cds, despite the delay to morrow to do next. on d, w i she's got, is, is the thought they will gray. it will be with what if an asteroid gets too close to the us. various techniques are being developed to avoid possible disaster even if most asteroids that we know of have been homeless up to now, there have been exceptions. the most dramatic example is benito. what else? the dinosaurs 66000000 years ago.
11:31 am
hello and welcome to tomorrow to day the science program on d. w. now, when it comes to human fossils africa is the chase to look through bone analysis. martin humans have been traced back 300000 years there. but 300000 years as a flash in the pan compared to the many millions of years that dinosaurs from via the 1st ones emerged around 235000000 years ago. also as recently discovered in africa, africa has not traditionally been considered a prime location for dinosaur fossils. but the imperious horace is starting to change that these are bone, fossils from the oldest dinosaur ever found in africa. it lived about 230000000
11:32 am
years ago, making it the same age as the oldest dinosaur remains found elsewhere in the world . joy has to michael xander was part of a team of scientists who discovered the bones in zimbabwe. here we have had you met us of affair, dearest thought f. this ad from this ruth and find if you look at this point, you can tell her that the unmet was quite small. you may assist this one. this is a f capua of the fan that i thought of. ah, he, it comes here from what scientists know so far, it looks something like this. just 60 centimeters tall and one or maximum 2 meters long. it probably walked on its hind legs. never thought of it. fair essaro put them off. dana esl eh, sarah, put them off dana sauce. i have but as long next they have got long teeth
11:33 am
and small head or so we look at the in the of the teeth. yeah. it was a set up at the most where vegetarians saw the tier that designed it 2 feet or 2 cat f as a texas. michael xander was appealing intelligence at the natural history museum of zimbabwe in blue. while was on here, he separates the bones from the rock that's formed around them. over time. the sensational find was discovered near the village of him, berry, hence the name in b resource. on along, we're finding sorratto most in zimbabwe. but we had never found, eh, a sort of a come of that. a size and effect is when you talk of ever listen of dinosaurs,
11:34 am
we can not live out then, dearest us. yes, it is there within that liar. we can safely say it is within the the time frame where the if i nasa originated in bureau where the remains were found is in the far north of a symbol way. the most spectacular find to date, however, was near its southern border on the sentinel ranch. this is where vanessa bristow lived with her family. michael sandow pays regular visits for his research to day. they're driving out together to the place that put this ranch on the map into the site where penny was found. a small shelter now protects the fossil from the weather. it's an exceptionally well preserved muscle pando las likewise a sorrow po to morph. but there will be no further excavation work here for now. this site,
11:35 am
we wic wanting it to maintain and saw that it does intend to push it to doesn't a brick we didn't need to, we put at se if ringing, beg her, all the pieces that men have flipped away. vanessa bristow and her husband often go out looking for fossils which are dotted, all over the farm. penny was discovered in 1993 and we decided to look in an area that we hadn't been to before and found nothing but we knew they were here. and so we mentioned it to his step mother who was visiting the next day and she came up the hill and discovered this. and so they decided to name the fossil after her. this specimen is of especially great interest to scientists because of how well preserved the 4 to 6 meters long fossil is without pause that when it bad it was instantly covered,
11:36 am
though instantly there breathed heavy and did what for, for the last. and did they rock hadn't and because they hadn't eh, erosion did not happen incidentally, that very out. they have committed to protect it. it from of being washed away. michael san dose search for further fossils continues. whenever he find something, he marks the location with a g p. s. device. the land on and around the farm is a real treasure trove. for scientists. i only just beginning to scratch the surface of what's, what's available, and what's to be found. we, we know of at least 15 to 20 sites on the property that yield bones. many of them still encased in rock like this because they keep their findings in this room. like a mini museo,
11:37 am
