If I'd thought about it more I would've put two food canisters on my probe just to leave some out there for future stupid mistakes, but I just sent up one in a KAS box and had the engineer grab it and bolt it to my ship. Maybe I'll take advantage of some satellite contracts to leave some emergency snacks here and there, just in case...

I installed RoverDude's life support mod and immediately sent up a mission to Minmus with no food for the crew, which I didn't notice until they were halfway there. Fortunately, they didn't have to turn around and come right back home or dramatically shorten their mission, so it doesn't really count as "ruined". I launched a food probe that caught up to them in Minmus orbit in time to prevent any problems.

I've seen this pop up off and on since career mode was added so I finally signed up to comment on it. If you look at the US space programs, manned missions came well before anything other than primitive tests. The first unmanned satellites didn't do much. They transmitted, but weren't controllable. Some had instruments to give them something meaningful to send back, but in terms of KSP that kind of mission wouldn't give you much to do except launch and maybe do some staging. At best it would be a single launch to get you a science point or two to start the manned program. The Mercury program did several unmanned test flights prior to Al Sheppard going but they were all sub-orbital and, again, very little was controlled from the ground. So KSP is basically starting you with the first manned Mercury mission, at which point probes that did anything useful were still a few years away.
