we can see dimorphos. we are underway!cally we're just going to keep plumbing along. >> right, we are heading in. >> let's talk about the next major milestone ahead of us, locking on target with dimorphos, which could happen as early as 10 or so minutes from now. right now smartnav is targeting didymos, but locking onto dimorphos means, you are consistently bright enough and i am ready to start targeting you. can you talk about what that means a little bit more? >> so smartnav is looking for bright part of the image. as dimorphos gets closer and it is brighter and bigger, smartnav will just target onto it as opposed to didymos and we will be on her way to impact. >> thank you, angela, very cool stuff. good luck with the rest of the evening. >> thank you. >> while we wait, we want to invite you to celebrate the life of a very important member of our dart team. pulling off extraordinary events requires extraordinary people. he was just that. a leader, engineer and friend. he devoted his life to making the impossible possible

once we got a look at dimorphos that . got a look at dimorphos that was — got a look at dimorphos thatt— that we were going to get it. that was— that we were going to get it. that was the one unknown. once we knew — that was the one unknown. once we knew what it looked like we were _ we knew what it looked like we were very — we knew what it looked like we were very confident in the spacecraft. were very confident in the spacecraft-— were very confident in the spacecraft. absolutely, that was a defining _ spacecraft. absolutely, that was a defining moment - spacecraft. absolutely, that. was a defining moment when spacecraft. absolutely, that - was a defining moment when we were like, yes, dimorphos exists! that was a big for everyone and then the second part was, we were expecting to see it separating away from the larger asteroid as we impacted, and then we were able to execute a textbook manoeuvre. thank you we are ready for the next question.— thank you we are ready for the next question. tarik malik from sace next question. tarik malik from space dot-com. _ next question. tarik mal

all these missions are concentrating on did, -- dimorphos. we will take confirmation on the exact period change. it won't be tomorrow but we might see some licia cube. we will see the data come soon and we will see more information from the investigation team because that was our number two goal. number one is measuring the period change and characterizing how much we put out. >> you say about two months? my second question is -- >> a couple of months before the full answer. some things will likely come out in days or weeks and saying this is what this observatory saw or this is what liciacube saw. we will get some pieces of the answers soon but i will say the full answer a couple months. >> shut all things sleep easier -- should all earthlings sleep easier? >> the first test was a success and we can clap to everyone. i think earthlings should sleep better and i know i will. [laughter] >> did anything go wrong tonight ? did you have to make any adjustments? >> no. >> it has been wonderful. >> this mission is straight down the mission -- middl

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 evolve? guest: there is a lot of paths that don't work out. all ideas are on the table at the early stages. first and foremost, dart is a very focused missions and that was very important to this whole discussion. a lot of times when you get the opportunity to fly in space, you want to be able to do all sorts of things bec

dimorphos filling the field of view. incredible surface detail of an asteroid 7,000,000 miles from earth. absolutely amazing. something for the history books. and this is the last frame from the spacecraft before confirming loss of signal. i am joined by members of the dart team that helped turned this incredible mission into science fact. ed reynolds, dart project manager at apl. lena adams, dart mission systems engineer at apl. mark, dart guidance engineer at apl. caroline ernst, instrument scientist at apl. julie bella rose, dart navigation lead at apl. sorry, at nasa's jet propulsion laboratory. we are going to hear some opening remarks and then take questions from the media that we have in the room and dialed in. we will try to answer as many questions as we have in a limited time. ed and lena, how are you feeling now? >> great. and relieved. [laughter] >> i definitely feel relieved. this is absolutely wonderful to do something this amazing and we are so excited to be done. [laughter] we have worked on this mission

we're looking at the smaller dot that is dimorphos. dimorphos is the one it's going to slam into. it's about the size i understand of egypt's great pyramid. the spacecraft is equivalent to the size of a refrigerator. and you're in the vast vacuum of space here. how amazing is it that nasa could pull this off? >> this is incredibly amazing. this is really the first time, erin, that we are using things that we've talked about in science fiction, you know, things that we see in movies, and in tv series that is really designed to protect the environment and the planet itself. you know, you go back to the time of the dinosaurs, and you -- the theory is that dinosaurs were made extinct because of an asteroid or a series of asteroids hitting the earth. there was a case in russia in the early late 19th century, early 20th century where we actually had an asteroid hit siberia that resulted in a lot of destruction of territory there. luckily not very populated territory, but still, the danger is definitely there. and it's something that even though the probability is low, it's one of those

jwse and missions are concentrating on didymus and dimorphos. in the next couple of months we will get confirmation of exact period change we made. it will not be tomorrow, i am sorry. we might see some images coming up in the next day or two. the little cubesat should have flown by now and taken images of the plume that we we created. we will see that data come in the next couple of days and over the next few months we will get more information from the investigation team on what period change we made. that is the number two goal. number one, hit the asteroid. number two, measure the change and characterize how much ejector we put out. >> to clarify, about two months? >> yes. i would say a couple of months for the full quantitative answer. some things will likely come out in days or weeks to say this is what the observatory saw. i know they plan to download images in the next few days so we will get some parts of the answer soon but i would say the quantitative full answer, a couple of months. >> and should all earthlings sleep a little easier

