美国加州上空的火箭发射烟尘

空中发生了什么?在星期五,一艘发射升空的太空探索科技公司的火箭,在部分南加州和亚利桑那州的天空中,留下了相当美丽壮观的景象。这艘从加州朗玻克市附近的范登堡空军基地发射的火箭,其产生的烟尘有时看起来就像一只巨型太空飞鱼,在落日的背照之下显得十分明亮。这艘猎鹰9号重载火箭在极为短暂的一分钟发射窗口内,成功地将正在建构中的全球通讯网络的一部分,10部新时代卫星推送到近地轨道。在图片右侧,可以清楚地看到第一节火箭所产生的烟尘,而直冲云霄的上节火箭则位于左侧烟尘的顶点。本次火箭发射景观可参见这些精彩影片。以上这幅2.5秒曝光的主题影像,摄于加州橘郡。

SpaceX Rocket Launch Plume over California

Explanation: What’s happened to the sky? On Friday, the photogenic launch plume from a SpaceX rocket launchcreated quite a spectacle over parts of southern California and Arizona. Looking at times like a giant space fish, the impressive rocket launch from Vandenberg Air Force Base near Lompoc, California, was so bright because it was backlit by the setting Sun. Lifting off during a minuscule one-second launch window, the Falcon 9 Heavyrocket successfully delivered to low Earth orbit ten Iridium NEXT satellites that are part of a developing global communications network. The plume from the first stage is seen on the right, while the soaring upper stage rocket is seen at the apex of the plume toward the left. Several good videos of the launch were taken. The featured image was captured from Orange County, California, in a 2.5 second duration exposure.
