Nasa Mars announcement: is there liquid water on the Red Planet? - live

Has Nasa has found liquid water on Mars? Follow the build-up ahead of the announcement from 4pm UK time

Is this like asking if there are rocks on the moon??? I'm sure that hydrogen and oxygen are bound to mix somewhere else other than Earth???

Well call the Starman himself. Maybe Ziggy could re-establish communications with Major Tom, who may be able to answer the question about 'Life On Mars'. After all, Space (is an) Oddity...

O that was so lame, I know...

[CoupeKing]

I've been trying to follow this for the last few days, exciting stuff. I'm sure it should be something substantial.

[Madaya]

My guess is evidence of flowing water. Though on Mars it would be a concentrated brine solution. We shall see.

[mik]

It appears water it much more common than than first thought, which is good stuff , it makes it easier to find another place to live before we blow ourselves up ...... or the sun expends its fuel source and grows to a size that envelopes our little rock before it shrinks again to buggerall, but not before it turns us into crispy critters , ...............i always look on the bright side .

It's sandworms...right? Gotta be.

Shai Halud be praised!

The Mrs gave me a book saying that's where men came from. I'll lend NASA the book if they want and save them a ton of money.

Saying there was life on mars because there is evidence of water, is a little like saying there were holdens on mars because they found iron oxide.

Or a wife beater and a empty bundy can?

One commonality of all know life is the presence of liquid water. Both In the creature, used by the creature and near it. This illustrates a special condition present where all know life could live. So empowering the imaginations that fund, research and build these missions its a close as we have come.
Exciting stuff

The mind boggles though. If life is found on Mars, no matter how microbial, the automatic assumption would be that God or evolution has been very active all over the universe...

Salty water seen flowing on Mars, not far from Curiosity rover

NASA’s Mars Reconnaissance Orbiter has captured the strongest evidence yet that salty liquid water flows on the planet’s surface during warm seasons.

Whether or not these salty flows could sustain life depends on how salty they are, says Lujendra Ojha of the Georgia Institute of Technology in Atlanta, who has reported the findings, along with his colleagues. “If the water is completely saturated with perchlorates [hydrated salts], then life as we know it on Earth wouldn’t be able to survive in that sort of concentrated water,” he says. “But if the water only has a tiny percentage of perchlorates in it, then I think we should be fine.

Recurring slope lineae – dark streaks that appear, get longer, and fade in each Martian year – have long been thought to represent signs of flowing water. Now that idea has been backed up by data from the Orbiter’s onboard spectrometer, named CRISM, which analyses reflected sunlight to detect patterns that indicate what minerals are present on the surface.

Salts can absorb water from the atmosphere and lower the freezing point of water, making it possible for liquid water to exist even in the cold Martian climate. Spectral data from four locations with recurrent slope lineae reveal the presence of hydrated salts, which are most likely to be magnesium perchlorate, magnesium chlorate and sodium perchlorate.

Although not examined in the current study, features resembling recurrent slope lineae were observed this year in Gale crater, raising the possibility that the Curiosity rover could look for more clues up close.

The most promising location is about 50 kilometres from the Curiosity landing site. Curiosity has already found evidence of perchlorates at Gale crater, as well as organic compounds.

Confirmation of flowing water on the surface would add substantial weight to calls for NASA to commit more strongly to searching for life on Mars. In the Atacama desert, one of the most hostile environments on Earth, communities of microbes are able to survive on moisture in the ground created by salts absorbing water from the atmosphere. Some think, similar microbes could live on Mars.


More signs of water? (Image: JPL/NASA)

A number of astrobiologists criticised NASA when plans for its next rover, Mars 2020, left out DNA sequencers and other devices designed to look for living organisms.

But many scientists would not be convinced by evidence from a rover. Definitive proof of life on Mars would require samples to be brought back to Earth. Mars 2020 will store samples to be brought home in a later mission.

“The only thing we can really assert is that the places we’re finding are probably more habitable than the rest of the planet, which is bone dry,” says Ojha.

Totally agree Trevor 57, but I still wonder if ET will be found in my lifetime. That will have serious impacts on society I think...

Ah, that old pile of rubbish...
No, there aren't...for the money spent it's staggeringly cheap when you compare it to other "worthwhile" things we spend money on here on Earth, and the rewards could be staggering.

