- Professor Mark McCaughrean joins Iain Dale to discuss the NASA spacecraft attempting to make history with the closest-ever approach to the sun.
McCaughrean is an astronomer and former Senior Adviser for Science and Exploration at the European Space Agency.
He explains that Nasa's Parker solar probe will race past the sun at 435,000mph - fast enough to travel from London to New York in 29 seconds.
The unmanned spacecraft will be 3.8 million miles away from the sun, within the corona, or outer atmosphere.
Parker's exterior temperature will rise to 1,400C and its electronics could be destroyed by the intense heat.
Scientists won't know if the spacecraft has survived its ordeal until it signals back to Earth on Friday.
Parker has been in space since August 2018, and this is its 22nd orbit of the sun - and the closest it will ever get.
Scientists hope that the spacecraft will send back a huge trove of data that will help them understand the sun better.
In particular they want to understand why the outer atmosphere of the sun reaches 1 million degrees, but the surface is only around 6,000C.

'Is there a gravitational pull from the sun?'
😂😂😂
If he'd just gone with it and been like 'na' 🎉
And these people are so called journalists
😂 quite certain that he answered that question earlier but guess Iain was thinking of his Xmas dinner so missed it
I think he meant how many times the force of earths gravity would be felt if you were in the same place as the probe. Sadly the answer is easy its 0 due to its speed. But if stationary it would be millions more than earth but you would fall right through as there isnt a solid surface to stand on
Next on Iain Dale. Is water wet?
😂
Water by definition is not wet.
Wetness is a scientific definition, the degree at which a liquid state of matter adheres to a solid state of matter.
Water being the liquid has no implicit wetness, but in contact with certain solids may display a certain degree of wetness.
😂🤣😂
Iain, do try and learn some science... 1:26 Give me strength.
sometimes host ask questions he already know in order to educate the audience just in case the audience might not know or are interested in it
Bless him 😂
@@James-h9l err the fact that I'm typing this reply on my home laptop using the internet and WiFi, and it is being sent to servers around the world via satellite or terrestrial communication, and affords you the ability to make your comment is either in support, or lack of support for your point, I guess? I'll let others judge...
@@ElGordo1959 yeah but besides the technology, the medicine, the life expectancy, the food, the education and the overall quality of life.. what have the scientists ever done for us?
@@TheHumanTheory 😂
What a telling and depressing triptych of questions - "Does the sun have a gravitational pull?", "What's the point?" and "How much did it cost?" We're in such trouble.
Hi I’m a really thick journalist and have a question
Is there a gravitational pull from the sun. Ffs
OMG.
"How much does this cost?"
Why is this always asked with the greatest tsk tsk of tones whenever space science does something amazing? Far better this than some more missiles.
Should just have gone at night time, would have been much easier.
😂😅
Did a journalist seriously just have to ask if the sun has a gravitational pull?
Off course it's to educate us? Isn't it we are the sheeple are not
I think Prof. McCaughrean did well to keep a straight face and not roll his eyes when asked whether the sun has a gravitational pull.
Gravitational slingshot... Michael Andrew Minovitch ( c. 1936 - 16 September 2022) was an American mathematician who developed gravity assist technique when he was a UCLA graduate student and working summers at NASA's Jet Propulsion Laboratory.
'Whats the point of increasing knowledge and understanding the natural world?'
It's not like any insights and curiosity of the real world gave us anything worthwhile. Other than electricity, modern medicine and the &^%*( invention of radio and tv that their livelihood is dependent on.
The Andromeda Galaxy is hurtling towards us at 68 miles a second. I want to know what Keir Starmer is going to do about it??
Brexit was the solution bojo is a visionary
That's nothing. The speed camera clocked me at 500k mph and it was just a 30 zone :)
Flat Earthers are apoplectic with rage 😂
They'll have some conspiracy to explain how it's not happening.
Why would it bother flat earthers,don’t they specialise in the earth and not the sun,surely they would be called flat sunners if this was the case.
