Why Won't it Melt? How NASA's Solar Probe will Survive the Sun 

and use a sunscreen with 100 SFP, just in case

Use Sunglasses

Just use an umbrella to block the sun, oh wait...nvm

that's a dead idea.

An Account Just fly there at night... duh... ' hi A A... the sun is keep still activity light on... front space is a keep white light on... inside space is a dark as shadow

Simple, run your fans from much lower temps and put in some vents

because it's Motherboard And battery made by china , but I don't understand why USA won't make themselves 😐

thought old macs like mine are the only ones that heat up like hell. guess new ones do too?

@@naomiperez7482 New ones are much worse! I've owned every single MacBook they have put out they just get worse and worse. I would shift to Windows but unfortunately I'm into music and the software I use (Logic X) is only compatible with Mac.

We at NASA would be delighted to teach Apple a thing or two. Their platform is horrible.

😀

👍🏽

🙄🤔

There's no better method.

LameMonster82 ' I think it is a "literal'

White paint and carbon foam would win

a) it's not a ball of fire because the Sun doesn't burn; it's very hot gas at the surface, and corona is plasma b) white paint is ceramic and yes, it would win c) learn some physics, dork

TinyTurtle ooo watch out +Lajos Winkler This kid is 12 and is clearly the coolest

and forget it!

With that protection you can walk on the darn sun

Eric Fartman true

Now thats Massive Protection

Eric Fartman keep the tough stains out Oh wrong Comercial

gumelini1 brilliant

Cris Angelo D.C they need to do it quietly.And they need to set up a distraction right in front of the Sun.I was thinking about setting up a big speaker and playing Miley Cyrus greatest hits right where the Sun is looking.That should keep the Sun from turning over.Because if it does,well it will be "😨🌑🌒🌓🌔🌝🌡🔥💀" type of situation.

Astronomy isn't a fun ( it's fun, exciting) 😡😡😡😡😤😤

Or go at night

Kyle C now that is a great idea.Go there when the Sun is sleeping

Blu Wizard 🤦🏻‍♂️

Blu Wizard that is actually impressive. I sense sarcasm, but considering how far away the sun is, this is an impressive feat. If you were actually serious, then silly me, r/whoosh.

Peter Laing I wasn’t joking, im actually impressed.

Blu Wizard that’s a breath of fresh air. This comments section is a little loopy, so apologies for the apprehension.

I hope we don't get flying cars for common people because of the sheer amount of stupid people out there

tax dollars just becoming a liquid goo!

Haha..they're using tinfoils

Watch it not melt. FTFY

I will remember this comment

KwadGamer005 Not long it will get there

*Ba-dum-tss*

Hahaha....that's funny.

I didn't realize and it just came to me.. You know why they don't go at night? Because they cannot see in the dark.

Im dying lol

Lol great joke 😂

bro...you seriously believe them?

Elton Joel, USA has been using SI (and before SI, metric system) a long time before it landed people on the Moon. It's the general public that's clinging to an obsolete, stupid system, thinking it makes them "free" and special, when it's just making them backwards. Manned lunar landing was done with SI units working in the equations and in the computer onboard and on Earth.

It's still amazing for me that the only country capable of landing men on the moon uses ancient units.

Talk about uncultured...

Exactly! I understand the concept of the heatshield, but even when protected from the front heat and solar light, eventually the temperature of the probe will reach the temperature the environment around it... which I guess is not as manageable as she said. Can someone please explain me this?

Adrian, I am not a scientist, but your hand will reach a temperature due to an air. Oven transfers a heat to an air, an air then transfer it to your hand. In space there is no air, therefore maybe it will actually survive. Please someone correct me if I am wrong.

miami, you are correct that since there is no air, there will be no heat transfer by convection, but there will be by radiation. So although it might take more time, eventually the temperature of the probe should reach a thermal equilibrium with the environment around it

Adrian That's how you cook in the oven, at least I think so...

João Cardoso maybe the cooling system prevents that.

Woosh

Konnies Egg there is not day cycle in space, only night because night is literally space.

Jeff da gamer Mintah just replied to yourself there bud. Nice

Konnies Egg oh, it's sarcasm, my bad

Jeff da gamer Mintah no but in winter the sun is much colder so

Android Kenobi best comments ever 😬

You can be the first. Good luck

We'll most likely never walk on the sun unless we can find some super material. The probe isn't even getting as close as most people think it is. The probe will be around 4 million miles away from the sun,compared to the lowest distance from the sun that mercury takes which is 29 million miles

jimmyfly look up the car toyota corona and its real

András Ács you do know that a toyota corona is an actual car right?

