When a rocket launches, the scene is truly breathtaking! With a earth-shaking 'rumble' sound, the bottom of the rocket blasts out massive, bright-red flames and billowing white smoke. This tremendous thrust pushes the heavy rocket faster and faster, bravely overcoming Mother Earth's gravity to soar straight up into the blue sky! During the first few seconds of leaving the ground, the rocket burns the most fuel because lifting such a heavy metal giant is no easy task. Usually, a rocket's body is divided into several sections, acting just like a relay race—once the first stage runs out of fuel, it detaches and drops away to shed weight, letting the top section fly even higher. China's 'Long March rocket series' has successfully carried tons of satellites and astronauts into mysterious space!
