Answer:
Preparing for a space mission takes a lot of planning and training. This is also similar to the preparations done by someone going on a camping trip.
Individuals are taught the basic survival tools out there. The conditions may be a little harsh and strange or filled with lots of uncertainties out there which is the main reason for adequate preparation.
The preparations are different due to the location of both activities. Camping has gravitational force to contend with while in space missions there are little or no gravitational force to contend with.
