2020年5月30日，星期六，在佛罗里达州肯尼迪航天中心，SpaceX Demo-2任务的猎鹰9号火箭搭载着龙飞船从39A发射场发射升空，宇航员罗伯特·贝恩肯和道格拉斯·赫尔利将随火箭前往国际空间站。这次发射是SpaceX公司的龙船和猎鹰9号火箭首次作为该公司商业宇航员计划的一部分发射到国际空间站。这次试飞是SpaceX宇航员运输系统的端对端演示。贝恩肯和赫尔利于美国东部时间5月30日下午3点22分在肯尼迪航天中心39A发射中心发射升空。自2011年航天飞机计划结束以来，美国宇航员再次从美国本土到近地轨道的美国火箭上再次发射，人类太空飞行的新时代将开始。 来源：NASA/Bill Ingalls NASA的宇航员们有史以来第一次在美国本土通过一艘商业建造和操作的美国载人宇宙飞船发射升空，前往国际空间站。美国东部...
The Susquehanna River cuts through the folds of the Valley-and-Ridge province of the Appalachian Mountains in this photograph taken by the crew of the International Space Station. The Valley-and-Ridge province is a section of the larger Appalachian Mountain Belt between the Appalachian Plateau and the Blue Ridge physiographic provinces. The northeast-southwe...
On the northwestern coast of Madagascar, the salty waters of the Mozambique Channel penetrate inland to join with the freshwater outflow of the Betsiboka River, forming Bombetoka Bay. Numerous islands and sandbars have formed in the estuary from the large amount of sediment carried in by the Betsiboka River and have been shaped by the flow of the river and t...
