Space vehicles can be many miles in length, or only 3000 feet. A Example of a Large space vehicle is the USS Voyager. A small space vehicle would be something like the Apollo that went to the moon.
Of all the space around your vehicle, it is the area ahead of the vehicle - the space you are driving into - that is most important.
Vehicle operating space is the area around the vehicle that cannot be seen from the driver's seat.
Scientists do research, do test and go into a space vehicle to do experiments. They also go out the space vehicle in space suits.
While they flew, the space shuttles were the only reusable space vehicle. Even they no longer fly.
The space shuttle is reusable.
