Personally I expect an ELE that requires major effort to deflect we would fail due to such infighting and not allowing for the inevitable failures. (SpaceX: To deflect that rock we need 80 hits with nuclear-tipped Starships, launches starting in two weeks. Given the inevitable failures of such a pace please fund and arm 100 rockets. Congress: Here's 90. SpaceX: 78 hits, it's too late now.) | |

| Oct 2, 2021 at 21:51 | comment | added | Amazon Dies In Darkness | @DJG COVID-19 was discovered in, well, 2019 (no Kellyanne, this isn't the 19th COVID - complex.com/life/2020/04/kellyanne-conway-covid-1). Here we are nearing the end of 2021, and the majority of the world's population still has no access to the vaccines (almost all the vaccines have gone to a handful of rich nations). So to answer your question, yes. | |

| Oct 1, 2021 at 14:06 | comment | added | DJG | Do people really think bureaucracy would still move at a snail's pace in the face of a species-wide imminent threat? I don't. | |
| Sep 30, 2021 at 23:58 | comment | added | Famous Jameis | @RockPaperLz-MaskitorCasket you assume western countries would be the ones managing such projects. | |
| Sep 30, 2021 at 10:54 | comment | added | Amazon Dies In Darkness | ...could we avert it...? By the time the committee was approved, organizational rules decided upon, officers elected, roles assigned, a plan created, and funding received to possibly implement a prototype, the Earth would have a very sizable dent... and, of course, if anybody survived, some minority group would get blamed as the scapegoat... | |
| Sep 30, 2021 at 10:37 | comment | added | PM 2Ring | As I mention here: astronomy.stackexchange.com/a/39875/16685 The Earth's orbital speed is around 29.8 km/s, thus it covers a distance equal to its own diameter in around 7 minutes. If you want to determine if some rogue body is going to hit the Earth, your trajectory calculations need to have that level of precision. (That 7 minute window is for a body in the ecliptic plane heading towards the Sun, so it crosses the Earth's orbit radially). | |

| Sep 29, 2021 at 16:39 | comment | added | astrosnapper | Planetary Defense Conference and FEMA tabletop simulated exercises (link to previous exercises at CNEOS) have focused on 100-300 meter sized impactors not extinction-level ones to make a more likely and feasible scenario. The scenarios also tend to have somewhat contrived detection times and visibility to make a more challenging scenario where you have to make tough decisions based on incomplete info. For the OP: how much warning time between detection and impact are you assuming ? This makes a major difference in the possibility of any mitigation plan. | |
