Water Found?

-
Let's presume that the "Mars Exploration Rover Spirit" sent by Nasa does discover water.
What are the future considerations?

Well, with liquid water, this would be the perfect breeding ground for a chemical reaction. Be it organic or inorganic. Anything organic would prove that life exists on Mars. Anything inorganic would indicate that there is a potential for future chemical reactions or that reactions have occured depending on the molecule(s) discovered.

I am not convinced at this stage that we will discover any complex molecules or organisms on Mars yet that would have derived from the presence of water.

We will have to keep our eyes open to see what the Rover Spirit uncovers.

New Life on Mars

-
Lets say that no life is found with this current Mars mission and subsequent unmanned Mars missions. Nasa may decide to create a semi permanent settlement on Mars. This would involve creating our own air, water and food supplies. This would not be a simple task. Transporting the necessary equipment at this stage with the astronauts is not feasable due to cost and craft size limitations. We would have to send ships in advance. One to handle the creation of drinkable water from the frozen ice if H2O is discovered. Then the creation of oxygen for breathing and hydrogen for fuel, again from this water. Food will be another problem and if plants are to be send in the form of seeds, or plants, a greenhouse with the proper atmosphere will have to be created prior to mans arrival to ensure sufficient supplies. What if Nasa or some other organization decides to make Mars more permanent? Who's to say that this decision of who goes and what the long term purpose will be is all up to Nasa? Wha...

Will We Ever Set Foot on Mars?

-
Currently with the US government in huge debt and the cut backs to NASA, it is very unlikely that anything new will happen in the coming years as far as Mars is concerned. I do feel that eventually we will set foot on Mars. Most likely in another 40 - 50 years from now. Anything attempted sooner is surely bound to fail since I feel we have not invested in deep space research to attempt a manned trip to mars or any other spacial body beyond the moon. A manned mission to Mars should involve landing and establishing some form of base for future manned missions to continue on a regular basis. Unless we visit Mars regularly, I cannot see the point in ever attempting to set foot on Mars in the first place. Is terraforming Mars a possibility? Is this even something remotely being considered by the Nasa experts? I do feel that we will reach a breaking point on Earth and we will have to move beyond our own planet for mankind to survive, about 50+ years from now. The resources alone on...

Spirit and Opportunity

-
It will be 6 years on January 4th when the first rover landed on Mars followed by the second on the 25th of January. Spirt and Opportunity were originally slated for a 90 day operation each. I cannot believe and I am certain that all the engineers that worked on the original design probably cannot believe that these land rovers are still in operation after all these years. How does a remote vehicle designed for a maximum 90 day operation running on a temporary battery and solar panels still operate after all these years? Spirit has travelled 7.7 Kilometers and Opportunity has travelled 18.9 Kilometers. This does not seem like a long distance in almost 6 years but I can just imagine how much science has been completed within this short distance travelled. It was less than 2 months after the first landing that one of the rovers discovered that water was present on Mars at one point. After almost 6 years there has not been any evidence found of previously living organisms as far as I kno...
