The entire rocket launch process

Answer 1

A few days before the launch, the researchers began to assemble the rocket layer by layer. At the top was the astronauts 'cockpit. To ensure safety, there was a protective shell outside. After assembly, the rocket was slowly transported to the launch site. This process required extreme caution and took several hours.

After the rocket arrived at the launch pad, it had to undergo a comprehensive inspection. The launch pad support held the rocket, and the service tower was like a " bodyguard " to check again. From the power supply to the fuel injection system, everything had to be carefully checked. The service tower could touch every corner of the rocket to ensure that the parts were intact.

After everything was ready, the rocket's tiered propulsion system came into play. The propulsion system was divided into three parts. After the fuel of each part was exhausted, the thrusters automatically separated to reduce the load. The bottom was the engine and there was a straightening device beside it. During the launch countdown, the escape tower above the rocket was on standby. In the event of an accident, the cockpit could be taken off the rocket to ensure the safety of the astronauts. After that, fuel was injected. About seven hours later, the astronauts were sent to the top of the rocket through the internal elevator.

After entering the cockpit, the astronauts had to conduct equipment testing for about two hours, while the crew outside did a final inspection. Half an hour before the launch, the launch pad began to separate. Fifteen minutes later, all relevant personnel evacuated. At the last minute, the rocket device was retracted, and the engine at the bottom was ignited. The rocket slowly rose. A few dozen seconds later, the rocket adjusted its angle to the predetermined orbit. Two minutes later, the escape tower above the spacecraft separated. At this time, the thrust at the bottom of the rocket accelerated the spacecraft at a speed of nearly 8 kilometers per second.

About three minutes later, the rocket broke through the high temperature caused by the intense friction in the atmosphere. The heat shield separated, and then the bottom propulsion device separated. The rocket entered the space environment and entered a weightless state. The astronauts felt the floating experience, and the spacecraft unfolded the solar panels to provide power. Finally, the spacecraft chased after the space station at a speed of thousands of kilometers per hour along the orbit. It needed to accurately adjust its position and speed to achieve docking with the space station.
