that's it make time for who had enjoyed the difficulty in proving the existence of solar winslow not only in our inability to launch a space mission but also in the fact that the phenomenon was disputed by respected scientists eugene hawkers theory was completely unprecedented and was rejected by many. the referee suggestion i don't alarm her. room board. are going to make such statements. oh. i don't know why i was so dumb part of her some people are just don't see she. knew were a one time change and concepts change there's no change when that there are. change and. they dislike them pass iowa saw. a good rational change is fine.

that over 90 years old mr parker is finally able to reap the benefits of his work in astrophysics 60 years after he discovered solar winds it's now possible to take the 1st measurements and photos of them in the middle of the corona. and the spacecraft has been named the park a solar probe in his own or. the heat of the sun is unfathomable rising to $15000000.00 degrees celsius at its core. the energy is then emitted outward via particles in a process that can take hundreds of thousands of years during this long journey outwood the particles become fatigued diminishing in energy and turning into visible light. scientists have determined that the sun's visible surface still has a. preacher of 6000 degrees however oh oh ellen.

the space probe is prevented from melting mainly through its he chilled composed of carbon compounds a mere 11 centimeters thick. but the question remains as to whether this will suffice to protect the measuring instruments. while the side of the heat shield facing the sun is meant to withstand up to $1400.00 degrees the dark side will be almost room temperature in addition a water circuit cools the solar cells in order to prevent them from overheating. and after all temperature is not the same as heat temperature is only a means of measurement while heat itself is discharged energy. in gaseous heat the energy particles are spread out so thin that the probe would hardly come into contact with them meaning despite temperatures in the corona of 2

to 3000000 degrees the heat doesn't pose a risk to the spacecraft. home at nasa the parkers solar probe was almost finished and only a few tests remained on this mission success would depend heavily on whether the camera mr howard and mr boatman had developed was stable enough even for a space flight or their design is very sturdy weighing in at 10 kilograms but a rocket launch is so powerful that it's necessary to conduct a special vibration test. this is a critical point for all space missions which is why there's a dedicated laboratory where the vibrations can be simulated. part of constructing a space experiment is proving that it's going to work in space that it's going to

survive this very violent launch i mean i i can't imagine being an astronaut sitting on top of a rocket. during during the launch it's just. that they're just boggles my mind that somebody would do that knisley. it's a very tough ride and but that so that the vibration is is part of the launch the launch sequence. the camera cover could also present a problem because if it were to fail to open the lenses would be blinded. the parkas solar probe thus underwent test after test. 3 months before the law. which covered that we have a problem with a set of heat sensors on the spacecraft. we had 87 of them. on

the spacecraft and just a few of them and when i say phew i think it's 3 or 4 feet. i remember that they vividly it was it was absolutely like the guy. and the team was so nervous i mean we are seeing the finish line. but we may not cross and that was that was not a good feeling to have but the team is so great so. in a month and a half. they came up with a solution. we installed the new system of its sense of spacecraft. but on top of that figured out what what was the root cause of the failures of the other door system and now when the spacecraft we have to system of it's sensors and they are working both live together and beautifully without problems. only the largest available rocket the delta 4 heavy could provide enough lift to launch the probe

from cape canaveral air force station in florida. 65 k. e 3210 such as the mighty delta for having a rocket with masses of parker so a cold. on her back and that day in 2018 a lifelong dream of eugene parker's came true. the

further away the probe is from earth the more difficult it becomes to communicate with it and directly at the sun there is radio silence. operating like a sort of probe is one of the most challenging arm aspects of the mission. when we get into the encounter more when the spacecraft is very close of song it has to be 100 percent of one of us and by that i mean if there is something that happens of spacecraft it has will repeat such we cannot intervene we cannot do anything for . a worldwide network of van tenors and mabel's data to be exchanged and yet contact between earth and the probe is only possible when the 2 are in a particular configuration with each other.

so basically when we get in the. encounter mode the only way to communicate with spacecraft is what we call a beacon problems and because those are fairly limited bits of deliberately that tells us the overall state of the operation level of the spacecraft and they are emitted but we called the fund beams and this fund beams that emit basically 180 degrees wide. beam of radio and the earth has to be very. well usually in order to detect it for good and hopefully today we get to problems so the turners tucked behind the. yes it would not see the direct sunlight sunlight load it all has to operate in group temperature. so let's look young. now all the scientists could do was wait and see

until the parkas solar probe could transmit its 1st data a journey that would take $88.00 days and nights $88.00 days that would pass according to the rhythm of the sun as they have passed for millions of years. solar time is the time shown by a sundial the engineer carlo helen developed sundials himself and he and his daughter a well acquainted with the rhythm the sun sets out for us and how the day is divided into hours and minutes. and the sun dials produced here you can see that our official summer and winter times rarely coincide with true solar time yet solar time is crucial for our bodies . is on the k.t. amongst all the sun rises in the morning and when it reaches its zenith this is

