OK, current technology in the sense of heat resistance etc - But use your imagination that we could fire a human toward the Sun in a ship that would only burn up once it go too close to the Sun itself.

How close could a human get to the Sun before it was too physically hot and we just burned alive? Could we get closer than Mercury for example?
 
Copied from wiki,
Mercury's surface experiences the greatest temperature variation of all the planets, ranging from 100 K (−173 °C; −280 °F) at night to 700 K (427 °C; 800 °F) during the day at some equatorial regions

You'd be OK in Mercury's shadow.
 
Just what. Troll or total nonsense.

Have you got any idea how hot it is in space when in the sunlight, even on the moon.

In direct sunlight in orbit you can reach 135c, which is why space suits are white AMD insulating. Not just for the cold but the heat as well.

So somewhere between ground level and space in direct sunlight.

So why don't astronauts come back to Earth with a nice tan then?

What an odd question. So you think astronauts just float about in space in their birthday suit.
Either in a can with cooling/heating, or in a big space suit designed to jeep them alive.

On the Apollo missions especially when the dust guard broke on the rover they had to be careful about how much dust they got on them and brush it off, as it absorbs far more energy than there white suits.

So why didn't they bring the dust back to Earth with them so we could use this energy? Or is that what the Chinese are after now?
 
I assume astronauts use something like suntan cream but obviously with a MUCH higher factor. Not something we could buy from a shop.

Must be like putting thick cream on your skin.

:D

Well considering it can get to over 100C on the moon in direct sunlight - and the sun's coronas can hit over 1million C. Though the sun's effective temperature is "only" around 6000C IIRC.

You can get quite close, I saw a documentary about it. Their ship had a big viewing room to see the Sun but they had to wear special shades.

yeah think i saw that one as well

they also had one a week later where they took the ship and kinda did a sling shot thingy. They mentioned something about extinct humpback whales.
 
Apparently... "we could get within 1.3 million miles of the sun but the integrity of the shield degrades rapidly above 2,500C, and the cockpit would begin to cook."
