The Science of Space Travel: How Rockets Work

Описание: The Science of Space Travel: How Rockets Work

Rockets are a crucial component of space exploration, serving as the primary means of propelling spacecraft beyond Earth's atmosphere and into space. Rockets work by using a combination of fuel and oxidizer to generate a powerful burst of energy, known as thrust, which pushes the spacecraft forward and overcomes the force of Earth's gravity.

The amount of thrust needed to escape Earth's gravity depends on a number of factors, including the weight of the spacecraft, the distance it needs to travel, and the speed it needs to achieve. To achieve escape velocity, which is the speed needed to break free of Earth's gravitational pull, rockets must be able to generate an enormous amount of thrust. This is typically done by using multiple rocket stages, which are sequentially discarded as their fuel is depleted, allowing the spacecraft to shed weight and achieve higher speeds.
