re: NASA to Announce Mars Mystery Solved this morning (?)

Yeah work with a wife of NASA big wig. They apparently found water.

What is the mystery though?
Isnt this a discovery, not a mystery solved?

They need to drive their probe over there

They have long since found evidence that flowing water existed on Mars at one time. a big announcement would they found water CURRENTLY flowing on Mars, even bigger would be they found salt water currently flowing. That would all but guarantee that there is microbial life somewhere there.
While I think it means it's possible for there to be life, I still doubt there is life on Mars today. Between the very thin atmosphere and high levels of radiation that bakes the planet due to the lack of a stong magnetic field, I'd say chances of life being there today are very remote. Now that's not to say that at one point in the distant past there wasn't life there, that's entirely possible.

You're going to trust a site that has "life on Mars" rock shapes on their site?

Anyone with a channel and time for this press conference?

NASA TV or NASA's website will probably be the best bets.
I believe it begins at 11AM(EST).

So, 45 minutes?
ETA website says 1130 eastern.

Am I the only one who thinks it is weird that we always assume that life has to have an Earthlike environment to survive? Who's to say microbes there didn't evolve over the last several million years to thrive under the radiation and less pressurized atmosphere?

Humans are extremely and brutally arrogant. It had always been our downfall.

I'd be interested to see how salty that water is to maintain liquid though.
That's more of a problem to life than the pressure and radiation.
Remember, life would most likely be underground.

Then we'd find microbes in space...
Oh wait...there are microbes in space.

What do you mean by this?
Salt is so ductile of a rock, you can almost treat it like a plastic solid - really slow moving liquid.

Not that I agree with the level of his dismissal:
Radiation can be worked around in a number of ways.
The very very low pressure is a legit issue though.
It's almost a vaccum.

I mean the fact that it needs to have a dissolved solute to stay liquid at Martian temperatures and pressures.
It is kind of a moot point celebrating water and it's implications for life if it is running at 20+% salinity.
Life may find a way, but there is a limit to how stacked a deck you can expect it to fight.

I never said it was impossible, just improbable. Along with the thin atmosphere and lack of a magnetic field, Mars also lacks nitrates in it's soil, which all life that we know of needs. It also has far too much carbon monoxide in it's atmosphere. If there were life on Mars there should not be that much CO. Here, you can read the details in this article...

Not necessarily. They need food. They wouldn't be floating in space because it is a pure vacuum (mostly). There is an abundance of CO2 in Mars atmosphere they could be feeding off of. Maybe they are what is creating the trace methane that was found in the Mars atmosphere as well.
Obviously just spit balling around here.

So nothing cool?
Posted on 9/28/15 at 9:30 am to TigerFanatic99
There isn't an abundance of atmosphere though to make that worthwhile
If there is life on Mars, they are chemotrophs living under a microbial turtle shell that would put tanks to shame.
They have to use co2, but it won't be much.
Or they live in a place where the co2 vapor pressure is much, much higher.
