Sundiver design tips?

[MaverickSawyer]

Has anyone ever done a successful (in close and back out again) Sundiver probe in 1.0+? I'm curious to see what tricks you use to mitigate the heating...

Okay, a few tips and observations from my own experience at this...

-Ablative heatshields are pointless. The ablative will bake off two days before PeA.

-No matter how small, do NOT put any solar panels out into the light. PERIOD. Run on an RTG, some scary huge batteries, or fuel cells for the fryby.

-The conformal, passive radiators are not very effective at all. Use the deployable ones if at all practical, or wait until Nertea's Heat Control Pack is back up to speed.

-Shadow shields are a MUST. If someone ever creates a reflective one that bounces the heat off before it absorbs it, that'd be the ticket.

-Structural stuff is gonna get glowy down below 350000 kilometers. Plan accordingly.

-I strongly advise a MINIMUM maximum temperature rating of 2500 Kelvin for ALL parts.

-Whatever you use as the shadow shield needs a maximum temperature of 3000 Kelvin, and should have a radiator attached directly to it. (BTW, this rules out the stock 2.5 and 3.75 meter heat shields.)
