You cannot sterilize a human laboratory. Even our gut bacteria represent an unavoidable risk. Much better to build robots that we can stick entirely in an autoclave and sterilize, from surface to core, before sending to the Mars surface.

And there is a severe contamination risk. We know of bacteria that exist deep with the crust of Earth that, if you were to transport them to far beneath the Martian surface, would be able to live just fine. We know of extremophile bacteria that live in rocks on the surface of the most arid deserts of Earth that could likely survive just fine in a similar Martian environment.

You need to be thinking on the scale of millennia here. I think Mars should be explored by humans in Mars orbit, tele-operating humanoid robots on the Martian surface. Think Avatar except regular robots. Look at the state of how humanoid robots are developing right now, with remote presence via haptic suits or similar. Think of where that technology will be in a hundred or two hundred years. It's very plausible that we will be able to operate such a machine in a way that feels indistinguishable from actually being there. And humans in Mars orbit would be able to operate them in real time.

I'm sorry, but your vanity is not worth the sacrifice of a world. Your pride is not worth us giving up what may be our one chance at finding a second Genesis in this star system. Realistically, it will take literally thousands of years of development of a human colony on Mars before it could credibly serve as a true backup to Earth, able to actually survive the destruction of Earth. Realistically, if you want a backup of Earth, you're much better doing it in some mile-deep bunker on Earth, in a deep ocean settlement, or on the surface of the Moon. It will take a thousand years of development to turn Mars into a true backup of Earth. And I'm not even talking terraforming here, just the time to build up the population and truly independent supply chains. Waiting a few centuries to make sure we're not ruining our one shot at this is not worth your pride. Yes, that means we in our time lose the glory of landing the first human on Mars. But that is a sacrifice we make for our children and our children's children. We do not have a right to take that risk, just for our own vainglorious pride.

And yes, there may be other chances of life around Sol, but we have no idea of the habitability of those ice shell moons. We don't know if life can even get going in such an environment, as we don't really know how life got started on Earth. We do however know that life got started here, and we do know that early conditions on Mars were much more similar to the conditions on Earth's surface than some ocean world buried under miles of ice. Mars is the only other terrestrial world in this star system that could plausibly have extant life near its surface. We should not sacrifice what may be our only chance to find it, for the sake of our vanity.

Leave. Mars. Alone.
