Is There Life On Mars?

[6EQUJ5]

I shall be shocked if we do not find life on Mars. There have been landings on Mars and devices exploring it from China, America, Russia, United Arab Emirates and Europe. Japan has yet to achieve a soft landing. It is difficult to get there and achieve a soft landing. Half of the American attempts have been total failures. On their current effort the American craft will land and explore with a tiny helicopter, which will have to be very good technology because there is no air for it to use to stay aloft.

But it may well be that the life that is found there is that which we took there.

This is the view of Professor Paul Davies, an English bloke. His research interests are in the fields of cosmology, quantum field theory and astrobiology at Arizona State University. "I’m afraid humans have been contaminating Mars with terrestrial organisms for decades. NASA long ago gave up attempting to fully sterilize their Mars probes".

The chances of anything coming from Mars are a million to one said Jeff Wayne,how did the landing go 6EQUJ5?

Have we ever brought Mars rock from the planet?

If you had the chance to go into space with enough food and water to last a lifetime gathering information to send back to Earth but it's a one way journey would you go?

Did you like Space Dust,was that mouth crackling sweet really from space?

Which was better,UFO,Space 1999 or The Jetsons?

It's not just about the life we took to Mars, it's about the potential for life from this planet to reach all corners of the solar system due to the scale of asteroid impacts in this planet's history.

In fact, we all might be evolved from multifarious panspermia flying around the galaxy on random space debris...

We have little choice in the matter of inhabiting anywhere else in our solar system.
Starting from the closest planet to the sun and going outwards, Mercury and Venus are both far too hot for us to ever inhabit.
We occupy Earth. Mars is too cold but not to such a degree that it will be for ever impossible to alter it. After all, we know how to warm a planet. We have been incrementally warming Earth for quite some time. We will do well to ever set foot on Jupiter, Saturn, Uranus and Neptune. They are all far too cold and are gas planets, consisting largely of hydrogen and helium. They each have a tiny solid core that we know almost nothing of but which is extremely hot.

Pluto is no longer categorised as a planet. This downgrading to dwarf planet took place in 2006. There are Pluto fans who do not like that so for them I include Pluto in this assessment. It is far too cold and far too small, only 17.8% of the Earth's mass. Anywhere beyond Pluto is totally out of the question. In fact, for the reasons given above, anywhere beyond Mars is almost certainly out of the question.

So in the solar system Mars seems to be the only prospect. It would be formidably difficult to make it suitable for us to live on. But that is an encouraging assessment. We cannot dismiss it as impossible to alter Mars. What is now formidably difficult may well become feasible by the end of this century. So let's incrementally work towards that prospect, beginning now.
