Prince*Jedi Posted May 29, 2013 Posted May 29, 2013 The idea of capturing an asteroid may seem unbelievable to most. Yet following U.S President Barack Obama's instructions to Nasa that he wants to snare an asteroid and then launch it into the moon/earth orbit, the space agency has released a video of how it could be done. This is all part of the development of a potential manned mission to Mars. How Nasa intends to capture an asteroid ? Here ( full video by Nasa for the first time) : http://link.brightcove.com/services/player/bcpid694908207001?bckey=AQ~~,AAAAjgltpmk~,3G6d8W41NOS8dBzRXeWHGdzbg-FWShEX&bctid=2292355746001 2 Quote
Chameleon Posted May 29, 2013 Posted May 29, 2013 Dude, that is amazing, or will be if they pull it off Quote
Prince*Jedi Posted May 29, 2013 Author Posted May 29, 2013 Dude, that is amazing, or will be if they pull it off Ya! That is crazy I recommend watching this video in full screen ( after some seconds of commercial) Prince *Jedi 1 Quote
Antichrist Posted May 29, 2013 Posted May 29, 2013 That'll be interesting seeing what they find, if anything. I'm also curious what they're looking to find, that's driving them to do this... 1 Quote

*Appel* Posted May 29, 2013 Posted May 29, 2013 crazy... typical for USA. all ideas are crazy, but they really let some dreams come true. (Moon and so on) Quote

ajnl Posted May 30, 2013 Posted May 30, 2013 crazy... typical for USA. all ideas are crazy, but they really let some dreams come true. (Moon and so on) Why is it crazy? That'll be interesting seeing what they find, if anything. I'm also curious what they're looking to find, that's driving them to do this... I think they are looking into mining asteroids and possibly into how to divert asteroids if they are in a collision course with Earth. But that is just a guess. Quote
Stevy Wonder Posted June 4, 2013 Posted June 4, 2013 This is good, actually, this could prevent the extinction of the human race, of course just from an asteriod colliding with Earth. Quote
+Maluco. Posted June 4, 2013 Posted June 4, 2013 A space Anaconda!!!! Thx for sharing it not enough rocks in Texas i guess Quote
Death_Reincarnated Posted June 5, 2013 Posted June 5, 2013 Interesting but getting the trajectory correct will not be easy, especially when there is a delay in the information sent between central command and the capture probe. The asteroid will have large momentun due to its weight and having enough thrust power to stop it will also proove diffiult. Quote

True, but that is why they calculate the path of the asteroid, so that they won't need to make major adjustments later. Momentum will definitely be a problem. Quote
StealthNinja Posted June 5, 2013 Posted June 5, 2013 Damn that's cool if they pull it off... but what if they don't or can't? Quote
Death_Reincarnated Posted June 5, 2013 Posted June 5, 2013 (edited) True, but that is why they calculate the path of the asteroid, so that they won't need to make major adjustments later. Momentum will definitely be a problem. 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 Edited June 5, 2013 by Death_Reincarnated Quote
EmtHipple Posted June 5, 2013 Posted June 5, 2013 Right then if they do " capture" a asteroid and bring it into a near earth orbit getting it to go away and not come back to bit us in the ass might be a trick too. Just my thoughts on it ' Quote
