Wow just had a harrowing Mun orbit mission because I forgot TAC Life Support makes you require Electric Charge. After quite a few quicksaves/loads to figure out exactly how long he could go without, Bill finally returned safe and sound because of a stupid number of "lets not die" burns at periodic intervals.
So yeah, Orbiter III has four batteries and two solar panels due to this.
EDIT: And now ladies and gentlekerbals, I give you something astounding that has never been done before! (at least by me
)
This little beauty is designed to conserve fuel for the precious "getting the hell off the Mun" stage by utilizing the power of monopropellant engines as the initial landing stage and leaving behind all that bulky science equipment after it gets used up.
The Hecate comes equipped with eight strategically placed Vernor Engines as a last resort against tippage (conceivably allowing it to get off the ground regardless of what angle it ends up at) as well as extensive life support systems to prevent loss of precious life.
Along with the previously listed features, the Hecate utilizes an asparagus style booster system equipped to survive re-entry for later use. This first generation craft is already the most advanced lander developed by BFEL industries and yet later models utilizing next generation technology are already planned that will allow the final spent booster to be utilized as an impactor probe.
The Hecate comes fully equipped as seen at the low, low price of 55000 kerbucks, order now to receive free shipping and handling as well as a complimentary Hecate action figure with kung-fu grip!
EDIT2: Yeah, nevermind all that. Need to totally redo the booster section and I'm pretty sure I need more monopropellant. I'll keep you guys posted
