Before the mid-20th century, most people felt travelling into space was an impossible dream. However, some scientists were determined to help humans realise their dream to explore space. After many experiments, they succeeded in making rockets that could escape Earth’s gravity. On 4 October 1957, the Sputnik 1 satellite was launched by the USSR and successfully orbited around Earth. Afterwards, the USSR focused on sending people into space, and on 12 April 1961, Yuri Gagarin became the first person in the world to go into space. Over eight years later, on 20 July 1969, American astronaut Neil Armstrong stepped onto the moon, famously saying, “That’s one small step for [a] man, one giant leap for mankind.” Following this, many more goals were achieved. For example, America’s NASA space agency launched Voyager 1 on 5 September 1977 to study deep space, and it still transmits data today.
