eighth two thousand and fourteen the second blood moon of an extraordinary series of lunar eclipses dominated the sky we are now in the middle phase of this current tetra or four consecutive blood  according to nasa over the past five thousand years on average there is one total lunar eclipse every one and a half years but current tetra is rare number sixty two in the past two thousand years and there will not be any more in the twenty first century but there is something it work here that makes this group of blood moons very rare jerusalem was returned to israel after the six day war temple mount was seized by israel for the first time in two thousand years just eighteen years earlier there was a biblical tetrode in hundred forty nine thousand nine hundred fifty eight and this occurred during the time that israel was miraculously declared a nation for the first time in two thousand years in addition the dead sea scrolls were also discovered before hundred forty nine we have to go all the way back to fourteen ninety three to fourteen ninety four timeframe to find another biblical tetra during this time columbus was credited with discovering america and  were expelled from sicily during the spanish inquisition many jews and christians believe that the blood moon prophecy is a sign of the end times there are also people who believe that it is nothing more than a unto the end of the world in this verse where jesus says that he is with us until the end of the world something together with my dead body show me a rise rather than this verse talking about bones coming out of the cr i believe that this refers to people awakening and remembering who they are this current biblical tetra in my opinion is part of a global shift in consciousness and will be accompanied by many earth shaking changes we are in the apocalypse which simply means the lived enough to fail december twenty first two thousand and twelve was not a single day as we continue barreling towards september two thousand and fifteen and how that is likely to impact as leading up to september twenty fifth we are in for the ride of a lifetime everyone with all the close schools and man misses the people all over the world have come to accept as the normal level of risk in everyday life was an asteroid big enough to destroy an entire  and comics called it a problem the threat of asteroid impacts on the earth is very real we know that throughout history this has happened the craters we see on the moon are examples of the kind of impact history that the earth is hand but it also happens very rarely so it's a very unusual kind of hazard it's a hazard in which the risk in any one year is very low but it does happen and if it really did come about on our watch it could fragments building blocks of a planet that never quite came together when the so the system was full was often depicted as a busy cosmic junkyard is actually more like a big empty speedway are far apart and moving very fast ranging in size from pebbles to boulders to rocks the size of mount everest occasionally the talk of jupiter's enormous gravity drugs an even small rocks can make a big impression in one thousand to about two thousand square kilometers of siberian forest where instantly flattened as an asteroid exploded near the ton paintings based on eyewitness accounts describe fireball horrendous explosion in the sky didn't actually come crashing down to the ground it exploded maybe five to ten kilometers up in the atmosphere and that made a big blast wave in the atmosphere and that is what did the damage all this was caused by a relatively small asteroid somewhere between fifty and one hundred meters across roughly the same size as an asteroid two thousand and two  commission a comprehensive scientific study of the asteroid and amid threat the expert conclusion was the threat is indeed real the government has set up a tough force to examine the risk of an asteroid hitting there still skeptical politicians might want to get on the bus and take a trip to the natural history museum ask any school child who's been there recently and you'll hear a fascinating and truly scary tale about what happened to the dinosaurs dinosaurs were alive here they were dead when the sediment west positive alvarez to publish a theory that a huge asteroid or comet that hit the earth sixty five million years ago and wiped out the dinosaurs but for this concept to be confirmed the had to be a crater that maybe tons of dinosaur bones in these dry canyons anywhere on earth with a big crater just the kind of mystery a budding young scientist the visible evidence but sixty five million years ago to fight stubborn pain you need a strong pain relief product this was ground zero this object would have fallen through the atmosphere in just a few seconds just going through the sky would have been brighter than  three quarters of the species of large animal behind a swimming pool big enough to swallow an apartment blog you'll find a small research lab where the rocket engine of the future is being built and bench test his rocket engine has been developed for long distance missions to mars or as far away as the icy moons of jupiter but it could also be used to push a dangerous asteroid out of harm's way i am if if this is a a a threat which i saw a very low probability all it takes is one and we are history before we can send a spacecraft chasing after a  to know where to look for it in the american west if you drive across the desert to the white sands missile range in southern new mexico you'll find the most powerful and effective asteroid hunter on a today across the valley floor from the trinity bomb site the u s air force has installed one of the world's most advanced telescopes these may not be the world's biggest telescopes