its entire mission is to ram into dimorphos. the result is hoped a gentle nudge push and the asteroid on a new path. over many years the change in trajectory will grow larger. while dimorphos itself is not in course to collide with earth, space rocks hit the planet all the time. the big ones can change the course of life on earth. 65 million years ago, huge object crashed near the yucatan peninsula, causing global devastation. scientists believe the impact is directly linked to the extinction of the dinosaurs. getting rid of t-rex was a good thing for us mammals, but another collision of the same magnitude will not be. it could destroy us all. so the international consortium behind dart hopes to defend the earth from potential catastrophe by combining observations to identify asteroid threats decades ahead of time along with the ability to knock them off their collision course. >> there are no known asteroid threats, but maybe we will have technology to prevent them. reporter: the information gleaned from the test will hopefully

dimorphos is not headed toward earth it's just a test. is the first time in human history that we've actually set out to change the orbit of a natural object in space. miles: lindley johnson is nasa's planetary defense officer. lindley: the orbit of an object is determineby the velocity at which it is orbiting. so if you just, you know, shave a hair, you know, less than 1% off of that speed, you've changed the orbit and, you know, forever altered where that object will be in space in the future. miles: our planet gets grazed and hit by asteroids all the time, most offer harmless thrills for stargazers, but the bigger ones are a different story. in 2013, a 60 foot asteroid exploded about a hundred thousand feet over chelyabinsk, russia. about 1500 were injured by shattering glass. over the epochs, much bigg asteroids have triggered mass extinctions, including most infamously the dinosaurs 65 million years ago. planetary scientist nancy chabot 's coordination lead for dart. is it accurate to say it's inevitable over the course of time that

the crash gave dimorphos a kick to change its speed and alter its orbit.an asteroid, you need to know where it is. the biggest ones, more than a kilometre, about half a mile across, could cause global devastation, like the asteroid that wiped out the dinosaurs. we've spotted most of these, and none are heading for earth. but even the small ones pose some risk. a 20—metre wide space rock — about 65 feet — exploded over russia over russia in 2013, injuring hundreds, but very few around this size are being tracked. but it's the ones in between that are causing concern. a150 metre wide space rock — about 500 feet — could obliterate a whole city, and we've only located 40% of these. astronomers work out these numbers by carrying out surveys of small areas and finding every asteroid there. they then extrapolate this across the whole sky to calculate the asteroid population overall. you can't do anything about the asteroids if you don't know where they are. and so this is where dart comes in. it's something that you would want to have this knowledge of where the

a larger space rock called didymos is orbited by a smaller space rock called dimorphos. at 111,000 miles an hour crashes into dimorphos, giving the asteroid a kick. this changes its speed byjust a fraction, about a millimetre per second. but this is enough to alter its orbit. and scientists can monitor this from earth to see if it has worked. thanks to the spacecraft�*s on—board cameras, we will get to watch the crash as it happens. this is part of the reason that we need to move beyond doing tests in the lab for asteroid deflection, or running models on our computers. but doing this on an actual asteroid of the relevant size, to see how these small little worlds mainly react to a deflection technique like this. the dart mission will be the first step in finding a solution, helping us to protect our planet should a real threat come our way. rebecca morelle, bbc news. time for a look at the weather. here's matt taylor. i'm going to spite with space because tonightjupiter will be its closest to earth since 1963. if you have binoculars or telescope a good night to get the b

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

amy: astronomers will observe dimorphos and the much larger asteroid it orbits to measure how dart altered their path around the sun. impacts from comets and asteroids have been described as the only preventable natural disasters, though the odds of a catastrophic impact in any given year are remote. this comes amid warnings from nasa over the ongoing threat of unnatural disasters. peter kalamus, a climate scientist at nasa's jet propulsion laboratory, tweeted -- "it's great that nasa is testing the ability to deflect an asteroid or comet if necessary, but the actual clear and present danger to humanity is of course earth breakdown from burning fossil fuels. #dontlookup" in mississippi, about 1000 homes and businesses are once again under boil water orders after construction crews accidentally severed a water line on monday, leading to a drop in pressure. it is the latest of about 300 boil water notices issued in jackson over the past two years, including the city what advisory lasting 40 days that began in august when torrential rains flooded jackson's main water treatment plant. on monda

amy: astronomers will observe dimorphos and the much larger asteroid it orbits to see how dart deflectedr paths through space. nasa hopes to prove that, with enough warning, it will be able to nudge an earth-bound comet or asteroid off course, averting a catastrophe. the earth is constantly peppered by small meteorites that fall harmlessly into the ocean or gush over remote areas, but rarely much larger rocks fall on human settlements. on february 15, 2013, an asteroid the size of a house entered the atmosphere above chelyabinsk, russia, a city of more than one million people. the sulting meteor explod th the force of a nuclear bomb 14 miles ave the gund, leaving a brilliant stak of firecross the rning sky. the meteor's shock wave shattered windows, blew doors off hinges, and injured more than 1600 people, mostly from broken glass. no deaths were rorted. nasa hopes to one day be able to prevent a similar -- or much worse -- disaster. although the odds of a catastrophic impact remain vanishingly small. as the dart mission draws the world's attention to threats from outer space, nasa scien
