ajnl Posted June 5, 2013 Posted June 5, 2013 Indeed. The simplest scenario would be that the asteroid is moving along a linear path, but the problem is applying enough froce from the thrusters to stop it. One may apply force over longer period of time to affectively stop the asteroid but we all know that the path of a astronomical object tends to be orbital so then the force would have to be diverged from a linear force - and this is where it gets ugly lol. Oh and just going back to applying a force over longer time - how much fuel would you then need lol. For those interested have a read - http://en.wikipedia.org/wiki/Momentum They probably have to find something else to use instead of fuel. Also it only needs to be reduced to a speed where it can orbit the earth, correct? Quote

It is definitely possible to computationaly project the trajectory but the major problem is, like you said, fuel/thrust to produce enough force to alter the path/momentum of the asteroid. It is indeed a good idea, in theory, but in practise its a totally differnt ball game I'm afraid. Current rocket thrust mechanism would not suffice - maybe NASA is already working on ion thrust drives hehehehe. Edited June 6, 2013 by Death_Reincarnated Quote

But if they could, than rockets would have enough power to do it I think. Everything has to be theory first Quote
pawuszka96 Posted June 20, 2013 Posted June 20, 2013 What if they want to use it as a weapon? Small asteroid hits a Moscow (for example) and no one suspects USA. Quote

cobvious Posted July 7, 2013 Posted July 7, 2013 This is WAY cool! It will be interesting for sure. Quote

Gorilla Posted July 9, 2013 Posted July 9, 2013 Very cool if it could actually happen. I guess they are thinking ahead just in case some random rock is headed to earth. Then they wont need Bruce Willis. Quote
critterKiller Posted July 9, 2013 Posted July 9, 2013 this actually made my day Characters from Armageddon would have been thankful for this technology Quote
