NASA ain't saving nobody...it is a detection and monitoring system. They are just going to tell us where a strike would hurt the most and tell those people to get religion or get outta Dodge..
Detection and monitoring - correct. Let’s see if we can detect the planet killers in real time, in time to deflect or otherwise defend against them. The second part will come along. Whether or not anybody thanks us, we will save the planet. Just, not tomorrow.
