快速电波爆发(Fast radio burst,FRB)是种宇宙瞬态高能物理现象,通常起源自银河系外,然而澳洲一群天文学家近日发现,去年探测到一个FRB事件实际并非来自遥远天体,而是一颗目前正绕地球旋转的废弃卫星。 2024年6月13日,澳洲平方公里电波望远镜(Australian ...
NASA's X-59 Quiet SuperSonic Technology (QueSST) experimental supersonic aircraft took to the skies for the first time on October 28, 2025 from Lockheed Martin's famously secret Skunk Works at the US ...
此外,NASA发布了X-59飞机于10月28日首次试飞的图像和视频。此次试飞曾多次被推迟,最终在洛克希德·马丁公司赢得开发该飞机的合同9年之后才得以实现。NASA表示,该计划可能有助于推翻美国数十年来禁止民用超声速飞机在陆地上空飞行的禁令,并可能预示着超声速商业航空新时代的到来。
NASA's X-59 is taking slow steps towards supersonic flight, beginning taxiing tests at US Air Force Plant 42 in Palmdale, California. The final part of Phase One development, it's the precursor to ...
Breakfast in New York, midmorning snack in London. Taxi tests are underway on a highly anticipated supersonic plane designed to quietly break the sound barrier — and slash flight time between New York ...
Though 2025 is ticking away, NASA still aims to complete the first flight this year of its X-59 Quesst quiet-supersonic demonstrator, saying the team is progressing into high-speed taxi tests and ...
NASA's experimental X-59 quiet supersonic aircraft has begun low-speed taxi tests, marking the final stage before its inaugural flight later this year. The X-59's primary goal is to demonstrate ...
The Lockheed Martin X-59 Quesst, which stands for "Quiet SuperSonic Technology," is an experimental aircraft developed by Lockheed's legendary Skunk Works. That's the same organization that developed ...
据NASA官网介绍,X-59是一款试验性喷气式飞机,长约30米,翼展约9米,设计巡航速度为1.4马赫(即1.4倍音速),其独特的外形与降噪设计可大幅减弱传至地面的音爆声响。
