2016年11月3日晚,“5、4、3、2、1,点火!”伴随着指挥员喊出的起飞、助推分离、整流罩分离、一二级分离、二级一次关机、二级二次启动、二级二次关机、上面级组合体分离,以及测控大厅响起的阵阵掌声,我国全新研制的新一代大型运载火箭长征-5在海南文昌航天发射场托举着远征-2上面级和实践-17卫星,经过约1783s的飞行,成功进入预定轨道。长征-5的首飞成功标志着我国历时10年研制的大型低温运载火箭的工程研制成功,也标志着我国从此步入了拥有大型火箭国家的行列,还标志着我国由航天大国向航天强国迈出了最为坚实的一步。
On the night of November 3, 2016, “5,4,3,2,1, fire! ” Accompanied by the commander shout off, boost separation, the separation of the fairing, one or two separate, two shut down , Two secondary start-up, two secondary shutdown, the separation of the top-level combination, as well as the buzz of buzzing in the control hall. A new generation of large-scale launch vehicle Long March -5 developed at the Hainan Wenchang Space Launch Site held an expedition -2 Top level and practice -17 satellites, after about 1783s flight, successfully entered the scheduled orbit. The success of the first flight of the Long March -5 marks the successful development of a large-scale low-temperature launch vehicle developed in China for 10 years and marks the beginning of our country’s entry into the ranks of large rocket countries. It also marks China’s transition from a space power to a space-based nation Out of the most solid step.
