the human cost is still being counted. the number of people under the rubble is still unknown as we've heard from the families and the neighbors it's a large number i was still working here. israel says it's overnight strikes were targeting a senior hamas political leader and taking up tunnels and rocket launch sites the response from hamas came quickly israel says about half of the militants rockets have fallen short or been intercepted by the aerial defense system. but others have hit their targets residential areas such as here in tel aviv one man died when a hamas rocket struck his house others narrowly escaped death. 2 more meters and it would have been my house. coming out of. israel's

destruction of this gaza building hosting several media outlets has raised international concern israel says it was also used by a hamas intelligence operation associated press has demanded evidence and says the world will now know less about what is happening in gaza on saturday funerals were held for 10 family members killed in an earlier israeli airstrike only a baby survived desperate diplomatic efforts are underway to broker a cease fire and avoid more such tragedies. we now have. in washington. is standing by tanya 1st to you what's the situation on the ground any more violence today. well we seen an earlier just an hour before this broadcast and marry a massive rocket barrage into the south of israel coming out from gaza and

targeting you know. cities like a school and a start but also their ships there are also more airstrikes on gaza on different places stair. we also know that the rescue efforts continue after this strike in the early morning on the presidential building deborah people were still trapped under the rubble and we're also hearing from the hospitals not in gaza that they're really strange and possibly overwhelmed with a constant intake of injured people now egypt has said they're opening also they have opened at the border crossing to take in some of the injured people we also have tensions here in jerusalem we are hearing here in the past half an hour or so a lot of sirens and police here in the neighborhood that something happened we will update you on that obviously still a very dynamic situation in this poll in washington the u.n.

security council meets soon in new york what can we expect there. well the question will be how strongly biden the u.s. president will really condemn the latest action also because the democrats within his own party are really getting louder now and wanting the president to be more forceful but you know there is no dollar whatsoever that the. united states would bedo any military action against israel and we have to keep in mind that in recent years all the u.n. security council resolutions have not really being implemented specially when it comes to the right for palestinians to build their own state perhaps a foregone conclusion there we will see tanya e.g. there any chance of a cease fire any time soon. well i think there's a sense that there's room. for maneuvering after both sides become

a bit tighter. you know also the pressure by the international community might be it might grow as well as humanitarian situation in gaza which has already been very difficult here eating up by the hour however the situation regarding its sistar remains unclear security company by the israeli government has now ended their reports before that they might discuss a possible cease fire look at proposal it's now we're not so sure about this different reports of one saying also that it might or might opt to continue. operations now we know that egypt is trying to mediate act together with other countries also the u.s. envoy is here. in israel he also spoke to the palestinian president mahmoud abbas but at the moment you know nothing really tangible to see if anything is

imminent or will happen here with regards to cease fire. you know so i'll give you the last word here the u.s. is trying to make that cease fire happen is to bite in administration regarded as an honest broker in the conflict. that's a good question i mean as we know that president biden called talked into a separate phone calls with netanyahu and abbas yesterday trying to really kind of broke a cease fire and we also know where this and netanyahu just posted a couple of hours later on facebook that he's not willing to do so so that is not a good sign for the biden administration in the regard that they really have something to say in this conflict at the very moment so that indicates more or less that the possibility is off diplomacy are very limited at this point for the united states you know poll in washington in tanya kramer in jerusalem i thank you both

turning off some of. that great no i'm sorry to disappoint you that it was me not the president today obviously would have probably made that stunt a little bit more interesting was 7 the stunt though voiced the same disapproval that japanese themselves are voicing in small protest groups and in big polling data that shows 59 to 65 percent favor canceling the games in light of the pandemic . i was surprised that the number of people who are against the olympics have increased this much but i guess that reflects how bad the situation of the coronavirus lives. but olympics organizers are moving forward and one thing that did go according to plan for them are dress rehearsal of what the track and field competition could look like. a mostly empty stadium say for

athletes and officials who've been placed into a virtual bubble. 4 time olympic medalist justin gatlin won the test 100 meters and was a few sivan his praise despite living in a locked down room to sleep to watch netflix to dine and then he was let out to train and compete. this competition here was a precursor to see exactly how you know the olympics can go off. maintaining a bubble for the athletes to be able to stay healthy and also the citizens of japan to be able to stay healthy with foreign athletes for an athlete coming into the country i think it was a success. definitely different it's going to be hard to adapt but the caution is definitely needed. should the games go off as imagined or imagined this could well be the look world class competitors inside the venues and the athletes olympic village. protests on the outside.

