now is the earth really moving towards the moon? we on earth think, no, no, no, no. the moon is moving toward the earth. there's a force on the earth, i mean, there's a gravitational force between the earth and the moon that pulls the moon this way, right? why don't the moon crash? because it's moving like that. so as it's being pulled instead of coming over here, it's moving like this. it doesn't get to here, it gets to here. it's being pulled like that, instead of getting here, it gets to here. and so it gets pulled around and around and around in a circle, but guess what the direction of the acceleration is as it's going around and around and around the circle? it's toward the center of the earth, see? so we think of the moon as going around and around and around us like i take a rock in the end of a string and i go whirl it around, around, around. we talked about the idea that the force along the string is acting toward me, right? the rock is really accelerating toward me. if it weren't it would go somewhere else, but it keeps pointing toward me all that time, hu

we all are earth-based. we all are earth-based. it is the planet we live on, and to begin to see and claim the earth as sacred, reclaim and recognize the earth as sacred, doesn't need to conflict with any other spiritual belief. in fact, ecologically, it's becoming essential to create a sustaining spiritual movement. just as earlier religious movements came up with laws 4,000, 6,000, 2,000 years ago, those mandates were to assure life - they were all life-sustaining. and today, we're needing to change a consciousness about what we value spiritually, to create a true life-sustaining paradigm, and i think that that is that call to earth-based spirituality. whether it comes through matthew fox in the catholic church, or through people who want to step out and use more radical terminology, it is our times, and a spirituality that is beginning to address the needs of these times. >> i think edward hays is another catholic priest who speaks comfortably in the same language. >> and thomas berry. >> yes. >> i also know that starhawk does -

most of the water on earth probably came from comets that impacted on the earth in its early history. and we know something you just said stood out to me, the closest it's coming, it's passing by now? >> yeah, this is at 7:09. my question to you, lawrence, there's obviously no danger, but it is unsettling for people because they were detected only days ago whether it be by universities or by scientists. do you think there's a need for more asteroid detection? >> oh, yeah, i think it's very important that we fund -- and we are funding these near earth object detection systems. we need to do it. it doesn't cost a lot. and it's important for us because as i say if this object hit the earth would cause a lot of hesitation. we might need to do something about it. but in some sense, we're suffering from embarrassment of riches. it's true that this was only detected nine days ago, but a decade ago, we probably wouldn't have detected it at all and wouldn't have worried about it. so we're getting better and able to see more objects and learning about -- there's lots of stuff going around and c

close to the earth. this happens all the time. disasters come close to the earth will be attractive targets for exploration, and robots in the coming is to associate an asteroid the thought of an impact trajectory, i'm reminded there's a 30% chance there is a five-megaton or impact that will hit as this century. so should we find one, i believe that humanity will come together to prevent this but we were user space technology to nudge the astro to prevent it from hitting the earth. and i think that will be a watershed moment in human history. so thank you very much. >> and we want to get into how you're going to nudge it away. and we'll get into that. mr. dalbello. >> thank you, mr. chairman. santa cruz, it's a pleasure to be here today. talk about the issues of space risks and how that relates to the commercial sector. the commercial operators who are earning their living day-to-day in space. we've been in this business for about 50 years. we are currently flying about 70 satellites. so we're pretty sum

and then we have a nation buster which is going to come grazing past the earth and may even hit the eartht's called the asteroid apofet. it's ten times bigger than the asteroid that scimed the earth last week. >> stephen: what do you mean may hit? what is the -- do the math. [ laughter ] what is the math on that one? >> well, first it's going to skim by the earth in 2029 and it's going to graze the atmosphere. that's the question mark. we don't know how much friction it's going to encounter. that cannot be factored relyibly. when it grazes the atmosphere on the second pass in 2036 there's a window of opportunity where the thing could actually hit the earth even though it's still very small. >> stephen: because of the friction it encounters on 2029. >> that's right in the second pass. >> stephen: can we lubricate the earth in some way so there's not so much friction? [cheers and applause] and just duz -- [cheers and applause] >> the russians have taken this seriously. >> stephen: of course, they would. they almost got tagged. >> they said we have to maintain serious propals. maybe in 2029

threat to life on earth. however, the potential consequences of a significant impact or potentially great indeed. it is prescribed in the national they will pursue, tracking shared drives objects to reduce the risk of harm to humans from an impact on our planet. nasa is developing new details and capabilities including the multipurpose crew vehicles on the space launch system of the solar system beyond orbit as is stated in his 2010 speech at the kennedy space center, nasa's intention is to send astronauts for the first time in history and nasa is working to accomplish this mission by 2025. nasa leads the world in the detection of characterization and is responsible for 90% of all known neos. there should be a chart coming up soon. as shown in this graphic, the cumulative discovery of asteroids picked up dramatically with the start of the spaceguard program and the number of known asteroids has grown from a few hundred to 10,015 years and it's not insignificant that it goes almost asymptotic when you look at

