A group of aerospace engineers in NASA has made a persuasive pitch for an unexpected space-exploration option: Venus. 近日,美国国家航空航天局的一群航天工程师,使令人意想不到的太空探索地金星,变得极具说服力。 The team has sketched out plans for and conducted small-scale tests of a blimp-like airship that would ferry a crew of two on a month-long expedition above the Venusian cloudtops. 据悉,该团队已制定了计划,并对一艘飞艇式飞船进行小规模测试,这艘飞船将载着两名宇航员在金星云层上进行为期一个月的探险。 They point out that Venus is the closest, most accessible planet in the solar system. It's nearly identical to Earth in size and mass, making it an excellent place to learn about the prospects for life on other Earth-like worlds. 他们指出,金星是太阳系中距离最近且最易登陆的行星,它的大小和质量几乎与地球一模一样,使其成为了解其他类地行星生命前景的绝佳地点。 |