you're watching news coming up after the break a documentary looking at solar storms we will have more news in headlines for you at the top of the hour and don't forget you can stay up to date with the latest on our web site d w dot com i'm michael okun in berlin thanks for watching. more . species. expect. to see the secret language of oil. company a research team to the pacific to. rejoin whales starstruck. for

untold thousands of years we have relied on the sun's light and warmth its powerful rays making life and growth in our world possible police we worship and adore it. however the sun also expels tremendous plasma storms and these eruptions of energy charged winds up potentially capable of disrupting our power supply resulting in a global blackout. in far. to look even the infrastructures and technologies we use are vulnerable to space weather if it. doesn't help us because they are grateful for the sun but it also presents a major answered for us particularly when there is solar storms does. these storms occur time and again at irregular intervals of up to several years and the last one

in 2017 fortunately missed planet earth. in order to solve the enigma of solar storms nasa scientists have now developed the 1st probe that can fly into the sun and approach it more closely than ever before. will this enable scientists to investigate the risks posed by the storms or are we at their mercy. in. the astrophysicist folco boat researches the sun and is in charge of the german team working on building this new probe all its sides have to be equipped with sensitive instruments capable of withstanding the extreme forces and temperatures.

the most crucial component is a camera capable of observing the solar storms and foca boatman is responsible for it the curtain falls on sure we can give an early warning about solar storms by making the appropriate base observations and there are some observations that can really only be conducted from space you need satellite technology and cameras on board which provide you with lead times and any precautionary measures taken depend on these lead times. the mission is meant to help provide advance warning and neighboring us to better prepare for the storms. but for this purpose research must be conducted on the origins of solar storms and the question as to why they pick up speed so rapidly in fact they reach such high speeds that it takes them just one to 2 days to reach earth where they he says at 7000000 kilometers an hour

. a comparison of full blown tornado rages at a speed of 500 kilometers an hour. and never before has there been a mission that has flown so close to the sun. such an approach is risky and so the probe must also set completely new standards nasa scientists call it the parkers solar probe. will be flying about 6000000 kilometers from the source or for us if this is the sun earth distance back a sort of appropriate beef like this close to the sun. the parkas solar probe will come 96 percent closer to the sun than earth and the outcome of the sam bishes mission remains uncertain but this is the only way to explore how and when solar storms occur this is where there is no question that

a strong solar storm will happen in the near future it's just a question of time and we want to be as well protected as possible before. because if a solar storm catches us off guard he causes incredibly high temperatures capable of melting even the biggest transformers in substations as occurred in october 2003 in south africa a widespread abrupt power outage would put water works in their pumps out of service. at the same time pipelines would stop conveying oil because they too run on electricity extended power failures caused by transformer damage would bring nearly everything to a standstill since even emergency power generators can only keep operating for so long scientists warn that everything would come to a stop and food shortages would occur. earth normally boasts

a magnetic field that protects us from solar particles however when solar winds turn into a storm this protection is no longer sufficient. the mass of plasma then presses against the magnetic field compressing it. roman laon heart of the conrad observatory i'm in austria has been recording changes in earth's magnetic field for years and such geomagnetic measurements can then be used to detect solar storms. protected from external influences he has ensured. and conditions for he's measuring instruments here 50 kilometers southwest of vienna in a geophysical research facility on travel bad mountain. normally this magnetic field is rather quiet with hardly any movement but when

a solar storm hits we see a significant jump in activity. these measurements of earth's magnetic field are important in assessing the solar storm data recorded by satellites. the more data available to us about a solar storm the better we can predict where and with how much force it will reach earth and how much a dangerous energy it will unleash the key question is when a solar storm will overload the power grid. professor renna has developed a system enabling him to determine how the extraordinarily high currents will impact the power grid based on geomagnetic measurements taken here in this observatory. solar winds hitting earth are also visible in other ways the magnetic field lines on the side facing the sun connect together and enable electrically charged particles to flow into earth's atmosphere there they stimulate atoms making

them glow. so it's actually the effects of solar storms that cause the northern lights of the poles sometimes in red and sometimes in green. in the event of strong solar storms the lights are visible farther away from the polls as well continuing farther and farther toward the equator. it's as rare to see this phenomenon as a total solar eclipse. when the moon passes in front of this. sun we see a bright halo of light around it known as the corona and that's where the parker solar probe is flying because it's where solar winds are created and precisely where something unusual happens if you have a comfort the further away you move from it the cooler it gets but does not work