vanessa bristow hopes they will eventually be enough funding to set up a bigger research facility here. it's now beyond doubt that some bob away has plenty to offer on the dinosaur front. as confirmed by the discovery of imperious sorrows which has not yet been found anywhere else in the world. some 66000000 years ago, an asteroid. more than 10 kilometers in diameter, crushed into the earth. the devastating impact is blame for making dinosaurs extinguish. after a long winter period. the earth continues to be had by asteroids, mostly small ones. but in 19 o 8, there was a giant explosion in the skies over siberia. and in 2015 the people in the russian city of talia bins got a very nasty shock. we wanted to find out whether we should be worried a tree and how tim bag and eastern germany is home to
11:38 am
a high tech telescope. oh he is, his hat shook. this is the centerpiece of the observatory acquisition. come a telescope. he used to detect asteroids that come too close to earth and he did it yet. it's an outcome. it's perfect for the job. yeah. yeah. the new romance, a certain literature, it has a relatively large field of view. that means we can sometimes image several asteroids at once in the area. we're photographic. or you can, you can see a lot of the sky with this telescope. my right. the us has been hit by many asteroids before, which is why early detection is important. the telescope and talton bag is part of a global network of observer trees designed to warn of dangers from space. their results are collected by an international database at the minor planet center. i mean, when it's not clear when you're working at nice and checking the radar as i have
11:39 am
you sometimes been a bit worried about asteroids coming to close to earth. over the years you've been working hathaway eaten yelp and banana addison. and then yan is a guy, right at home is cowboy, who there was once a pretty close shave. wow. what is what's which know why it was identified and then it hurtled past of look on there before, but only at a distance of 36000 kilometers. with reference to 6000. yes, that's how far away the g o. stationary satellites for radio and television transmission are not all, but in the end it patched us. we will get a vague, but the telescopes don't detect every single asteroid case in point in 2013 the child events committee or it came seemingly out of nowhere, observed trees failed to detect it because it came from the direction of the sun. to prevent potential catastrophe the amos to monitor any suspicious celestial phenomena. i love the latina. so what happens on a night shift?
11:40 am
what can i expect? should i have another coffee thinking of in fire as a, as a coffee drinking shorted me coffee is always a good idea to do. that's a good starting from that. and hopefully it'll be clear and cloudless, working for 2 of them. every night the team scans the skies. i'm going to be watching stanislaus melnick off and bring fried stack limit wack during a night shift that going, taking photographs of asteroids just we found a global killer maybe this on this object because it because ah, a bon point like shape this object a built in the base and on the move object should be used to gate
11:41 am
asteroids like those tonners lovers. trucking could end up on a risk list of near earth objects that might one day collide with us. this one, for example, could hurt in 2056. even though the probability is low, it's an object that needs to be tracked. so you can see which way the s read is going on the animation here it is in what direction i have because to the scope, a sort of communion that it can make special drake and when the, the select object cure of the telescope start to follow this has to route using pro promotion, collect from one of the ice and run. we go get the image or the all star saw along need a little quick start. yeah, but if we do so we're all exposure. we can make animation legs and we see motion or foster on the spot and you see which way the estrella is going.
11:42 am
yes, we see the direction at the image is taken might not look too exciting. at 1st glance, i barely noticed the small dots in the upper left area, but that tiny dog is a nearest object, and one day it could strike our planet. right now, scientists are tracking some 29000 known astronomical bodies, called near rough objects. to qualify as in any oh, they need to pass within a 195000000 kilometers of our planet's orbit. that sounds like a long distance, but it's not much by cosmic standards. at that distance, an asteroid is dangerously close to earth. but not all, any of the dangerous of those 29000. only 1300 are on the european space agency
11:43 am
risk list the rest the 2 small or too far away to pose a serious threat if i'm let is read why i don't believe you later. do you have a question about asteroids or about any of his science tells me, let me send it to us as a text video voice message. if we answer on the show, we'll send you a little surprise as a thank you. come on, just does. this week's question comes from ha, ha, mondragon in mexico. what exactly is the dark mission? dart stands for double asteroid redirection chest. it's ultimate aim is to protect our planet from a devastating impact. the tested involved the 1st attempt to change the path of an asteroid by crashing a spacecraft into it. the actual dark orbiter was fitted with just the camera and
