    NASA's New Rocket Delayed

    美国国家航空航天局大火箭升空计划推迟

    NASA's large new rocket will not be ready for launch next year, the American space agency's top official said this week.

    美国宇航局高级官员?#23616;?#34920;示,美国国家航空航天局的新型大型火箭将不会在明年发射。

    NASA Administrator Jim Bridenstine told a Senate committeethat he is thinking about using rockets made by private companies to keep the planned June 2020 launch date.

    美国国家航空航天局局长吉姆·布里登斯廷向?#25105;?#38498;委员会表示,他正在考虑使用私营公?#23616;?#36896;的火箭来保证2020年6月的发射如期进?#23567;?/p>

    NASA's delayed rocket is called the Space Launch System, or SLS.

    美国国家航空航天局的延迟发射的火箭?#24576;?#20026;太空发射系统,简称SLS。

    It's a "critical piece of what NASA needs to build," Bridenstine told the Senate Commerce, Science and Transportation Committee.

    布里登斯廷对?#25105;?#38498;商业、科学和运输委员会说,这是“NASA需要建造的关键部分”。

    Bridenstine added that NASA would need two private rockets to take over the SLS' job of launching the Orion capsule and an upper stage.Orion must dock with the upper stage in orbit around Earth before going to the Moon.

    布里登斯廷补充说,NASA将需要两枚私企制造的火箭来接替SLS的任务-发射猎户座太空舱和一个上层火箭。猎户座在登月前必须与地球轨道上的上层火箭对接,然后才能进入?#34385;頡?/p>

    This is 2019, Senator Roger Wicker, the committee chairman, told Bridenstine."I'd sure like to keep us on schedule."

    “现在是2019年,”委员会主席、?#25105;?#21592;罗杰·威克对布里登斯廷说。“?#19994;?#28982;希望我们能如期进?#23567;?rdquo;

    The first test flight had been planned for this year."I want to be clear: NASA has a history of not meeting launch dates, and I'm trying to change that," Bridenstine said.

    首次试飞本来计划于今年进?#23567;?#24067;里登斯廷说:“我想澄清一点:美国国家航空航天局有不按时发射的历史,我正在努力改变这一点。”

    NASA seeks a sustainable moon program.In the past, Apollo lunar landings were direct trips from and back to Earth.The goal now is to have a base with astronauts near the moon.

    美国国家航空航天局希望其?#34385;?#39033;目能?#24576;中?#36827;?#23567;?#20197;前,阿波罗登月?#38469;?#26376;地直接往返的。现在的目标是在?#34385;?#38468;近建立一个宇航员基地。

    Orion would not carry a crew and would not land on the moon.Instead, the Orion would get close to the Moon before traveling beyond it.

    猎户座将不会搭载宇航员,也不会登陆?#34385;頡?#30456;反,猎户座飞船会先靠近?#34385;潁?#28982;后才会飞离?#34385;?#26356;远的地?#20581;?/p>

    A NASA statement says Orion "will travel 280,000 miles or 450,000 kilometers from Earth,thousands of miles beyond the Moon over the course of about a three-week mission."

    美国国家航空航天局在一份声明中表示,猎户座“将从地球出发飞行28万英里(45万公里),将在为期3周的任务中飞离?#34385;?#22806;数千英里的地?#20581;?rdquo;

    The statement adds, "Orion will stay in space longer than any ship for astronauts has done,without docking to a space station, and return home faster and hotter than ever before."

    声明还说,“猎户座飞船将在太空?#22411;?#30041;的时间比可载人飞船?#23478;?#38271;,而且不需要与空间站对接,返回地球的速度更快,温度也更高。”

    NASA is already using private companies to make International Space Station shipments.If private rockets were to be used for the 2020 mission, SLS would be put in operation for NASA's second exploration mission by 2023.

    美国国家航空航天局已经在通过私人企业制造国际空间站的运载火箭了。如果私人企业制造的火箭被用于2020年的任务,那么SLS将在2023年之前投入美国国家航空航天局的第二次空间探索任务?#23567;?/p>
