Beijing - As China's Shenzhou 7 spacecraft prepared for
return to Earth later Sunday, Chinese space officials said a fire
alarm that went off during its first spacewalk was false.
Wang Zhaoyao, spokesperson for the country's manned space
programme, said late Saturday that an alarm sounded because of sensor
error, the official Xinhua news agency reported.
'We were quite nervous when the astronaut in the re-entry module
reported the fire alarm,' he told reporters.
But he said officials 'became quite relaxed' when they realized
the fire alarm was in the orbital module which was 'opened to the
vacuum of outer space and no air was there to ignite the flame.'
Shenzhou 7 is the latest stage of China's plan to build an
integrated ground-space network for space exploration and manned
space research, including a permanent space laboratory by 2020.
It first sent an astronaut into space five years ago.
The spacewalk by China's 'taikonaut' Zhai Zhigang Saturday
afternoon lasted 20 minutes and was watched by Chinese leaders,
including President Hu Jintaoi, on live transmissions.
Chinese officialdom hailed the milestone as another reason for
national 'pride and joy,' along with the successful conclusion of the
2008 Olympic Games.
The three-man mission is to to return to Earth about 0940 GMT if
everything goes 'smooth' and 'according to preset schedules,' said
Deng Yibing, chief engineer of the astronaut training center.
He warned however that the return had some risks and it was
possible the taikonauts could be hurt if anything goes wrong.
'The spacecraft will reach the earth shortly before it grows dark,
making the search and rescue mission more difficult than previous
missions,' Deng said.
The mission began on Thursday with launch from the Jiuquan
Satellite Launch Center in northwest China.
During the mission, the astronauts launched as small monitoring
satellite less than 40 kilogrammes which was to orbit the orbital
module and send back the spaceship's first full video images.
