Architects: Last report. I suppose I should have done this a while ago.  I'm not sure how long I've been sitting on this asteroid, but I can tell you how I got here.Brad and I were retrieving another comet from just inside Jupiter's orbit.  We'd just sent it on the correct trajectory to land on Mars six years down the line when our shuttle was hit by something, sending vibrations through our seats.  Alarms screamed from the control panel that we were leaking atmosphere from two areas of the shuttle’s skin.  Brad was calm, as though he’d been through the situation a hundred times before, but I knew it was only the third time it had happened to him.  It was something that every pilot went through at least once in his career, just a part of space travel.  The thing was probably no bigger than a grain of sand, but it punched straight through the aluminum walls, giving us two puncture holes to fix.  One was easy to find, high on the port side of the sleeping quarters, but the other was behind an instrument panel which had to be dismantled before we could stop all the precious air from escaping into the vacuum.  Brad had got into his space suit in record time before we had fixed the first hole.  By the time the second hole had been plugged we'd lost about 70 percent of the atmosphere.  Brad said we had been lucky to survive such an impact, which turned out to be his last words.Whatever it was that had hit us also punched a hole through a fuel line in the rear section, behind the sleeping quarters.  I'm guessing, but I'd say we must have vented a bit of fuel and when the shuttle did its automatic station keeping thrust from one of the attitude rockets down the flanks of the wings the fuel ignited.I don't know what that stuff is made from - chemistry was not one of my strongest subjects - but when the fuel was lit it blew the whole side on the ship away, wing and all.  What little air we had left inside blew us both out and into space.  We landed, quite by chance, on an asteroid that we'd just flown past which is where I'm making this report.I, obviously, survived the impact but sustained two broken legs and a broken arm.  My right arm isn't strong enough to propel me around, so I've been sat here since we landed.  Brad wasn't so lucky (is that the right word?) as he landed head first.  His helmet smashed and he died almost instantly of suffocation.  I activated the emergency beacon as soon as this all happened, but these units don't have much power to the signal, so I'm not sure anyone will hear my SOS.That amused me when I was in training.  Someone told me that SOS stood for 'Save Our Souls' - something that has little meaning for me.  Never really read anything about religion or the afterlife.  Who knows if the soul really exists?I did manage to get in touch with the computer on the shuttle but she wasn't much help.  Turns out the main radio was also damaged by the fuel explosion so she couldn't radio for help.  She's now orbiting the asteroid at about a fifty mile radius.  Can't get any further in with the thrusters she has working.  If my legs worked I could have jumped - there's very little gravity on this little rock.  At a guess I'd say it was only about two miles in diameter.  The comet Brad and I pushed towards Mars was about a mile and a half wide, so this isn't much bigger.I can hear a beeping now.  Must be the main battery about to die, which will ultimately mean the end of me.  Funny thing though - they guarantee those things for a hundred years.  It can't have been that long since the crash, can it?  Guess I'll never know now.  Maybe if Brad had survived the crash we might have been rescued by now.  If they were scanning for life signs in the right area they would have found us and we'd be back in space and Brad wouldn't be staring at me with his dead eyes and a look or horror on his face.  At least I think its horror. I was never any good with reading emotions. Maybe we'd get taking back to Earth - always wanted to go there.  I asked a few people what it was like and whether I'd have a chance to visit it, but I never got a straight answer.  Can't blame them though - we machines aren't supposed to have dreams like that.I think the shuttle will be passing over head soon.  I've had an idea, but I'm not sure if it is possible.  Is it possible to cheat death?  I'll know soon enough.The beeping is getting faint now, which means I probably only have seconds to live, so this is mining droid MW6942F of the shuttle Midnight Dwarf signing offffffffffffffffff.
