re: NASA Rover Finds Conditions Once Suited for Ancient Life on Mars

This is a pretty good article:

LINK

quote:

There are really three reasons: for the science, for the challenge, and for the future.

As far as the science is concerned, Mars is the planet that is the closest to us that could have supported life in the past and may still do so in the present. And so by going to Mars and exploring those dried-up lakes and river valleys, and drilling into the subsurface groundwater on Mars, looking for fossils, looking for microbial life that may yet persist, we’ll be able to determine if life is a general phenomenon in the universe or if it is a phenomenon unique to the Earth.

We’ll discover if we’re alone or not, because we now know that planets are plentiful in the galaxy. And if life evolved commonly, wherever there is a planet with reasonable conditions, and any star has reasonable conditions at an appropriate distance, then life is common.

And since the entire history of life on Earth is one of development from simpler forms to more complex forms, displaying greater capacities for activities and intelligence and evermore rapid evolution, if life is everywhere, it means intelligence is everywhere. It means we’re not alone. This is something that thinking men and women have wondered about for thousands of years. It’s worth going there to find out.

The second reason is the challenge. I think civilizations are like individuals. We grow when we’re challenged. We stagnate when we’re not. And a humans-to-Mars program would be an embracing challenge for our society, particularly for our youth. It would say to every young person: learn your science and you can be an explorer or pioneer of new worlds.

And out of that challenge, we get millions of scientists, engineers, inventors, doctors, medical researchers, technological entrepreneurs. These are the kind of people that drive society forward. You might view it as a tremendously powerful investment in intellectual capital.


And then, finally, we should go to Mars for the future. Earth is not the only world. And if we go to Mars, we’re beginning humanity’s career as a multi-planet, spacefaring species. If we do this, 500 years from now there will be new branches of human civilization on Mars and, I believe, on many worlds beyond.

When those people look back at our time, what will they consider of what we’re doing today to be significant? What we did to make their civilization possible – new worlds, new countries, new nations with new languages and new histories – that’s what’s important.

"Conditions once suited for life" is like saying I've found evidence I may have once had 100,000,000,000 dollars because I have a back yard suitable for storage of said money.
it's worse than that for me. they are basically saying that they found conditions once suited for earth like life. IMO, it is much more realistic that our "condition for life" test will fail to detect alien life, because we don't have examples of that life.

having the right conditions (ie, water, air composition, sunlight, etc.) is not comparable to having a large area in which to store money.

This.

That was a poor analogy, although I understand where he is coming from. That said, I do not agree with his assertion.

it is essentially worthless unless we assume that all life in the entire universe uses water, air, sunlight, etc., just like Earth life does.

I still dont get how any of that shite even matters? cant we just focus our time, energy and resources on this little planet?


Some people don't realize NASA has one of if not the highest ROI's of all government programs in the country.

Simple things like cordless power tools wouldn't be available to you if not for NASA pushing boundaries.

It is when:

1. The "conditions" for life are loosely defined and, practically speaking, not really defined at all
2. still somewhat disputed by biologists much less physicists and space experts

It's not really saying anything except the basic acute ingredients correlating to the existence of living organisms was probably once there in some form in some mixture in some amount.

Basically, I found an empty suitcase therefore I found possible proof of once having 1 million dollars.

so lets just go out and say every planet has life because we don't know if creatures can live off of just methane gas.

we look for what we know until we find something that proves otherwise. it's not a hard concept to understand.

thanks rome.. i am not trying to come off as closed minded and/ or lacking the scope of this endeavor to the benefit of humanity.

I get what you're trying to say, but the empty suitcase is a very poor analogy.

I would use weather as an example. sometimes you have the perfect conditions for rain, but it doesn't storm.

no, i understand why we are looking. and, i think it is great to study with the tools we have and the knowledge we have. I just think they need to be more honest with people. they are finding evidence that life as we know it on Earth could have possibly survived on Mars in the past.

We are essentially looking for an environment, not life.

Once global warming caused all the ice on Mars to melt and run off onto Earth, that place was doomed.

I think everyone knows we're still researching places suitable for human colonization and possible migration in event of a world ending scenario.

meh, i would say the majority would say we are looking for alien life. and saying that the conditions were once suitable for ancient life will continue to lead people down that pathway.

Hey, no problem

It's kind of hard to look at it with a big-picture perspective, especially with all of the chaos going on in this world today. But NASA has benefited our society so much with its space endeavors that go very unrecognized. A lot of the knowledge we enjoy today sprouts from the experiments performed up there
