Heat mechanic and our Sun (Kebrol)

[1greywind]

Does anyone saw in preview stream people tried to test, will ships evaporate from going to close to Sun? Does Kerbol radiates same sort of heat that reentry does?

[EladDv]

probably but today you could also blow up from the sun's heat so nothing changes

I think the point is: Can we now using heat shielding parts to get closer to the sun?

No, Kerbol is just rendered as a planet like all the others. Temperature is rendered by distance from it IIRC.

If you get to close to Kerbal, the ship will explode.

Well, there's this from the release notes, which is fairly promising:

"Celestial bodies now accurately emit thermal radiation that makes nearby craft warmer."

Although it's hard to tell specifically if heat shields actually work on this kind of heating, but it sure seems like it since occlusion is actually calculated.

Solar flux is modeled. Orient such that minimal area is pointing towards the sun and maximal area away.

Nice.

Not away, but perpendicular to the sun. Max area away, as in 180*, would mean an equally large cross-section point towards. You want the big flat bits pointing towards space 90* from the sun.

And polished shiny bits towards sun, and dark rough bits in the dark ... that is if reflectivity is modeled.

Since were nit-picking, area facing away from the sun doesn't necessarily imply 180° away. Perpendicular can be considered "away" as well. Also if you're going to use an asterisk you should always include a footnote with it :]. (Just being cheeky!)

<Fist bump to NathanKell/>

[NathanKell]

I did indeed mean "dot <= 0" by "away"

Actually theres a post about new Heat Mechanics right here http://forum.kerbalspaceprogram.com/threads/118192-1-0-Cooldown-A-Community-Discussion-of-Heat-Management, and also it models the black body radiation so darker parts will be useful going straight into the sun in a perpendicular position to it
