许多公司的目标是建造下一代高超音速客机。他们都没有使用与 Venus Aerospace 的 Stargazer 相同的技术。它使用传统的喷气发动机起飞，然后转换为旋转爆震火箭，以每秒 20,000 转的速度旋转，达到 9 马赫的速度。这架飞机打算在大约一小时内搭载大约 12 名乘客飞行近 7,000 英里的距离，在 170,000 英尺的高度——高到足以看到太空的黑暗和地球的曲率。该公司目前正在研发一架 20 英尺的原型无人机，希望能达到 5 马赫，然后开始建造全尺寸原型。
美国国家航空航天局在其整个历史中使用的标识和符号几乎与其成就一样具有标志性。这款黑色卡车式网帽采用其着名的标志设计，于1975年设计，绰号为“蠕虫”。该徽标于1992年退役，并用金色文字刺绣熨斗贴片装饰这顶帽子。这款5面板，高廓形后背帽采用轻质透气设计，为您的休闲外观增添怀旧气息。
