So I just completed a flight. I was developing a 5t launcher and for the payload I had a Mk 1 Pod, two Mk2 Radial parachutes, a service bay with some batteries, mecjeb etc, fuel, engine, RCS. Then on top of the pod I put a small separator, a heat shield, a larger separator and a nose cone. After getting to orbit, I got rid of the nose cone, freeing the heat shield. Then after braking burn, turned pro-grade. I watched the temp of the radial shutes and they never went above 500C. Only odd thing that happened is that when I deployed the shutes, one of them said it could not deploy while stowed. It was on the side of the pod, well away from the storage bay and at the same spot as the other shute. I opened the bay doors and then I could deploy. Seems like a bit of a bug, but shows that you can probably put a parachute in a storage bay, then open the doors when you want to deploy. So my rocket was a bit more complicated, but still works. I actually enjoyed the challenge to get it right. Now I have to figure out how to bring a Mun lander back to Kerbin. Either that, or do an Apollo style setup with a lander, command pod combo. Would be fun to try. That and a space station with a mobile lab to process all the science brought back.