referred to as solar noon the real midday zones and it's defined as 12 o'clock solar tartuffe and this noon divides the day into 2 halves of exactly the same length and our circadian rhythm is based on solar time and centered around 12 o'clock noon or simply that. our bodily functions depend on this solar time and sun dials show us which phase of the day we're in. the sonic youth. as the sun rises our blood pressure and body temperature rise and we wake up and then when the amount of blue light he creases again isn't evil and our bodies release melatonin and we lie down against his sleep and the next morning it all starts back over again thanks to the sun. the sun's power and radiance are immense and there's no doubt that we live in its

atmosphere as scientists say making it all the more urgent for us to explore the sun's mysteries using all the means at our disposal. if it is only we will observe the sun with telescopes we will also measure the breath of a sample in the solar wind as it passes by the satellite and if we can really make that connection with data from the parkers sonar probe we will really be able to reconstruct a chain of cause and effect and manage to better understand our place in the solar system as a 1st in. the nasa mission is going according to plan so far with the parkers solar probe sending its signals to worth on time there's a feeling of suspense in the control room whenever a new dater is expected because the special camera developed by mr boatman and mr howard is already providing sensational pictures after the 1st phase of the mission

it became clear to the scientists that the image we had had of the sun so far was far too simplistic before the launch we had a workshop to. basically to make predictions of what corporate backers sort of probes going to see in space all the predictions are completely wrong. what we are seeing in the data isn't youth new phenomenon that if you nominate but we never seen him for so long before. it's now clear that the magnetic field lines of the sun do not spread out evenly but instead they call spontaneously zigzags within seconds and this may be a key element in understanding solar storms. the 2 probes will continue sending data earth for several years and each revolution around the sun will reveal new findings.

science will try to provide us with the answers to pressing questions in order to protect us from the dangers posed by the sun. this is. actually he has been dead for 22 years. is a cloud. from frozen genetically. and providing hope for endangered species. concerns biodiversity fighting species from beyond the

may well become the country's next leader. i'm michael fellas welcome to the show. it's a milestone nobody wanted to reach 2000000 people have died from covert 19 in the year since the outbreak began despite governments around the world racing to vaccinate their populations most of them have so far failed to stem the relentless rise and deaths and infections brazil has the world's 2nd highest death toll with more than 200000 covert fatalities lockdowns haven't been able to turn the tide and authorities and one city in central brazil are now admitting that its health care system has collapsed. the ambulances keep on coming

they bring a relentless stream of coronavirus patients to the hospitals in the brazilian city of manaos. manaos is the capital of amazonas a state hit particularly hard by the pandemic overburdened hospitals are now running out of their most vital supply oxygen this growing shortage is costing lives. never more yours my grandmother died today because of lack of oxygen there were 21 patients in the intensive care unit and my grandmother who is 84 years old didn't survive she needed 15 leaders of oxygen and didn't get it. the. protesters are blocking roads and picketing hospitals they're angry at the government and demand answers. over to the i've been here since 9 am and seen just how desperate people are i don't even know how to explain what's happening in our country and in our state it's unacceptable for there to be

a lack of oxygen. and there is absolutely no explanation for this. because so the government has responded by flying in additional supplies to the embattled state. the shortage has given rise to a new type of crime police footage shows oxygen cylinders that had been illegally withheld to drive up the price. amazonas has been here before last year's dramatic images of mass graves carved into the rain forest shocked the world. brazil's health minister blames local authorities for the crisis. but my nose did not have an effective action plan for early treatment with clinical diagnosis basic care and that has greatly impacted on the severity of the virus

also the specialist care hospital infrastructure in manaos is quite small in percentage terms are you. going to buy a more modern. wall but as the ambulances keep coming in a country 2nd only to the us in corona virus deaths there is plenty of blame to go around. us vaccine manufacturer of fives or has told the european commission it will not be able to fulfill all of its promise deliveries in the coming weeks that's because of building work intended to boost production at its plant and belgium where the e.u. member states dependent on the pfizer vaccine for their immunization programs it's a major setback in europe's battle against the pandemic. pfizer's plan where it's from here that every country in the world except the us will be supplied with its vaccine it's a complicated manufacturing process doses have to be kept at ultra low temperatures

