If life is discovered on Mars, and I mean actual living bacteria, not just
fossils, will the discovery affect the way we proceed with colonization or terraforming of the planet? I mean, if Mars is alive and we start bringing terrestrial plants and various other organisms, wont it be just like bringing dogs and rabbits to Australia or Kudzu to the US? In my opinion, it is the same, but I think we should do it anyway. It seems clear that life will never go beyond the microscopic stage on Mars. Mars is basically a dead-end as far as life is concerned. So I think that if we can, we should make whatever use of it benefits humanity. I just think there are others who will not agree. I think that if some of the upcoming Martian probes find life there will be a vocal minority who will argue that we should never send people there (and maybe no more probes) because of the risk of infecting the existing ecosystem. |

We might have to nuke it first, to get rid of it.

We should not terraform Mars during my lifetime. Future generations won't
care what I think. If there are bacteria, there might be worms or shrimp. It would take time to fully inventory Martian life. I'll guess that terraforming will start in 2125. |

That would be an amazing accomplishment if we could do it in your lifetime though. I think nanotechnology might be required, and it might be necessary to use nanotechnology to extend your life so that it can be accomplished in your life time. As for not leaving any stone unturned, how long do you think it will take to overturn every stone on the planet Mars. If Martian life is not "in our face" when we land, we shouldn't worry about it too much. Tom |

It would be legitimate grounds for going a bit more slowly and cautiously with exploration and colonization, to make sure that the native life was reasonably well understood before terrestrial contamination became excessive. (Even now, with most researchers fairly sure that there is no life on the Martian surface, precautions are taken to limit contamination. Landers are not routinely sterilized -- that's costly, and hard on electronics -- but attempts are made to *reduce* bacterial load.) The final decision on terraforming will be made by Mars's inhabitants, who will be in a better position to assess the pros and cons of altering their planet than people still living on Earth. I mean, if Mars is alive and we start bringing terrestrial plants and various other organisms, wont it be just like bringing dogs and rabbits to Australia or Kudzu to the US? Not unless there are environments on (more likely, in!) Mars where terrestrial organisms can grow and reproduce. The reason why people stopped sterilizing landers was the growing certainty that it's pretty much impossible for Earth bacteria to grow and spread on the Martian surface. -- MOST launched 30 June; first light, 29 July; 5arcsec | Henry Spencer pointing, 10 Sept; first science, early Oct; all well. | |

I'll guess that terraforming will start in 2125. I've always been excited about the possibility of terraforming another world. However, as a biologist, I concur with Mike Rhino's opinion. If life is discovered on Mars, it will likely be our only example of extraterrestrial life for quite some time. It would be a crime against science to make wholesale alterations to the Martian ecosystem, before we understand it thoroughly. I would guess that terraforming of Mars, if it is ever done, will not begin until considerably later than 2125. We have had hundreds of thousands of biologists researching life on Earth, for several generations, and we're far from hitting bottom. Assuming that there's any life to find on Mars, I would guess that, by 2125, not even a hundred biologists will have visited the place. We'll have more questions than answers. -- Rainforest laid low.