11:44 am
a smart navigation system. its destination a binary asteroid system comprising, did a most greek for twin. and it's 160 meter wide move. 10 months after its launch, the orbiter was in place. and on september 11th 2022, it released a tiny satellite called a cube, sat another vital element of the mission. the orbiter then set its site on the asteroid moon, with the navigation system, keeping it on a direct collision course at a speed of 24000 kilometers per hour. telescopes, both in space and back on earth, were tasked with monitoring the cosmic impact. the
11:45 am
data gathered by the james web space telescope and others enabled scientists to work out exactly which materials the small is comprised of. the orbiter recorded a range of images during its approach. relaine them back to earth before impact images that provide a detailed insight into the space rocks texture. the mini satellite also took photos of the impact, as well as of the result in crater despite wing or relatively sketch, 570 kilograms. the orbiter did slightly reduce the orbital speed of its target. earth based telescopes will be able to see how it's trajectory changes over time. the european space agencies, harris spacecraft, is scheduled to conduct a more detailed survey of the aftermath in 2026. it will be joined by 2 cube sat
11:46 am
for determining the size, structure and depth of the crater. the data will show how the moon's physical properties affected the outcome of the collision. there also help to improve simulations of asteroid impacts all in the interest of being prepared for the worst case scenario. many of the world's nations have set up camp and out his face. the tiny face station chung gun continues to expand. europe is sending a probe to the means of jupiter india's planning its mission to venus by 2024. and japan has its side set on mos. but there is one place they all want to go. ah the moon is an average of 385000 kilometers from us. it's surface is covered with tens of thousands of craters. it's only natural satellite has always fascinated us. ah,
11:47 am
are all on july 20th 1969. neil armstrong became the 1st person to walk home the mean 5 further apollo missions followed which gathered important information about its origins. it's hypothesized that an ancient miles like planet called thea collided with the earth and the moon formed from the debris around 4500000000 years ago. before i had fully caught rocks and commits struck its surface, creating its dark lunar plains and craters. then warned, the moon is a piece of earth. it's just as old, but the moon's surface hasn't ever changed. so it's the ideal history book to teach us about the story of earth. because both were formed at the same time. and astronauts on apollo missions collected nearly 400 kilograms of moon rock. please, samples have shown the moon and earth to be more similar than previously thought.
11:48 am
chemically, they're nearly identical. so as the thea hypothesis not quite right after all new samples could give new insights of the morning gibbs off. you know that there are also many resources on the moon. for example, there is water that lies frozen in very deep craters, and this water ice probably still contains organic traces of the comments that hit the moon and the earth all that time ago. and i and that probably helped lightly to flourish on earth, the air, the good. so by going to the moon, we can maybe get a little bit closer to the answer of how life formed on earth can interdiction they are come. in late 2020, the chinese chinese 5 mission collected more lunar rocks for the 1st time in 44 years. they came from the volcanic formation, mom's room car, in the vast luna, mary osi honest parcel r m. a nearly 2000000000 years old. that the youngest samples ever collected they
11:49 am
suggest that the moon has been volcanic li, active for longer than previously believed. but is not clear why the law for abrupt it sign used to think that it was due to high concentration of radioactive heat, generating elements in the lunar mantle. but the latest findings don't back up that theory. they're close at law. the big dream is to fly to the moon and maybe even walk on it just bear lisa is preparing for that right now in collaboration with nasa. it did, we're planning to fly to the moon by the mid 20 twenty's. and by the end of the twenty's, we'll have people on the moon again, mostly mine and just like my colleagues at isa. i also dream of being part of that are not as good. but in the search for answers, they may only come back with more questions. there are still many secrets in the moon's long history yet to be uncovered.
