Hmmmm....while i've never had to use it, nor even had one fitted, can no one see how getting killed, because you can't repair something, 50kly out from civilization, with the time involved getting that distance and scanning, is a penalty so disproportionate to the effort put into the activity that it makes this far too punishing?, not one single other activity in the game is punished in this manner, not because of the money lost, but simply because of the sheer amount of time lost, especially if you're a casual player, making such a trip can take whole weeks!. If you could keep the exploration data after death then it would make it better (but it would still be too much of a punishment) but as far as i can see, this risk makes exploration far too dangerous, even if it's something not likely to happen with any high degree of probability but when it does happen it's enough of a punishment to simply crush any desire to embark on such a journey ever again and that's not good game design IMHO.
We really should have the option to mine the required materials to repair the rest of the ship, including power plant, it would be an extra module apart from the AFMU and would require mining lasers and refinery (of course) as well as cargo space so fitting becomes a very finely tuned affair but overall the risk of death to exploration should be diminished since pilot error isn't the only danger, after all, you cannot know, prior to entering a system, if you are going to appear between a contact binary which immediately begins to cook up your ship.
Edit: But if nothing is going to be done to diminish this risk then at least make it much more profitable than it is now, i believe exploration is the least profitable career at the moment since the money earned for a 3,000ly trip which takes days can be done in less than an hour of trading, or a couple of hours bounty hunting and taking into account the time involved well, that's just not fair, the risk involved should make this at least as profitable as trading, after all, we're finding whole planets that will make the superpowers of the galaxy and their corporations trillions of cr.
