Since no one know if life is common or if it only exists on earth, would you like for the U. S. to send a manned mission to mars to search for life?

Ancient Ocean on Mars

Though we see Mars today as a cold, barren, arid desert, there is a wealth of evidence that the Martian surface once ran deep with liquid water oceans.

The fact that around 4 billion years ago the Red Planet enjoyed a warm and wet climate not dissimilar to Earth has fueled the scientific investigation of the planet as rovers and other robot missions search for signs that the planet once harbored life.

An ancient ocean on Mars

A new set of topographic maps featured in the Journal of Geophysical Research: Planets presents new evidence for an ancient ocean.

The team behind the study found evidence of a roughly 3.5-billion-year-old shoreline with sedimentary accumulation at least 900 meters thick in an area in the northern hemisphere of Mars. This substantial build-up of sediment covers hundreds of thousands of square kilometers and implies the existence of a massive ancient ocean.

The paper also offers the strongest argument yet in support of the idea that Mars once experienced sea-level rise that is consistent with an extended warm and wet climate.

If we could discover that life on Mars still exist or did exist in the past, that would strongly indicate that life is common throughout the universe; especially if any RNA and/or DNA is different than what is found on earth proving that life on earth didn't originate on Mars.

Failure to find life or any remains of life on Mars would be more evidence, that we may be alone in the Universe.

It would be fascinating to the extreme. Who wouldn't like know the answer to this question?

We'd have to expect life to have happened in a similar way and be DNA/carbon based. Life exists on earth in quite hostile environments but did it originate in hostile environments?

I would love to read some speculations on how it could have happen on Mars. Have you seen anything?

I'd like to see a manned mission to Mars just to show it can be done

Strangely enough I've just been reading this article.

I saw an ad recently for applications to live in a Mars simulation for a year doing specimen testing education and research. It will be the second group. Maybe you should apply? I personally have zero interest in the Mars hype train. I don't want to ever visit or live on Mars nor do I believe it will be helpful to mankind in my lifetime.

I am already on a list to be one of the people sent. I have the clearance for such a journey I have the mental and emotional fortitude and I have the expertise to do so. They have a lot of candidates but I have had 7 different meetings in the last 3 weeks regarding it.

[AviatorTom]

Unmanned missions are far less expensive, less dangerous, and can last longer. There are several devices on and around Mars already looking for signs of life.

[Kelley1]

They have no intelligence above worm so they can't do much.

[exitseven]

yes, I always thought it was a shame that the US stopped sending manned space missions after we went to the moon.

[FunkyMonkee]

OF COURSE there's life on other planets! What else could be visiting us from Zeta Reticuli, etc. if there's nothing else out there?
As for Mars, we're already there looking for life! Kinda weird since that's where we came from.

[normalice]

We have a rover already doing that. Anyway, mars is hardly the end of the universe. If we call it "looking" to look on Mars we're not a serious species.

[lightbulb27]

doubt we find much living in these other planets, it be some other solar system. I'd rather not see a mission to mars, that be one harrowing journey. probably happen inside 50 years.

[Surely]

Don’t remember where I saw this. But there is speculation that life as we know it didn’t originate on earth?🌍 What happens if we find life and they are not friendly and don’t want company?

[BoopBoopBeep]

There's a buncha people I'd like to send to Mars now that you mention it...

[KrakenAttackin]

I'm tired of Mars. We only go there because we can actually get there. We need to go to Europa, which is the best bet for life in our solar system.

[standardguy]

We kniw from the bible abd orher sozrces that there are other worlds with living beings. So trips to other planets are not necessary.

[Anonymous]

No. I'd rather we send people there to colonize.
