2015年7月2日报道,美国航天局(NASA)近日首次向外界展示了一架火星飞机原型设计,预计该型飞机将在2020年翱翔于火星的天空中。
NASA的火星飞机名为普朗特-M,外形好似“回旋镖”,官方计划于今年晚些时候利用一只探空气球将火星飞机发射升空进行模拟测试。NASA表示,普朗特-M的设计工作还远未完成,其最终将拥有可以折叠的双翼,并由3UCubeSat火星探测器运载飞向火星。
当3UCubeSat火星探测器进入火星轨道之时,将向火星地面方向喷气以减缓速度,这时普朗特-M将随气流被喷出,降落到火星大气层内,然后展开飞翼进行约10分钟的滑翔。滑翔过程中,机载相机将发送高分辨率地形照片给科学家,帮助他们寻找未来火星宇航员适合的着陆点。