for the sort of core when you look at the surface of the sun the temperature is about 6000 degrees move up about 23000 kilometers and the temperature of the plasma would jump to more than a 1000000 degree that is completely counter-intuitive it would not it would not be that way but sun magically dust things that are out of the ordinary and one of them is what we call the corner hitting the corner is more than $300.00 times hotter than the sort of surface. understanding coronal heating is crucial for the scientists and it's why folk of bode miller was determined to take pictures there and to quit the probe with a special camera in collaboration with his nasa colleague russell howard in washington d.c. . the nasa scientists in washington had not yet decided whether the probe would have

a camera on board as its load capacity was limited. folco boatman not only had good arguments on hand but also had long been friends with his american colleague russell howard they both shared an affinity for the sun. i walk or you good to see you thing from your bed oh it was a good perfectly good. in the end to russell how would too decided to install a camera on board the parkas solar probe and began making 1st drafts of his space camera an instrument he would like to take special pictures with i actually love to talk i've always loved harvey so this is this is amazing. my personal goal was to really to have an instrument that i could see see the sun see the corona not the sun but the courts or corona. the

camera needed to have a view angle that would capture the corona around the sun and for this purpose it had to be placed at a certain position on the probe. here we have a model of the of the whisper instrument and what we do i think to be in this position. of them. on the spacecraft. and just just about so. the camera would be very sensitive to light meaning that boat and howard would have to prevent sunlight from being able to shine on to the camera's lens while it took photos of the corona. i think were said could you switch off the light walker yes and walk toward us. to do is that it's important for the sunlight to be shielded off because the camera is meant to observe structures in the solar wind and the corona that are millions of times less bright. the heat of the sunlight is also so dangerous that the camera

must always be protected by shade. after long consideration an agreement was reached on the concept and construction of the camera could begin. it owes its unusual shank to the too wide angle lenses while the camera cover which protects the lens is installed beneath can be opened on the side. but when taking pictures the exposed lens is appointed in the direction of flight and dust particles from space are expected to hit the front lenses at high speed meaning damage is inevitable. it was hard to predict how hard the lenses would be impacted as boatman and how wood would breaking new ground. but they couldn't risk the camera being blinded so they needed a glass with

a special extra top surface and tried out different variety something you see at me with the naked eye yet i can see some spots a lot i want. oh that's interesting and i can compare it with everything with the other 2 types. so much to both small cults it looks like. what'll happen is when one of the best is coming out we're going to see it and then the spacecraft will run into though that. we're going to be flying through that sort of harsh particle environment i mean that's a risk. it's sort of like dust on your car window that you get these impacts and when if you have a very old car you have a lot of dust impact and when you're driving into the bright sun it's really difficult to see. so. it's the same problem that we have.

folco boatman and russell howard already have valuable experience building space cameras together on a previous projects they photographed solar wind in 3 d. . what kind of cameras to buttress to have on board that's never been done before. we don't have such cameras that's correct. in 2006 the missions sent off to satellites at once called stereo a and stereo be enabling the solar wind to be photographed from 2 sides at once but only from a very long distance. the grigor solar telescope stands at an altitude of 2400 meters at the foot of pico dealt a day on the island of 10 a refit where almost ideal conditions prevail for observing the sky.

as the largest telescope in europe this telescope helps compliment observations by the park a solar probe from earth. usually air turbulence in the atmosphere poses an obstacle to observing the sun from earth but luzzi a client has a special mirror in her telescope that can compensate for such distortions. what's more the swiss scientists can observe the sun around the clock from here. parkas all approach the pakistani probe can take measurements they're not using certain periods when it's close to the sun while we can take solar measurements every day. the telescope strong point however is it's particularly high resolution unable in the astrophysicist to study the sun spots with precision.

is on the head and his son has an 11 year cycle meaning that every 11 years it exhibits a particularly large number of carnal mass ejections and sunspots and we've been aware of this cycle for centuries in the past sunspots were seen as somehow evil because every time their current they lead to disturbances and so less storms but we now know that sunspots are actually just cool areas on the sunset. around the stance the sun's surface resembles a pot of boiling water with hot plasma rising from the depths cooling down and sinking back down again this results in a vibrant pattern of bright bubbles with dark ages. and investigating them took fine tuning and cooperation. in solar physics we always try to aggregate the data from all telescopes and space probes because only by combining

them can we really find out about the sun. if such extensive observations had been being carried out back in 1909 canada might not have experienced the devastating power outage that affected 6000000 people. in the winter weather of quebec at minus 7 degrees not only did the district heating fail but the children's hospitals power suddenly went out in the middle of several surgical operations. the transformers couldn't handle the enormous power surges. in austria the electricity grid provider a.p.g. therefore operate special transformers designed to compensate for the hazardous d.c. currents caused by solar wind however it will take decades for these kinds of transformers to become commonplace because due to their prohibitive costs electricity grid

operators can only install such transformers here in there a solution must be found and fallen. when our solar wind head south it so facts are not limited to a small space but they actually impact a very large area meaning multiple transformers will undoubtedly be hit by numerous elements by all at once however this naturally results in power outages and in the worst case even a blackout because. bowker both know wants to make sure that solar storms do not become nasty surprises which is why scientists shouldn't be the only ones privy to the solar data recorded. instead there should be an easily accessible option for anyone to quickly get an idea of the sun's conditions and folk a boat has developed an app that directly displays nasa's observations of the sun.

