rachel. don, first to you. what do you think of this scene? i am completely jazzed by this. and the first thing i would like to say as a scientist, i would like to congratulate the technical and scientific staff at nasa and jpl. great job. and what s just happened? we know it landed on mars. tell me more. well, now the next step is to shake out the equipment, deploy the solar panels. then there are three different missions that insight wi will. one is to test the wobble of mars rotation, to find out something about the core of mars. another one will be to deploy a very sensitive seismograph to look for mars quakes and when meteors hit mars, to find out more about its interior. and finally, and perhaps the most exciting, is to drill down 16 feet underground to actually take the temperature of the planet. and that will teach us something
as they did back in 1998 and 99, mars polo lander, when they didn t get that signal back. those memories are seared in the collective consciousness at jpl. they ve had great moments and they ve had moments of absolute agony and defeat, as well. we want to avoid the agony and we would like a repeat of the high fives from curiosity in 2012. and rachel we, for people who a just tuning in and are like, why are they talking about mars and this insight, what is the purpose of it all? there have been many missions to mars before. and to highlight how difficult this is, pulling off either landing a lander or a rover or an orbiter, bringing an orbiter to mars, more than half of the missions have actually failed. so there s about a 40% chance of success here. so, you know, this is incredibly difficult. space is hard. i just want to highlight that. but most missions to mars have been about studying the atmosphere or the surface. it hasn t really been about getting to the core, literally,
meteor. if it goes more shallow, it will bounce off the atmosphere. and while it s falling, it s essentially, a meteor, falling into the martian atmosphere. the martian atmosphere is very thin, and that s what makes landing on mars so very difficult. it s 1% the amount of air that we have on earth, and that makes it difficult to slow down. let me once it s about halfway down can i hit pause on the science for a second, because i want to explain to people, and miles, let me go to you. we have another box on the screen, and i m assuming, this is pasadena. is this the jpl lab? are these the folks that are steering this thing for lack of a better word? well, at this point, they re just going for the ride, brooke. as he pointed out, this is an automated thing. the people in that room, they are the river boat gamblers of science, brooke. they put their chips on the table, they spend a decade or so working on a mission and it all comes down to 6 1/2 minutes and it s either a great

the telescope will begin live tracking of the flyby tonight at 9:00 eastern time, which you can watch online. this is a very large asteroid, nearly 900 feet long, as big as three football fields but also as big as intrepid aircraft carrier that sits on the west side of manhattan. imagine something that size slamming into earth. the media that exploded over russia last year was just 30 meters in diameter. that explosion carried more energy than a large atomic bomb. bill: you had the story today, we will be here tomorrow. where are we in identifying the near earth objects posing a threat? it is a non-stop program. among the scientific and astronomical community out of jpl in california, they have near earth object program, other
