“实践八号”育种卫星9月24日成功归来
[ 2006-09-25 15:44 ]

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.

在经过15天的太空飞行后,我国"实践八号"育种卫星于北京时间9月24日10时43分在四川省境内成功着陆。

"实践八号"可回收育种卫星9月9日在我国西北部的九泉卫星发射中心发射升空。

"实践八号"卫星返回舱在四川省遂宁县落地回收。卫星留轨舱在电池耗尽之前,还将在轨运行一段时间,继续进行一些科学实验任务。

"实践八号"卫星共搭载了215公斤蔬菜、水果、谷物和棉花种子上天,是1987年以来搭载种子量最多的一次。

中国农业科学院太空育种中心的科学家们希望通过"实践八号"所做的科学实验探测失重对种子发芽产生的影响。

科学家介绍,在宇宙辐射和失重环境下,有些种子可能会发生变异,这些变异种种植到地球上后,能培育出高产优质的新品种。

据中科院上海生命科学植物生理生态研究所介绍,"实践八号"在飞行过程中传回了一系列高清晰的青菜太空发芽的照片。

农业部的一位官员说,农业部将要求有关研究机构把从太空回来的种子培育成高产、优质、高效的新品种作物。

从1987年起,中国相继进行了九次太空育种实验。

"实践8号"育种卫星是中国发射的第23颗可回收卫星,这次发射也是长征系列运载火箭的第90次飞行。自1996年10月以来,我国已连续第48次取得太空发射成功。
