I'm not sure specifically what the 'rocket sad story' is without more context. It could be about a rocket launch that failed, perhaps with the loss of a valuable payload or the end of an important space mission.
Meowth in Team Rocket has a sad story mainly because of his unrequited love for a female Meowth. He learned to speak human language in the hope of impressing her, but she still rejected him. This made him feel very sad and lonely, yet he continues his journey with Team Rocket.
Rocket Raccoon has a sad story. He was created through cruel experiments. He was taken from his home and turned into a weapon or tool by those unethical scientists. He was alone in a world that saw him as a freak. His only friends were those he found along his adventures like the Guardians of the Galaxy, but the memories of his past torment still haunt him.
Yes, 'Rocket Boys' is based on a true story. It tells the real - life experiences of a group of boys in a small mining town who were interested in rocketry.
Once upon a time, there was a shiny rocket. It stood tall on the launch pad, waiting for its big moment. The rocket was painted bright red with silver stripes. The countdown began, 10, 9, 8... and with a huge blast, it soared into the sky. Inside the rocket were brave astronauts. They were on a mission to explore a new planet. As the rocket left the Earth's atmosphere, the view outside the window was amazing. Stars twinkled all around. The rocket carried them further and further into the unknown.
There was a rocket made especially for kids' dreams. This rocket was small but very powerful. It had a big white star painted on its side. A group of kids were allowed to visit the rocket before its launch. They left their handprints on it as a good - luck charm. When the rocket launched, it flew so fast that it left a colorful trail in the sky. It carried a small satellite that would send back pictures of the stars for the kids to see. It was a very exciting day for all the children involved.