@@Philshki82they think the sun is much closer and doesn’t have anything to do with the orbits of other celestial bodies in the solar system. Surreal levels of smoothbrain.
Did he just ask if the sun has gravity 🤣🤣🤣
I am sure he asks dumb questions on behalf of the viewers and that worries me more than another Carrington event.
I'm with you on that. I didn't need his question but then again I was educated in the 60's and 70's.
It's weird that they never ask the same level of questions when talking about sports or politics. "So you play with a round ball? Is that true?"
Send Starmer up in the next one!
Found the Tory/deform “fluffer” /
I hope they soon have the first man to walk on the Sun
I believe stazi has his name down. Not sure if he volunteered or some country put him forward.
@@Penfold-8521 A brave person. A hero perhaps!
Its all to do with the gravitational pull to speed up even i know that and i have no qualifications
I remember as a boy hearing and reading about probes using the 'slingshot effect' around Venus or Jupiter.
That was over half a century ago.
Parkers going to come back with a suntan:)
Amazing technology ❤
The ‘Term’ is actually “MAN MADE” Not human made…..We are all Humans, and seeing as Animals aren’t capable of building and launching Spacecraft into Deep Space, it’s a pretty pointless statement isn’t it….It is a Generic term that also includes Women….And besides, ‘Human’ has the word “Man” in it anyway!
OK Karen.😂
How much did the probe cost? What a silly question. The scientific illiteracy of the average journalist has been a problem for decades and it isn't getting any better even when the world is getting more and more complicated. But journalists still spend their time learning politics and law thinking that's all they need.
Well, well. Iain is scientifically challenged.
Technically, there is no gravitational "pull" from the Sun, or anything for that matter. Gravity is the curvature of spacetime caused by all objects with mass. This curvature makes objects come together, hence why light, which has no mass can be affected by gravity. I'm guessing this isn't what the presenter meant though when he asked his really insightful question.
And objects don't have weight, they have mass. They are not solid, atoms make up everything.
You are correct, but you're being pedantic. This is an interview aimed at the layman like me
@@neilgodwin6531 fair point but I'm not trying to educate, I'm merely aiming a joke at the presenter. A joke that could be interpreted by and hopefulll add a little cheer to, somebody who knows a little about general relativity, which you clearly do, you're not a layman.
Electro magnetism is the true science. We are sold lies every day..
That is such a 3 dimensional way of looking at the 4th dimension.
Its been said in some quarters that an extreme Carrington type event is likely to occur in the years leading up to 2029 or a few years later. TH-cam Jerry Kroth - The Collapse 2024-2034
interesting video
Incredibubble 😮
The question "Is there a gravitational pull to the sun" should get this "presenter" immediately sacked. No wonder the world is struggling when we accept the most ignorant ppl broadcasting stupidity to the world. He will be questioning how to grow concrete next like the other dullard you employ?
Hi there is a new somalilanader country
NOBODY=
NASA= We finally touched the sun!
NASA AGAIN= We were only 4million miles away from the Sun’s surface.
NASA AGAIN= That’s less than a football field away from the surface.
Normal people= 🐂 +💩
Hope it’s got Elon musk inside
Iain Dale said Jesus Christ existed like it was an historical fact. Its not a fact, Mr Dale. The Jesus of the Gospels is midrash story telling. Its not history.
What load of bs
Perihelion 22 successful.❤❤❤
This scientist is behaving like a compulsive agitated liar under duress. I think he's a nasa patsy.
Yikes. Stay on the meds.
He's making it up.
He's watched too much Star Trek. I wouldn't want to get sat next to, on a long haul flight with this dull bottom burp
There were no mobile phones in 1859.
Pure gold.
Why would he make it up?
@@GWTH-Riches When faced with questions like "Is there a gravitational pull from the sun?", what do you expect?! He tailored his response to the level of his audience, as one should.
"He's making it up"?
Please tell me you are not a Flat Earther....
