didymos. 14,000 miles an hour. the camera images will not be able to distinguish these two objects from each other until the last hour of the mission. until then, they just look like -- before that, they just looked like a single point of light. so you need to have your spacecraft smart enough to use those images and target dimorphos and hit dimorphos as close as possible. that is where this smart technology comes in. it is a really good technology for planetary defense, for targeting these objects. we don't know what dimorphos looks like, we don't know it's shape. from other asteroids we have been to, we know they have a hole variety of shapes. there is extensive testing that has gone on in order to meet this challenge, and we are looking forward to the demonstration. host: give me a sense of all the years of development and the teams involved once the idea was that we were going to try and affect the trajectory of this asteroid, what kind of craft would be capable of doing that question mark how did the process e

from earth you cannot separate didymos from dimorphos. we really did not know what the asteroid looked like. the draco imagery uses the navigation at the end of the mission to ensure we hit dimorphos, which is a challenge in itself. host: is the autonomous navigation technology new technology? guest: yes. the autonomous navigation, smartnav, is one of the challenges and the new technologies for this mission. we are targeting an asteroid that is 140 meters in diameter. this will be the smallest object nasa has sent a spacecraft to. to complicate matters, it is going around didymos. that is 780 meters in diameter. and you are coming in so fast. 14,000 miles an hour. the camera images will not be able to distinguish these two objects from each other until the last hour of the mission. before that, they just looked like a single point of light. so you can clearly see that you need to have your spacecraft smart enough to use those images , fire the thrusters and target , dimorphos and hit dimorphos as nearly head-on as possible. that is where

didymos dims for a second and then brightens. so we know that there is something there passing between us and didymos. we know that little moonlet is circling around. it takes less than 12 hours for that moonlet to make it around that astroid. less than 12 hours. or at least that's how long it took before tonight because we earthlings maybe just changed that. about ten months ago nasa launched a rocket at that little moonlet. seriously. the hope was that the rocket would smash into the moonlet and knock it off course, nudge it enough to change its orbit. something like this had been tried before in the movies. it had never before been tried in real space before tonight. a couple of hours ago the smash happened. and we've got footage thanks to an onboard camera on the nasa rocket. this is what the astroid and its moon looked like as the nasa rocket approached and then a few minutes later came the moment of impact. watch. >> three, two, one! oh, my gosh!

dimorphus orbits didymos roughly ery 12 hours.es to speed it up by at least 73 seconds. to see if it works, astronomers will point a few dozen telescopes on every continent and in space at the asteroid. planetary astronomer andy rivkin is a lead investigator. newtonian physics would tell you that this is going to perturb this rock. andy: absolutely. miles: what do we have to understand further at this point? andy: we do expect to make a lot of ejecta, as we call it, when dart hits. that is also carrying momentum. how much bang for the buck are are we going to get? miles: and we can watch the bang as it happens. dart is designed to transmit live images of its death dive. must seev. ask any dinosaur. for the pbs newshour, miles o'brien in laurel, maryland. william: miles, this is a tremendous, schmidt, and seeing the self joy in the mission control room tonight, i wonder if you could for a moment reflect on this accomplishment today. miles: it's pretty rare when you see scientists applauding a crash. but also this is a pivotal momen

didymos is moon-lit, called dimorphos. it is what the spacecraft is targeting. time, just a little over 15 minutes from now. and the reason the images there are still so small, alex, is because this spacecraft is traveling at four miles per second, not per hour, just per second. so pretty soon we're going to see this asteroid fill the entire screen. and you know, alex, for billions of years, all the inhabitants on planet earth have had to take it when it comes to asteroids. they've had no defense. tonight for the very first time, earthlings are going to try to strike back. >> that small dot is getting bigger. miles, what are you going to be looking for? >> i'm enjoying the ride, just watching it get closer, alex. but it's really interesting to understand what is going to happen afterwards. we know that this spacecraft will perturb the orbit. the question is how much? and what is slightly counterintuitive is scientists will be looking at the plume that is created by the impact. it could actually give them a little more bang for their buck. it could create more mo
