The question is why space ships cannot use propellers or conventional airplane jets to move in space?
Stratosphere said:There is no air for them to use. Space is a vacuum.
ecao said:just imagine those tiny dust particles as micro meteors. Any propellar would be ripped to shreads. Also, there is no where near enough hydrogen or dust to use a propellar let alone a jet engine.
jsea-7 said:I presumed that. But I also thought that space contained cosmic dust and hydrogen and hellium atoms, therefore it can't be a total vacuum.
Space ships use thrusters or rockets to maneuver in space. These thrusters provide thrust in a specific direction, allowing the space ship to change its velocity and direction.
The maximum speed at which a space ship can travel is determined by its propulsion system and the laws of physics. Currently, the fastest space ship, NASA's Juno spacecraft, has reached speeds of up to 165,000 miles per hour.
Yes, space ships can change direction in space by using their thrusters to provide thrust in a different direction. However, due to the lack of air resistance in space, it takes a longer time for space ships to change direction compared to airplanes in Earth's atmosphere.
Space ships turn by using a combination of their thrusters and their reaction wheels. The thrusters provide the initial thrust to change the direction of the space ship, while the reaction wheels help maintain that direction.
Astronauts can control the maneuverability of a space ship through various control systems, such as joysticks, control panels, or computer systems. They also receive training on how to operate the thrusters and reaction wheels to control the direction and speed of the space ship.
