the first evidence of the surface temperature of Mars through an analysis of the carbonate minerals.

So to wrap this up, Mars was really cool; this little rock is really really old and these guys are really really really smart.

  1. People who are opposed to having their remains cremated need to rethink that position. When the sun becomes a red giant, its size will exceed the size of the earth’s orbit. It is safe to say the results are 100% predictable.

  2. So, all we have to do is figure out how to move the Earth’s orbit out to a comfortable distance….

  3. The sun will remain a normal low mass star for about another four billion years, which is halfway through its low mass sequence. However, we only have about another billion years before it gets too hot to sustain any life as we know it on earth. Earth will probably be more like Venus at that time, where it is hot enough to melt lead on the surface at the present time.

    After four billion years it will become a red giant for a few billion years and then after nebulizing, fade to first a white dwarf and then a brown dwarf. It takes about thirteen billion years for the cycle to go from protostar to burning out its fuel and going dark as a black dwarf.

    All the lawyers out there make sure your clients have their wills up to date.

  4. According to a NASA scientist, some of those meteorites had microbes on them:

    Richard Hoover [Ph.D. NASA / Marshall Space Flight Center] has discovered evidence of microfossils similar to Cyanobacteria, in freshly fractured slices of the interior surfaces of the Alais, Ivuna, and Orgueil CI1 carbonaceous meteorites. Based on Field Emission Scanning Electron Microscopy (FESEM) and other measures, Richard Hoover has concluded they are indigenous to these meteors and are similar to trichomic cyanobacteria and other trichomic prokaryotes such as filamentous sulfur bacteria. He concludes these fossilized bacteria are not Earthly contaminants but are the fossilized remains of living organisms which lived in the parent bodies of these meteors, e.g. comets, moons, and other astral bodies. ” (Link)

  5. Woosty=^..^

    🙂 Unless it’s been suspended for some reason a new rover is suposed to lift off before the end of the year.

    I took losing the Spirit rover personaly, it really made me sad. Her twin, Opportunity, on the other side of the planet contnues to function and is looking for someplace to spend the winter the last I read. They outlived their initial mission by 6 or 7 years so they’ve done us proud.

  6. As our sun ages it will get warmer, meaning Earth will be getting warmer (we are talking billions of years here so, no, this does not mean global warming is not man-made). We may get to be more Venus like as temps & pressures rise. This warming will affect Mars also &, if the components still exist, could make it earth like.

    But shortly (on a galactic time scale) the nuclear engine will have burned enough fuel that the sun will collapse just enough to cause it to explode a tiny bit & fry everything out past Mars. We have about 5 billion left so enjoy them ;D
