And although I had been writing and speaking about space travel for years , the moment is still frozen in my own memory : I was in barcelona attending the eighth international astronautical congress .
The research was presented at the american astronautical society meeting in cape canaveral , fla. , last week . It also appears in the journal of bone and mineral research .
This exhibit creates an environment simulating how astronauts walk on the moon , letting visitors experience the feeling of walking under conditions of weightlessness or little weight , and allowing audience members , especially young people and teenagers , to acquire an interest in astronautical activities .
