of days. what i mean is they're doing it for real. tonight nasa is going to use a rocket to launch a spacecraft into space that has one goal. they're going smash the spacecraft into an asteroid at 15,000 miles an hour. the idea is to try to see by smashing this spacecraft into it, they can knock the asteroid off its course just a little bit, just in case some asteroid in the future like the one in "armageddon" really does end up on a collision course with earth. this is their proposed test method for knocking the asteroid off course. the mission is called the double asteroid redirection test, d.a.r.t. and the rocket they're sending it up in is not full of handsome, swarthy oil rig workers. but if all goes well, that is going to smash into the asteroid with enough force to change its directory. fingers crossed.