well good government since the topic is becoming increasingly important to us and society i wanted to develop a space weather app enabling you to have easy access to information about the sun's activity at any time along with what consequences that might have in the coming days. reading tea leaves to forecast solar storms is no alternative to scientists working with validated data to make their predictions even if they are tested to their limits. of this on this is on is so complex that you can simulate it as a whole you can imagine it's magnetic field like a rubber band running from the north to the south pole since you will still have that the sun rotates fast it is quite evident at the poles meaning this rubber band gets twisted up which is precisely what leads to say list storms.

the magnetic field lines bind tons of plasma to them however if they become so in tangled that they burst open they hurtle this plasma out into the void of space. as it's still relatively young clay whether solaced on scandal or predicted at all because if there are storms a totally chaotic will never be able to predict them several days in advance. solar storms not only here planet earth but also the spherical zones around us which are home to orbiting g.p.s. satellites among other things and these form the basis for around navigation systems. this case there is the g.p.s.

is disturbed by solar storms this also has your determined position you'll certainly know you're in europe or america but anyway know if the runway is ahead of you or to use only the navy. imprecise navigation is a nightmare for pilots and aviation safety with accurate signals absolutely mandatory in order for nothing to go wrong. this problem can pose life threatening risks for example when japan temporarily lost control of 2 g.p.s. satellites in 2003. g.p.s. signals move through the i own a sphere that surrounds earth like a shell so if it's deformed by a solar storm this distorts such signals. let's during the last strong solar storm a few years ago about 60 aircraft were not allowed to take off and a flight radar. failed in scandinavia who called dos it's got. some american

airlines are already taking space weather into account and the international civil aviation organization recently established a working group to determine when aircraft must remain on the ground. we need hard space weather data for forecasting and we need appropriate standards enabling information to be passed on worldwide as to what effects can be expected under what space weather conditions and what actions must be taken but that is still in the process of being developed for the coming years. and nature has its own struggle with space weather with some birds and insects for example the monarch butterfly relying on their own navigation system based on earth's magnetic field. this normally enables them to reliably find their way to their winter home however if earth's magnetic field is disturbed by a solar storm the sensitive insects get lost.

in autumn when the sun is no higher than 52 degrees in the sky it gives the starting signal for millions of monarch butterflies to begin their 3000 kilometer journey from the higher latitudes of north america down to mexico. every year they land at exactly the same place again within an area of just 20 heck tears for 5 months they take in the sun along the pine trees before starting their return trip. but they lacked the strength to persevere for the long trip and will never reach their distant home in north america. the parkas solar probe also requires a lot of energy for its long flight 1st it must fly to faraway jupiter to pick up extra momentum and be flung by its gravitational pull before venturing onward to

the sun. but the concept has been the subject of spirited debate among researches because the side trip to jupiter would require the probe to be equipped with its own nuclear power plant entailing an enormous investment even for nasa guys i wonder if we think yeah that's progress i think we have to discuss it because most of your focus boatman discussed the flight route with the nasa team once again and the costs were too high so when you trajectory had to be found russell howard and folk aboard considered one path might work as an alternative to the jupiter route we're going to change the trajectory of our satellite by hitting venus and then. go directly to the sun and i could see the ok so here i am sitting on my rocket i have to get the speed right true.

in the end the nasa scientists agreed that the probe should start off toward venus where it will be slowed down by passing by before continuing onward to the sun. these also significantly increases the available measuring times because the parker solar probe will not go around the sun just twice but $24.00 times. the european space agency e.s.a. is also working on solving the mystery surrounding solar storms and have also been developing their own probe for over 12 years called the solar orbiter. that's. a special thing about a solar orbiter is it trajectory which will take us out of the plane of the sound system all our observations so far from the perspective of. and because all the planets revolve strictly within the plane of the solar system like on

a record player it would take a lot of effort to escape this ecliptic and we feel what we are missing is data from the solar pole about the only way to see the poles is to fly out of their clip take and observe the poles from above. danielle miller coordinates the various solar orbiter teams and one of their biggest challenges is to ensure that the 1000000000 euro object can withstand the heat in france for example various materials have been tested for years to do just that. new sums i.v. i develop a process we have managed to develop special materials and methods for these instruments enabling them not to melt. really metal you off of so that the instruments can continue taking measurements and achieve the expected result nearly as are documented on. 10 different measuring instruments have been developed for the sole orbiter one is able to detect the x.

