...To be sure, given the existence of transporters, these off-ship forays could seldom be considered "missions" as such. They were more like the heroes stepping off their space-traveling house to catch some fresh air on the patio, or perhaps receive some guests there, or have a look at the flower bench and the butterflies there. It just so happened that their patio was a different planet on different days! Barring disasters, they were never more than one step away from their very own water tap, kitchen, bed or water closet. It just happened to be a step hundreds of kilometers long...
Now, in theory, they should have prepared for the eventuality of being stranded, being incapable of taking that single step back to the house. But would we really do that, if the step was so easy to take, if the odds of the house suddenly being somewhere else out of reach were so low?
Certain off-ship missions did begin with our heroes fully well knowing that they might not be able to reach their ship again any time soon. For those, the objection is valid. But for most of the missions, we could be talking about a significant cultural difference where our intuition fails us.
If we fly to a friend half a continent away, we don't pack a tent in case we get stranded somewhere halfway, no matter how much the caveman in us might be objected to the idea of seeming cross-continental travel without such security measures... If we phone that friend, it wouldn't occur to us to even wear shoes for the "trip", let alone pack that tent! Going to places via transporter might be as different from conventional travel as using a telephone is.
