vacuum
A hot air balloon requires air to generate lift. In outer space, there is no air or atmosphere, so there is nothing for the hot air balloon to displace to generate lift, causing it to be unable to float.
I assume here that by "air composition" you mean the material between planets and stars. Typically space is nothing; or rather almost nothing. You can think of it as a very big room where all the air has been sucked out and the preassure is zero or very close to zero. That being said there is actually material floating around out there: planets, asteroids, stars and even big clouds of different types of gas. So to answer your question, you can't really talk about "air composition" in space, because mostly there is nothing at all.
In space, you can touch the surfaces of your spacecraft or space station, as well as any tools or equipment you have with you. However, you can't touch anything outside of your spacecraft or space station, as there is no air in space to transfer the sensation of touch.
The space shuttle's main engines are used to propel it into orbit and make course corrections in space. Once in orbit, thrusters are used to adjust its position and orientation. Additionally, the shuttle can rely on gravity assists and other celestial phenomena to maneuver in space.
Sound requires a medium such as air to travel through. There is no air on the moon or in the space between Earth and the moon, and thus nothing to carry the sound.
A vacuum is a space in which all air has been sucked out.
vacuum or void
no. Actually air exist on the surface of planets. It sticks to them because of gravitational force. there are no air particles in space. space is just nothing.
Scientists call air, air. There is nothing unscientific about the term air.

The Air and Space museum has nothing from the colonies. It deals with space exploration and has space suits and moon rocks.
Due to the vacuum of space, nothing. The air would be dispersed and have no effect on anything in space
Yourself in outer space. Your reflection. Your shadow.
Like nothing because there is no air in space to carry the scent
I believe that would be called return air.
When a station is off it is called OFF-AIR. When the station is on but nothing is playing, it's called DEAD-AIR.
A vacuum is empty space with no air. It is a region where the pressure is significantly lower than atmospheric pressure, resulting in the absence of air or any other gas molecules.
