2020-11-23 [3004]

since the end of the 30-year us space shuttle programme in 2011,Manned space flight has dwindled to a series of mundane but bone-shaking自2011年美国结束为期30年的航天飞机计划以来,载人航天飞行只剩下俄罗斯火箭前往低轨道运行的国际空间站的一系列奇怪而动摇的航天巴士航行。True,Nasa,still by far the world ' s largest space agency,is developing a new generation of manned space craft But a working prototypy但是,使用可用的原型将需要很多年,Logically,this hiatus should provide An opportunity to rethink the whole purpose of sending people into space,An environment这个间隔我们正在反思将人类送入太空究竟意味着什么,但宇宙环境非常险恶。

这意味着飞往地球大气的航行要确保一点安全,必须投入相当大的资金。but too many Americans still feel a compulsion to spend billions of tax dollars on manned space flight for a re-evaluation to be politically feasion,但是美国When,in 2010,president Barack Obama scrapped the constellation programme that would have taken the us back to the moon by the next decadeThe storm of protest was intense。2010年美国总统巴拉克奥巴马(Barack Obama)停止了下一个10年重返月球的星座计划,引发了引起反感的抗议浪潮。the latest to capitalise on the inchoate desire to slip earth ' s surly bonds is the silicon valley entre preneur,Elon Musk。

最近硅谷企业Elon Musk(ELON Musk)是硅谷企业家Elon Musk(ELON Musk),他希望摆脱利用人类仍处于初期阶段的欲望。他明确提出了复活《星际迷航》梦想的计划:he has come forward with a plan to revive the dream of inter planetary travel,Proposing a reusable space ship that he estimates the在地球和火星之间来回3个月,建造可重复使用的宇宙飞船,从2020年到2030年之间的某个时间点开始运行。

this would be the first step to building a larger fleet and ultimately establishing colonies on other planets In Mr musk ' s view,that could allow.These are,of course,intoxicating visions . but they also raise questions about the merit of prioritising what remains,surely。A very long-term objective。这种愿景当然令人着迷,但仍然很怀疑把未来的目标作为优先事项,处理对与错。

Mr musk ' s project depends on technologies not yet in existence,Whether propulsion systems or the means to protect any interplanetary craft it would require partnerships with the public sector-not least Nasa-that could cost very many billions of tax payers ' money Then there此外,计划结束后,可能会影响人们对未来较长时间载人宇宙飞行的信任。《It is worth remembering that SpaceX ' s own record is not flawless》。

要忘记,spacex本身的记录并不高。two of its unmanned rockets recently blew up,one during a routine refuelling exercise earlier this month。该公司最近销毁了两枚无人驾驶火箭,其中一枚是本月初开始加油的,There is nothing wrong about bringing in private sector capital and know-how to back space exploration。

引进私营部门资本和技术支持宇宙勘探。Mr musk's SpaceX has,through some clever innovations,helped to bring down the cost of putting unmanned payloads into space But manned spp但是,根据对相关科学优势(经常被认为是该领域研究的正当理由)的合理评价,载人航天飞行仍然是豪华的尝试。if past funds had instead been invested in unmanned exploration And space science,we would know far more about our solar system,And indeed the过去,如果用这一领域的资金投资于无人探索和宇宙科学,我们对太阳系,甚至宇宙的了解不会比现在多。

Apart from national pride,the real reasons for manned space flight are those outlined by Mr musk in his presentation Advocates talk about the bened支持者谈论国际合作的好处和对年轻人的鼓励。But above all,there is The human spirit of adventure,The idea that our manifest destiny is to move out from The earth to explore-and ultilties但是This long-term vision lay behind Apollo in the 1960s and also underpins Mr musk ' s inter planetary vision .这一未来愿景不仅是20世纪60年代阿波罗计划启动的幕后,也是While many people will now regard it as more fantastic than inspiring,it remains the best justification for sending people:凯旋门国际平台首页。
