Icy Asteroids Move aside buddy, I need to vaporize some water NASA/JPL-Caltech/T. Pyle

Back in April, two teams of researchers caused a stir when they discovered the first-ever evidence of water ice and organic molecules riding around the solar system aboard an asteroid. Today, the same group has announced that it has found ice and organics on a second, larger asteroid as well, a finding that suggests water ice and organic molecules may be common passengers aboard asteroids throughout the solar system.

Asteroid 65 Cybele, a resident of the asteroid belt between Mars and Jupiter, has been found to be harboring both water and organic molecules, which are of course the building blocks of life. So while it may seem like an incremental discovery (after all, we found ice and organics on one asteroid so why should we be surprised to find it on a second?), it suggests that 24 Themis – the ice-harboring asteroid discovered in April – likely is not an anomaly. In fact, watery asteroids could be quite common in our solar system.

That’s significant news, because it means there might be a whole lot more water in our solar system than we originally thought. Researchers now have to evaluate the way they’ve been differentiating and classifying asteroids and comets – asteroids are generally viewed as rocky while comets are perceived as icy – and revisit the theory that asteroid impacts are what seeded Earth with the ingredients for life, a theory that appears to be bolstered by this discovery.

Of course, this also raises interesting possibilities for future generations of deep space travel. You need two key things to send a manned mission deep into space: fuel and water. The hydrogen in water can be split to provide fuel and oxygen, and naturally the stuff sustains human and plant life. If water ice is indeed circling the solar system in huge volumes on the other side of Mars, the asteroid belt could become a deep space filling station for future manned mission to the farthest regions of the solar system.

heres an idea, if there is significant amounts of water in the asteroids then what if we change the orbit of a significant number of them to impact mars, enough impacts could increase the martian mass increasing the martian gravity, increase the water levels, the energy of the impacts warms the planet up some, by useing controlled impact locations the rotation speed might be increased or decreased to make it more nearly earth like.

the only thing I see as a drawback is the near lack of a martian magnetic field, unless we can find a way to jumpstart that process any water or atmospere added will likely just fizzle away again.
not to mention no significant magnetic field means little protection from solar wind radiation.

How do we divert asteroids?

a grappling hook and a tow rope

a small rocket engine, just enough to nudge it good.
once the existing orbit is changed it may take years or even decades before it reaches mars and impacts but no one ever said changing planets would be fast.
so it could take a long time before the first one impacted but after that they would be coming in a heavy stream how meny per week or day would only depend on orbit calculations and how much effort one wants to put into finding and moving them.

Nasa wants to find a way to protect earth by diverting asteroids, they want to be able to find them very far away and give them a shove while they are very far away becouse the further away it is the less force it takes to move it enough to make a differance.

one idea seems a little far fetched to me, simply having a space craft near an asteroid, no rockets or lasers or bombs, just being near and useing the almost unmeasurable gravity pull of the vehicle itself, the guy who came up with this idea thinks if you do it far enough away from earth that ohh so very tiny pull could over a large distance be enought to completly miss earth, and if that is the case then the push of a toy rocket would be greater and could be enought to change an orbit, mind you it may take two or three ;) but really, a small rocket like the ones used to boost a navy VTOL aircraft off an carrior would easly change an asteroid orbit.
calculating how much force to apply where to apply it and for how long to get it where you want it, that is the real trick, and computers are really getting good at that stuff.

I suppose that is good news for the astronomers and nasa/jpl folks who have said for years that comets are just ice. (I even heard a jpl representative say that recently.) Of course they learned the truth of the matter after several probes did close fly-by's and found them to be coal black rocks -- and the huge tails were actually adding to the rock, not subtracting from the ice. You can read more about what causes that phenomenon at jmccanneyscience.com

The story jogged my memory back to a Buddhist scripture I read some years back. Researchers today are close to know what people know more than 2500 years ago.

Repeatedly smashing the Martian surface would definately throw the plant out of obit, which could be potentially dangerous for Earth. I say we should leave the rocks in place. They occupy a great position in conjunction with Jupiter for defending Earth against potential impactors. Not to mention, the filling station idea is a novel one.

Mars is almost as big as earth, the asteroids would be only a few miles in size or so, knocking mars out of orbit would be like throwing a single kernal of corn at you and expecting it to knock you off your feet.
you would have to throw something much bigger maybe the size of the moon or maybe half that, or you could excelerate it to increadable speeds, but then to add enough force to the rock to significantly smash mars you would have to make it a big part of the speed of light.
no, your not going to knock mars out of orbit that easy, ohh and this is not actually my idea, it's an old one that scientists much smarter then I worked out decades ago.
the big differance is now we know there is large amounts of water there so we can make a wet atmospere and seas on mars.

Given;

body mass (kg)
Earth 8.976E+24
Mars 6.419E+23
65 Cybele 1.78E+19

Thefore;

It would take 468,208 bodies the size of 65 Cybele in increse the mass of Mars to equal the mass of earth. Such a feat of planetary engineering is a century or two beyound us.

also the presence of water in asteroids throughout the solar system and the universe also dosent rule out the fact of the whole human race and all life in the universe came from asteroids instead of this creationism theory.

of course asteroids would have water, think about a low gravity planet with geysers, or even volcano's shooting the water and rock out of the low gravity.
