NASA launched its $1.5 billion Parker Solar Probe this morning atop one of the most powerful rockets in the world to study the mysteriously powerful atmosphere (called the corona) of our closest star, the sun.

The car-sized spacecraft will fly as fast as 430,000 miles per hour (making it the fastest human-made spacecraft ever ) and will orbit the sun about 24 times over the course of its 7 years journey towards the sun.

During the journey, the probe will swing around planet Venus 7 times, using the it's gravity to push it closer and closer to our star until it comes within 3.8 million miles of the solar surface ( the closest of any spacecraft ).



Even though the environment the NASA spacecraft is travelling to is unimaginably hot (greater than 3million degrees Fahrenheit ), it will not melt.

See The Reason Why NASA Spacecraft Won’t Melt below?



It’s like the difference between putting your hand in a hot oven versus putting it in a pot of boiling water . In the air of the oven, your hand doesn’t get nearly as hot as it would in the much denser water of the boiling pot.

So despite this extremely hot temperature, the probe's surface will only be subjected to roughly 2,500 degrees Fahrenheit .It's thick heat shield and the water-powered cooling system will also allow the internal measuring instrument to remain at just 85 degrees Fahrenheit.



The corona is important to study because it is the source of solar flares and other forms of space weather that can disrupt our technology (like the electric grid and telecommunication satellites) and take us back to the stone ages.

Scientists are trying to understand why the corona (which has temperatures reaching millions of degrees Fahrenheit) is so hot and even hotter than the Sun's outer surface (whose surface is more like 10,000 Fahrenheit or 5,600 Celsius)

NASA solar physicist said:
“We know it’s due to the magnetic field that connects the Sun’s surface to its outer atmosphere, but we’re still learning about how [energy] gets out of the magnetic field into the corona"

Oh God, if America is doing this through NASA .... A technology exploring the sun
Here in Nigeria, we can't even afford political stability nor even imitate a technology that can re-explore the moon .... Africa Oh Africa, Sub Sahara Africa oh Black Continent .... Will we ever rise as a continent like this

Cool...

The SUN, the closest Star to the Earth

$1.5 billion just to study the temperature of the Corona..
Na only this countries education get sense, but for here in Nigeria "education na scam" for a first class to be earning 19k as salary.... (story for another day)

Meanwhile, watin dey worry this gringos self, the Corona don dey that place jejely for many centuries doing watin he sabi do... Make dem no draw watin dem no fit carry ooo

am learnin a new lesson

Was on front page yesterday during Explorer thread

Is this different from explorer thread ?

why are we deceiving ourselves, it is better we concentrate on our cassava production first. How many Nigerians professor in engineering understand this? Even common bicycle, our prof in engineering no fit fabricate. Nonsense.

I hope it will endure the furry of the sun?

This is massive

so they finally know how to make heat shields,but I trust the sun to do its job on that spacecraft.

The last time I checked, they didn't have the money to go back to the moon.

7years in space...and we are here dragging bad roads and erosions.

430, 000 miles per hour speed

No comment

$1.5 Billion to explore sun surface when man never see good food chop for this country. Just tell me why being an African is not a curse? Do we really have any purpose here in Africa other than envy, strife, wickedness and evil.







Dark continent!

This is why the white man evolves, always searching for new horizons. The Black is ok with just 1billion stolen funds is his akant for no exact purpose

And afta we would want to compare ourselves with d West... We have been driving in reverse while dey seem to have finished all d drive gears ... We are still struggling with issues as basic as power and infrastructures while dey are thinking of other planets...

Help me ask dem oo

The sun don't shine forever but as long as it's here,we gon shine together ⚡

Tomorrow make una dey compare Una self with oyinbo. Hope you all have seen for yourselves now. Nigerian can only achieve such feat in the year 9090

Engineering is sweet.... How I wish Nigeria appreciates us the way it appreciate politicians.....

Blacks were not designed to think (devise) with their Brain ,but it can store (cram) anything...

Blacks are only good in buying and showing off

430,000 miles per hour. Nigeria must be moving at a speed of 100km per year.

Like if you agree.

When you are not hungry, your brain goes to work.... This is typical of why things are invented there. Go there and you will be surprised to see that blacks, Africans are behind the breakthroughs. All we need is food on our table, a favourable environment that will enable us put our brains to use at full capacity, is it too much to demand this from our leaders? Soon the youth will buying and selling votes instead of demanding for good governance.

This is just awe-inspiring. In this part of the world, we don't even produce toothpicks and matches.

lol, Definitely we were not created by the same creator with the whites, we are like the refurbished version of human being. A lot of things are missing in our DNA, I think we are like a test subjects to bad invention.

Give a black man such among of money or resource, first thing that comes to his mind is to "Buy 30b Worth of car, build mansions all over the planet, fill up all the mansion with flee of cars, lavish excessively on oloshos, and intimidate the poor and make them worship him for a penny.
That's what their thoughts can process.
Unfortunately consciously or unconsciously I'm infected with such disease too. what a pity.

Compared to the 1st World, the developments in my country can break one's spirit. Those guys are 'probing' the sun while we here are engaged with innovations like cattle colonies (not even ranches) amidst religious extremism, primitive accumulation and politics characterised by tomfoolery and thuggery.

Do not be fooled. If I tell you the number of homeless people on the streets of US cities, you would be alarmed. On the road, under bridge and even close to city centers. Both black and white, but more African Americans. Each time I see an homeless man on the street begging for money I wonder how on earth a country could be giving out billions in aid, spend hundreds of billions on military, and space program but can't afford to take care of all it's people.

Bro, u 4gt to include suffering, greed nd Ignorance to your list. Truth to be told one's must not live his entire life in Africa and still end up in Hell...

Light

Light will be there in approximately 8 mins
