Many scientists in the past few centuries have been curious if life on Mars is possible or if it has ever been before. For this purpose, in the past century, scientists have sent several probes and experimental vehicles to the Red Planet to prove that there is a possibility of life on Mars. In the 1960s and 1970s, US Vikings and Soviet Mars probes were sent by scientists and reached Mars. Data from the Viking landers proves that there were water molecules present on the planet. The experimental vehicle, Curiosity, was sent to Mars to prove that these water molecules actually came from lakes, streams or rivers.
We are able to study these space rocks using probes and infrared rays. Asteroids, comets, and meteors are commonly used terms for the objects moving through our solar system, but these rocks have a bigger meaning. One type of space rock is a comet. Comets contain methane, carbon dioxide, ice, ammonia, and dust. Put all these substances together and you get a comet.
Some proponents include Gyon de Montlivant, who proposed that life came from moon, H.E. Richter, who suggested life came from meteorites or comets, but Svante Arrhenius proposed this theory. While this idea may seem straight out of a science fiction movie, some evidence suggests that an extraterrestrial origin of life may not be such impossible idea. One argument that supports the panspermia theory is the emergence of life soon after the heavy bombardment period of earth, between 4 and 3.8 billion years ago. During this period, researchers believe the Earth endured an extended and very powerful series of meteor showers.
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.

Another idea is that UFO's are not really from other planets at all, but created right here on Earth.
Analysis of “The Moon: Cold, Wet, and Breathing.” The article “Top 100 Stories of 2009 #16: The Moon: Cold, Wet, and Breathing” from DiscoveryMagazine.com discusses the LCROSS mission of 2009. This is a Moon mission conducted to search for the presence of water (Barone 2009). The mission is an important part of the ultimate goal of visiting the Moon and establishing a Moon base (NASA 2005). The article is written to expand upon what occurred during the LCROSS mission (Barone 2009). LCROSS stands for Lunar Crater Observation and Sensing Spacecraft.

Photovoltaic panels will power the living units on Mars. There are limitations to this mission because of the cost budget. One problem that might occur later in the mission is how the astronauts on mars will get the necessary resources they need to survive. Because there is no way to tell if the water on mars is able to be consumed, Earth must send ample amounts of water sent to Mars (“Technical Feasibility”).
Is Mars Colonization a Good Idea? Among celestial bodies in our solar system, Mars is remarkable in that it possesses all the raw resources required to sustain not only life, but a new branch of individual evolution. The time to colonize Mars would certainly be required when the Earth becomes uninhabitable as the global warming rises up. When that happens, Mars has the potential to become the most habitable planet in our solar system. Nevertheless, even with positive extrapolation of robotic manufacturing techniques, Mars will not have the labor required to make it fully self-sufficient; until and unless its population is in millions.
Scientists believe that the earth’s gravity caught some of the debris and pulled it into the earth. Scientist Digregorio, Barry E (B4) stated that inside the debris of falling rock, were microorganisms. He notes that the microorganisms may have been the very start of life, as human civilization knows it. There is no way to prove his theory true, but it is a strong possibility. Similarities in planets led scientists to believe there is a common bond between Venus, Earth, and Mars.
The Pathfinder, which landed on the surface of Mars was one of the missions, and the Global Surveyor, which is a satellite, is the other mission. Although Europa has no set missions yet, The Galileo Spacecraft has passed within 364 miles of the moon Europa and has taken images that have given scientist a good look at the surface ("Oceans on Europa" Internet). The next proposed mission is a vehicle placed in orbit around Europa that would have a radar sounding system designed to look through ice. A further step may be taken by landing a vehicle on the surface. One thing scientist are looking at very hard are ways to get humans to these places.
Martian meteorites that have landed on Earth contain evidence that justifies the presence of life in space. First, we are certain these meteorites are in fact from Mars from measuring and matching their noble gas ratios to that of Mars (McKay et al. 1996). Findings within the Allan Hills (ALH84001) meteorite by a team of NASA researchers ignited immense interest in the subject of martian life in 1996. The team discovered polycyclic aromatic hydrocarbons (PAHs) as well as globules of carbonate a... ... middle of paper ... ...rites to the atmosphere of Mars.
