Mars is the planet nearest to Earth that we are most likely to explore and send manned missions to. It also is the planet that we have the best chance of finding life on. For both these things water is needed so exploration of Mars by space probes has concentrated on looking for water.
Humans have searched for evidence of water on Mars for many years. In 1895
American astronomer Percival Lowell thought that he had seen canals on the surface of Mars. These were disproved as tricks of the eye. Spacecraft in the 1960’s and 1970’s reported that Mars was very dry. However, spacecraft in the 1970’s to the 1990’s started to report evidence of water, either past or present. The atmosphere of Mars is very thin, only 1% of the

An additional resource that I found confirms this work. It was in a United Press article released in December 2002. The article is valid as it summarises and backs up data from NASA. It has been known for some time that the poles have frozen carbon dioxide, (dry ice) but more data from the Mars Global Surveyor probe has shown that the height of ice in the North Pole is higher than dry ice alone could be. This suggests water is tied up in the polar ice caps. This was confirmed by Odyssey.
People had suggested water had existed near the surface of Mars but now scientists had conclusive proof. Although this has answered a lot of questions it has raised many more. As yet not enough water has been found to explain all the features seen in the early life of the planet. the relevant scientific information on water on

In 2004 two probes, Spirit and Opportunity, arrived on opposite sides of Mars. Both probes have confirmed old findings and discovered new evidence for water. They have found:
• Clear stratification in the rocks – as found in the Endurance crater. http://www.newscientist.com/article.ns?id=dn6077 • Sulphur and chlorine,
3. For years Mars has been known to have water in the form of ice.
But what about a planet more than 200 times farther away. If we can colonize on Mars the whole world will believe that anything's possible. People will never give up and keep trying to reach their goals. Although people on Earth may be mad that scientist used 6 billion dollars, but it went to good use. It was used to giving hope and making people believe. Now we should go reach our dreams by going to Mars.
For many years scientist from all parts of the world have encountered the idea, “Was there life on Mars, and is there still today.” Never has a Scientist been one hundred percent certain, but a few have been pretty darn sure that life has and still exists on Mars. Bacteria and water have said to be found on Mars a long time ago but is there still bacteria and water on it today. Probes from NASA have gone to Mars to find any kind of lifeform and found samples of water and maybe bacteria. With this finding scientist want to claim for there to be life on Mars but in order to claim that more evidence is needed. At one time Mars was said to have an ecosystem as strong as Earth’s.(Savage, Early Mars) Water was an extraordinary finding for scientist, and the fact that Mars had a very strong Ecosystem gives scientist the upper hand.. The argument about life on Mars can be very well debated on both ends, but the evidence leans more towards that life can and perhaps does exist on Mars.
evidence to show that water is in existence today. Looked tidally by Mars are two moons;
Mars is the planet that is most similar to earth for various reasons like similar seasonal patterns.
I believe we should go to Mars because by studying Mars, we could advance into the study of the other planets in our universe, increase our astronomical research, and continually advance our systems and
Water on Mars is very hard to find. Since the planet used to have water most of it is frozen underground. “The bad new is that most of that water is frozen underground and likely contains toxic chemicals.” The water that is dug up would have to be purified and preserved. Georgie’s father said that in the canyon there was “water-soluble mineral deposits” near the edge of the canyon. Georgie’s father said that “ I figure drill 400 meters down, and we’ll hit water”
Later, orbiting spacecraft such as like NASA's Mariner 9 returned far more detailed data on the planet's atmosphere, mapped its surface, revealed Martian topography, and captured many more images of this strange and distant world.
Would you believe me if i said there was water on mars, probably not, so i´ll explain, Nasa (
Finding proof of potential life on other planets seems way out of reach but is has been attempted for the last couple years. In fact, new discoveries made by NASAs Curiosity Rover and its team was brought out very recently. In the news there was an article, “NASA Curiosity Rover Discovers Evidence of Freshwater Mars Lake”, about the rover that may have found evidence of an ancient lake. Through these discoveries scientists of NASA have made a hypothesis that Mars was in fact Earth like, not just the desert that we know it as today. They believe that Mars had many swimming holes that were part of a wet environment that could potentially have supported living life. These life forms could live on Mars because of the environment that was once similar to earth’s. One of the major craters that they were looking at which supported this idea was called the “Gale Crater.” This specific crater is known to have rocks that were around 4.2 billion years old, and said to be from a running water lake. This idea has just been developed from a long lasting idea that Mars did have some water but its quality was like battery acid.
Glaciers are one of the most fundamental phenomenon on the planet, and much of their purpose and impact on earth has been well documented and published. Ice sheets, Ice Caps and Glaciers trap nearly 90% of the world's fresh water, and are replenished by snowfall each year. Their existence on this planet dates back 650,000,000 years and yet they are always moving, always shifting and always melting. Before, human existence and even during the brief era of humans, ice dominated all of the earth's landmass and have regulated, created and altered many of the landscapes around the world.
Today the world now knows for sure, that water flows on Mars. Hydrated minerals on slopes of Mars were found on mysterious streaks of land using a MRO. These streaks appear to flow down slopes during warm season and then fade when the temperature drops. This is the first substantial evidence to support that there is water on Mars. I think that this is really cool because I still believe that on day we will have to live on Mars one day. I don't necessarily want to in my lifetime, but I still think it would be very cool none-the-less.
Data taken from NASA's Lunar Prospector, which orbited the moon in 1998 and 1999 revealed some ice deposits at the end of each pole. Now, ice deposits found at the poles is nothing new, but it's where these ice patches are that's making the news. By connecting the two ice spots with a straight line, the body's axis was created, yet this was offset by 5.5 degrees. While confusing, scientists believe that may have an explanation.
