There are heavy discussions in other threads about why it is important to compute asteroid properties or detect new ones and what we can do in case we find out that a big rock is going to hit Earth. So I opened a thread specifically to discuss this. Other threads mentioned that we have little means to stop larger asteroids from colliding with Earth. This is not entirely true. I saw a video about plans to deflect asteroids using nothing but sunlight :) They are experimenting with using huge mirrors to concentrate sunlight on the asteroids. Concentrated sunlight is surprisingly strong. With just a few moderately large mirrors they can concentrate enough light to melt iron instantly. the plan is to focus a very strong light beam on the asteroid, which would start melting it in one place. The meting would result in the asteroid starting to emit vapor, which is supposed to change its course :) http://iqjar.com |

How good the asteroid detection is is obviously a very important question. Does Asteroids@Home ever plan to run tasks which aim to detect new asteroids? Currently it's only computing properties of existing ones. Orbit@Home had this purpose but it's frozen and dead. For me it would make sense for A@H to also do this. |

Good point. http://orbit.psi.edu/ says, A new version of the system is in the works, and we expect to bring it online in the 2014-2015 period. But as I know this project it will last until 2017 and then they rerun a batch of old wu's to 'test the system'. It's really time to pick that up and start a new project or integrate it into an existing project. I would support it with more cores attached to the project. |

Another method discussed for deflecting asteroids is a 'mass driver', where a craft is landed on an asteroid & it then digs up & fires off chunks of the rock into space in a direction that gradually pushes the rock away from earth. But in my original post in the GPU thread I was under the impression that mikey meant immediately available options (I see I was wrong & that he actually said 'foreseeable future'. But anyhow, as far as right now goes, AFAIK the only available options are nuclear missiles & the gravity traction method using a random but suitable satellite. Well, the first question should be: how good works the detection of asteroids? How much time will be left before impact, how many objects fail to be recognised? Are there numbers available? Well a quick google shows that NASA's doing a fair bit of tracking :) http://www.jpl.nasa.gov/asteroidwatch/ I know that some amateur astronomers are also watching out, in fact a couple discovered the 1 that exploded over Russia recently. Also NASA are trying to get other people involved http://www.topcoder.com/asteroids/tracker/ Team AnandTech - SETI@H, Muon1 DPAD, Folding@H, MilkyWay@H, Asteroids@H, LHC@H, POGS, Rosetta@H, Einstein@H,DHPE & CPDN Main rig - Ryzen 3600, 32GB DDR4 3200, RX 580 8GB, Win10 2nd rig - i7 4930k @4.1 GHz, 16GB DDR3 1866, HD 7870 XT 3GB(DS), Win7 |

How good the asteroid detection is is obviously a very important question. Well, I have been thinking about it. But there is a problem. This is really time consuming. If the Asteroids@home would do this, then everything about it I would have to do myself and the problem is that this is not my full-time job. So this is in a long term plan if my situation changes. But I would really like to start it. |

Maybe you get some help from your team? Would be great to bring 'Orbit' to a new life ... |

But I would really like to start it. If I were a rich man, God knows I'd offer you 10 times what they pay you at your current job, to work full time on A@H :) Unfortunately I'm not :) Maybe one day somebody with the appropriate financial resources will recognize the potential and importance of this project and enough people with the appropriate expertise will be able to work on it and focus on it 100%... |

As I understand it NASA have agreed to fund Orbit@home, it just hasn't got off the ground yet, indications were it would be this year........

@ Kyong It is possible but detection of asteroids is also different from deriving physical properties or calculating its orbits. It is not easy to detect asteroids because of huge space. Many discoveries are from amateur astronomers. Doing some planned sky-survey based on telescopes is difficult if you are able to imagine the huge space in our Solar system and how the telescopes work. So this is something where searching new detection methods is needed for increasing efficiency. The important thing for us now would be searching the collisions courses but as you can see, everything depends on having enough time to do it. |

Last modified: 18 Jul 2014, 17:45:07 UTC Ok, I guess I do not understand what A@H really calculate, I get the feeling we are mashing numbers with out a clear usage. Just what are we currently doing or what data are we creating and to what usage? Yea, like he said that info is here http://asteroidsathome.net/, & from the main page. Oh & linkified for you Kyong ;) Team AnandTech - SETI@H, Muon1 DPAD, Folding@H, MilkyWay@H, Asteroids@H, LHC@H, POGS, Rosetta@H, Einstein@H,DHPE & CPDN Main rig - Ryzen 3600, 32GB DDR4 3200, RX 580 8GB, Win10 2nd rig - i7 4930k @4.1 GHz, 16GB DDR3 1866, HD 7870 XT 3GB(DS), Win7 |

There is an organization dedicated to the detection and ultimately course correction of potentially destructive asteroids. You can read about it at: http://sentinelmission.org

Former NASA astronaut Ed Lu recently posted this: http://us5.campaign-archive1.com/?u=c7281b61ab362fadf221e16fc&id=8714e101b5&e=2fdb82295{ to commemorate the second anniversary of the Chelyabinsk event. Ed Lu is a co-founder and CEO of the B612 Foundation which has, as a principal project, the asteroid detecting Sentinel Mission infra-red space telescope. He flew on STS-84, STS-106, Soyuz TMA-2, and ISS Expedition 7. |

This URL hosts a slightly less than 2 minute video that shows how the Nuclear Test Ban Treaty Organization has detected 26 explosions caused by asteroids in the period from 2000-2013. http://www.space.com/25590-asteroid-impacts-eart-day-b612-video.html |
