and with earth science as mentioned earlier to understand the earth with space to watch the changing environment. >> the remarks started with the greeks and the planets in the priorities should be to orbit one of the nearest stars and that is a problem but that is something that america is leading the way * shade is not developed in any other country. >> we want to search for faraway planets but we also want to make sure we do the work here on earth correctly nasa has been a leader in climate science to help us understand and to give us the most up to date data with mission with grace. so associate administrator if nasa's earth science research important to understand threat like climate science mac it is a very important program. your lien program that we have is very strong. with an increasing number of spacecraft last time i counted was 17. with all missions in orbit and yes i do believe that this very important program is complementary to the government and beyond is important. >> will you make a commitment to this committee that will remain a priority for nasa in the years ahead

the goal is to find a true earth when -- earth twin. whose environment we can understand in the context of the search for life. next way a massive, bright star like the sun. the difference in brightness is one part in 10 billion, so we need to wait to block out the sunlight to see the planet directly. the w first chronograph instrument is the first high contrast space-based chronograph, blocking out starlight to study exoplanets. it won't be able to reach down to find other planets like earth. it can study about a dozen giant exoplanets already known to exist. it is critical to the demonstration to abide down risk to the future, for more ambitious missions already under study. we have a technique to find earth with a modest sized telescope, tens of meters in diameter with its own spacecraft. it would fly its own information tens of thousands of kilometers away. the starship does all the hard work of blocking the light, and the technical reasons behind that are why the starship -- star shade can already find earth analogs, building upon

by comparing the planet of earth to other planets -- climate of earth to other planets, it has really helped us understand what's happening here. we first identify the ozone hole on earth, a scientist looking at venus came back and looked at the earth, and that was how the problem was first identified. >> that's how mario did that? interesting. >> another example that comes to mind, studying ice planets and looking at glaciers. you are looking at the same physics. the remote-sensing technologies, ice-sat 2 is launching in september. we use many of the same remote-sensing technologies when we go visit planets in our own solar system as we do looking back on earth. science, we see in you look at one example, you don't fully understand what's going on. we have understood the earth much better, understood processes on the earth by first observing things happening on venus, on mars, elsewhere. and now when we look at extra-solar planetary systems, we are understanding our solar system better, as we see our solar system as but one example of many. and stepping back, getting this bigger pict

we understood the earth much better. and as mentioned, we understood the processes on th the earth by chris deserving things that are happening on venus and mars and elsewhere. and now, when we look at extrasolar planetary systems, we are understanding our solar some better because we now see our solar system as both one example of many interesting back and getting the sticker picture and those physical processes makes us rethink the way that we think about the earth. hispanic medical imaging is one of your old familiar with. in astronomy we have to do the same thing, process the data and medical imaging for making big leaps forward. we built a small telescope and what it does in th the technoloy isn't complained precisely 100 times more precisely than any time in its category. for the people most interested thethey come from optimal communication and a way to pack more information and that is probably where the technology will end up being used. before i took this job has been developed in the space into spay including

we talk about rare earth metals on the earth. those are not earth metals at all. those are asteroid impacts from a billion years ago or more. the moon has the same marks on the moon, but it does not have active geology. the hydrosphere there is much less active than earth can which means there could be massive deposits of rare earth metals, but that could be on the moon as well. we need to prospect the moon and understand it. there is a lot we don't know. from 1969 until 2008, most people believed that the moon was bone dry. 2008, the indians made a discovery there is water ice. 2009, nasa discovers that there is hundreds of billions of tons of water ice. that should have changed our perspective immediately, going back to the moon with a sustainable architecture to do the science, discovery, and do more than we have ever done before. the architecture not only gets us to the equatorial regions, which is what apollo did, it gets us to more parts of the moon than we have been to before, so we can make those discoveries. we should know more about the moon today than w

all planetary science begins on earth. based on our understanding of how life arose your it requires long-standing, stable bodies of liquid water. life evolve rapidly once conditions stabilized on the early earth which chemical signatures indicate was 3.8 billion years ago. it is highly adaptable, astro biologists found life in extreme environments like volcanic lakes, sulfur springs in the top of the stratosphere. microbes have been found under high level of radiation or consuming toxic chemicals. we find life on earth nearly everywhere we look for it. given the commonality of conditions here and elsewhere in the solar system is highly unlikely that life is unique to our planet. we know the building blocks, amino acids, are ubiquitous in the solar system, found in comets, asteroids and interstellar clouds. the next step is to identify environments habitable to microbial life like those on the early earth with liquid water, a source of nutrients and a source of energy. within the icy moons of the outer solar system we have

