There are few aspects of everyday life that aren't touched by the technologies developed for space travel.

You're on Earth. There's no cure for that.

MY thoughts can Travel as Far as Space..

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.
