A zero-gravity flight is a first step toward space travel.

The first step toward change is awareness. The second step is acceptance.

how much does it cost now for a mock space travel in the planetarium? That will b the future cost of space travel, Isnt it?

future space travel = Your bus and taxi fare here is how u get the same idea that i have. goto any nearest planetarium and see the show. at the end of it just say 2 questions. how was the space travel? HOw is the space ship?

It is looking more and more likely that this could be a problem for long-term space travel.

There is a place in Virginia looking at space travel. Some of the financial backers own large travel agencies. There is big interest in this in the corporate world.