but they clearly are the best when it comes to finding deadly rocks in space given night when we scan the sky with this will find perhaps ten to twelve thousand moving objects in the sky most of those are main belt asteroids and such i don't represent any danger to earth but on the other hand something like half of those will be brand new discoveries and and you do that with a telescope that can track all follow the stars this way you can take time lapse pictures that isolate the blood of a fast moving asteroids against a crystal clear sky less cluttered time lapse sequence of the new discoveries new sightings searching for potentially hazardous asteroids or comets computers make a rough calculation of an asteroids orbit but it's up to brian mazda to estimate the level of risk they may be reporting fifty or sixty thousand dollars of asians from one night and it takes a while to and scientists at nasa as jet propulsion laboratory in pasadena california had to add that to their calculations there's an animation i put together of the asteroid last year which was discovered after it passed by the earth an elite team of it's no longer returning to the same place it started because two thousand and two m n will circle around the sun and come past us again the nasa battle mechanics team will have to adjust the calculation in order to know whether it will ever  danger to earth at some point in the future or here with zoomed in on the earth moon system we're looking down you can see how close it came to the earth it went over the top and how you can actually even see the bend in the trajectory so it's a great example of how close approach to the earth right in fact any planet can be used to or can change significantly change in o to know where an asteroid is likely to be in the future you need a model of the subsystem mechanical models that show the relative motions of the sun and planets have been around since the early eighteenth century the cold already  was create a new digital model one that includes the gravitational attraction of all of us and the sun and all the other forces that can effect where an asteroid might go and it started off at some sixty percent and before long it was ninety percent and this was a year before impacts as the impacts approached we continued to predict not just the impact probability which went very high but where and when the comet fragments would hit the planet and it was a prediction months in advance and as we got closer and closer to the impacts i kept wondering well is are the math is the math right willis actually happened the way it was predicted a giant comet is on and then the impacts occurred we were within minutes of getting the right answer on the time of impact and the location of impact turned out to be just right over the next week twenty more fragments of the comet crashed into jupiter releasing an amount of energy equivalent to about six million megatons in the wake of s o nine a group of concerned scientists gathered in italy for a brainstorming session whose job is it to defend planet earth weapons scientists in the united states and russia had already held a series of meetings and came up with their own ideas about how to deal with the impact threat  reaction the military establishment under star wars had created a whole lot of devices or at least concepts for weapons and space and devices and space and in the early ninety's when the star wars program was looking a little bit iffy i think there was some motivation for them to try to apply their technology to this newly discovered hazard from asteroids and comets the military approach to the problem proved to be controversial the notion of sending nuclear weapons into space and generated an immediate backlash edward teller was proposing that we blow up an asteroid to show that we could protect picked the earth and i thought that was a pretty crazy idea enough an asteroid with a big bomb has a lot of problems associated with it violating treaties taking out a single asteroid making a swarm of smaller asteroids that seem like it was more  interesting bombs was a serious interest in defending the planet for nasa on the other hand nasa obviously is the natural agency to discover the threat and the objects but they say you know planetary defense that's the a military obligation  asteroid nine hundred ninety seven x after eleven seemed to be heading towards the initial sighting by the kid peak observatory in tucson arizona was relayed to the mine a planet center at harvard university in cambridge where a computer made the first rough calculation of the orbit they were pretty sure it would miss the earth on this past but it would be coming round again and it looked like there could be a problem in thirty years there were very rough it was hard to tell where this rock was going so brian marsden posted a bulletin asking us traumas around the world for more observations before the rock that came too faint to see i was saying of a collision was small but it was not entirely out of the question within hours of the website posting reporters discovered accept eleven and doomsday headlines screened around the world up photographs of access eleven taken eight years earlier and as soon as those were placed into the orbit determination process they confirmed the fact that there was no chance that it could hit the earth in thirty public at large was not public and political awareness of the threat had been raised two months after x f eleven new hearings were held in washington and nasa was told to speed up the signs of asteroid detection finally it seems th was a political will to do something congress gave nasa or a ten year deadline to search the skies and get a fix as the universe of data grows and accelerates we need ever smarter