Although the exact date of when rockets were first invented is still unclear‚ it is believed that the Chinese invented the first “rocket” (“The History of Rocket Science”). Moreover‚ the Chinese used gunpowder‚ invented in around 100 A.D‚ and positioned it in Bamboo sticks for religious festival tradition (“The History of Rocket Science”). Large bamboo sticks were created and decorated by Monks and villagers‚ then blasted skyward to inform the Rain God Phaya Thaen that it is time to send rain down

Sputnik 1‚ which was the world’s first artificial satellite to reach space. The launch of Sputnik 1 on October 4th‚ 1957 was the first big step in the space race and demonstrated the USSR’s advanced technical abilities. " Sputnik 1 was about the size of a basketball‚ weighed 183 pounds and orbited the earth in only 98 minutes"(Siddiqi). Two months after the launch of Sputnik 1‚ the United States tried to match the Soviet Union by launching their own satellite‚ but their attempt failed. "Oh What a Flopnik

orbital launch was of the Soviet unmanned Sputnik ("Satellite I") mission on October 4‚ 1957. The satellite weighed about 83 kg (184 pounds)‚ and is believed to have orbited Earth at a height of about 250 km (150 miles). Analysis of the radio signals was used to gather information about the electron density of the ionosphere‚ while temperature and pressure data was encoded in the duration of radio beeps. The results indicated that the satellite was not punctured by a meteoroid. Sputnik 1 was launched
