These disasters made everyone sad and disappointed, but the desire to explore the universe never died. This is because people believe in the importance of carrying on space exploration despite the huge risks. An example of this ongoing work is the International Space Station. It orbits Earth and has astronauts from different countries on board, providing a continuous human presence in space.
A. Although scientists try to make sure nothing goes wrong, accidents can still happen.
⑤___________________________________________ Europe, the US, and China all have plans to further study and explore planets like Mars and Jupiter.

② 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 experiences, they succeeded in making rockets that could excape 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 achived. For example, America’s NASA space agency launched Voyager 1 on 5 September 1977 to study deep space, and it still transmits data today.