Who's gonna investigate that death? Sorry

Dean Churchman it's gonna b a corona inception!!! :-)

Matej Milovanovic Cry some more about it, maybe that'll help?

Not 9 solar diameters away, but about 4.4 solar diameters away. 6.2 million km divided by sun's diameter of 1.4 million km.

From the probe, the sun's angular size would be around 12 degrees. So that's still a good chunk of your field of view, but not nearly as much as shown in the animation.

Daniel Griscom sounds cool, I would be even cooler if it was real

In a far, far Galaxy, they're using it. but no here sadly.

I have decided to finally sell my bridge. It is in London. I am taking offers. My initial market research indicates that people who believed this video are my most likely customers. Incidentally, my research also showed that these same people should not have offspring.

JAKE W JONES it will be fine

JAKE W JONES You should look for flat Earth videos. Those public is what you are looking for.

JAKE W JONES I’m not sure what you mean. I mean, the mission IS happening; you can look it up on NASA’s schedule.

Broose Waiyn yay

Yessss!

well, we shall see.

Chaitanya Singh I thought the same thing but I dont think they're gonna say "gosh darn we forgot about the solar flares oh well" after they send the probe.

I dont think it would orbit that close

It would be a shame if right after they get the probe to it's orbit a coronal mass ejection just broke it.

Edwin Tse ikr, but in the video it looked like it was right on the surface. xD

would u rather they record the millionaire nasa ceo’s laughing at idea’s that the taxpayers believe.

What is there to be serious about? Science exploration is all about cool ideas (in this case hot idea). Be casual, lay back and enjoy!

It is actually designed to be viewed by the casual viewer, hence the cartoony sounds. For more serious discussions, there are other channels. Check out 60 symbols and it's associated channels by Brady! :)

Op is a serious sciencer and nasa needs to make all their vids catered to them while everyone else is casul who don’t even kno 2+2. GtfOOOOOOOOOOOO.

I scrolled way too far to find this

@chatoiement It's not exactly a well known movie, but come on it's not that unknown. Love the soundtrack on that one.

It will either be "deployed" or "destroyed".

The testers cannot deploy it on the Earth. So the developers do some changes to the heat shield of JWST.

Well you’ll be waiting a few more years, it was delayed until 2021.

Just send the damn thing into the sun already

949surferdude Actually humans don't have rockets powerful enough to send something significant under the Sun surface. Probably Falcon Heavy can send 10kg to the Sun.

Silly Europeans, still rejecting God's systems of measurement. How sad!

King of the Moon In Science no one and I mean no one uses Fahrenheit... But this is Public information made to be understood by the American Taxpayer... Since most US Citizen have no clue what Celsius means NASA is forced to simplify things... Science communication is different, it explains Science in layman's terms.

King of the Moon There is no God by the way.

jimmyfly You think that's the issue here? I'm American and in science in general it's celcius or Kelvin. Fahrenheit maybe for Earth weather but come on, let's be real, a European will have less problems with both units thrn the undereducated American society lol

Raydensheraj ok you're cool, you can convert simple units... genuis here everyone!

"The coolant used for the system? About a gallon (3.7 liters) of deionized water. While plenty of chemical coolants exist, the range of temperatures the spacecraft will be exposed to varies between 50 F (10 C) and 257 F (125 C). Very few liquids can handle those ranges like water. To keep the water from boiling at the higher end of the temperatures, it will be pressurized so the boiling point is over 257 F (125 C)." phys.org/news/2018-07-sun-wont-parker-solar-probe.html

Water has a very high specific heat capacity, making it one of the best fluids for heat dissipation. No need to mix it with anything!

Absolutely. -The Freezing and boiling point of water was my main concern. However, I read that they're using 5 liters of deionized water, BUT, they are pressurizing the system to raise the water's boiling temp to 257F. Freezing doesn't seem to be an issue since the Sun will preheat the system into operation. ;)

Of course! Just a few bottles of Vodka and it’s good to go!

how does the heat transfered from the cooling system to the environment? Even an *air* is not good enough, let alone a void. I need to buy that radiator for my pc.

Please be r/whoooosh

Flat earth people won't complain dude... They can see the sun is circular. They lack skepticism, not eye. If they have skepticism, they'll say sun is spherical.

Palatisan No you haven’t 😂🤣😂🤣

A Town Actually, I have. What makes you think that I didn’t.

