Helicopter carries the return capsule off the ground in Suining, Southwest Sichuan Province on September 24, 2006.
China's seed-breeding satellite, Shijian-8, successfully landed in Sichuan Province at 10:43 am Beijing time yesterday after a 15-day flight in space.
The recoverable satellite was launched from the Jiuquan Satellite Launch Centre in Northwest China on September 9. The satellite's return capsule was recovered in Suining, Sichuan Province. The orbital module will continue to orbit the earth and carry out more experiments until its battery runs out.
The satellite carried 215 kilograms of seeds of vegetables, fruits, grains and cotton, the largest load of this kind since 1987.
Scientists from the Space-breeding Centre of the Chinese Academy of Agricultural Science used the mission to carry out experiments aimed at discovering what happens to the germination and sprouting of plants when they are exposed to zero gravity.
After being exposed to cosmic radiation and zero gravity, some seeds may mutate and produce higher yields and improved quality when planted back on earth, scientists said.
During its flight, the satellite sent back high-definition digital images of sprouting vegetables, according to the Institute of Plant Physiology & Ecology with the Shanghai Institute for Biological Sciences under the Chinese Academy of Sciences.
An official from the Ministry of Agriculture said the ministry will ask research institutes to use the seeds returned from space to develop new strands featuring high yields, good quality and high efficiency.
Since 1987, China has carried out seed breeding tests on nine satellites.
The Shijian-8 is the 90th space flight made by Long March rockets and the 23rd time China has launched a recoverable satellite. China has chalked up 48 successful space launches in a row since October 1996.
