中國首顆微重力實驗衛星"實踐十號"發射

China successfully launched its first Microgravity satellite, the SJ-10, at the Jiuquan Satellite Launch Center in Gansu province Wednesday at 1:38 am.

週三凌晨1時38分，我國首顆微重力科學實驗衛星實踐十號在甘肅酒泉衛星發射中心成功發射。

Designed in the shape of a bullet, the SJ-10 carries 19 experimental loads for 28 scientific research projects in microgravity, involving microgravity fluid physics, microgravity combustion, space material, space radiation effect, microgravity biological effect and space bio-technology.

子彈形狀的實踐十號將進行涉及28項微重力科學研究項目的19項實驗，涉及微重力流體物理、微重力燃燒、空間材料科學、空間輻射效應、微重力生物效應、空間生物技術等。

Microgravity experiments have previously been carried out on space facilities, including space stations, space shuttles and research rockets.

微重力實驗此前已經在包括太空站、航天飛機和探測火箭等太空設施中進行了。

The SJ-10 will stay in the orbit for a few days and an orbital module will stay in orbit another few days for additional experiments.

實踐十號將留在會在軌道上停留幾天，而軌道艙將在軌道上再多停留幾天以進行額外的實驗。

The SJ-10 is the second of four scientific satellites under a CAS space program. Unlike the other three, the SJ-10 is returnable. It is the 25th such retrievable satellite launched by China.

實踐十號是中科院空間項目4顆科學衛星中的第2顆。與另3顆衛星不同的是，該衛星屬於返回式衛星。實踐十號是我國發射的第25顆返回式衛星。

"The recoverable satellite is a useful and efficient tool for microgravity experiments, compared to space stations and research rockets," said physicist Hu Wenrui, chief scientist of SJ-10 and a member of the Chinese Academy of Sciences.

我國著名物理學家、同時也是實踐十號的首席科學家、中國科學院成員胡文瑞說道：“相比空間站和探測火箭，返回式衛星在微重力實驗中是一個更有用的和有效的工具。”