here on earth and in space. peace will always seek in space as on the earth but history profs that peace only comes through strength. the united states space force will be that strength in the years ahead. [applause] >> now, the report the department of defense will elease today that secretary mattis just referenced represents a critical step the space blishing force as the sixth branch of our armed forces. actions we'llfour take to evolve our space capabilities and they're built on the lessons of the past. we all remember it will hard esson learned in the early desert one tragic took place. eight american patriots fell in while rescuing fellow person americans being held hostage in iran. wake of that failed mission, america resolved to nsure that our joint war fighters would always have the training coordination and leadership they needed to accomplish their missions. the steps that our nation took in the years that followed creation way for the of the united states special command.ns since that time, this vita

across the world the problem is that if we are looking for evidence of a ticking point the earth has to change to a new state will see the full evidence once this happens and we. are going to be on that if you look at a period of thirty years on the increase in the frequency of extreme phenomena is connected to climate change give me the scheme i think is going to get so if we start to see some telltale signs will be getting zapped and we need to take that really seriously. also coming up remembering europe's first armed conflict of the twenty first century the war between russia and georgia ten years ago left an unresolved border running right through people's law. better shots and . see if you cross the line they can seize you find your person. then a home for animals across they take them. in the living boundary line has swallowed some of india's property in the past now he's determined to stand his ground. we begin the day with severe weather across the globe and they warning that climate change could be more unpredictable and inhospitable than we have been led to believe climate

well what we did is we sort of said well listen it's nice that politicians have decided that the earth will be two degrees warmer than it was in the pre-industrial and sort of assume that it'll just stay at that temperature who's a back at the earth's history and it turns out it's never had a stable period of long a long period where the temperature was stable at about two degrees above pre-industrial so what that told us is that there may be other processes in the earth's system that when you get to be two degrees warmer could keep pushing the temperature up until you got around four to five degrees as has happened in the past so we started searching for those processes and we didn't identify anything new all of these processes have been identified before but we looked at was the interactions between these processes we're talking processes like the melting of ice the melting of permafrost the changing biological conditions in the ocean the changing chemistry of the ocean and then we're talking tipping points as well the melting of the greenland sea ice the the or the arctic sea ice an

a situation where the earth was what we call hothouse earth which is four to five degrees warmer and that would not only mean ten to sixty meters of sea level rise it would also mean heat waves like you can't imagine the areas of the up the earth where humans would be unable to live and certainly very much changed and reduced area where we could produce food massive storms wildfires people moving away from regions where they they can't produce food or can't survive the temperatures though potential political conflicts it would also the the animals and the plants that we know today many of them would go extinct so it would be an entirely entirely different world than the one we know if we did actually go to a hot house and and just to be clear this is not like these things you hear on mainstream media a lot of a dime analysis of data as in say the nineteenth century you really are really looking at ice sheets and data that going on now in light of what we're trying to do is understand the earth as a system as a complex system and analyze its behavior as a complex system and when i tal

the searing temperatures calm as a new study warns that the earth could be entering a period in which its ecosystems are irreversibly disrupted. it's been more than fifty years since the state of new south wales in australia has seen a drought like this farmers pray for rain as their crops and livestock die some are forced to shoot starving cattle well others face the prospect of having to simply abandon their land. on the other side of the world a similar story the french of those mountains are simply too dry about half of this farmer's corn crop has already died in the us record temperatures are fueling the worst wildfire in california history the twin blazes dubbed the mendo sea no complex have exploded to cover an area the size of los angeles in less than two weeks. scenes like this are likely to become the new normal according to an international research team's latest study they call the trend hot house earth i said. it's when the climate is much warmer than it is today three to four degrees than it already is four to five degrees warmer than in the pre-industrial climate. inter

