scroll 0 1 据报道，美国太空探索技术公司“星舰”飞船当地时间9月28日实现首次地球轨道飞行，但由于上升阶段发动机提前关闭等情况，任务团队决定缩短“星舰”在轨飞行时间，较原计划提前结束。CNN称，太空探索技术公司在今天的任务中取得了一些重大成果，但也出现了一些令人担忧的时刻。该公司目前仍面临发动机可靠性问题。
据报道，在本次任务中，“星舰”经历了迄今最剧烈的一次重返大气层过程。它以超过20倍音速的速度冲入地球大气层，虽然最终成功返回，并在太平洋预定地点完成受控溅落，但着陆过程不如上次任务那样平稳。现场视频显示，“星舰”受控溅落时发生了剧烈爆炸。
英国广播公司（BBC）称，太空探索技术公司通常希望其火箭和航天器能够重复使用，且回收助推器和返回舱有助于分析飞行过程中发生了什么，但由于本次“星舰”着陆时发生如此剧烈的爆炸，这可能无法实现。 0 | | | |
