Rockets launch by using a combination of fuel and oxidizer, typically liquid or solid propellants, to create thrust and propel the rocket upwards. The rocket's engines ignite and push the rocket forward, overcoming the force of gravity.
Rocket launches serve various purposes, such as launching satellites into orbit, exploring outer space, and testing new technologies. They also play a crucial role in delivering supplies and equipment to astronauts on the International Space Station.
The trajectory of a rocket launch is determined by various factors, including the rocket's speed, direction of thrust, and the Earth's gravitational pull. Scientists use mathematical calculations and computer simulations to determine the ideal trajectory for a successful launch.
The time it takes for a rocket to reach space varies depending on the type of rocket and its destination. On average, it takes about 8 minutes for a rocket to reach low Earth orbit and 3 days for a rocket to reach the Moon.
Before a rocket launch, extensive safety measures are taken to ensure the safety of both the crew and the general public. This includes thorough testing of all components, emergency procedures in case of malfunctions, and a designated launch exclusion zone to keep people and property out of harm's way.