do our domination of the earth has had dramatic consequences human activity is altering the earth's ecosystems and impacting the climate. tens of thousands of species are threatened with extinction eventually she kind itself may be on the endangered list . yet we steadfastly ignore the warning signs as if climate change were a fiction one big question is why you would societies aren't acting for rapidly to counter some of the negative changes we're making in the earth like rapid climate change. societies have been threatened by climate change before. some found solutions. others come out just. the challenge we face today is the same as in the past can we adapt. will climate change force us to reevaluate our way of life. whatever solution we use will require political courage because it will require change. phoenix the capital of the us state of arizona is symptomatic of humankind's over exploitation of natural resources. it's a modern city like many others but there's one big difference it's located in the middle of a desert. in one nine hundred fifty the popular impossible to live under the b

so i'll be entering the eve of hothouse earth. a climate policy analysts from the environment and development and geo german watch is with me welcome to you now we see a heatwave not to see in europe but many other parts of the world also facing very hot temperatures what explains this well as you're saying this is something we're really seeing across the globe in our research shows that it's mainly the poorest countries that are hit hardest but right now we're also seeing it across the entire northern hemisphere pretty much what is happening is that we have a very stable warm weather condition right now it doesn't change much it heats up more and what is little rain and that is because the jet stream is very weak right now that's the circulation in the atmosphere that usually brings cold wind from the polar regions to other parts of the world such as europe and that has almost stopped and that is actually linked to manmade climate change ok but in this report we had scientists talk about the earth heading towards a hothouse spiri

is the idea that aliens have visited earth and in of itself a conspiracy theory? >> i don't believe so. if you take into consideration the fact we are trying to go to mars, we would technically be alien life there. the fact that another life form say has become intelligent enough to do space travel is not really a conspiracy theory. >> it seems fair. >> i guess it depends on how you define the scope of a conspiracy theory. take an entire species collaborate together to land themselves on another planet. i don't really think it's a conspiracy. >> it seems reasonable. it seems odd to indict the entire planet of forever for wanting to come and visit. even if we are going to arguably , maybe we can consider it a conspiracy -- conspiracy theory, it's a conspiracy of aliens. it is not what we tend to talk about when we talk about ufo conspiracy theories, when we talk about alien conspiracy theories. those are theories that include an element of human complicity, usually of government complicity. these ideas that there are not only aliens visiting earth, but that the sta

international climate targets aim to limit the earth's warming to two degrees celsius but scientists now think even that is too high setting in motion processes which could create a domino effect such as glacial melting researchers argue that without putting in place specific human made climate protections the seas could rise but up to sixty metres so how to curb greenhouse gas emissions scientists say we need to cut industrial carbon travel less by plane and car and eat less meat they say already the earth is on the brink of irreversible warming with severe effects like those in australia the government there has announced a multi-million dollar relief package for farmers but with dry conditions forecast to continue that may not be enough. yes severe weather around the world to talk about that i'm joined now by lutes by sure he is a climate policy analyst with the environment and development in geo german watch what is going to have you on the show you know people around the world are asking droughts wildfires heat waves are all of these connected in some way and are they all connec

america will always seek peace in space as on the earth. but history proves that peace only comes through strength. and in the realm of outer space, the united states space force will be that strength in the years ahead. [applause] now, the report the department of defense will release today, that secretary mattis just referenced, represents a critical step toward establishing the space force as the sixth branch of our armed forces. it actually identifies four actions that we will take to evolve our space capabilities, and they are built on the lessons of the past. we all remember the hard lesson learned in the early 1980's, as the tragic debacle of desert one took place. eight american patriots fell in the line of duty while trying to rescue their fellow americans who were being held hostage in iran. in the wake of that failed mission, america resolved to ensure that our joint warfighters would always have the training, coordination, and leadership they needed to accomplish their missions. and the steps that our nation took in the years th

our nation's armed forces have always been the vanguard of advancing american leadership here on earth and beyond. the space force is the next and natural evolution of american military strength. the first american rockets in space were launched by our military. the first american satellites to orbit the earth were on reconnaissance missions peering behind the iron curtain. the first americans to step forward to venture into the unknown were the world's greatest aviators and test pilots from the navy, the air force and the marine corps. and the next generation of americans the confront the emerging threats and the boundless expanse of space will be wearing the uniform of the united states of the america as well. [applause] finish -- i'll promise you your commander in chief is going to continue to work tirelessly towards this goal, and we expect you all to do the same. to all the men and women of this department, this is moment, now's the time to the act quickly using all the tools as your disposal to lead our nation forward with president trump's vision to meet the challenges that lie

