据悉，这是我国空间站在轨建造阶段的首发航天器， 将为神舟十四号乘组三名航天员6个月的在轨驻留、空间站组装建造提供物资保障。 根据@我们的太空 官微介绍，在央视的直播镜头里可以看到， 有阵阵白色“烟雾”正笼罩着发射塔架，这是火箭进入加注阶段后出现的正常现象。 长征七号火箭使用的是液氧、煤油推进剂。 对于液氧来说，处在常温下的火箭是高温体，如果强行一次性将液氧注入火箭，效果就像将凉水泼到火炉里一样瞬间气化，这样会对火箭贮箱带来很大风险。 因此加注时一般会先小流量加注，逐步让火箭降温冷却，之后转入大流量加注、减速加注、停放补加等阶段后，火箭发射升空。 加注中，液氧会边加边排，空气中的水蒸气遇到排出的低温氧，就会形成水汽，看着像“烟雾”，这其实跟我们大热天吃冰棍时一个效果。
