| chinanews, jiuquan, sept. 9 – china's first satellite shijian-8 specially designed for seed breeding in space blasted off successfully at 3:00 pm september 9 at jiuquan satellite launch centre in northwest china's gansu province.
the satellite carries more than 2,000 varieties of plant seeds in nine categories, including grains, cash crops and 2 plants, as well as seeds of 3 and 4 biomaterials.
the "seed satellite" will enable scientists to try and cultivate high-yield and high-quality plant varieties.
since 1987, nine chinese satellites and several of china's six shenzhou spacecraft have carried seeds for experiments and a number of new species of plant seeds have been bred in space, but never before has the country launched a satellite exclusively for seed breeding.
