Yeah re-entry heat doesn't seem to be a big deal. I've had some fins break off but that's about it.
But, speaking of re-entry, I was trying to do the research mission for testing the Flea Booster in orbit. First of all, for some reason getting that thing into orbit was way too hard. I mean, I guess it's heavier than my normal payloads to this point, but sheesh. I tried to use the Stayputnik to lower the mass but for the life of me I couldn't make the rocket stable. Anyway, eventually sent it up with a manned capsule, which got the pilot ranked up to one star and gave me a bunch of options for orienting the ship in SRS. Sweet!
The problem was that while planning out my de-orbit with the Flea, which had to be fired at a certain altitude, I left my pilot in retorgrade mode which caused me to unwittingly drain all my electric power and lose all ability to orient my ship. Not good.
Eventually I went on EVA and figured out how to use the suit thrusters or whatever. Though not before losing sight of my ship. Figured out that you can target it to see, rendezvoused with it and began ramming it until it was on an orientation that I liked. That took a while. Fired the Flea at the appropriate time to attempt to deorbit, and to complete the mission. For some reason I didn't get credit for testing the rocket. Maybe I had drifted too high before I had actually engaged? I don't know, but that thought instantly got pushed away as the Flea sent me tumbling all over the place, provided no useful burn, and left me in orbit stranded.
So I figured, what the heck, if I were stuck in space like that, and knew no rescue was coming, what would I do? Of course I'd try to re-enter the atmosphere and go down like a shooting star. That's way classier than an orbiting corpse. My periapsis was only like 72k, and sure enough, a very minor amount of propellant was enough to point me at the ocean. Didn't burn up on re-entry, for good measure I burned the rest of my propellant vectoring up until I splashed down in the ocean at maybe 50m/s, apparently none worse for the wear. I guess those kerbals are a lot sturdier than I gave them credit for.
But sorry Jeb, you're going up on the same ill-designed hunk of garbage as last time, because you have a mission to complete.
