在今年的航天发射计划当中,有一个特别的亮点,就是我国将使用长征十一号固体运载火箭进行首次海上发射。近年来,许多国家对发射近赤道、低倾角卫星的需求越来越旺盛。发射这类卫星,离赤道越近,运载能力损失越小,发射成本越低。因此,在靠近赤道的海上进行火箭发射,成为许多航天强国争相开发的一种发射模式。航天科技集团一院长征十一号火箭副总指挥金鑫:我们现有的发射场最低纬度的就是文昌发射场,19度,所以说要更低纬度的就很难满足我们的发射需求。另外,进行海上发射,我们可以灵活选择发射点,同时解决了残骸落区安全性的问题。长征十一号火箭是我国首个通用型固体运载火箭,凭借快速、灵活的发射方式,能够适应与陆地完全不同的海上发射环境。金鑫:船在运动当中,我们会选择一个比较合适的点实施发射,而且长征十一号火箭是冷发射,它发射的速度非常快,起飞过后,我们的自控包括制导系统完全可以适应整个自动发射的方式。【长征八号将于今年完成研制】 此外,长征系列火箭的新成员——长征八号将于今年完成研制。作为新一代中型运载火箭,长征八号通过全新模块化设计和回收技术,使其具备很强的国际竞争力。航天科技集团一院长征八号火箭副总设计师吴义田:在长征五号、长征七号和长征三号甲系列火箭的基础上,长征八号进行快速集成,预计在2019年具备发射条件,在2020年左右实施发射。