story on the largest of the doomsday rocks they called it the space god survey i think the thing that was hardest for me was the realization that people would have to be chosen to survive probably a very very small percentage of human beings would be left on the earth able to survive something of the intensity of the comet that hit and destroyed the dinosaurs so i felt making this movie is not just a mission to tell a good story it's to change minds it's to let people go this is something real to happen to us this movie is a wake up it's not just a hollywood movie it's but instead of using cameras they worked with the late doppler radar take the same technology behind a police radar system jump the power to four hundred thousand does it does three things at once one it works at long way points so you're sensitive to structure a large scales on metal concentration the other is you can take pictures and you can't do this from the ground in any other way you make pictures of objects and  take a sequence of pictures and we go through our computational process to produce the three d models that's the second thing the third thing is that it makes very precise measurements of distance and speed when the thousand  rock held together by weak gravity every time they made the trip to stand for a new right on target and his team were like kids reaching into a box of chocolates they never really knew just what they would find like in the year two thousand the right movie crew developed a dark and mysterious new image asteroid nine hundred fifty d n a a big rock that gave everybody a bit of a shock once we got the radar data we began a normal process of just seeing how far in the future we could predict this thing for the uncertainties in your reply and in this case we could go over eight hundred eighty years into the future and what was startling about that case was coming across the concept here is that asteroid which is about a kilometer across will hit the ocean at seventeen thousand miles per hour and blow a hole in the ocean about one thousand kilometers across and all the way to the bottom and so on this fifty sixty meters up toward canada grand banks it's about forty meters twenty meters here in the coast of south america and about fifteen twenty meters away over to europe these which would run land about four kilometers asteroid four three three zero is thirty three kilometers long and thirteen kilometers wide one of the largest near earth asteroids the pictures was spectacular the data will take years to process proving that they could land on an asteroid was a major achievement but in the end they still don't know much about what's inside how  tough how brutal crumbling you think what would happen if they gave it a good shot of the surface appearance of any dark and mysterious objects can be very trajectory in any significant way plume in one direction and that starts the asteroid moving in the other it's a very gradual process it's not going to happen instantaneously you need to know where this guy is a hundred years or fifty years ahead of time but if you do you've got all the time in the world for a satellite to sit there no human intervention whatsoever and it'll gradually shove the asteroid into a different orbit and it'll the russians have built into testing a giant site that captures a minute pressure of sunlight just a touch the sail to an asteroid and let the wrong hitch a ride to someplace else and nuclear electric plasma engine could push an asteroid out of harm's way the rocket technology of this nasa lab in houston texas could provide the power for a space tugboat a group of astronauts and aerospace engineer is is designing the b six one two mission to prove that asteroid deflection can be done with existing technology these are rockets that have very tiny amounts of a demonstration mission to save the planet we can move the asteroid off me of the earth ten years later so that it misses yours and not just misses randomly but misses very precisely so that we don't simply pass on the problem to our grandchildren two thousand and three the space guard survey had reached the halfway point a little more than half of the kilometer size near earth asteroids and being located and the news was mostly good for the sixty percent that we have already found i can tell you that there is not a single one was a danger for the forty percent that we have not yet found i can tell you nothing one could hit tomorrow now very likely but until we found them in catalog them we won't know but finding the really big asteroids those one kilometer amongst all rocks capable of ending human civilization is only the first part of the challenge there are an estimated fifty thousand smaller asteroids going to think enough to two hundred metre asteroid happens maybe once every ten thousand years but that's like six hundred megatons to eight hundred megatons exploding one but i recall the meaning no one is officially looking for them which of course same thing is saying that chances are enormous that it's a sized object will find us before we even see it coming as happened in in one thousand eight batteries that isn't likely to evolution on earth has proceeded in part because every so often a global catastrophe comes along pushes the reset button and new things happen wiped out the dinosaurs sixty five million years ago and at the time we mammals were just furry little creatures burrowing around in the ground and an asteroid or a comet impact took out our principal competition i guess we are saying implicitly if not explicitly that we want to do away with that natural cycle we've had enough evolution if we like ourselves on the top of the ladder and we can do something with change cosmic evolution from this point forward in terms of life
