本期火箭报告探讨了自航天飞机时代以来,太空飞机在太空运输领域所扮演的角色。尽管美国空军的X-37B和中国的类似飞行器仍在运行,但它们都需要传统火箭的发射。维珍银河的亚轨道太空旅游平台也属于太空飞机。虽然太空飞机在外观上极具吸引力,但其额外的重量(机翼)在任务的最后几分钟才会派上用场。文章分析了太空飞机在可回收性和复用性方面的优势,以及与传统火箭相比存在的劣势,并探讨了太空飞机未来的发展前景。

🚀自航天飞机时代以来,太空飞机一直是太空运输领域的一个小众选择。美国空军的X-37B和中国类似飞行器是2011年以来仅有的入轨太空飞机,但它们依赖传统火箭发射。

⚖️太空飞机的优势在于其可回收性和复用性,但与SpaceX等公司的传统火箭相比,太空飞机需要携带额外的重量(机翼)进入太空,这部分重量仅在任务的最后阶段才发挥作用。

🌌尽管存在挑战,太空飞机在外观上具有独特的吸引力,并且在特定任务中可能具有优势。因此,太空飞机的未来发展仍然值得关注和探索。

Welcome to Edition 7.45 of the Rocket Report! Let's talk about spaceplanes. Since the Space Shuttle, spaceplanes have, at best, been a niche part of the space transportation business. The US Air Force's uncrewed X-37B and a similar vehicle operated by China's military are the only spaceplanes to reach orbit since the last shuttle flight in 2011, and both require a lift from a conventional rocket. Virgin Galactic's suborbital space tourism platform is also a spaceplane of sorts. A generation or two ago, one of the chief arguments in favor of spaceplanes was that they were easier to recover and reuse. Today, SpaceX routinely reuses capsules and rockets that look much more like conventional space vehicles than the winged designs of yesteryear. Spaceplanes are undeniably alluring in appearance, but they have the drawback of carrying extra weight (wings) into space that won't be used until the final minutes of a mission. So, do they have a future?

As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

One of China's commercial rockets returns to flight. The Kinetica-1 rocket launched Wednesday for the first time since a failure doomed its previous attempt to reach orbit in December, according to the vehicle's developer and operator, CAS Space. The Kinetica-1 is one of several small Chinese solid-fueled launch vehicles managed by a commercial company, although with strict government oversight and support. CAS Space, a spinoff of the Chinese Academy of Sciences, said its Kinetica-1 rocket deployed multiple payloads with "excellent orbit insertion accuracy." This was the seventh flight of a Kinetica-1 rocket since its debut in 2022.
