30 days? This dude will suffer some major psychological damage once he reemerges, and from the looks of it, some physical problems too. As for comparing this to anything related to a NASA mission - let's not forget that NASA keeps its astronauts physically and mentally active so it's hardly appropriate to compare that to a silly man laying in a metal coffin for 30 days.
Hmm, they helped narrowing down finding him, we have his name, and the fact he's somewhere familiar. Which means he's ether somewhere he knows or likes going to or somewhere near friends or family, also, given the weather here recently he has to be indoors otherwise the metal box would make him freeze to death. Does Tim Shaw have a facebook page?
what you don't see behind the camera pointed at the back of his head is the big opening that he goes through that leads into the house where he takes a dump and a shower, has good meals, watches some hulu and checks his farmville before heading back inside to put on the next act.
