The next 50 years ofspaceflight will carry many challenges and surprises for explorers hoping toextend their reach into the cosmos. But it will also likely hold untappedriches for space science and spinoff technology that could, one day, catapulthuman and robotic explores beyond our own solar system and outward to otherstars.

未来50年的太空飞行将为探险家带来许多挑战和惊喜有希望扩展他们的足迹到宇宙空间。但它也将持有尚未开发的太空科学财富和剥离技术的可能,有一天,弹射人类和机器人探索我们太阳系之外并向外航行到其他恒星。

Exploiting the many resources of our solarsystem may enable humanity to venture beyond its confines for the first time,and blaze a trail to other stars.
开发许多太阳系的资源也许能够使人类首次冒险走出其活动范围之外,并开辟一条去往其他恒星的道路。
Building a spaceship that can travel to otherstar systems on human timescales & over the course of mere decades & will be achallenging and expensive proposition, with costs likely running into thehundreds of billions of dollars. But the economic and technological hurdleswon't be so steep if our species has begun tapping the vast riches locked up inasteroids and other bodies beyond Earth orbit, advocates say.
建造一艘在人类时间尺度（在短短几十年中）上可以航行到其他恒星系统的宇宙飞船将会是一个具有挑战性而且昂贵的命题,运行成本可达数千亿美元。但是如果我们物种已经开始开发被锁在小行星和地球轨道外的其他天体的巨量财富,经济和技术障碍就不会那么陡峭，拥护者称。
&A solar-system-wide economy couldkickstart research and development of the technologies that will allow us toengage in interstellar flight,& said Richard Obousy, president of IcarusInterstellar, a nonprofit group devoted to pursuing interstellar spaceflight.
&一个泛太阳系的经济可以启动技术的研究和开发,将允许我们从事于星际飞行,&致力于追求星际飞行的非营利组织&伊卡洛斯星际&的总裁理查德&奥博赛说。
Light-yearsaway
数光年以外
Interstellar flight is so daunting because ofthe vast distances separating stars. The extrasolar system closest to us, forexample, is the three-star Alpha Centauri, which lies about 4.3 light-yearsaway, or more than 25 trillion miles (40 trillion kilometers).
星际飞行十分艰巨,因为恒星相距遥远。例如，距离我们最近的太阳系外星系是三星系统的半人马座阿尔法星,位于约4.3光年外,或超过25万亿英里(40万亿公里)。
Thefarthest-flung spacecraft ever launched from Earth is NASA's Voyager 1 probe,which has covered about 11.3 billion miles (18.2 billion km) since blasting offin 1977. But it would take Voyager 1 roughly 70,000 more years to reach AlphaCentauri, and its newly discovered Earth-size planet, if the probe were headedtoward that particular system (which it isn't).
曾经从地球上发射的飞得最远的航天器是美国宇航局的&旅行者&1号探测器,自从1977年发射升空以来，它航行了约113亿英里(182亿公里)。但&旅行者&1号要花大约70000年的时间才能到达半人马座阿尔法星,如果探测器是朝向这个特定星系，它会发现新的地球大小的行星(其实不然)。
Sotraditional chemical-propulsion technology, such as that used by Voyager 1 andother spacecraft plying the solar system today, is just not going to cut it forinterstellar flight.
所以传统的化学推进技术,比如旅行者1号和今天通过太阳系的其他航天器,对星际飞行来说将不会仅仅是削减它。
&We need to start looking at alternativesif we're ever going to bring into reality some of the stuff that we've beendreaming about and that makes up a staple of science fiction & how to explorethese new worlds beyond the solar system,& Obousy .
&如果我们想要使一些我们一直在梦想中的东西和科幻小说的常见场景&&如何探索这些新的太阳系以外的世界成为现实,那么我们需要开始寻找替代品,&奥博赛告诉说。

