: ipse you feel the connection with space. >> woah, look at the flashes. >> there and it is affecting us. >> here it comes. that is the most spectacular sight. >> if you have not seen it, you have not seen anything. ♪ [applause] fatih: hello everyone, i am acting nasa press secretary faith mickie and thank you for joining us as we look forward to the upcoming total solar eclipse on april 8.nce you will learn more about what to expect during the eclipse, how

to participate, how nasa and go eclipse to advance science and how to view it safely. today's participants include nasa administrator bill nelson, nasa deputy administrator pam melroy. nasa associated administrator, director of office of space weather operations and the nasa program eclip kelly. after remarks from each participant we will gladly take questions from the media. now i will hand it onistrator ns off. bill nelson: good morning. before we get started, we were supposed to have the federal highway administrator with us this morning. you have probably seen the emergency that is happening in baltimore.

our thoughts are certainly with them, our prayers are with the people and the families involved. i have often said that at nasa our mission is for all humanity and that is because space brings us together. there is no better proof than in moments like this, a total solar eclipse.it is a moment when milf people across north america wiln passes in front and between the sun and the earth, and it is a rare sight that we have not seen in seven years.■y and unusual things start to happen as the normal rhythms of earth are disrupted.

■6 when youre seeing this eclipse, you ought to observe this.#ó as the day appears to turn to dusk and then dark, people have heard birds stop singing. they have seen giraffe begin to gallop, roosters start crowing, and crickets chirp. so, watch for these unusual behaviors. and we encourage you to help sights and sounds around you.eclipses have. they move people to feel a kind of reverence for the beauty of our universe. their power is not only to unify us on earth, but to further

science and discovery. in 1919, albert einstein's theory of gravitational bending was proven when scientists measured how stars shift when the sun bcentury later, a total solar eclipse still brings great opportunity in science. pam will share a little bit more about how nasa missions will use this rare moment to advance science. safety is always nasa's number one priority, and that remains make sure that you have the. proper eye protection. like the eclipse glasses.

and as you look at the heavens on april 8 when the eclipse starts, please, please, put those glasses on. now, i am going to hand it over to pam. pam: thank you, sir. this is such an awe-inspiring moment. this is a very rare thing, but it just so happens that the moon is the right size and distance to cause this effect on earth.eu were talking about, sir, is completely understood by er it, because it is a miracle of our universe.re super excited.

■■■5we are incredibly excited ad have been building up to this anticipating the solar eclipse and the incredible scientific opportunities, which is my joy to talk to you about. at nasa we explore the unknown at air and space and we are looking at pushing that cutting edge of science. we really want to learn more about the universe and our place in it. the thing that is unique about a solar eclipse is that it is an opportunity to look at three celestial bodies, the earth, the moon, and the sun in entirely different ways than we usually do and scientists will take full advantage of this celestial■+ one focal point is definitely the suns' atmosphere, or the corona. so, this is a very elusive region and it can be viewed during a solar eclipse in a very special way.

it is key to understanding fundamental questions about how heat and energy are transferred out into the solar wind, which contributes to our understanding not just of solar dynamics, but also howar the solar wind will affect life on things are happening with the corona that we do not fully understand and the eclipse gives us a unique opportunity to collect data that might give insight into the future of our e chance that we will see something amazing is high. we we something amazing is high. we are also leveraging this opportunity to look at the effect of the sun on the earth's atmosphere, particularly the electrically charged part of our atmosphere that can act as a conduit for communications and navigation signals.

affects it is crucial for predicting and mitigating attentional disruptions to our technology. observing the temporary decrease in sunlight at a much quicker timescale than we experience for sunrise and sunset we are going to gain insight specifically into how sunlight affects the ionosphere. as ibodies involved to make this happen, and thanks to highly precise mapping of the moon from the lunar reconn orbiter we cannot -- we can unlock new knowledge. dotting the moon's silhouette against the sun lets us learn more about the sun itself allowing us to investigate regions like the chroma sphere. we are also going to make use of the terrain to study the sun's

shape and size and our detailed knowledge of the moon also allowed scientists to predict the better than ever before. so, in essence we are thrilled about the opportunity to conduct eclipse and we want everyone to join us in this exciting opportunity. thank you. jim: good morning. we are a few days away from witnessing a cosmic master -- masterpiece where noaa satellites will provide a front row seat to celeste teal wonder. the -- a celeste teal wonder. we/i will capture the moon's dik as it passes in front of the sun and the advanced imagers on this satellite will track the shadow as it moves of

totality. the video here shows the moon's shadow from the annular eclipse in october. no and its partners at the north carolina institute of climate studies also provided this interactive map which shows the climb a percentage of clear sky during the eclipse at all of these different locations to help people plan their viewing experience. , noaa and nasa will prepare for the upcoming launch of a satellites scheduled for june 25. it first operational chronograph, a solar telescope that logs the disk of the sun. with this instrument we will see the fainter outer space -- the faint outíer area of the sun. a smaller chronograph will be on a different observatory scheduled to laun n

