中国载人航天工程首次应急发射任务近日圆满完成。当神舟二十二号飞船精准对接空间站天和核心舱 时，中国载人航天用16天应急发射的硬核表现，给出了何为"值得信任"的最佳答案。 应急发射的执行难度，堪称对航天系统的"极限大考"。 此前，常规发射流程需30天。16天应急发射任务具有流程紧凑、强度大、节奏快等特点，而且是首次开 展，给飞船系统带来了很大考验。但中国航天人通过精简非必要测试、优化船箭地联合检查流程，在确 保测试全面性的前提下实现了效率突破，用实战证明了应急体系的可靠性。 值得一提的是，除了16天方案，中国载人航天工程还备有8.5天应急发射方案。如果空间站或航天员出 现重大突发紧急情况，我国将果断采用8.5天应急发射方案，帮助航天员尽快返回地面。也就是说，面 对此次"极限大考"，我们还留有余力。 这场"大考"的顺利通过，彰显了中国航天系统的三大核心优势。 其一，"发一备一"的滚动备份模式构筑了安全底线。一直以来，中国载人航天工程都采用"发一备一"的 滚动备份模式。神舟二十一号发射时，神舟二十二号早已出厂待命，这为快速响应提供了硬件基础。 其二，"众志成城"的多系统协同能力奠定了成功基石。发现险情后的20天时间 ...
