This week, we'll convene some of America's leading scientists, engineers, innovators and students in Pittsburgh to dream up ways to build on our progress and find the next frontiers. Just five years ago, US companies were shut out of the global commercial launch market. Today, thanks to groundwork laid by the men and women of NASA, they own more than a third of it. More than 1,000 companies across nearly all 50 states are working on private space initiatives.
本周,我们将在匹兹堡召集一些美国顶尖的科学家、工程师、创新人士和学生,一起设想我们该如何继续进步下去,并找到下一个挑战的目标。仅仅五年以前,在全球商业火箭发射市场上,美国企业还被人拒之门外。而如今,多谢NASA工作人员的兢兢业业,我们已经占领了全球市场的三分之一。在全美将近50个州里,已经有超过1000家企业正在开展私人太空探索工作。
We have set a clear goal vital to the next chapter of America's story in space: sending humans to Mars by the 2030s and returning them safely to Earth, with the ultimate ambition to one day remain there for an extended time. Getting to Mars will require continued cooperation between government and private innovators, and we're already well on our way. Within the next two years, private companies will for the first time send astronauts to the International Space Station.
为了翻开美国太空探索的新篇章,我们已经设立了一个清晰的目标:在本世纪30年代之前,把人类送上火星,然后再让他们安然无恙地返回地球;同时还要抱有更大的雄心壮志,有朝一日让宇航员在火星上停留更长时间。要想实现火星之旅,政府和私营创新企业之间需要展开进一步合作,而我们已经在这方面着手努力了。在接下来两年内,私营企业将首次把宇航员送上国际空间站。
