The most efficient launch trajectory is due east from a launch site, which places the satellite into an orbital inclination equal to the latitude of the launch site.
最有效的发射轨道应该在发射地点的东边，使卫星轨道倾度与发射点纬度相等。
This has been an important motive behind China 's recent push to become a space power, with the launch of two manned orbital craft in 2003 and 2005.
中国在2003年和2005年成功发射两艘载人飞船后迅速成为宇航强国是其重振的源动力。
There are a few elements of the BX-1 launch and operations that do not correlate to what would be expected from a co-orbital ASAT test.
BX - 1的发射和运行和共轨反卫星测试不相关的证据也有好几个。
We propose performing launches of spacecraft of other nations and international organizations with our launch vehicles and carrying out joint studies at orbital stations, based on mutual agreement.
我们希望在双方协商的基础上，用我们的运载火箭实现为其他国家或国际组织发射航天器，并在轨道空间站上开展联合研究。
Because of the complicated launch and on-orbital working condition, and working with multiband, AF technology is a key technology for large space telescopes.
对于大型的空间望远镜，由于发射和在轨工作环境复杂，且常要求在多波段下工作，从而使得在轨自动调焦成为必不可少的一项关键技术。
But merely halving the cost of launch could stoke increased demand for launch services and bring a flood of new entrants into the orbital domain.
但仅仅让发射成本减半，就会带动发射服务的需求大幅增长，从而使太空轨道迎来大批新成员。
Fengyun's loss also could be due to a massive meteoroid or orbital debris hit, occurring coincidentally within range of China's main space launch base. But the odds of that are even smaller.
还有可能风云卫星是在中国基地发射导弹的同时被小行星或太空垃圾击中，但这种概率更小。
Also in June, it was announced that the contractor Orbital ATK would be responsible for Orion's Launch Abort Motor.
此外，在六月，它宣布，承包商轨道atk将对猎户座发射中止马达负责。
If that's the case, why did NASA launch MESSENGER in 2004, and why do we eagerly await its orbital insertion in 2011?
