3月3日，这不是詹姆斯·韦伯太空望远镜拍摄的遥远星系星云的最新照片，这片由气体和尘埃组成的云团让太空沿岸的天文学家眼花缭乱。这张长焦快照是在猎鹰9号火箭发射到国际空间站后几分钟拍摄的。它捕获了分离的第一和第二阶段的羽流和废气，在黑暗的夜空中形成了一个漂流的罗夏墨迹图案。在令人惊叹的地面星云中，靠近底部中心的亮点是载人龙飞船“奋进号”第二级发动机的点火，它将携带4名宇航员前往太空。在它的上方，清晰的轮廓是猎鹰9号第一级助推器的定位，准备返回地球卡纳维拉尔角的着陆区。这个可重复使用的第一级助推器是第一次飞行。但“奋进号”载人飞船此前曾4次将人类送入近地轨道并返回。奋进号作为一艘宇宙飞船的名字，也被重新使用，比如退役的奋进号航天飞机和阿波罗15号指挥舱。

Not the James Webb Space Telescope's latest view of a distant galactic nebula, this cloud of gas and dust dazzled spacecoast skygazers on March 3. The telephoto snapshot was taken minutes after the launch of a Falcon 9 rocket on the SpaceX Crew-8 mission to the International Space Station. It captures plumes and exhaust from the separated first and second stages, a drifting Rorschach pattern in dark evening skies. The bright spot near bottom center within the stunning terrestrial nebulosity is the second stage engine firing to carry 4 humans to space in the Crew Dragon spacecraft Endeavour. In sharp silhouette just above it is the Falcon 9 first stage booster orienting itself for return to a landing zone at Cape Canaveral, planet Earth. This reuseable first stage booster was making its first flight. But the Crew Dragon Endeavour capsule has flown humans to low Earth orbit and back again 4 times before. Endeavour, as a name for a spacecraft, has also seen reuse, christening retired Space Shuttle Endeavour and the Apollo 15 command module.
