Difficult but not impossible. You'd either need a new material that can handle the heat, or some kind of magnetic cushion. The real difficulty would be getting back off.

Heat?
That's an understatement.
You need to design fist a spaceship that can survive to at least an atomic bomb.

Well, landing is easy even if you can't survive the heat even for a second.

>> No.8732979

>>8732008

Even ignoring the obvious problem of heat, there's no way we could land on the Sun because there's no propulsion technology we have that can provide both the deltaV and the thrust required to counteract the Sun's gravity and slow down to a velocity of zero at the Sun's "surface". Even an Orion drive using nukes wouldn't be up to the task, we'd need something that could pull 27.5 Gs continuously just to hover close to the sun, let alone cancel hundreds of kilometers per second of orbital velocity.

We should fly a probe directly into the Sun for testing.

carbon melts at 5x10^3 K
corona is 2x10^6 K

So nothing solid will survive entering the sun's outer heat sphere.

You would need something that consumes heat to even approach, and you can think of a lot of science fiction here to suit your taste.

Why are the inner layers colder than the outer layers?

Inside the sun basically only convection occurs. At the surfaces, heat is actually radiated.

>> No.8733102

>>8733101
>>8733083
I should at to this. Temperature is actually an average of heat energy among particles. The outer layers of the sun are actually very nebulous, and only transfer heat with each other. Once the radiated heat and particles are able to escape, they have very high heat energy and can impart a lot of energy.

What would that achieve? Any communications from it would be drowned out long before it even got close.

It'd be more interesting to send one grazing through the corona, robotically collecting neat data, and then relaying to us after passing through perigee and rising away from the Sun again.

>> No.8733224

The sun isn't even solid there isn't anything to "land" on, you'd just get deeper and deeper into the surface until you're suspended in a soup of plasma.

>>8733076
The solar corona is only a hundred trillionth as dense as Earth's atmosphere though. Convection is utterly negligible and the temperature of what random occasional plasma particle you might encounter is irrelevant. As long as you have the ability to cope with the intense "5,800 K hot" radiation emanating from the photosphere (which is still no small feat, don't get me wrong), you should be alright.

Pic related is designed to operate in the outer corona, less than 10 solar radii from the Sun (and indeed, investigate what makes the Corona so hot in the first place). The thermal shield should block most direct radiation from the sun, and withstand the very high temperatures that entails, while the rest of the probe will be safely hidden from the Sun's heat in the shadow of the shield and at a comfortable temperature. While there are instruments on the probe for collecting samples of the hot corona and solar wind, the heat actually absorbed from the corona isn't even a consideration.

Well the sun exists but it's pretty small. No bigger than the moon when I look at it. And we did try to blow the moon up, so I think if they blow the sun up, and are successful then its probably the oil industry trying to make sure we rely on oil forever.

Why would they want us to rely on stinky oil

Guess it's more a question of the shape of your craft and its ability to reduce the shock front. Or you'd be able to just divert the plasma using an electromagnetic field. My thinking is the sun would probably let you spend less than a tenth of a second there, carbon can't stand much... infrared? The electrons and positrons would try burning you up? What else, holy shit maybe even neutrino interactions would gather to an actual degree of tangibility.