and the united some of the deliveries could not be to lead a complete surprise to the e.u. . these are all of course a question that pfizer company has to answer i think it is very important that immediately we make clear that there is a guarantee of. that have to be delivered in the 1st quarter just a week ago the european commission was in talks with pfizer about delivery arrangements there was no mention of. the company wants to carry out works its plan to adopt the manufacturing process and that it says would significantly boost production in the coming months several e.u. countries have urged the commission to peer pressure on pfizer they've described the delay as unacceptable and see it will have a profound impact on the credibility of the whole vaccination campaign. so take a look at some other stories making news around the world opposition leader bobby

supposed to be there at all you know it's a very very good marker. we called the. south right up there's a creek they've that they've done since wednesday is definitely needed and i do feel better about it but i think that the brightest still there at the current is shaky i just want to make sure that this time that they're actually doing their job to protect the city as opposed to you know they are prepared like leicester. and the fans it's all hands on deck. with soldiers from 11 states have arrived in washington d.c. they are organizing their equipment checking their weapons and getting ready in case violence returns to the city. they still don't know for how long they will stay deployed here. but the ones who spoke to us say they are proud to be here and to defend their democracy. but it's also

a logistical challenge. for now they're waiting this might look like a military base but we're actually in the heart of the capitol building the soldiers are resting here they're having lunch and they're getting prepared for generally trying to inauguration day. nobody knows what awaits them. the folds still bears signs of last week's riots. or. progress through. her. and now they are here to fix. here in germany chancery mackesy vu party is about to elect a new leader it's a key vote that will shape the party's future direction and could potentially represent a 1st step towards determining the next chancellor after more than 15 years in the

top job chancellor merkel is not seeking another term and 2018 she was replaced a c.p.u. leader by on the good come cousin fail to stand for authority on the party and announced last year that she would step aside the race for the leadership appears to be wide open with 3 very different candidates on the all male ballot ahead of saturday's vote we want to know about this she have a preference. yes i'm going to machall does have a favorite to succeed want to try not to show it when asked months ago whether the man next to her has what it takes to become tongue. hoping that the middle of always said that i won't interfere in the succession of the position i have or had and you see do you party leader will be elected in life said is a candidate and a state premier of north rhine-westphalia he brings many qualifications to the

table. by medical standards that's strong praise i'm unless it stands for post medical continuity something he demonstrated in the candidate debates he's playing in it i bring to the table experience in government as leader of a large state balancing our interests and it might come in handy that i've actually already won an election as these next elections are just sizes. people mattes once to turn the c.d.u. back to its conservative roots he once left politics after losing a vote to anger machall a man keen to see the end of machall style centrist politics. we need is competition for the best ideas to define the political center to put it more bluntly i believe that in politics nothing and nobody is irreplaceable know about what ministerial career was also once dented by magical political dominance still

the underdog he has carved out a chance at the leadership by pushing his vision of a germany asked her to tick global player. strength is the answer and strength only comes through unity so we need a european china strategy and that also means that germany has to stop simply seeing china as just one of its most important markets also market spots. the next party leader will also be in pole position to run as chancellor the latest poll suggests it will be a close call when the 1001 party delegates vote on saturday with mats slightly in the lead but when see do you supporters were asked who would be most able to win the federal elections in september and become next chancellor a stunning 80 percent named someone not even on the list marco sudha he leads the c.d.u. sister party and bavaria. and there is another dark horse with

potential germany's health minister yet spawn is leaving his options open to. so the on so who will succeed. may still be months away yet so today's vote for a new party leader will decide how her c.d.u. defines conservative politics in the future. a court in munich has sentenced a doctor to 4 years and 10 months in prison for his role in years of illegal doping in sport the landmark verdict includes the 1st major prosecution under german anti-doping legislation introduced in 2015 the accused has admitted to giving illegal blood doping treatment to numerous athletes primarily in cycling and winter sports he's also been handed a fine of 150000 euros and banned from practicing medicine for 3 years. as the trial drew to a close mark suppose the judge for his doping practices blood manipulation was his

modus operandi he and his accomplices would take samples from athletes enrich them with red blood cells and reintroduce them via transfusion the guilty verdict has been hailed a milestone in germany's top income pain. it's finally a clear and significant punishment has been handed. one of a severity and a clarity that sends a valuable signal also in regards to the upload cation of the un to. doping does it says. in the case of austrian mountain biker christina. the doctor experimented with hemoglobin poser meaning he was also found guilty of grievous bodily harm. has been in custody since february 21000 raids on the doctor's house in germany led to his arrest at his practice. painters believe the judgement will act as a deterrent but others are not so sure. just.

germany has been around since 2015 and this is the 1st and so far only case of doping in elite sport brought against the personal doctor in that sense the investigative quarter is in my opinion small and many will know that this is more or less an isolated case. both parties have a week to appeal the verdict. special is up next thanks for that. thanks for joining. the fight against the corona virus endemic. as the rate of infection in developing . the latest research. information and context around a virus update. on.
