Question: Is a passport needed to travel into space? if not could you use it to get in and out of countries without it?

Nice approach! No, a passport is not needed, because there are so few astronauts yet that the people who send them up already know exactly who they are! Thus, they do not need to produce documents in order to board their spaceship! Sometimes astronauts take off from one country (e.g. the USA) and return to Earth by landing on another country (e.g. Russia). Since these countries are always collaborating, this is normal. In the future, if space travel becomes as ordinary as catching the plane, there will probably arise a need for passports, especially if you take off from one country and land in another one!
