A point where you no longer have enough fuel, air, or other resources to make it back safetly.
Sound waves require a medium to travel through to propagate from point A to point B. In space there is no such medium, so sound does not travel in space.
We travel by a space rocket!
Well for starters we are actually able to get into space with a space shuttle...
it has changed the space travel as it was a reusable which saved money of the particular space agency
Cosmonauts typically travel to the International Space Station but in general travel to outer space.
Columbia was a Space Shuttle. Space Shuttles travel to an orbit around the Earth and return.

From travelers - if you travel so far that your supplies will run out before you could return to your origin, that's the point of no return - you have to keep going forward at that point because you know you'd never make it back.
Probably safe to say mid-point. When it's as far to go back to your start point as to go on to your end point. I would point out that the "no return" part does not imply the mid-point. It is the point when it is no longer possible to return to your starting point safely. If I am flying 150 miles away and have enough fuel to travel 200 miles (and some reserve for safety) then the point of no return is 100 miles out, not 75 miles. It is the point when I can no longer return to my starting point safely and must continue on to the end point.

No

It means that it is too late to change your mind about doing something. So if you were in an aircraft with enough fuel to travel one hundred miles, then the point of no return would be at mile 50 because after that point, you would not have enough fuel to make it back to your starting point.
space travel denefits me =)
no, it could take more time to return to USA, but you can come back with out a passport
If you followed a straight line around the equator you would travel 40,075 Km (24,902 miles) to return to your starting point.
Space travel is done by means of rockets.
