'Shenzhou IV' Functions Normally for 100 Days

Outer space experiments by China's Shenzhou IV craft will significantly benefit the nation's oceanic observation and meteorological forecasts, scientists said Tuesday night.

Outer space experiments by China's Shenzhou IV craft will significantly benefit the nation's oceanic observation and meteorological forecasts, scientists said Tuesday night.

The prediction was based on the latest information to emerge from the country's fourth unmaned space ship, and probably the last before China launches a manned craft later this year.

Scientists disclosed that the orbital module of Shenzhou IV has functioned normally for 100 days, following the re-entry vehicle's return to earth on January 5.

It is the first time, China has put a multiple-mode microwave remote sensor into space -- aboard Shenzhou IV's orbital module, said Gu Yidong, chief design engineer of China's space application system.

The sensor is sending an array of "valuable data'' on precipitation, wind speed and direction, as well as the colour and temperature of the ocean's surface, said Liu Junze, on the team of the Beijing Aerospace Command and Control Centre.

Liu's centre, which monitors the orbital module operation, is the nerve hub of China's space programme. It directed the launches and recovery of four unmanned space capsules between November 1999 and January 2003.

"The information gathered so far indicates China has made a breakthrough in key technologies in microwave remote sensoring,'' said Gu, adding: "We hope we can apply this expertise in oceanic and meteorological satellites.''

China had never attempted microwave remote sensoring in space prior to this launch, said Gu.

China will send two oceanic and meteorological satellites into space in 2005 in its run-up to building a sophisticated earth observation system, officials announced earlier.

It is not immediately clear if the technical know-how from the latest space experiments will be used on those two satellites.

Gu and Liu said they believed the experiments from the orbital module will ultimately facilitate China's efforts to develop oceans, monitor pollution, help mitigate natural disasters, and provide more accurate weather forecasts.

Tang Wenjun, another member of the Beijing Aerospace Command and Control Centre, said they had issued more than 1,000 tele-commands to steer the flight and operate the orbital module.

The module will remain in space for another several months, he said, but declined to be more specific.

The Shenzhou IV was sent into space on December 30 last year.

The craft, whose translated name is Divine Vessel, is widely seen as the final dress rehearsal before China joins the former Soviet Union and the United States as the only nations to send a human into orbit. (China Daily News)
