It's done actively via the reaction wheels. They use rotation (gyroscope effect) to stabilize and adjust each axis of the craft. They're mentioned and shown in the video at 2:20.
The shield could have been made a curve rather than making it flat, so that it could scatter a large fraction of light waves. That could also increase the surface area perhaps. Anyway it is already been doing incredible job. Hats off to the scientists.
Very informative and excellent video. Is there any heat transfer due to exposed portion of some instruments behind the Heatshield into the probe due to Conduction ?
So the heatsheild is a sandwich of carbon-carbon composite then a carbon foam and then another carbon-carbon composite. Carbon-carbon composite is carbon fiber embedded in a carbon matrix. So it is "CARBON!!!"
Diamonds are carbon too, but they sure as heck arent good thermal insulators. I quite liked the emphasis they put on correctly saying all the carbon based components the shield has
What's the flame temperature incident on the carbon foam you're showing? And it's about one million degrees centigrade in corona so how does this carbon foam respond to million degrees centigrade temperature?
2500 Fahrenheit on the front face? 1370C, or 1645 Kelvin. That is well past yellow hot, approaching pure white hot. About *exactly* the melting point of mild steel.
Okay now that I have some time... getting back to my own question.... So using small angle formula: Given: Dist = Distance from probe to sun = 6,000,000 Kms. Dia = Diameter of Sun = 1,392,784 Kms. Pi = 3.14159 Find: Theta = Angular Diameter from probe. Dia / Dist = Theta / ( 180 / Pi ) 1,392,784 / 6,000,000 = Theta / ( 180 / 3.14159 ) 0.2321306666666667 = Theta / 57.29582790879777 13.300188 = Theta = Angular Diameter from probe = 798 arcminutes Woahh!!!!! 798 arcminutes is HUGE!! Hypothetically if you could safely sit on Parker Probe when it's closes to the sun and look at the sun; the sun would look as big as your fist on extended arm. Just wow!
My guess is that aerogel's insulation is based on air being trapped inside the gel lattice, and in the vacuum of space that air would seep out, rendering the gel useless. Thus, they need a material whose insulation is not based on trapped air.

this is the best probe specific videos I've seen.
Carbon foam. Guess you can't burn something that is already burned...story of my life.
Fahrenheit? Do you measure the distance to the sun in hand spans too?
In the description you will find it in Celsius.
Why? Are you confused by any measurement that doesn’t require you to count your fingers? Cause that’s where bass ten comes from.
Not necessarily, 10 fingers isn’t optimal for everything
In imperial (neanderthal) units, an astronomical unit is 744 million furlongs or 2.97 billion rods.
Millimetres to Meter: 1000 Inches to foot:12

Hey! A fellow Patrick! And he's a scientist! What a time to be alive!
What is the “white coating “ made of?
Aluminum oxide.
Shame NASA failed to use SI
I would assume they use SI internally, as is the standard in the scientific community, but these interviews are aimed at the greater (US) public.
Yet it’s NASA sending this probe. Sure seems to work using their measurement doesn’t it?
What keeps the probe from rotating and the heat shield facing the wrong way exposing the wrong side to the sun? Very fascinating indeed
Mass Distribution / Center of Gravity... Makes sense for me.

thought the same
From what I gather, yes but minimal
I guess everything coiled by cooling radiator, and it is 85F at the back..
I always wished i could work on things like this in some small way.

Carbon sandwich with carbon filler. 100% chocolate Oreo. :-)
so it's basically a sun-baked sandwich
What's the flame temperature incident on the carbon foam you're showing? And it's about one million degrees centigrade in corona so how does this carbon foam respond to million degrees centigrade temperature?
At closest approach, the probe is “coming within 5.3 million miles (8.5 million kilometers) of the solar surface.”
It has become the most successful mission in space by mankind.
Thanks to NASA
Not even close to ruclips.net/video/iIvgoac4o_A/видео.html
Just brilliant design. But I’m curious why they didn’t mention the bone ground up in the heat shield used because of its heat reflective properties.
This is great innovations

Great parkar solar prob video
Bruh When we send parkar solar probe to Proxima century?
superb explanation
They are using a million, thin, 4 by 8 panels with 4 million seams. Never understood the shield in the movie 'Sunshine'.
Great job! Is that heat shield material descended from the tiles on the shuttle?
But what about the sun gravety
why not aerogel?
What would be the angular diameter of sun when the Parker Probe is at perihelion?
Okay now that I have some time... getting back to my own question....
So using small angle formula:
Given:
Dist = Distance from probe to sun = 6,000,000 Kms.
Dia = Diameter of Sun = 1,392,784 Kms.
Pi = 3.14159
Find:
Theta = Angular Diameter from probe.
Dia / Dist = Theta / ( 180 / Pi )
1,392,784 / 6,000,000 = Theta / ( 180 / 3.14159 )
0.2321306666666667 = Theta / 57.29582790879777
13.300188 = Theta = Angular Diameter from probe = 798 arcminutes
Woahh!!!!! 798 arcminutes is HUGE!!
Hypothetically if you could safely sit on Parker Probe when it's closes to the sun and look at the sun; the sun would look as big as your fist on extended arm.
Just wow!
That doesn't seem to be that big (to me).
Distance to sun about 1/24th AU
5:14 I can see James web space pic... now its already launched perfectly...
Congratulations
Is it a better insulator than aerogel? Or its just better at high temps?
My guess is that aerogel's insulation is based on air being trapped inside the gel lattice, and in the vacuum of space that air would seep out, rendering the gel useless. Thus, they need a material whose insulation is not based on trapped air.
Excellent!! 👍
Good job guys
Angular diameter of Sun will be 12° in closest point. Not 90° as you could to think.
I love it😀😀😀😀😀😀
Nice and cool in the back, the same shit would happen in a block of concrete
Are we getting pictures of the sun from this probe?

SciNews Thanks
Good for building material
Not cost effective for that application, I would think
Really poor quality microphone pickups used for this article
what kind of money do people on this project earn
International Units, please!

En mí opinión ésa placa es magnetica de alta densidad.. para rechazar el campo solar.
that's not how in the Sunshine movie... :D
😍😍😍😍👏
omg if I looked at that truss and someone asked me how heavy it was I'd guess 300+ pounds lol
👌👌🎉
En mí opinión sólo una órbita,en la segunda muerte sistema...es para 2022..
Dad be like “fake don’t watch these stuff it Melt it”
En mí opinión ésa placa es magnetica de alta densidad.. para rechazar el campo solar.ay dos fuerzas directa.
Are you even real? Escribes como un robot, no se te entiende.
Powered by arduino.
Okat
It doesn't have to be rocket science 😐
Bogus
Should be solar powered
very poor video. almost none explanation...
Mga kano talaga ano gustong patunayan sabayan ang talino ng diyos, naku po naman di mabubuhay ang tao sa araw.
Marami tayo matututunan sa ginagawa ng mga engineers tsaka scientists ng NASA. Hindi naman nila hinahabol ang talino ng 'diyos' na tinutukoy mo. Mas marami tayong matututunan sa pagaaaral ng mga stars kesa sa pagbabasa ng bibliya.
ikaw nga wala pang napapatunayan eh lakas mo maka ano.
