If one or two asteroids hits this earth, what are we going to do. Asteroids plural would certainly destroy our planet. Even one large asteroid, like the 150-foot-wide rock that just passed within only 17,000 miles of Earth, inside the orbits of many of our satellites, was a close enough encounter to stir up hopes that clay on Mars will provide water. According to one scientist, we must find water on one planet or another if we’re going to sustain human life. The recent discovery of clay on Mars could prove water was there.
Last summer, Mars rover Curiosity excited the scientific community. The clay minerals found by the drilling are a victory for all the scientists who were championing the idea of ancient seas on Mars.
Many may not know of the debate that had previously gone on about the existence of water bodies on Mars. Once the evidence is in, old debates are rightly discarded in order to move with the new evidence. And, appropriately, that is what science is doing. Such a discovery now is just what the scientific community needs to neutralize our fear of the planet being thrown into the ice age if we’re hit by a giant asteroid.
An abundance of new evidence, and several sites in close proximity to the Curiosity landing site also showcase what a triumph this is for NASA and the rover teams. And the treasure of data coming in promises to be breakthrough after breakthrough. The possibility for ancient life, at the least, on Mars continues, and gained ground with this evidence.
It is only a hope, the Mars Life hypothesis, but it is one that romances all of us. We want to think that Life started there at the same time as here. It is now confirmed: it could have. That’s right, COULD have. Mars has no moon to provide tides and a weaker magnetic field than the Earth. There have been arguments about lava flows depositing the clay that is found, and if anything, that provides the best analogue for life starting there. The lifeforms here on earth that feed at geothermal vents under the ocean provide many species with the nutrients, and energy needed to live, and evolve. Unfortunately, life would have had to develop rather quickly, and evolve massively. It is estimated a minimum of only 150 million years for life to develop, and evolve, before losing the ocean it developed in, according to an estimate in 2009. It does not preclude life, but it limits the types, and given what we know for sure about life that developed her on earth, likely limited development to arthropod-like life at most, and bacteria-like life most probably. Perhaps what’s more exciting is that since man needs water to survive in outer space, Mars, could one day be colonized by the human race.
More samples need to be taken, and every last bit, byte, and granule of information will be extracted from the few samples available. The rover will be moving to new areas, and given the scientific evidence now, water-formed structure names are apt, and supported. Despite so many people believing in extra-terrestrial life, we may be living in the age where we actually find the evidence, so EVERYONE can believe, and that is exciting for everyone, not just the scientists. So hold off asteroids, just give us a chance to put together a viable get-away plan.