those were times of earth-based religions and earth-based spirituality. and in the most simple sense, the clan did not need to be inspired to do ritual and magical work, for our life depended on things like harvest and weather and growing and hunts. and today, metaphorically, it still is dependent on our interrelationship. so at that time, it was easy to inspire the clan to work magically together - because we cared about each other, and we knew that how we ate, and how we would survive the winter, was based on our magic, our connections with the god or the world or the goddess - our life force itself. so what i would like us to do is just pretend that you can speak directly to the wind, to the fire, to the water, to the earth, and as i ask you to personify those elements, i'm not asking you to believe that they are humanized, but i'm asking all of us to recognize that one of the ways we enable ourselves to destroy things is to dehumanize them. so if the air could listen to you, if the water could answer you, if the fire would come to your call, what the

we have to look to extraterrestrial resources to support our growing civilization here on earth. as it's very actually we do what's the next step for you about. well that's. the next step is a baby step what we're talking about is the first private sector company to reach the moon and that's the first goal of minix presses to land in them with a robot where we're still a long way from getting even back there with humans one of the things that linux press is doing is we're competing with something called the google x. prize google let's put up a forest of thirty million dollars for the first product company to reach in the sun back high definition photography and video and that's a very exciting innovative incentive for us it's not the whole reason little in the forest we see a reason to go in continuing. the business of delivering science to commercial sales to the moment we're basically building a railroad earth. much like opening up a new frontier our first goal is a very modest a first goals of just to land on the moon then begin some process acting and then bring some materia

i think it as we increase our understanding of near earth objects and their potential the earth that congress to take the subject seriously in that regard, this committee has taken leadership roles on these issues, dating the to the efforts of former chairman george brown junior in the early 1990s. that is a time when references to killer asteroids could lead to giggles and eye rolling. since then, members on both sides of the aisle, including former chairman hall and giffords have taken an active and productive interest in this topic and progress has been made. that today's hearing will provide us with a good update on the federal government efforts to detect, monitor, and mitigate such .azardous near earth objects much has been accomplished over the last decade and i look forward to hearing about those efforts. in addition i would like to know if there are additional steps we should be taking as a an expandedh detection program or international collaborations of such measures. where we have much to discuss today and distinguished panel to help us in oversight. i look forward to hea

fifty million years later dinosaurs began to roam the earth and another period of stability began on earth and on the two continents was geologists today called noor asia and goal goal gondwanaland the triassic jurassic cretaceous periods known together as the mezzo of period came to an end sixty five million years ago when a meteor asteroid struck the earth causing the dinosaurs to go extinct during the mesozoic period the planet underwent another period geological on rest and the two continents broken is smaller pieces of land to create the seven continents that exist today. at the same time mountains were created as these cons drifted into each other and plant matter that had been buried underground millions of years before it was pushed even further into the ground and subject to great pressure that pressure and millions of years of time converted all that now underground plant matter into oil coal and natural gas which brings us to nine thousand nine hundred years ago when humans for in europe and asia first discovered coal beneath the surface of the earth and began to burn the

the earth was one of many celestial bodies, all of which obeyed the same impartial laws.t the same time europeans learned of that revelation, the discovery of the americas and the exploration of the far east revealed that europe wasn't the center of the world. inhis time of spiritual crisis provoked by the explosion of knowledge, artists sought new ways of seeing and understanding. the out-thrust left arm of the disciple startled and astonished its first viewers in 1600. it breaks into the space in which we stand. the naturalism of this painting of christ at emmaus by michelangelo merisi, known as caravaggio, was unprecedented. its intention is to convince us we're participants in this astonishing event, god's presence in the flesh. we may no longer regard the earth as unique, caravaggio seems be saying, but god has dwelt amongst us. divinity and sanctity are to be found in our midst. caravaggio went out into rome's streets and put people he found there in his paintings. he came to rome from northern italy in the last decade of the 16th century. a strange, violent, driven

you know why the earth's round? you know why the planets are round? because if there are great, big cubes the corners could be pulled in by gravity, gravity pulls everything in until it gets round. the whole universe, it turns out the idea of gravity underlies our thinking about the universe. you guys hear about the big bang theory? the idea that about 14 to 20 billion years ago the whole universe was in one point and exploded out, all flying out. let's look at that in terms of the gravity bit here. let's suppose, here's the big bang and all these pieces are flying. now let's suppose that we knock the whole universe into four halves just to make the thinking easy. if we can understand the simple examples then maybe we can deal with complexities. here's part of the universe here, here's part of the universe here, part of the universe here and all are flying apart. there's nothing else that exist just this and there they go. any force of attraction between these phases? how many say, yeah? it turns out this would be attracted to here, this would be attr