Possible alternatives include harnessingthe power of nuclear fusion or matter-antimatter reactions. Or a probe couldcruise through space like a boat through the ocean, propelled by super-focusedlight beamed from the environs of Earth onto a gigantic sail.
可能的选择包括利用核聚变或物质-反物质反应的力量。或一个探测器可以巡航太空就像是一艘船穿过海洋,由来自地球附近聚焦的超级光束到一面巨大的帆上推进。
Suchapproaches could accelerate a spacecraft to some appreciable fraction of thespeed of light. But engineers may even be able to achieve faster-than-lighttravel by manipulating the fabric of space-time, creating a long-sought&warp drive.&
这种方法可以加速宇宙飞船达到某种可观的部分光速。但工程师们甚至可以通过操作时空结构创建一个长期寻求的&翘曲航行&实现超光速旅行。
Researchers had thought that such a warp drivewould require a power source with the minimum mass-energy of the planetJupiter. But recent calculations by Harold &Sonny& White, of NASA'sJohnson Space Center in Houston, suggest that some design tweaks could bringthat figure down to the mass-energy of a spacecraft like Voyager 1, whichweighed 1,800 pounds (815 kilograms) at launch.
研究人员曾认为,这样一个翘曲航行需要一个最小为木星的质量-能量的力量源。但是最近通过美国宇航局位于休斯顿的约翰逊空间中心的哈罗德&&桑尼&&怀特的计算,表明改进一些设计可以使这一数字下降到一艘像旅行者1号的飞船的质量-能量,也就是说发射重量为1800磅(815公斤)。
&I might have moved this idea fromimpractical to plausible,& White, who is also an Icarus Interstellar teammember, . He and his colleagues are now building a small tabletopexperiment as a first-step &existence proof& of the idea.
&我也许把这个想法从不切实际变得似是而非,&同为&伊卡洛斯星际&团队成员的怀特告诉说。他和他的同事正在构建一个小型桌面实验作为第一步该想法&存在的证据&。
Asolar system economy
一个太阳系经济
Noneof these advanced propulsion technologies are close to flight ready, so anyeffort to build an interstellar spacecraft will require a lot of research anddevelopment work.
没有这些先进的推进技术接近飞行准备,因此任何建造一艘星际飞船的努力将需要大量的研究和开发工作。
Thecosts will thus be quite high. While stressing the difficulty of estimating potentialprice tags at this early stage, Obousy ventured that an unmanned interstellarprobe might cost several times more than the $100 billion International SpaceStation. And a crewed vehicle could top $1 trillion.
这个成本将是非常高昂的,因此同时强调了在早期阶段评估潜在的价格标签的困难，奥博赛冒着一个无人星际探测器可能会花费超过价值1000亿美元的国际空间站数倍成本的风险。并且一枚载人运载火箭可能花费超过1万亿美元。

Those numbers might be off-putting to manygovernments, especially in these tough fiscal times. But tapping the riches ofthe solar system could help change things, Obousy said.
这些数字可能会不利于许多政府,特别是在这些艰难的财政时代。但利用太阳系的财富可以帮助改变这一切,奥博赛说。
Asteroid mining is a good example. Scientistshave estimated that a single near-Earth asteroid, the 1.5-mile-wide (2.5 km)Amun 3554, contains $20 trillion worth of platinum and other metals.
小行星采矿是一个很好的榜样。科学家估计一颗单独的近地小行星,1.5英里(2.5公里)宽的&阿蒙&3554,包含价值20万亿美元的铂和其他金属。
Suchfigures have enticed two separate companies, Planetary Resources and Deep SpaceIndustries, Inc., to get into the asteroid-mining business within the last ninemonths. Both firms plan to extract from asteroids not only metals but alsowater, which can be split into its constituent hydrogen and oxygen & the chiefcomponents of rocket fuel.
这些数据已吸引两家独立的公司,&行星资源&和&深层太空产业&公司,在过去九个月内进军小行星采矿业务。两家公司都计划从小行星不仅提取金属还提取水，水可以裂解成它的组成成分氢气和氧气&&火箭燃料的首选。

