2015年的今天,蓝色起源火箭成功着陆,并创造历史。完全重复使用是一项颠覆性的突破,並成为第一枚成功飞入太空并返回地球进行受控垂直着陆的火箭。
在德克萨斯州西部的发射场,蓝色起源公司的“New Shepard”号航天器成功升空,达到预定的100.5公里测试高度,然后顶着约190公里/小时的高空侧风,在距离发射台中心仅约1.4米的地方平稳可控地着陆。
该航天器由两部分组成:宇航员乘坐的载人舱和由一台美国制造的BE-3液氢液氧发动机提供动力的火箭助推器。
发射时,BE-3发动机可提供11万磅的推力。动力飞行结束后,载人舱与助推器分离,滑行进入太空,提供数分钟的失重体验。载人舱下降过程中,宇航员将 再次进入大气层,之后展开三顶主降落伞进行着陆。
与此同时,助推器在制导飞行模式下下降至着陆台。着陆前,助推器再次点火BE-3发动机,将速度降低至4.4英里/小时,实现平稳的动力垂直着陆,从而确保航天器的可重复使用性。
Blue Origin's 2015 milestone with the New Shepard rocket marked a turning point in spaceflight technology, demonstrating the feasibility of fully reusable rockets to drastically reduce launch costs. The spacecraft consists of two main parts: the crew capsule designed for astronaut safety and comfort, and the booster powered by Blue Origin’s BE-3 engine, which uses liquid hydrogen and liquid oxygen as propellants. At launch, this engine provides an impressive thrust of 110,000 pounds. After the powered ascent, the capsule separated, allowing passengers to experience several minutes of microgravity before safely returning to Earth with the aid of three main parachutes. Simultaneously, the booster performed a precise, computer-controlled descent. It reignited its BE-3 engine to decelerate to a landing speed of just 4.4 mph amid challenging 190 km/h winds, landing within 1.4 meters of the launch pad. This precision underlines the advancements in guidance and control systems critical for booster recovery. Successfully achieving vertical takeoff and landing—VTOL—has paved the way for new possibilities in commercial spaceflight, enabling rapid reusability and shorter turnaround times between launches. This achievement predates similar feats by competitors, highlighting Blue Origin’s technical leadership. The use of liquid hydrogen engines like BE-3 also emphasizes environmental considerations by utilizing cleaner propellants. For space enthusiasts and the general public, the New Shepard mission symbolizes humanity’s step towards accessible space tourism and more sustainable space exploration. It also offers valuable insights into how rocket technology continues evolving to balance performance, safety, and reusability. The historic nature of this event is commemorated every year as a landmark in aerospace innovation, representing both engineering excellence and a vision for the future of commercial space travel.
