Mars was once on track to become a thriving Earth-like planet, yet today it is an apparently lifeless wasteland. A NASA spacecraft named MAVEN will soon journey to Mars to find out what went wrong on the Red Planet.

A growing number of scientists today are questioning the entire theoretical framework taken for granted in this video. New evidence implies a highly electrified heliosphere, affecting the evolution of the planetary system as a whole. Even today we continue to discover residual electrical connections between the Sun, the planets, and their moons. What electrical events might have acted on Mars in an earlier time?

Your quite right we do live in an electrified universe and I would like to put my theory as to what caused the climate to change permanently on Mars! according to Bodes law another planet would be positioned half way between the Sun and Jupiter, exactly where we find MP Ceres today. Instead of a planet we find this space taken up with misshapen rocks of all sizes ( Asteriods ),if when reconstituted would be planet # 5 out from the Sun, then this would allow energy to flow evenly around the solar system bringing a milder climate to Mars.

I wish. Earth will be a disaster soon. Water will turn into fire and explode the sun will be meters away from earth earth quakes. Explosions and more...

Mars was too small to keep it's core molten, so it solidified and lost it's magnetic field. Also without volcanism to replenish it's atmosphere, the solar winds eroded it away until almost nothing remains. Any liquid water on it's surface would have evaporated away, been broken down by UV light and lost into space...

I always thought the Hellas Basin looked like a HUGE crater. I think that a very large object hit Mars when it had an atmosphere, and moved the molten Iron core near the surface, creating the Tharsis buldge. then the core, much smaller shifted back, and the magnetic properties were much degraded. This along with HUGE volcanos blowing gases and atmosphere off caused Mars to become what it is today.

I have an hypothesis that it is geothermal heat that keeps water on the Earth's surface. For example, water is taken into the crust at subduction zones and then rises in magma to the surface where it is emitted in volcanoes. The volumes of known groundwater are very large and I note the recent discovery of an estimated 2/3 of Earth's water in the mineral Ringwoodite in the lower mantle. If this is the case then the much of the water on Mars may have been absorbed into the Martian sub-surface as the source of geothermal heat reduced. Perhaps the rest was then driven away by the solar wind as stated in the video. Interested in Nasa's views

Perhaps the original moon to circle Mars was broken in two & that meant there wasn't enough pull to generate the same type of geomagnetic pull we have from our moon. If one of the remaining moons was larger it would give the same tidal pull we get.

Many millions of years ago in the solar system was common the collisions between asteroids and the bombing of planets were the order of the day. The Earth may have had more luck by having a shield like the Moon. In addition the two pieces of rock that orbit Mars (Phobos and Deimos) may contain clues of those cataclysms, I think we should take samples there.

So my Question is, What would the Scientist can get after they Discover the Past History or Discover that water Once flow in mars? If they can turn it back?
@TheATMproduction
@TheATMproduction 10 лет назад
It's most likely impossible, Mars cannot sustain liquid water 'cause of stuff like low gravitational pull, no atmosphere and freezing temperatures. Even if we somehow provided the whole planet with it, I don't think it would get enough energy from the Sun.

It's pretty obvious. Mars doesn't have the mass to hold on to it's lighter gases. Anymore questions??.........

How much larger does Mars need to be (gravity wise) to hold onto enough atmosphere to be a comfortable world for humankind? Lets say a few large asteroids and comets to bring it water and hold it? Lets say we aimed a few of those at it over 100 years? Then we polute the place with industry to make C02 (we're good at that on this world). There is an asteroid belt nearby with enough material to get the job done.

Within a very short time, Mars was uninhabitable to its once-proud third-dimensional populations. Where the trade and triumph of empire had sent its armies and caravans, empty winds raged and blew chilling blasts of red sand. Everywhere the evil red sand drifted, covering shattered monuments where no one any longer breathed any kind of air but that which was radioactively poisoned. As you tell about, Earth is on the brink of a similar scenario.
@TheATMproduction
@TheATMproduction 10 лет назад
If you didn't notice, Mars is smaller than Earth. That means it has a weaker gravitational pull, and during the Universe's expansion, it simply lost all of it's water. Water would not be able to sustain itself in liquid form for very long on Mars anyways because of the temperatures. So to be honest, I doubt there was ever complex life living on Mars.

Loss of atmosphere is irrelevant compared to WHY Mars lost it's magnetic field. The magnetic field on earth is weakening and the pole is moving away from the axis. Rumor claims a pole-shift phenomena but not for a while yet. The problem is if our field is weak for too long between pole shifts - how do we hang onto our atmosphere. China isn't helping either.

the magnectic field died when the core solidified. The sloar wind couldve been blown away by solar winds.
@krumplethemal8831
@krumplethemal8831 10 лет назад
nope the core of mars is not solid. Geo-thermal vents have been found indicating that it still has a molten core but not on the same scale as earth. This also accounts for it's smaller isolated pockets of magnetic fields.
@1950Viper

Krumple Themal Where that would be the greatest find ever. None I have seen not even in Olympus Mons. With the planet the surface is exposed to space and any warm plume would be picked up in infrared as a hot spot a sure thing for mineral and water extraction from steam for heat and water.

It is only mystery for those who do not know planetary evolutions. If one knows the correct version it is normal process for space bodies go through this changes. when the internal process of mars return to normal equilibrium the atmosphere will build up and magnetic filed will join to become one main global similar to earth. my experience of politic is that they don’t want to know. they like to discover the wheel again and again.

If that's the case and that's how Mars lost its water why it only happened to Mars and not earth

thoth622 I am too. I've never witnessed a comet passing before. I hope it makes it around the sun.

@thoth622 11 лет назад
ironik beatz They're beautiful. I saw comet Hale-Bopp when it made it's pass in 1997, and I was able to get a picture of come PanSTARRS earlier this year by pure luck. Earlier today I read ISON is now viewable with binoculars in the predawn sky, and it'll just get brighter here on out. Check out spaceweather.com

Our earth become like this very soon. after some billion years later some creatures like us would send some satellite or airships to find out how is the earth.and then those creatures would say ,what we saying now about mars.