i said what house earth is when the earth when the climate is much warmer than it is today three to four degrees warmer than it already is four to five degrees warmer than in the pre-industrial climate yankee. climate targets him to limit the earth's warming to two degrees celsius but scientists now think that that is even too high setting in motion processes that have both more extreme and irreversible such as glacial melting once they're gone the sun's heat stops getting reflected and starts getting absorbed speeding up global warming the potsdam institute which specializes in climate research argues that without putting in place pacific human made climate protections the seas could rise by up to sixty metres. and that's you know this is something long term but of course in the next few decades and by the end of the century these are will have significantly negative impact on cities which are often on the coastlines on. climate scientists say we need to address clean cut industrial greenhouse gas emissions travelling less by plane or by car and eating less meat as well. in the sho

how many of us believe that aliens have visited earth? sergio, the only man with the strength of his convictions. i appreciate that. so here is a question. is the idea that aliens have visited earth in and of itself a conspiracy theory? sergio? >> i don't believe so. >> no. why not? >> well, i mean, if you take into consideration the fact that we're trying to go to mars, we would technically be alien life there. so the fact that another life form, say, that has become intelligent enough to do space travel, visits another planet isn't really a conspiracy theory. >> seems fair. >> i guess it depends on how you define the scope of a conspiracy theory, because it takes an entire species more or less collaborating together to land themselves on another planet. so, there's an entire race working together considered a conspiracy? i wouldn't really think so. >> that seems reasonable. it seems a little odd to indict the entire planet of wherever for wanting to come and visit. even if we are going to say arguably, maybe we could consider it a consp

they call the trend hothouse earth. >> hothouse earth is when the earth, the climate, is much warmer than it is today. three to four degrees warmer than it already is, four to five degrees warmer than in the preindustrial climate. reporter: international climate targets aimed to limit the earth's warming to two degrees celsius. but scientists now think even that is too high, setting into motion processes which c could result in a domino effect such as glacial melting. researchers argue that without putting in place specific human-made climate protections, the seas could rise by up to 60 meters. so how to o curb greenhoususe gs emissions? scientists say we need to cut induststrial carbon, travel less by spy plane and car, and eat less meat. they say already earth is on the brink of irreversible warming with severe effects like those in australia. the government there has announced a multimillion relief package for farmers, but with dry conditions forecast to continue, that may not be enough. brent: severe weather around the world. to talk about that i'm joined by a climate oig -- poli

the flat earth is huge on this. to hide the fact that the earth is flat and that we're sending satellites up that aren't going anywhere but it's all part of a conspiracy to cover it up, oftentimes leads to magical and supernatural. you reach a point where the evidence is going to begin to collapse and what you see underneath that is clearly a religious or magical sense that this can happen because the rules of reality are not the ones by which we're having this discussion. and this sense of no coincidences. when someone introduces something and says, isn't it weird that this data point is there, right? isn't it weird? i'm sure no one knows better than me that there are data points of the entire 9/11 that everyone seems to go, yes, that's weird. like that's a strange thing that happened that way. but the conspiracy theorist, there's no room for that. this is all a system in which things are being done for particular reasons and there are no coincidences. again, as we said, 9/11 is an inside job brings this up all the

we estimate she is about 200,000 miles away from the earth. has solar panels are out so we are power positive on the spacecraft. the cooling system which is critical for us to keep the solar panels nice and cool during the orbit, that system is active and we have the right attitude and she is on target for venus. as she makes this journey towards the sun, will we see any other sites, will there be any other data we can receive along the journey or is itjust about the sun? it is all about the solar wind. the next couple of weeks we are incredibly busyjust getting this spacecraft operational on orbit, getting instruments deployed and powered up and everything ready. we will be focused on that for the first 12, 13 weeks and then we make our first swing through the solar corona. once we have done that and the instruments are operating, we will have them on almost all the time unless we are downloading data. we will have them all the way around venus and into the sun's corona. there must be a lot of confidence because these things don't come cheap,

but the bible talks about the way that earth is set up. it has pillars set in, there's a depth underneath, that's where the -- swims, one of the things about flat earth that seems so ridiculous, we know there's a flat earth because we have a picture of it. or if the earth was flat, gravity would work in a horribly strange way in which trees on the edge would all point to the center because of where the gravity would be. we think, we have not worked out the math on the flat earth gravity system, but underneath that is about biblical literalism and the bible being true. and having a debate over whether how satellites would work is not nearly as important as the idea that the bible is true and the bible tells me this. and the reason this is being covered up is because modern american society hates the bible and wants to convince people the bible isn't true with the idea of a round earth. right? so the debate over the flat earth seems like the easiest debate in the world to win, that this is literally going to take no time. but underneath it i

