Changing of orbits of big celestial bodies is impossible with this millennium's technology, but what about small moons of planets and asteroids.

 

I think that the most interesting idea would be to try drop Martian moons, Phobos and Deimos down to Mars surface. Do you guess this would be succeed. The nuclear bomb is surely the only instrument what could be used.

 

If Phobos and Deimos would fall down to Mars, what influence would this have to Mars climate.

It would destroy a good section of mars for a start.

 

As for the climate on mars, since there's no atmosphere and no liquids (none to speak of anyway), I doubt 'any'.

What about a high output laser constantly bombarding one side of the moon? This would "burn" off smalll areas causing a small amount of thrust that cumulativly over a large time span could alter the orbit or trejectory...

you might as well feed beans to lunar explorers and only allow them to fart in one direction.

yep that would work but it would take a really really long time and the cost of shipping the beans would be astronomical

To all proposals in this thread:

 

WHY?

because he asked.....

Well (a) you didn't answer the thread starter's question, and (b) that doesn't answer my question with regards to your proposal.

 

So nyaaah

Moving planet-size objects is an area I have somewhat of an interest in, because I hope we work out a way to do it before our sun explodes or a giant asteroid comes along... The only real issue in doing it (looking towards the future where the sun wouldn't be required to sustain life on eath, which again ties into..) is energy issues, which are currently one of the major limiting factors of science.

That's a good reason for wanting to move a planet, but why in god's name would we want to down Phobos & Deimos, or make the moon's orbit erratic?

s&g?

FOR KICKS.

moving planet sized objects...you guys are ambitious I was refering to his first line of moving small moons of planets and asteroids...

You'd have to be quite careful moving the moon though... remember putting it off trajectory will change the shape of the orbit into an elipse. If you can't predict that (or, more impressively, control it), the moon could swing back and hit the planet.
