Do you think NASA/ESA should try deflecting non-Earth crossing asteroids?
Scientists have been saying for years that we need to come up with a plan to deflect an incoming asteroid. But I've never heard one say we should try different plans to see if they work. Considering the number of huge surprises in space science it seems odd to me that we'd wait to do this until there is one coming. We might only have a few years to devise a plan, build the equipment then send it out. What if it utterly fails?