But that doesn't matter...the human race doesn't advance by sitting in our houses and feeling sorry for ourselves as some people would prefer we do...we have to go further and expand and strive to discover everything there is to discover.

Here's just one figure to put things in perspective...


Oh, and we haven't "wrecked the Earth", it's not "dying", or any of this other green based rubbish we hear. The planet is fine...it's faced a hell of a lot worse than mankind burning a little coal. It was here for billions of years before us, it will be here billions of years after we're gone...stop worrying and crying into your beer, and revel in human achievement for a damn change!

Spiritual well being doesn't get you to the stars...cold hard facts are how the world works...how the universe works. Spiritual stuff is all inside your head...it doesn't exist beyond what you think exists, and has literally no place in the world of science and human advancement.

I remember back in the seventies we looked forward to a 21st century full of unlimited expansion and plentiful atomic power, but somewhere along the way cowards got put in charge of things...and we're just bumbling around now advancing slowly and steadily. Where are the big thinking projects? Where are the plans that the public jumps behind feet first like they did with the moon landings and earlier space exploration?
A couple of setbacks and they chicken out...backed by navel-gazing green idiots who think we should be ashamed of being able to flicjk a switch and have easy access to energy.

You really wonder if that bright future is ever going to happen if we keep limited thinking like that...

Perhaps there are plenty of big thinking projects, plans people are jumping behind feet first, maybe you just disagree with them? or and are blinded to them through personal bias.
The world is changing, many on here complain about it, many say its for the bad, "wasn't like this when I was a kid nor part of my big plan", buts its happening, for many, in their opinions, there are developments and projects that rival the moon landings and the greatest human stories.

[zoesgift]

has anyone noticed the pictures of the surface of mars showing supposed changing amounts of water on its surface being shown in all these news stories are close to or over 4 years old.....gets the alien theorists putting forward all these theories of what nasa and similar type agencies actually really know. where is fox and scully when you need them!?

[castellan]

Man will never even survive on the Moon, in fact no one has even been back their from the so called first landing and some say that the fact is, no one ever landed at all, but it's just a way of spending tax payers money for what ever pollys want to do, maybe like all the child molesting supporting crap they have done as well as any degenerate load crap like Political Correctness or funding Communism to prop all the good for nothing grubs up.

Who the hell would want to live on another planet, let alone go their and if there was another living being out in the universe, I don't want to know them, bloody hell we have enough problems dealing with people amongst the world as it is.

Could you name some JP? Do you think the super collider in Switzerland is one of those projects?

The SSC (Superconducting Super Collider) that was scrapped in the 1990's was designed with proton energies five times greater than the LHC.

I wont here as this thread is about mars, yes the LHC is amazing, research knowledge and unlocking new avenues for research and development. Not as macho as strapping a rocket to your butt and heading for the moon but arguable more important and more epic.
I like science, design and problem solving and see many of the great big pictures in these spheres.
Social, moral, economic, artistic and environmental progress all great stories, rarely carried out by heroic white men walking with swaggers, more likely a unassuming somebody in a white lab coat.

It wasn't cowardice that caused the technological stagnation instead of the world envisaged by many in the late 60's and 70's. Immense wealth and power are vested in the status quo and maintaining it. Had technological progress akin to that during the post-war period up until Apollo kept on going through the latter half of the 20th century, we would have had sizeable colonies on Mars by now, decentralised energy generation in every household running on scraps, viable alternatives to plastics, non polluting highly efficient transportation (private and public) and many more other innovations.

We don't because such technologies free humanity from the shackles of servitude.

As for the announcement today, it just reminds me of how much I miss the NASA of old.

Cool we can have a new place to live once we ***** this planet completely.

The best headline today. Water on Mars: Australia to search for illegal boats.

[wodahs]

Hmmm they recon space travellers visited us in our ancient past !!!!

I wonder with this finding was that the planet we screwed and left behind them many many many years ago , and now some bright spark after realising we going that way (again) may be we could go there

or even more still mars had water , so mars had life like earth , so what screwed mars and will it happen to earth before we can screw it

you could argue we are, at least our solar systems, E.T. off visiting foreign worlds with out robots and spy craft and even our peoples.
