RSS Earth Reentry

[dino1984]

I am trying to bring back my capsule with two material bays and service bay, but as soon as I go into 60 km I lost control over this thing, it starts to flip and all except capsule burn...

Do you know any idea to reentry something more than just a command pod?

It is early stage of game, I unlocked just 3rd level of tech tree.

My flight is suborbital KSC->north pole.

Unless you have unlocked heatshields your pretty much stuck with either avoiding re-entering the atmosphere or doing large retrograde burns with an engine to slow you down.

The way down works exactly the same as the way up. Meaning, if you want your spacecraft to stay pointing in a specific direction, you must follow the golden rule:

"Heavy bits at the front, draggy bits at the back."

When you have a pod with two science bays and a service bay, the pod is the heavy bit. But the bays are mounted "in front" of it for the purposes of reentry. Hence, the spacecraft seeks to reorient itself so that the heavy bit points forward again.

Three potential solutions:
a.) Mount something heavy inside the service bay, so that the bay as a whole becomes heavier than the capsule.
b:) Mount something draggy (fins) on the capsule, so it is encouraged to stay at the rear. You'll need to enclose your spacecraft in a fairing, or you'll flip during launch instead.
c.) Don't use a capsule. Use a probe. Mount it inside the service bay for good measure.
