Should we send humans to Mars ?

Even if we do overcome the technological hurdles in reaching other worlds, should we actually go there ?

Living and working on a planet such as Mars would be one of the greatest challenges humans have ever faced, not just in traveling there but in building and maintaining a habitable environment afterwards. But what of the potential to contaminate the environment with bacteria from the Earth ? Whether deliberate or accidental, contaminants brought to Mars by astronauts would have the potential to drastically affect the environment. In the far future it is even possible that the planet could be terra-formed to be more Earth-like.

"Forward contamination is a critical factor in space exploration," said John Ash from the Scott Polar Research Institute who has likened planetary exploration to drilling down in to Antarctica's hidden lakes. "Of course, it is critical not to contaminate samples that may offer scientific proof of extraterrestrial life; but there are also legal obligations."

"For humans to live on the planet for any significant period of time would require the recycling of water and air, along with other so-called "life systems"."

And how will private business help exploration? Private business is there for profit, nothing else. It does nothing for the greater good, only for greater wealth. It may be great for putting tourists into space but it isn't going to poor billions into searching for microbes on Mars UNLESS if can profit from it. Politicians may not be my favourite animals but remember Columbus discovered America and Cook discovered Australia on government financed missions.

When did national governments ever do anything for the greater good? The examples of what happened after European government-sponsored expeditions discovered (or perhaps stumbled upon) other cultures doesn't exactly suggest that they were interested in doing it for the greater good, does it? Surely exploitation was the beginning and end of the motivation. 'Tis a good point I grant you, however government's and politicians are in the business of at least giving the appearance of doing things for the greater good. They will invest in projects to impress the people (either their own in the case o... [More]

Looking at this from a logical angle I think we should think about getting off this planet because all the things which man are doing to this planet is not doing it any favours! Eventually the Earth is going to be pushed out to the position where Mars is as the Sun is expanding very subtley, and it will probably take at least 500,000 or more years to push Earth out that far, so the planet Mars will be in the exact position we are in at the moment so we will be in the habitation area for life to flourish. So, get your thinking caps on human race we've got 500.000 years to Terraform Mars for us ... [More]
