With every inch of land on Earth now catalogued by our satellites, the stars are the next place we as a species must travel. And with a booming world population that will hit 9.1 billion in 2050, large-scale space travel may become a necessity.

Point-to-point transit via low orbit could dramatically speed up international flights, connecting the world even further. And safe, consistent space travel opens up the possibility of commercial space stations, trips to the moon and exploration beyond.

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?

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.