If all goes according to plan, thecompanies' work could lead to the establishment of an in-space manufacturingindustry that builds habitats, satellites and other spacecraft away from ourplanet. Asteroid mining could also help set up off-Earth &gasstations& that allow traditionally fueled craft to top up their tankscheaply and efficiently.
如果一切按计划进行,该公司的工作可能引领一个建造远离我们的星球的栖息地、卫星和其他航天器的太空制造行业的确立。小行星采矿也可以帮助建立地球外的&加油站&,允许传统燃料的飞船便宜高效地加满他们的油箱。
These developments would help humanityextend its reach throughout the solar system, a necessary step along the pathto interstellar flight, experts say.
专家认为这些进展将帮助人类扩展到整个太阳系,这是顺着星际飞行的途径的一个必要的步骤。
&I think before we ever reallyundertake sending something to another star, we will probably have to bemasters of our own solar system,& Les Johnson, deputy manager of theAdvanced Concepts Office at NASA's Marshall Space Flight Center in Huntsville,Ala. (and also an accomplished science-fiction writer), .
&我认为在我们真的保证能够发送某些东西到另一颗恒星之前,我们可能需要征服我们自己的太阳系,&位于阿拉巴马州的美国宇航局马歇尔太空飞行中心的高级概念办公室的副主任莱斯&约翰逊(还是一位成功的科幻作家)告诉说。
Obousy voiced similar sentiments, pointingout the economic importance of such a big footprint.
奥博赛也表达了类似的观点,指出这么大的覆盖区域的经济的重要性。
&If we can become a civilization thathas vast resources at its disposal & orders of magnitude more than we havetoday, as a product of space exploration, space mining and thesolar-system-wide economy & then we may reach a stage where an interstellarmission doesn't actually cost us that much in the bigger scheme of the grossdomestic product of the solar system,& he said.
&如果我们能成为一个有巨大的资源可供支配的文明&&数量级比我们今天拥有的多很多,作为一个太空探索、太空采矿和泛太阳系经济的产物,接下来我们可能会达到一个实际上并不花费我们太多在更大的太阳系GDP方案中的星际任务的阶段,&他说。
Flyingto another star by 2100
到2100年飞到另一颗恒星
Icarus Interstellar aims to help humanityachieve interstellar flight by the year 2100. Obousy said he believes that thiscan indeed happen, despite the economic and technological hurdles that must beovercome.
&伊卡洛斯星际&旨在帮助人类到2100年实现星际飞行。奥博赛说他相信这确实会发生,尽管有经济和技术障碍需要被克服。
One reason for optimism is the ongoingexoplanet revolution, which has shown that our Milky Way galaxy is teeming withplanets. Researchers have confirmed more than 800 worlds beyond our solarsystem, and scientists estimate that billions more are out there.
一个乐观的理由是正在进行的系外行星革命,这表明我们的银河系充满了行星。研究人员已经证实了在我们的太阳系外有超过800个世界,并且科学家估计有上亿颗行星在那里。
Astronomers have confirmed aplanet in the Alpha Centauri system and detected five potential worlds circlingthe star Tau Ceti, just 11.9 light-years away. That includes two that might bein the star's habitable zone, the range of distances from a star in whichliquid water could exist on the world's surface.
天文学家已经证实行星在半人马座阿尔法星系有一颗行星，并检测到五个围绕鲸鱼座&星运行的潜在的世界,仅仅在11.9光年外。这当中包括的两个可能位于恒星的宜居区内,即距恒星距离确保液态水存在于该世界的表面的范围。
The discovery of the first true &alienEarth,& a planet the size of our own in its star's habitable zone, couldhelp build a groundswell of public support for interstellar spaceflight, Obousysaid. Our species might want to examine such a world up close for any signs oflife. The detection of electronic signals from an intelligent aliencivilization could have a similar galvanizing effect.
第一个真正的&外星人的地球&（一颗在其恒星的宜居区内且大小和我们的地球差不多的行星）的发现, 可以帮助建立一个关于星际飞行的高涨的公众支持,奥博赛说。我们的物种可能想要检验如此接近的世界的任何生命的迹象。探测来自一个智慧外星文明的电子信号可能会有一个类似刺激的效果。
Overall, Obousy thinks humanity has a goodshot of launching its first interstellar mission by the end of the century. Asan example of our species' potential, he points to how quickly air travelbecame routine after the Wright brothers' ramshackle first flight in 1903.
总的来说,奥博赛认为到本世纪末人类就会具有一个良好的发射手段来执行第一次星际任务。作为一个我们人类的潜力例子,他指出在莱特兄弟在1903年进行的摇摇欲坠的首飞之后,航空旅行是如何迅速成为常态的。
&I think a lot of people tend tooverestimate what we can accomplish in the short term, in the next five to 10years,& he said. &But they also vastly underestimate what we canaccomplish in the long term, decades or a century from now.&
&我认为很多人倾向于高估我们在短期内（在未来的5到10年）可以完成的事情，&他说。&但他们也大大低估我们从长远来看（几十年或从现在开始一个世纪）可以完成的事情。&