Palatisan Because it doesn’t exist 😂😂😂

A Town I took a selfie with it tho

Palatisan I’m sure you did 😂🤣😂🤦🏻‍♂️

Zach Cox I was wondering about that. Can't wait to see what they discover with the probe.

Currently the probability of a coronal mass ejection is very low, but not zero. We are currently experiencing the solar minimum, part of the Sun’s 11 year “season” of activity. This means this is the best time for a mission like this as the Sun us very “quiet.” Very few sunspots, magnetic storms and flares.

When I posted the comment above I did think about 'Solar-Minimum' and if we combine this with the expected lifetime of such probes then that would argue that it is OK not to worry too much about CMEs. So: "Slide In While Things Are Quiet And Take A Look" :)

jeeshadow yeah.. just spoiled the entire video.

Red Vanderbilt lol u got joke

and do not forget to take with you some flex tape

Red Vanderbilt yeah as simple as that

Parker Solar Probe will carry four instrument suites designed to study magnetic fields, plasma and energetic particles, and image the solar wind. Imaging the sun is already done by other spacecraft. You can learn more here: www.nasa.gov/content/goddard/parker-solar-probe-humanity-s-first-visit-to-a-star

More on the instruments: www.nasa.gov/content/goddard/parker-solar-probe-instruments

It doesn't really affect the results

It's just a math

Kittsuera There is idea they should test this device in some solar energy station with mirrors collecting the Sun light in one spot. The should place it into the spot with expected light energy flow. Then do testing for at least one day (several peak hours).

Here's the answers I could come up with, correct me if I'm wrong: 1) The whole probe isn't covered completely is because the only spot that would get heated up is the spot that faces the sun directly, so it'd be unnecessary to cover the entirety of the probe in the heat shield. All you'd have to do is make a circular heat-shield that covers the probe from direct view of the sun, and make sure it's always pointed at the sun to prevent damage. 2) No, because there's no atmosphere and ground like on earth that causes the photons to reflect and go in many directions. If you're not in the line of sight of the sun, you won't have any light and heat hitting you. 3) The radiators radiate the heat off into space in the form of infrared radiation. The required water flow to cool the solar cells and the amount of heat radiated has likely been accounted for by NASA, so they've designed the probe's cooling system based off of calculations and tests. 4) I believe they accounted for this by increasing the pressure of the water in the system, which allows the water to have a higher boiling point temperature and thus reducing the risk of explosion. 5) The electronics are already hardened to withstand radiation and other thing in space, making them water proof wouldn't really make sense. If the water system failed and exploded, there would be no water to cool the electronics and space craft, so it would be destroyed regardless if they were water proof. 6) The electronic components chosen for the mission and the solder joints between them likely have high temperature tolerances, and are likely to be very reliable for space flight applications. I hope this helped answer your questions!

Kittsuera 1) money and weight. Heatshields are expensive and heavy. 2) the light from the sun flies out from the surface and away from it, meaning there would be nothing to reflect off of and onto the spacecraft. 3) the water is kept under pressure so that the boiling point raises above the ambient heat of the surrounding area. Water is a very versatile cooling system. 4) I dont work with NASA so i dont know, as i said earlier, water is pretty great so i dont think they would do such a thing out of sheer will. But who knows? 5) the spacecraft is flying towards the sun through space. If it can withstand a vacuum, it can take water. 6) NASA knows what theyre doing, last thing I expect is for them to underestimate the heat of a giant ball of plasma 1000 times more massive than our entire world.

I still for see a slight problem with my # 2 point. the Sun is about 109 Earths wide. will light really be radiating in one direction perfectly Vertical from every point on the sun? What is stopping the far ends of the sun from radiating light diagonally?

Well for arguments sake we assume that the sun is large enough, and that the probe is close enough, for you just to think of it as a big flat plane emitting light. This is the worst case scenario as its actually curved and some light will be shining diagonally above and below the spacecraft. If we go back the plane, the light it emits is radiated out from the plane, perpendicular to it. Then some of it is blocked by the heat shield leaving whatever is behind it in shadow. This shadow does converge at and angle yes, but it's certainly been calculated by NASA for operating distance of the probe. Hence why the main bit of the probe is a lot skinnier than the heat shield. Just look at planets for an example, one half is bright, one half is dark and in shadow. And because there is no atmosphere to scatter the light the shadow is pure shadow and actually extremely cold. You ask what there is to stop the sides of the sun radiating light sideways/diagonally towards the spacecraft? For one theres physics, most of the light/radiation is shot off perpendicular to the surface. The reason we get such effects here in earth is because of the atmosphere scattering light. In the case of the sun its just flung outwards with the solar wind. And it some were to be scattered towards the probe in some way it would likely be too weak to effect it much. Also the probe could be orbiting too close for that to be a factor. The closer it is, the less the bits of the sun not directly in-front of it, can effect it. As is you drew a line, from its point of origin on the surface, it would have to go through more of the sun itself again. Just take a circle and put a dot representing the probe right next to it, see how many lines you can draw to it from the surface that dont go into the circle itself, its rather limited. And that the worst case scenario for radiation from the sides of the probe. Hopefully thats cleared some bits up! :D Sorry its a bit long, I think I've rambled.

