This is because space is a "vacuum" which means there is no air. Sounds waves need some kind of matter such as air, water, or solid and since there aren't any in space they can not travel therefore you don't here any sound
In space, there is no medium like air to carry sound waves, so there is no way for sound to travel from the spacecraft to an observer's ears. Therefore, a spacecraft moving through space would not generate any sound that we could hear.
it depends on the craft
Newton's second law of motion.
You had better travel near the speed of light or you will not see much of the universe. Unfortunately travelling near the speed is not yet possible, so you are out of luck.
newton's first law ---dealing with inertia
Newton's 1st Law
A spacecraft can travel forever in space because there is no air resistance or friction to slow it down. Once a spacecraft achieves a certain speed, it will continue to travel at that speed unless acted upon by another force, such as gravity or propulsion systems.
In space, there is no air resistance to slow down spacecraft traveling at constant velocity. Additionally, spacecraft can use thrusters or gravitational assists to adjust their speed if needed. The laws of physics allow spacecraft to maintain their speed in the vacuum of space.
You may have seen photos or videos of astronauts who appear to be floating through the air while in space. They aren't flying, nor are they really floating, they are falling. Any orbiting spacecraft (such as the space shuttle or international space station) is actually falling around the Earth in a circular pattern. They have achieved enough speed (over 17,000 mph) to continue moving around the Earth without the Earth's gravity pulling the spacecraft down. Astronauts aboard those spacecraft are moving inside the spacecraft and falling along with them at the same speed giving the appearance that they flying or floating inside.
it travels into space
Spacecraft are propelled through space using rocket engines, which work by expelling high-speed exhaust gases in one direction to generate thrust in the opposite direction according to Newton's third law of motion. Rocket engines can use either liquid or solid fuel to generate the necessary propulsive force.
A person will travel at the same speed as the spacecraft from which they have exited since they are no longer being propelled by any additional force. Their speed would be determined by the velocity of the spacecraft at the moment of exit.
