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. 宾语从句省略that to do做后置定语 that 引导定语从句 to do做后置定语修饰person doing做伴随状语 to do做目的状语 Earth’s gravity 地球引力 orbit v 绕轨道而行 ; n 轨道 step onto 踏上 giant leap 巨大的飞跃 agency n 机构 transmit data 传输数据 explore v.探索 ；exploration n.探测 ； explorer n.探险者，勘探者 succeed in doing sth. 成功做某事 realise/achieve one’s dream 实现某人的梦想 （one’s dream comes true） be
