Help.
My Rocket has 1134m/s DeltaV (Terrier Engine), but that's not enough to safely slow down to land on kerbin. At my periapsis I'm going more than 3000m/s, and I have no electricity to use reaction wheels for stability. I've tried many times to dip into the atmosphere over multiple passes, but eventually I hit ~30k and have to land, but I don't have the fuel to slow down enough to deploy parachutes, or any electricity to use reaction wheels to remain stable while using the heat shield to slow down. I am wondering if there is a way to get electricity to my ship, or save Jeb and the tourists in some other way...
I'm really stuck. Is my best option to try and deliver electricity in a battery or something? using another kerbals inventory? I was thinking about sending a kerbal up with the battery, then having jeb get out and retrieve it, but idk if that power will be useable. I haven't tried this before. If a battery is in the inventory of the Mk1 crew cabin, will it power the reaction wheels?
I've got some ideas, and I might be able to do it, but I am hoping for a better solution.
(I don't have any save states within reasonable time before this mission, I'd have to lose heaps of progress if I were to revert to an older save... Safe to say that I've learned a lot about planning ahead with this mission haha.)
Thanks in advance for anyone who offers help :)
