【热点材料】担负中国首次地外天体软着陆和巡视探测任务的嫦娥三号,2013年12月2日1时30分在西昌卫星发射中心发射升空,展开奔月之旅。由着陆器和“玉兔”号月球车组成的嫦娥三号月球探测器,总重近3.8吨。在月球表面软着陆后,“玉兔”号将驶离着陆器进行为期约3个月的科学探测,着陆器则在着陆地点进行就位探测。为满足嫦娥三号入轨精度要求,中国目前推力最大的长征三号乙运载火箭进行了多项技术状态改进,提高了可靠性和安全性。这也是长征系列运载火箭的第186次飞行。
【Hot Materials】 Chang’e III, responsible for the soft landing and patrolling mission of China’s first extrasolar astronaut, was launched at Xichang Satellite Launch Center at 1:30 p.m. on December 2, 2013 and was on its way to the moon. The lantern Chang’e III, consisting of a lander and a “Yu Rabbit” lunar rover, weighs nearly 3.8 tons. After a soft landing on the surface of the moon, the “Yu Rabbit” will depart from the lander for a scientific survey of about 3 months, while the lander will conduct a spot detection at the landing site. In order to meet the requirements of orbit precision of Chang’e III, a number of B-rocket launchers with the largest lift force in China have carried out a number of technical status improvements and improved their reliability and safety. This is also the 186th flight of the Long March series carrier rocket.
