Introducing/Seeding life in mars

Could we seed life into mars, a lot is known regarding the martian atmosphere and environment. Would it be possible to send samples of lifeforms from earth to mars.

    humans will never be able to inhabit mars. even if we set up some sort of indoor dome to live in, supplies would be hard to come by. you can not grow any crops at all. also, its not as if you could just pop back to earth to get some grub!

    an interesting question, but it can not and will not ever happen.

      Apr 30 2011: I believe that most mars Terraforming plans tend to start off a little more modestly, introducing genetically modified bacteria into the planets ecological system. Then vast amounts of water and CO2 would then be added to the atmosphere, thus increasing the planets temperature. Fauna and flora would only be introduced after a stable planet temperature and atmosphere are established.

However, the sooner we start terraforming mars to have a more favorable atmosphere that contains both oxygen and water , the better suited this planet will be for colonization and a staging point for inter-solar system exploration.

    While these life forms would be interesting to study(if they exist). for comparative Xenobiology studies, a stable colony on mars, trumps all of the information we could gain from these comparative studies.

      Apr 29 2011: That is a major concern, and I remember reading somewhere that that might of happend.

      I know, that's a great reference right? haha

    Apr 27 2011: I like the idea of it! Why not right? Kick start nature on a new world with a mix of bugs and mold that can survive and set up a platform for more complex life to take hold! Long term terraforming!

    Some people might want to keep Mars pristine until we can study it and learn more about it. A reasonable argument.
