1997年8月20日凌晨1时50分,第二枚长征三号乙运载火箭在我国西昌卫星发射中心点火起飞,成功地将美国劳拉空间系统公司为菲律宾马部海卫星公司制造的马部海通信卫星送入地球同步转移轨道。至此,中国航天总公司所属的中国长城工业总公司与美国劳拉空间系统公司1995年5月29日签订的发射马部海通信卫星的合同圆满完成。这次发射的圆满成功,使我国又诞生了一种迄今为止地球同步转移轨道运载能力(GTO)最大的、第三级为液
At 1:50 am on August 20th, 1997, the second Long March III B carrier rocket took off at the Xichang Satellite Launch Center in China and succeeded in bringing the American Laura Space System Company to the Mabuhai Satellite Company of the Philippines. The maritime communications satellites are sent into geosynchronous transfer orbits. At this point, the contract signed between China Great Wall Industry Corporation, a subsidiary of China Aerospace Corporation, and Laura Space Systems of the United States, signed on May 29, 1995, to launch the Mabuhai communications satellite was successfully completed. The successful launch of this launch resulted in China’s birth of a third-level liquid with the largest GTO in the world so far.
