One afternoon in the summer of 1989, a 27-year-old food technologist, called Helen Sharman happened to be listening to the radio.She heard an unusual position being advertised: "Astronaut wanted—no 【C1】 pre________experience necessary".She wrote down the phone number and the next day sent off her application.
Sharman was one of 13,000 hopefuls who applied to become the first British astronaut when the British agreed to co-operate with the Russians on the Juno space mission.Applicants for the project had to take tough psychological and physical tests.They needed to be scientifically trained, had to speak a foreign language and had to be able to deal with difficult situations, without panicking.Helen Sharman turned out to be【C2】 id________.She was a highly-trained scientist, could speak several languages and was well known for her ability to stay cool under pressure.Obviously, physical fitness was also important, and, although Sharman often played squash and regularly went cycling and swimming, she now admits that she was no great athlete when she applied.A strong digestive system was also vital.In space there’s almost no gravity, so the movement of food through the stomach is dependent on muscle power.
To Sharman’s surprise, her application was successful, and six months later she was in Russia, 【C3】________(begin) eighteen months of training.One of the most interesting parts of her preparation was a set of tests which simulated weightlessness."Actually, it’s extremely difficult to do this on Earth," explains Sharman, "because to weigh absolutely nothing you have to be positioned between two planets so that the force of their gravity is pulling you in opposite【C4】 ________ (direct)." The nearest it is possible to get to these conditions on Earth is in a plane that is flying in enormous loops."We used huge aircraft.When the plane gets to the top and starts to fall, you fall with it, so you feel as if you’ re weightless.Each experiment only lasted about 23 【C5】________ —not very long—otherwise it would hit the ground." Once in space, Sharman got used to weightlessness, despite a little initial discomfort.
Another important part of Sharman’s preparation included learning about the technical aspects of space travel.There were only three people in the spacecraft, and they all needed to be able to operate it.The Russians wanted to make 【C6】________Helen could operate all the systems she would need to survive on her own in an emergency.
On 18 May, 1991, Sharman boarded the Soyuz spacecraft with two Russian cosmonauts.Once it was in space, the craft travelled【C7】________a speed of 29,000 km/h.It docked with the Mir Space Station two days later.She says living up there was not as【C8】________(frighten) as it sounds."Eating wasn’t too difficult.We sucked coffee and tea
out of tubes and ate tinned food."
In space Sharman carried out experiments on various materials to be used for new drugs and electronics.The results were brought back to Earth for 【C9】ana_________.
Although she would like to go back into space, these days Sharman is happy working as a part-time consultant to a company making satellites.The rest of her time she spends trying to persuade schoolchildren to take up a【C10】car____________ in science and technology.
【C7】
