a. fuel price rise, b. expenditure rise, c. needs are rising, d. technology advancement is growing, e. more easy access facilities for space visits, (like vergin galactic..etc.)
can a common man think to visit the space at once in his whole life span.!!, will it be feasible to lift-off a common man in space. ? can we show him his earth from there.?
