Tourists will have to be not only physically fit but also mentally and emotionally ready as well, to help them become comfortably and at ease while on the trip. One current space tourism package specifies for the space travel to last for up to 10 days, unless the trip includes spacewalks, then approximately 8 days would be added to the venue.
You are probably wondering why only a few people have traveled as tourists to the International Space Station. There are practically two reasons that include a limited number of space transports and high costs.
Since the cost of spacewalks and/or space travel is currently prohibitive to the masses, many enterprising businesses have constructed facilities that will simulate the actual conditions of outer space. Once inside these facilities,an individual will feel what its like be in orbit, though without the privilege of spacewalks.
In the next 10 to 12 years, when costs come down, even the middle class most likely will be able to scrounge up the money for a short trip to low earth orbit, experience weightlessness and take a couple of short spacewalks before coming back to Earth. And who knows, a few short years after this you may even be able to walk your dog in space. Won't this be heavenly?
