Title: Water on Mars
Post by: carlb on September 28, 2015, 01:18:33 PM
I never heard that they actually saw flowing water a decade ago! Interesting article

QuoteNearly a decade ago, Nasa's Mars Global Surveyor took pictures of what appeared to be water bursting through a gully wall and flowing around boulders and other rocky debris.

Interesting find , if it's accurate.

Round up all the libs and send them there to protect the water, and the illegals to work the future fields.

I've never seen the appeal of "colonizing" the place. It'll never happen. Mars really is no different than the moon. The atmosphere is nearly nonexistent, it's VERY, very, very cold (although the pictures from there resemble our desert) and if the cold, or the lack of a real atmosphere doesn't kill you, the radiation will.

Mars is believed to have lost its atmosphere very early in its existence because of the low gravity and the lack of a magnetic shield.

Earth has just enough of both to prevent the atmosphere from being blown away by the solar wind.  We would have lost our atmosphere too if not for the protection of our magnetic shield.

Hmm...
IF no atmosphere then no H2O.  IF VERY, very, very cold then the H2O would be frozen in no time at all.

Sorry, but NO. You should read more carefully. Mars has an atmosphere. It's VERY (very, very) thin. It's mostly CO2 (carbon dioxide, and nitrogen.

QuoteThe atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide. Here's a breakdown of its composition: Carbon dioxide: 95.32 percent. Nitrogen: 2.7 percent.Aug 3, 2012
http://www.space.com/16903-mars-atmosphere-climate-weather.html

Temps are like the moon (250 above during the day, 250 below zero at night). Mars can get to 50 degrees in the summer sun. But then there's night. CO2 freezes to "dry ice" at 110 below zero. That's what's at the polar caps, and it gets below that, even at the equator.

QuoteIn winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C).

The water is saturated with a special salt (not our table or sea salt). This allows the water to become liquid at temps below zero.

Hope that clarifies

No magnetic shield creates all kinds of problems - communications are limited to line-of-sight, and the radiation - wow!   If airline pilots have a higher incidence of cancer (supposedly induced by excessive exposure to radiation), how long would anyone expect to LIVE in that environment?

I trust NASA as far as I can throw them.  And I shouldn't throw anyone with my bad back...

I am filing a grievance as there only sending 4 at a time.   What ever happen to it's cheaper by the gross.  Send no less then 144 on the first trip.

Think sardines, now envision shipping containers in the same manner, all packed on the largest container freighter in the world, thennn... imagine dozens of those ships stacked on the largest barge.
Now, put rockets on that baby and shoot it to Mars,  we could easily pack several million libs into one shot. :biggrin:

Just join with me in spreading the word that you can get a much better high on Mars because of the gravity...

Why send them anywhere? Just have them sniff the rocket fumes.

Ya know what's really sad though?
We could send 10 million, Hell, a hundred million libs to Mars, and still, the planet would be void of intelligent life.

Well unless they were to take a dog along.   :biggrin:

How confused will they be when they know it's 95% CO2 and -300 degrees...

The irony of being a lib, is they are generally to blame for failed city infrastructure, socially and culturally, but they are always the first to claim that mans is destroying the planet.
So libs very existence is a conundrum, in that they destroy by their very existence.

They'll go to Mars, build and expand, destroy the environment as it's known today, uninhabitable,
They'll pound the atmosphere with gamma rays to heat the atmosphere in an attempt to create a livable habitat, which in truth would be deadly to current life on the planet, much in the way man does to earth by his very existence, we terraform the planet to suit humanity, which threatens other specie that prefer a man free environment.

Quite the conundrum for a lib when they think about it.
The best thing they can do for the planet, is off themselves before they do anymore damage.
