Quote:They weren't trying to blow it up, they only wanted to spend millions of dollars to create a momentary flash and a small crater.
Quote:It is too bad that it was not done. We could use the data from the explosion to determine the size of a blast we would need to divert a threat to the earth.
Quote: On Earth most of the blast of a bomb is the overpressure of the air and the shock wave that follows. There would be no (very little)shock wave in space to breakup the object. Or am I looking at this wrong.

Quote:I'm thinking that if an asteroid is relatively solid, a penetrating bomb could burrow in a few tens of meters maybe into the regolith before it detonates. The energy shooting back out through the entry hole could act a bit like a nozzle, propelling the whole body just a nudge in the desired direction.A really loose asteroid would probably just fragment, though.
Quote: If given the choice between total extinction vs mass death, but non-extinction, isn't the latter less negative than the former?
Quote:When it comes to nuking asteroids I have read before where scientists claim nuking an asteroid might be bad because it would send many fragments at Earth which would still do damage, but I do not understand this rationale.

Quote: Quote: If given the choice between total extinction vs mass death, but non-extinction, isn't the latter less negative than the former? If those are the only two choices, yes. But as I recall, they didnt simply oppose nuking an asteroid, they proposed alternatives like landing a thruster on it to nudge it away intact, or coating one side with reflective or absorptive material to cause solar light pressure to nudge it over time, etc.In other words, if the choices are between total extinction, mass death, or no damage at all, they prefer door #3.Jarad
Quote: If there is time. All of the plans work on the premise that there is enough time to develop, test and launch the strike. If we don't have the time and can only launch some of our ICBMs at it, would the explosion do anything?