&Overall, Obousy thinks humanity has agood shot of launching its first interstellar mission by the end of thecentury. As an example of our species' potential, he points to how quickly airtravel became routine after the Wright brothers' ramshackle first flight in1903.&
Modern aircraft are completely analogous tothe Wright's first aircraft. Internal combustion engines burning petrochemicals and oxygen from the air, spin airscrews, which create thrust thatpropels the craft forward, gaining lift from the shape and angle of attack ofthe wings moving through the air, and stabilizing itself via secondarysurfaces.
No such analog exists for an interstellarcraft. In terms of interstellar flight, we're still a LONG way from 1903, andit's impossible to say how far.
Nothing against mining asteroids andcontinuing to explore and populate THIS system, mind you. That's all great.But, while the expertise in building trillion dollar space structures would nodoubt come in handy in constructing an interstellar craft, it's not the majorthing holding us back from doing it.

现代飞机完全类似于莱特的首架飞机。内燃机燃烧石油的化学物质和来空气中的氧,螺旋桨旋转产生推力推动飞机前进,从机翼的形状和迎角获得升力在空中移动,并通过第二表面稳定机体本身。
星际飞船没有这样类似的存在。在星际飞行方面,我们从1903年开始还有很长的路要走,而且不可能说出能走多远。
提醒你没有这种针对开采小行星和继续探索以及移民的系统。所有的一切都很伟大。但是,虽然专业知识在建造上万亿美元的太空建设上将毫无疑问建造一艘星际飞船上派得上用场,没有掌握的主要因素会制约我们这样做。

Right, the main thing holding us back is the research anddevelopment we need to do, As the craft is going to be operating in microgravor zero G environments, the research for the drive systems probably need to becarried out in similar environments.
So, asteroid mining will enable us to build larger, more complexresearch facilities, which could lead to perfection of a method forinterstellar flight.

Aaron Labertew That's just pure speculation. Maybe there IS no suchthing as FTL. And if there is, who's to say you can't develop it on a desktop?We just don't know. Advances in physics theory can't be brought on by royaldecree. All the king's horses... etc.
But yes, FTL isn't much use to you if you can't even build aself-sustaining space station. So I'm all for getting to work on THAT. But, asusual, this article is way off in the picture it paints.
And besides, once you can live in space for indefinite periods oftime, who needs other Earths anyway? Planets are dangerous places. Volcanoes,earthquakes, hard to move out of the way of incoming comets and gamma raybursts. Habitations in stellar orbit is probably where our near future lies.Right here in the good old Sol system.

Aaron Labertew，这只是纯粹的推测。也许超光速是不存在的。如果有,谁告诉你不能在桌面上开发它呢?我们只是不知道。物理学理论的进步不能由皇家法令比如国王的马等带来。
但是，是的, 如果你甚至不能构建一个自给自足的空间站,超光速对你就没有多大用处。所以我所有的工作都是关于这个。但是,像往常一样,这篇文章是离它在图中所画的还很远。
此外,一旦你可以在任何时候住在太空中,谁还需要另一个地球呢?行星是个危险的地方。火山、地震、努力搬离来袭的彗星路径以及伽马射线暴。在恒星轨道中的住处在不远的将来可能找到。就在这古老的太阳系里。