11:50 am
the u. s. space agency assess on returning to the myth. the 1st mission of nasa as awesome as program began late last year with a 3 and a half weeks unmanned space flight 2. it's all based and back. maybe humans will touch down there again in 2025 for the 1st time in decades. ah, thursday, december 7th, 1972, apollo 17 is ready for launch astronauts, ron evans, harrison schmidt and eugene cernan climb into the capsule and prepared to travel to the moon. no one has been there since but the southern germantown of glimmering does offer mankind an opportunity to view the moon up close. a detailed model of the celestial body has been recreated in a scale of one to 1000000 to allow non space travelers to toward the landing sites
11:51 am
of the apollo missions. shortly after 5 30 am local time, the saturn 5 rocket lifted off at florida's kennedy space center. the final mission of the apollo space program and skins or pull up where the hollow project was very expensive. and the american president and senate and nasa and decided to pull the plug in if there was supposed to be an apollo 20. but even before apollo 15, it had left the launch pad in the program was reduced to 18 emissions for. and when apollo 15 combating president nixon decided, so apollo 17 would be the last, of course, it's necessary. smithson, packaging the trip to the moon took nearly 4 days to the applause of mission control and houston. i hear that eugene shannon and tarzan schmidt landed there challenger lunar module in the taurus. literal valley near the sea of serenity. ah, the astronauts then began exhaustive explorations for the ships in one of my apollo
11:52 am
17 marked a new departure, harrison schmid. jack schmidt and a scientist, a geologist was on board and he had a very keen i. he brought magnificent stone samples back to earth, which led to even more new discoveries. my guns, i can't mitigate. gotta nacho wanted to use the final apollo mission to gather as much scientific information as possible. eugene cernan and harrison schmidt were sent on a series of terrestrial training missions, gathering. rock samples is one thing, but doing it in bulky gear makes it even harder and identifying, collecting, and packaging, geologically interesting samples from within a complete space suit is an even greater challenge. oh, my record scientist harrison schmidt made a key contribution to lunar research with his discovery of orange moon soil. oh,
11:53 am
i, if i create the 1st proof of volcanic activity on the moon, like honest the least, one of the goals was to illustrate the moon's geologic evolution to see what happened a long time ago. and what happened recently in the moon's pastures thus had imminent, swiss, etc. and that could have been explored further in subsequent missions, cuz that's the issue with the research. it's incomplete as see here. so mine it wound for ended. we gained a lot of knowledge and set new scientific standards, but there's still a gap in what we know felt miss indic lamasta's up to one but the apollo mission still inspired scientists. the mission brought a total of 382 kilograms of moon rock back to earth. and researchers continue to study at 50 years later, as well as the orange colored material whose discovery caused such a sensation. the others didn't know if log in and you questions arose and they're
11:54 am
still awaiting an answer. that's how science works. and that every question answered raises another 10 i and they will be addressed in the space projects that are now gradually taking shape or based on apollo, 17 and m o r policy. and that will use similar strategies to return to the moon some wants. we're camphyllis, maybe for even longer periods to answer these new questions than fulton 2nd, 7 sick. first steps to return to the moon have been taken. a rocket began a journey to the moon on november 16th, 2022, and left off of us one. nasa wants to build on the successful apollo missions with the new art of his project and his co operating with the european space agency, the isa the successful launch of artemus one, and it's for now unmanned a ryan cru module has once again brought science in close proximity to the moon
11:55 am
where the last visit is from earth prepared their departure. 50 years ago, i said apollo 17 commander eugene cernan. as euston sounded the gopher live dining room. i hear harrison schmidt and eugene cernan let the moon on december 14th 1970 to the moon's last visitors. they were celebrated when they returned to earth. 5 days later, the last time houston enjoyed the successful return of apollo astronauts. it marked the end of the apollo project staying at a point as i believe apollo. 17 was an epic mission that will never lose its place in history. altima artemus will be a different project in his end, if successful, which we all assume it will be. the will earnestly own place on the history of mankind, nym,
11:56 am
moving closer to the precise model of the moon and go meaning and makes it possible to trace the apollo astronauts steps in just a few years. if everything goes as planned, people will be able to take fresh steps on the real thing. that's all for this edition of tomorrow to day. thanks for joining us and see you next time until then stay curious. with ah ah! with
11:57 am
11:58 am
information. this is neither. you news warner w, me for mines targeted killings by combat. drones are being prepared at the u. s. military base in the lunchtime, the problem, the base is on german soil. does german law permit drone attacks? what does the u. s. systematically abuse german law? death by drone, close up in 90 minutes on d. w. o a in. should we oh, do we treat and why hasn't change it?
11:59 am
does this is actually a violation of animal protection. why do we love so as companions? well eating others? yeah, i never thought about how strange it was that i could pet my dog with one hand while i ate a pork chop with the other. what is the alternative and how does it taste? it's like the real thing. yeah. will we all be vegan, and 50 years? i've seen very few strong arguments to keep eating out of a documentary series about the future of food with the great debate this week on t w. ah
12:00 pm
ah ah ah, this is dw news lie from berlin, ukraine's president orders more reinforcement for the defense of bach, moved regional commander his vow to continue their defense of the embattled city. even as russian forces tightened their grip on surrounding areas of so coming up, russia is considering widening a law to make it punishable offense to defame.
