Anaerobes can only live without oxygen. When the Earth’s ozone started to form, over half the world’s organisms of anaerobes died off and later evolved to become aerobes, which can only survive with a constant supply of oxygen. Scientists believe that the high surface temperatures on the dark areas of Mars may be explained on the presence of living vegetation placed upon a dry vegetable mold. Coblentz, a scientist of physics and astrology, created a theory that ... ... middle of paper ... ...is or ever was life on Mars. Bibliography Burgess, Eric.
Some investigators wondered if the abiotic production of organic materials in the soil was absolutely basic to the origin of life. Maybe some organic materials from elsewhere in the universe had arrived in the early earth. Statistics have showed 7.5% of rocks from Mars reached Earth. These rocks would travel between less than 100 years to 16,000 years and more to get to Earth. Some proponents include Gyon de Montlivant, who proposed that life came from moon, H.E.
Mars is like Earth in many ways, but it is also different. Mars has water and ice which is why scientists believe plants can eventually be grown on Mars (space.com). Once the plants are grown, oxygen can be formed and strengthen the atmosphere (space.com). When the atmosphere is thickened then the planet will be livable by humans (space.com). Scientists’ ultimate goal is to have human life on Mars which can be... ... middle of paper ... ...ost of what scientists know and need to know about the conditions of Mars is know from the Skylab, Mir and the International Space Station.
It is suggested that all the planets are the same age, therefore to determine the time of different event on other planets Earth is used a reference. He also explained how tectonic plate helped to resurface Earth, which erased this history of this planet. In this chapter he also discussed theories of how life began here on Earth. Later in the chapter, he discussed the Moon and the theory of its creation. Corfield also discussed the first space mission to the moon.
The next mission was titled Galileo Millennium Mission which lasted till 2001. Europa and Io are the two main focuses of this mission but there were also studies done on the effect Jupiter’s radiation was having on the spacecraft. Unfortunately, Galileo began to run out of the fuel it needed to fine-tune its orbit and continue to have its antenna pointed the correct way to earth. Rather than taking the risk of losing control of the space craft and having it crash into the moon Europa, contaminating it, they decided to have it crash into Jupiter’s atmosphere in September of 2003.
For humans to permanently live on Mars, a fuel source must be used. Fossil fuel sounds like the perfect candidate for this being that it puts out C02, a greenhouse gas. Which in turn would kill two birds with one stone because we need to warm the atmosphere anyway. But fossil fuels can’t be used on Mars because of the C02 atmosphere, but magnesium can be. Not only can magnesium be used in mars’ C02 atmosphere, it’s already on the planet.
They could be tested for things such as evidence of fossilised organisms. Another, possibly slightly far-fetched hope is that we may find simple organisms like bacteria actually living on the desired planet. These ideas spanned from the discovery of rock on our planet that originated from Mars; knocked from the planet when a comet collided with it. In 1996 a group of scientists created conflict by ... ... middle of paper ... ...them is so great that they are dragged to our planet. Another idea is that UFO's are not really from other planets at all, but created right here on Earth.
But the amount of ice is nowhere near to what it should be if all the water on the planet froze. Maybe the water all evaporated into the atmosphere, leaving behind the dry rocky surface we see now. But then why is the atmosphere of Mars so thin? Perhaps all the water soaked into the ground and remains disperses in the soil deep underground. Knowing the history of water on Mars is the key to understanding the entire history of its climate and how planets evolve, including Earth.
Concept of a large exploding star or nova near the solar nebula is based on evidence that our sun is not large enough to generate the heavy metals in the inner planets. The evidence of life on this planet occurs in some of the oldest rocks found on earth. The source of water on earth is from comet debris. Compaction by the weight overlying layers is least likely to have led to differentiation. Evidence from the Iron Catastrophe is based on the discovery of the layered structure of Earths interior.
The earth is a self-regulating environment; a single, unified, cooperating and living system - a super organism that regulates physical conditions to keep the environment hospitable for life evolution therefore is the result of cooperative not competitive processes. In the mid-1960's, Dr James Lovelock was approached by the NASA, who asked him for help in searching for life on Mars. In 1965, Lovelock proposed some physical tests for determining whether Mars held life or not. He proposed that a top-down view of the entire planet be employed. The test would analyze the composition of the planet's atmosphere.