As much as I hate to say it, the maindriver that will push us out into space, is how much money can be made from it.Ventures like asteroid mining, mining on the moon, zero-G manufacturing, spacebased shipyards, etc. are what is going to get us out into space once and forall. Agencies like NASA and other governmental space agencies simply do nothave the $$$ to make this happen, probably not ever. That is not their reasonfor being and politics, graft, etc. will keep them from filling such a role. Inthe future, a player like NASA will have a limited role at best in space. Infact, I'm not real sure what role NASA would play say 20 - 30 years from nowand going forward when there will be so many commercial players in the spaceexploration/exploitation game. Perhaps NASA can be the ones who are the pointof the spear in our exploration of space. But, if we are going to leave ourchildren a true space faring society, we will need to look to the privatesector to make that happen.

I agree. I'm as big a NASA fan as they come, but the NASA model ison the verge of unsustainability. Space travel has progressed to the pointwhere the economics must make sense for many large, long-range projects. Asmuch as I'd like to see it, we just don't have the political will to spend whatit will take to apply the Apollo model to the rest of the solar system. Exceptfor pathfinding and pure research, space from this point on in our history ispretty much going to be a pay-as-you-go proposition.

我同意。我从前是一个美国宇航局的大粉丝,但美国宇航局模式处于不可持续的边缘。太空旅行已经进展到一定地步,经济学必须对于许多大型、远程计划有意义。我想尽可能多地看到它,我们只是没有政治意愿应用阿波罗模式向太阳系的其他星球进发。除了探险和纯粹的研究、在我们的历史上从这点上来说太空几乎将成为一个花费多少就走多远的议题。

Nasa can be like Discovery Channel - just go there and study thestuff that doesn't make money, but is of great interest to the rest of us.

That is exactly what NASA should be doing, and if the politicianswill allow it and give the commercial space industry a very modest boost to getthem started, that is exactly what we could have.

这正是美国宇航局应该做的,如果政客们会允许这样做，并给与商业太空产业非常温和的推动来启动他们,这恰好是我们可以有的。

Yeah, that's pretty much what the article is saying. But justbecause we're doing things one step at a time doesn't mean we can't think aboutthe next step or the step after that right now.

是的, 文章说的差不多就是这样。但仅仅因为我们做事一步一个脚印并不意味着我们不能想想下一步或今后的步骤。

Very exciting prospects, Iwant to get involved in space exploration. Vulvox Nanobiotechnology Corporationhas reports on laser fusion technology that can be adapted to power star ships,the worlds lightest toughest strongest materials for constructing space craftand a kinetic impact fusion rocket engine that can also hit asteroids withkinetic impact armatures to change their orbits away from Earth. We also havepictures on our website of our novel carbon nanotube adhesive that can be usedto reversibly and repeatedly hold weightless astronauts to the walls of thespace station. and Contact Neil Farbstein at .

Before we do anything we must figure outhow to recreate gravity otherwise our bodies will become jelly. Astronauts haveirregular bowel movements due to the weightlessness of space. A spinningcylinder won't do it... Recreating gravity will me a major step forward.Support CERN!

Actually only in theory. How large, how long and how often can noteven be determined until one is made for research. We yet determined if gravityis the cause of other problems with the detrition of the human body either.

实际上只有在理论中是这样。甚至无法确定需要多大、多长和多久直到通过研究制造一个出来。我们还未确定是否重力是其他人体损耗问题的原因。

If we figure out a way to store enough energy (nuclear fusion), thenwe could accelerate constantly at 9.8 m/s^2 (1g) and then reverse the machineand decelerate at -9.8 m/s^2 (-1g). We already know how to do this, just howfar of a trip do we need to make and how much fuel do we need to store?

如果我们找到一个方法来储存足够的能量(核聚变),那么我们可以以9.8米/秒^ 2(1 g)不断加速,然后倒转机器并以-9.8米/秒^ 2(1 g)减速。我们已经知道如何做到这一点,只要知道我们需要的旅行多远就可以我们需要存储多少燃料?