rays from the sun with this instrument physicist luzzi a client utilizes an optical grid that the x. rays pass through. an important stepping stone in the study of solar storms. in safe and visible light you can only see the effects of soda eruptions that's true x. rays you can investigate their courses in our instruments we have 2 metal grades and on them you can see a pattern caused by the x. rays on the pattern is highly accurate and varies depending on where the soldier eruption occurred on the sun thus allowing us to determine exactly where the particles came from that fund. this special ability to locate the eruptions is unique to the e.s.a. solo orbiter probe nasa is park a solar probe can't do that so both probes will complement each other. assembly had to be 1st with just

a year before launch the probe and all its details had to be finalized. meanwhile the start up procedures were being tested in the control center over several months. ago. you know only 2020 the probe was finally ready for launch. in the year on the army would be a good memory and we are going to be off. the solar orbit so we'll spend 7 years collecting data from the sun employing its 10 different on board measuring systems all from different european countries. personally the sonar orbiter has meant a lot to me because it has shown that you can build a very complex things together with

a lot of other people all incorporating their different areas of expertise i've seen over the past 12 years how many people have invested many years of their lives giving it their all to make this as good as possible. in bed. as to getting solar storms has been a long held dream for many nasa scientists too as early as 958 when nasa was founded there were those who wanted to conduct a mission to the sun at the time assistant professor eugene parker had only just proposed the theory that there might be solar winds for his bold thesis to be verified they would have to we're going to use a mission to the sun we knew that the space age was coming and that we would soon test directly whether there was a solar well. i'm going to search for a matter of a few years or china. doesn't make time for who had it on the difficult same praising the existence of solar wind slay 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. there are various things just and i go on a lot of her. career bob some 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 see things. in a new way one time changes and concepts change there's no change when that there are. changes in. their dislike of them pass i always thought of. a good rationale change is fun.

and 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 parkers solar probe in his honor. 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 outward the particles become fatigued diminishing in energy and turning into visible light. scientists have determined that the sun's visible surface still has a temperature of 6000 degrees however. lowen.

the space probe is prevented from melting mainly through its heat shield composed of carbon compounds a mere 11 centimeters think. 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. at nasa the parkers solar probe was almost finished and only a few tests remained 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 is just that that 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 if it's 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 gave italy it was it was absolutely like to go. 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 are stored the new system of its sense of spacecraft. but on top of that figured out what followed what was the root cause of the failures of the other the or system and now in the spacecraft we have to system of it sensors and they are working both the 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 am free to walk 0 such as the idea delta for having brought you with masses parker sort of go. 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 purpose or approach is one of the most challenging aspects of the mission . when we get into the encounter more when this base craft is very close of song it has to be 100 percent autonomy us and by that i mean if there is something that happens with spacecraft it has to solve repayed stuff we cannot intervene we cannot do anything for. a world wide network event 10 is unable dated 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 trolls and because those are fairly limited bits of deliberately that tells us the overall state of the operations level of the spacecraft and they are emitted but we caught the fun beams and this fun beams that emit basically a $180.00 degrees wide. beam of view and the earth has to be very light and there's this 1000000000 years and in order to detect it for good and hopefully to there we've got to be controls so the antenna is tucked behind the. yes it would not see the. sun silo that all has to operating room 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 . it's only get amongst all the sun rises in the morning and when it reaches its zenith this is referred to as solar noon the real midday zone site and it's defined as 12 o'clock solar

tartuffe and this noon divides the day into 2 halves of exactly the same length on our circadian rhythm is based on solar time and centered around 12 o'clock noon and were sent to me yet. our bodily functions depend on the 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 is evil and our bodies release melatonin most and we lie down again to 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 is 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 what we will observe the sun with telescopes but 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 i stated. 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 parker prepackage sort of probes going to see in space. all the predictions are. what we are seeing in the data isn't youth new phenomenon that if you know me not that we never seemed to saw it 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 so 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. when you combine the 2 way that makes eco friendly transportation and oberlin start up that recycles batteries from electric cars what you get are emissions free cargo bikes for women who live in the countryside. immobility for zimbabwe because africa. 13 d.w.
