Explanation: What’s happening in the sky? The pre-dawn sky first seemed relatively serene yesterday morning over Indian Harbor Beach in Florida, USA. But then it lit up with a rocket launch. Just to the north, NASA’s SpaceX Crew-2 Mission blasted into space aboard a powerful Falcon 9 rocket. The featured time-lapse video — compressing 12-minutes into 8-seconds — shows the bright launch plume starting on the far left. The rocket rises into an increasingly thin atmosphere, causing its plume to spread out just as it is lit by the rising Sun. As the Crew-2 capsule disappears over the horizon, the landing plume of the returning first stage of the Falcon 9 descending toward the SpaceX barge in the Atlantic Ocean can be seen. Up in space, the Endeavour crew capsule is expected to dock with the International Space Station (ISS) this morning, delivering four astronauts. The Crew-2 astronauts join Expedition 65 to help conduct, among other tasks, drug tests using tissue chips — small microfluidic chips that simulate human organs — that run rapidly in ISS’s microgravity.

说明: 天空发生什么事？这片美国·佛罗里达州·印地安港海滩上方的天空，在昨天日出前，原先相对宁静，然后因火箭发射而突然亮起。当时北方不远之处的国家航空和航天局之太空探索技术公司载人2号任务，在强大的猎鹰9号火箭推送下向天空攀升。在这部把12分钟过程压缩成8秒的缩时主题影片里，明亮的火箭发射烟尘自左缘启始。随着火箭深入越来越稀薄的大气层，受到朝阳照亮的火箭尘尾也随之扩展。当载人2号任务的乘载舱消失在地平线后方之后，可见到返回的猎鹰9号第一级火箭，曳着烟尘向大西洋上的太空探索技术公司泊船沉降。在进入太空后，奋进号的组员舱，预计今天早上会停靠并护送4位太空人到国际太空站（ISS）。这些载人2号乘员将加入第65探险队，协助各种事务的进行，包括用微型但可模拟人类器官的器官芯片(微流控芯片)，在ISS微重力让测试得以快速进行的环境中，测试各种药物。
