据外媒BGR报道,美国宇航局(NASA)和SpaceX公司的合作即将进入关键时刻,自航天飞机时代以来,美国宇航局的第一批宇航员将从美国本土发射升空。SpaceX公司开发的载人“龙”飞船是NASA商业乘员计划的一部分,5月27日,这艘太空船将载着两名宇航员前往国际空间站。

对于SpaceX和NASA来说,这将是一个非常重要的日子,也是一个巨大的里程碑,但还有一个很大的问题没有解决:在这次SpaceX的首次载人航天发射中,宇航员Bob Behnken和Doug Hurley将在太空中停留多久?

正如Teslarati报道的那样,NASA仍在制定计划,还没有决定两人抵达后在轨道实验室中停留的时间。这次任务对SpaceX来说显然是一件大事,但NASA希望其宇航员在太空中也能完成一些工作。作为载人“龙”飞船的首次载人飞行,SpaceX公司很希望能将宇航员安全送入太空,然后迅速返回地球,从而完成NASA的认证,让公司能够全力以赴为未来的发射做准备。话虽如此,但要将人类送入太空并不容易,NASA也不想浪费这段旅程。

归根结底,这次首次载人发射仍然是一次测试。这是一次证明航天器能够安全有效地将科学家们送到国际空间站的证明。在下一次载人飞行的 "龙 "号飞船的载人飞行中,NASA将派出4名宇航员到空间站进行更长时间的载人飞行。理想的情况是,NASA希望这两项任务尽可能接近重叠。

“在让航天器快速返回完成认证和提供额外的乘员时间在空间站上进行维护和研究,这是一个权衡的结果,”NASA国际空间站项目经理Kirk Shireman在最近的一次简报会上说。“从空间站的角度来看,我们想做的是,尽可能地让他们在轨道上停留,直到Crew-1号航天器准备就绪,把Demo-2号航天器带回家,让认证工作完成,然后发射Crew-1号航天器。”

当然,这是以这次最后的演示任务一切顺利为前提。NASA肯定会给SpaceX公司做一些说明,也许会有一些它希望看到的小东西被处理或改变,但一旦航天器被NASA认证使用,它将正式为该太空机构服务。
