“Are we alne? What’s ut there?” Lking up at the stars, peple have always wanted t learn mre abut space, and scientists wrk hard t find answers. They make vehicles t carry brave peple int space t find ut the secrets f the universe. They als really wish t discver ther planets that are suitable enugh t supprt life._____________
Main idea:
Peple are always curius abut space and scientists wrk hard t find answers.
Befre the mid-20th century, mst peple felt travelling int space was an impssible dream. Hwever, sme scientists were determined t help humans realise their dream t explre space. ___________ On 4 Octber 1957, the Sputnik 1 satellite was lunched by the USSR and successfully rbited arund Earth. Afterwards, the USSR fcused n sending peple int space, and n 12 April 1961, Yuri Gagarin became the first persn in the wrld t g int space. Over eight years later, n 20 July 1969, American astrnaut Neil Armstrng stepped nt the mn, famusly saying, “That’s ne small step fr [a] man, ne giant leap fr mankind.” Fllwing this, many mre gals were achieved. Fr example, America’s NASA space agency launched Vyager 1 n 5 September 1977 t study deep space, and it still transmits data tday.
Peple’s dream f space explratin came true in the 20th century.
Althugh scientists try t make sure nthing ges wrng, accidents can still happen. All the astrnauts n the USSR’s Syuz 11 and America’s Challenger died during their missins. These disasters made everyne sad and disappinted , but the desire t explre the universe never died. This is because peple believe in the imprtance f carrying n space explratin despite the huge risks. An example f this nging wrk is the Internatinal Space Statin. It rbits Earth and has astrnauts frm different cuntries n bard, prviding a cntinuus human presence in space.
Despite the huge risks, humans still desire t explre space.
China’s space prgramme started later than thse f Russia and the US, but it has made great prgress in a shrt time. China became the third cuntry in the wrld t independently send humans int space in 2003, when Yang Liwei successfully rbited Earth in the Shenzhu 5 spacecraft. Then Shenzhu 6 and 7 cmpleted a secnd manned rbit and the first Chinese spacewalk, fllwed by the vehicle Jade Rabbit being sent t the mn t study its surface. After that, China launched the Tiangng 2 space lab int space and Tianzhu1 t dck with it. This signalled ne step further in China’s plan t establish a space statin in the future. Mre recently, China has sent Chang’e 4 t explre the surface f the far side f the mn t make measurements and bservatins.
The future f space explratin remains bright. Eurpe, the US, and China all have plans t further study and explre planets like Mars and Jupiter. Despite the difficulties, scientists hpe future discveries will nt nly enable us t understand hw the universe began, but als help us survive well int the future.