I'm typing this on a MI phone lol.

It won't be that close to the sun. I will be about 4.4 times the diameter of the sun away from its surface.

We are currently in the heart of the solar minimum. There are very few flares occurring right now.

Highly doubtful! A probe doesn't have an atmosphere like earth. Earth is situated at a perfect distance from the sun with a magnetic field which disperses the solar flairs. Also acting as a faraday cage to stop global electro magnetic pulses (blackouts).

Sun-Kissed 😬

Well, that won't happen. You can imagine everything if you want, but keep your insulation dealer at hand, because that probe will: 1, get closer and closer to the Sun 2, and melt into a red, then white ball 3, then evaporate fairly quick.

Lyvlon Well, why don't you ask them about it?

Even near the sun, the solar wind pressure is extremely low.

My3dviews Um I don't think so! According to the equation of the solar wind pressure, the proton mass, the density in the solar particles and the speed of the wind, they all get higher when the pressure gets higher. When you're close to the corona, you experience the "fast" solar wind, which has a velocity of 750 km/s, while near earth, it's average of 400 km/s. So the pressure of the wind near the sun is much higher.

+Celtic 67 The pressure of the sun's corona is a fraction of the Earth's atmospheric pressure, since it is made of low density particles (like protons and electrons and some alpha particles), not heavier ones like Earth's atmosphere. The solar wind is made of these low density particles that escape the upper corona. They escape because they are far enough away from the sun where gravity is lower. scied.ucar.edu/solar-corona

+Rogy Mahmoud You need to take into account the extremely low density of the corona when making calculations of its pressure. Single fast moving particles like protons and electrons do not produce much pressure even at high speeds.

Celtic 67 lol bc science man. Its whatever they want it to be

Yep ..Sunshine ..Movie involved thorough emotions

Literally in my top 3 favorite movies of all time since I was 10!

"Sunshine" - cool looking movie with very bad plot holes.

There's been other spacecraft.

Short version, they use radiation profiles during a solar eclipse (which blocks basically everything but the corona). Long answer, here at Cornell Archives arxiv.org/ftp/arxiv/papers/1112/1112.3850.pdf

Ever heard of mathematics and laws of physics?

cleisz torrefranca, flying close to sun is not like apple falling down from tree, ever heard about perturbation ?

iani_3d so, you're thinking that laws of physics combines with mathematics is just about the analogy of apple falling down the tree. Do you even know how wide physics is?

It's both. The sun emits a continuous spectrum that peaks around yellow. And by measuring where this peak happens, we can even predict its surface temperature. en.wikipedia.org/wiki/Black-body_radiation

Oh Hi dear

It is white but, society, culture and, tradition has mostly viewed it yellow since that’s the wavelength we see from earth during the day. That’s why most CGI or cinematics, regardless of accuracy, like to make the sun yellow instead of white.

Diego Llamas :Yep. Apperently it appears yellow because some of the wavelength is abosorbed by the blue sky. If you add the blue back into the yellow sun, it looks greener. Although due to its intensity, our eyes will see it as white. Evidence of a green sun exist in plant leafs. They are green to maximize the amount of radiation absorbed for photosynthesis.

Diego Llamas thank you and CitedHarbor0 for that wavelength and leaf fact!

Tletna Because the heat shield probably weighs a lot, and the less mass you spend on shielding, the more you can use for science stuff.

It only needs to shield itself from the solar radiation of the direct sunlight, which would damage the probe. Shielding it on all sides would prevent the instruments from measuring the solar corona, which is the whole point of the mission.

This shield reduces termal energy flow. But it is still not zero on the other side of the shield. So making ball of shield does not have any sense for the electronic devices. Ball shield will be heated to the maximum temperature, and all inside will do the same.

Because the heat will be coming out from the sun.