2025. this satellite will be stationed one million miles from earth and positioned toward the sun where it wilt buoy capturing data from incoming space weather events. both of them will give us anece, but what you might not know that is in a total eclipse we see the corona in a way that not even corona grabs -- chronographs cannot capture. we look forward to getting the f measurements we need on a continuous basis for space-weather forecasts and warnings. thank you. ■(>> thank you and good morning. my name is kelly and i am the nasa eclipse program manager excited to discuss the ways that nasa is using the solaripin add0

satellites in the helio physics observatory that regularly observes the sun we will be using rockets, planes, balloons and on the ground1 optim eclips. the sun and its effects on the earth called space weather is one of the motivating factors in our study. although the focus will be on the corona or upper hot atmosphere as the moon blocks the brightness of the sunthe eclipse gives us the unique opportunity to research our first reaction to the sudden loss of sunshine. starting with the eclipse rocket experiment, a series of three rockets launched from wallace flights facility to explore the layers of atmosphere called the ionosphere. again that layer is important is -- as it is the one that our communications pass-through. çdi

they will sample the layer of the atmosphere to see how it changes with the sunday like -- sudden day like change. and that can help us better understand the arts atmosphere. the wb57 plane with two solar experiments will chase the eclipse getting a two additional minus totality and a deeper understanding of the sun and earth atmosphere. dozens of student teams will launch balloons along the path e eclipse to get measurements of the atmosphere. in addition, a nasa team will use citizen science is a way for everyone to join the nasa spot -- science exploration during the eclipse. highlighting three of the 40 projects that folks can participate in. the first is sun sketcher and

utilizes a smartphone to utilize -- to understand the size of the sun. the second is focused on the atmosphere called globe observers. it observes things like temperature to understand the effect of the eclipsen the third project is the soundscape where you ask for the reaction of wildlife on the eclipse and the sounds you experienced during it. these are a few of the ways to engage with the eclipse and nasa science. it is not just a stunning visual will join us in these discoveries. thank you. faith: now we will hear from the associate administrator about how nasa is bringing the excitement of the solar eclipse to you with a few safety reminders. jim: thank you. i do not know about you, but i remember where i was during the

eclipse and i'm excited about this one and i did not even understand the science. nikki fox will hold accountable. so, i'm sorry. i think the wrong remark is up. r joining us today. i appreciate the opportunity to share with you some of these things to be safeturn the adminy condolences to everyone affected. during the eclipse we want to make sure that we a n our stands on our cars. we want to make sure that we are looking out for the pedestrians. please do not just stop on the side of the road. please don't just stop on the side oth it's really important to make sure we stay focused on everyone around us. people will be stopping. so be careful. i want to make sure also we highlight the importance of the science that eveone can be

inspired by by the eclipse. it's important to look at all of the science we do at nasa. are inspired, and everyone will look to the heavens in this case with their glasses on. wer of the sun, what we do with other celestrial bods, where we're blocking out the sun. i want to mention it safety of the safety of what you need to be doing. only looking with your classes. the safety of what you do when driving. also what you need to remember about the inspiration you can r to faith. >> thank you all so much. that brings us to the q and a portion of today's conference. we have a few media with us in

the room and also the phone lines. i do ask that you please focus your question to the solar eclipse and identify to whom your question is directed. i'll start first with the media before we kick it over to the phone lines. if so, we have mics in the room for you. >> ki, -- karina bianchi -- >> hi, karina■ with supreme spectrum news. how has nasa's technology changed since the last solar eclipse? good example. in 2018, we launched the parker solar pre. in addition to everything that

experience in a week and half when the moon moves in front of the shortly thereafter, the parker solar probe is going to go in and touch the sun. interestingly, it won't touch the surface of the sun. although it is hard to determine what is the surface since there is no hard surface. it is going to touch the hottest sun. sometimes at 1 million degrees. and hopepositioned exactly righh its heat shield so that the heat shield is going to keep it at a relatively warm 87 degrees in its temperature while it is absolutely cookingn

outside of that heat shield. and we are going to measure all kinds of new things that wehavee of the parker solar probe. he has rapidly advanced and we are going to be the beneficiaries of that. >> thank you for your question. i think we will kick over to one of the questions on the phone. we have from space.com. >> hi, thank you very much for taking my question. this is for anyone at nasa. i'm wondering, will there be any plans for the crew onboard the space station to watch the eclipse or anything planned for them on eclipse day, thank you. >> yes, they will be able to see the eclipse, but with a very unique vanking up at the moon casting the shadow,

they will be able to see the shadow racing across the earth. so there is involvement and theo participate in that way. >> great. thank you. >> next question, we have jim siegel from nasa tech. >> hi, thank you for taking my question. iting event, so thank you for briefing us this morning. i think this is a question for pam or shelley. can you tell us how nasa predicts the path of the eclipse in this case across north america. how is that done, exactly? >> this is a great question. we have our scientists that work on this to predict these paths.

they have been known for a while and they come in cycles that are mathematically able to tell when we'll pass the moon between the earth and sun just right so you get the shadow cast. and based on that orientationf taking into account the tilts of everything, we can make the band predictions. an■vd then nas uses the lro, the lunar reconnaissance orbiter, there to make that map even more precise because we now know the exact pea we are tell you -- we are able to tell you how far the eclipse will project onto the earth. >> thanks. phone from ekwire. -- from geekwire. >> this question would relate

to the webcast of the eclipse. can you provide any more details on what views it will be coming from, any other activities, live activities? there a base of operations for what nasa is doing in the path of the eclipse? thank you. >> thank you. x6yes, there will be a live nasa broadcast from 1:00 to 4:00 on eclipse day on nasa plus and several other outlets. we'll have telescope feeds and■■ experts talking about the science of the eclipse and other science nasa does with the sun as well as exploration. we'll be located in 13 different sunspots. a sunspot on the sun is a place of intense magnetic activity. we are going to have some intense activity along eclipses and the sunspots along the patho also give us a different view ss

arboretum, hot springs arkansas. the noaa national parks like hot springs arkansas. we'll be in russellville, cleveland. where nasa glenn will be. anchor of the broadcast. the other anchor will be in kirville, texas where a few of festival outside as well. >> thank you. that is all the questions we have on the phone. one last check for questions in the room. that we have for today. thank you so much for joining us. to learn more about the eclipse, please visit
