The Progress failure is a reminder that anything that has to do with technology is hazardous and if you do not deal with it by appropriate methods or get sloppy then failure will occur.  I know that its a big deal to say "space is hard" and that excuses all sorts of things including mediocrity or failure to follow established technical procedures and guidelines.  

I've been reading (because I am interested in it) some of the "lessons learned" documents on the early Ranger probes...Ranger was the first three axis stable platform and was a very very sophisticated vehicle.  The early probes (3-5) failed in no small measure because in that era they had no idea how a particular form of diode platting worked in the conditions of spaceflight.  Today well we are technically more mature.

Space is no "harder" then operating submarines in ocean depths were one leak the size of a hair stand is fatal in a very short period of time.  And we let 20 somethings run most of the systems there.  Including the nuclear reactor.