i've often said you can do it for 9/11 and the flat earth. if it's flat earth. you can say let's get a sense of how many people have to be in on the earth being flat. that number as you might imagine, is mind bendingly large. then the answer is why. if the take away is, because they don't want evidence of a god created world, first of all arguments of a god created world are doing really fine in american culture. it's not like they're ignored. when will this conspiracy would have had to start which would have been a lot earlier than the turn to secularity. you would have had to start this in the 18th. nineteenth century in which religion was unquestionly the center of american life. and the argument that the earth was flat. many churches like the catholic church would have been like hooray. because if this is evidence of a god created world they are certainly someone who would want that evidence. there's 9/11. when you think about it the 9/11 plot is really complicated. it involves a lot of lose ends and a lot of exposure and a lot of people being involved. we'r

we have pioneered the technology to leverage american power in space here on earth. and give our war fighters the intelligence that they need and give our intelligence community the information they need to maintain a strategic advantage. wherever our war fighters are operating. across this department and our intelligence agency, there are literally tens of thousands of military personnel, civilians and contractors operating and supporting our space systems. and together, they're the eyes and ears of america's war fighters around the globe. they do a remarkable job. i have seen their work first hand. i traveled across the country to meet with the men and women who are fighting for america's future in space in my first year and a half on this job. from the airmen of the 50th space wing at an air force base whose fleet of surveillance navigation and communication satellites increase the agility, precision and effectiveness of our armed forces, to the engineers of the missile defense agency at red stone arsenal in alabama who are forging the next generation of rockets t

i wondered what the practical uses of what they find out could be back here on earth. lots of it is about protecting ourselves from these solar flares, solar energy that the sun emits. the sun is very dangerous to humans. the more we understand about it the more we are able to protect ourselves on daily basis. when you look at the different spatial missions that have gone before it, where does this one set in terms of the importance and excitement around it? —— different space missions. when eugene parker first theorised the existence of solar wind, it was laughed at by his peers. in 1962, a spacecraft detected them. it's been this long journey since then, since 1962. parker wrote the paper in 1958. it's been this half—century long journey of discovery to this mission to understand this phenomenon more. when we saw that launch happen, what was that telling us in terms of the technology that has been developed and how long it's taken to get to this point? the spatial missions can last anywhere up to a decade in development, but i was there last night and the delta

things like the comets and asteroids that could threaten the earth as they did the dinosaurs and it could be the case that military space essence could be used to deflect or destroy threats to the entire earth and that given the fact that we've had several near near approaches and near misses from fairly large asteroids that is one strategic threat to the earth that can't be ignored it's certainly very frightening i'm sure now experts in china the u.s. and other countries are probably looking at ways to speed up the space race but we have reached the end of our programs of thank you everybody on a very maggie and tangan and maurice jones and thank you too for watching you can see the program again any time by visiting our website al-jazeera dot com. and for further discussion go to our facebook page that's facebook dot com forward slash a.j. inside story you can also join the conversation on twitter our handle is at a.j. inside story from a height of the honey than the whole team here in the by for now. travel often. by tranquil gotos and purple forests near prague model. looks of o

is the claim that the earth is 6000 years old compatible with the claim that the earth is 4.6 billion years old? no. one of them is wrong. and one of them is at least not long, close to being right or true in the scientific sense. it's like when richard dawson says 12 opposite points of view are expressed with equal intensity, the truth is not necessarily exactly halfway between them. it is possible for one side to be simply wrong.the answer is not add up 6000+4.6 billion years and divide by 2. the point of science and reason is to get us closer to the truth. truth with a small tea. one of my favorite essays on this was called the relativity of wrong. when people thought the earth was flat, they were wrong. when people thought the earth was spherical, they were wrong. the earth is an oblate - - on the equator from pole to pole. if you think thinking the earth is fear coal is just as honest thinking the earth is flat and you are more wrong than both of them combined. we made progress in understanding the world around us. i should point out, we don't believe in science and reason. they'
