Interstellar-destination

Tau Ceti recently crashed into the headlines after it was announced that a system of five worlds maybe in orbit around the star. Although the exoplanets have yet to be confirmed,this discovery is profound in that one of the worlds, a "super-Earth"designated Tau Ceti "e" -- may be sitting inside the star's so-calledhabitable zone.

鲸鱼座τ星在被宣布是一个可能有5颗行星在轨道围绕恒星旋转的星系后，最近跌下了头条。虽然系外行星尚未得到证实，但是这一发现是意义深远的，其中一个行星，一个命名为鲸鱼座τ星“e”的“超级地球”——可能是坐落在恒星的内部轨道被称为可居住区的区域。

The habitable zone is considered the perfect location in a star's orbitfor a world to support liquid water (it's not too hot and not too cold), asubstance essential for the evolution of life as we know it.

可居住区被认为是完美的位于一个恒星支持液态水存在的世界的轨道（不太热也不太冷），一个据我们所知道的生命进化的必不可少的物质基础。

If this world is proven to exist -- follow-up studies by otherobservatories are required to confirm its orbit and size -- the 4.3 Earth-massworld will become famous for being the smallest world discovered within thehabitable zone of another star.

如果这个世界被证明是存在的——观测站的后续研究需要确认其轨道和大小——4.3倍地球质量的世界将变得以在另一颗恒星范围内被发现的拥有可居住区最小的世界而闻名。

Within Reach?

在可到达的范围内吗？

Not only is Tau Ceti's "super-Earth" a curious objective forastronomers to seek out extraterrestrial life, the nearby star could be withinthe reach of a future interstellar mission.

鲸鱼座τ星的“超级地球”不仅是一个天文学家寻找外星生命的奇妙目标，而且附近的恒星可能会在一个未来的恒星际航行任务到达的范围之内。

Tau Ceti may well be in our proverbial "cosmic backyard," but itis still 12 light-years from Earth. The energies and speeds needed to make ahypothetical (unmanned) probe a reality aren't possible using currenttechnologies, but according to Paul Gilster, co-founder of the TauZero Foundation and author of the book Centauri Dreams (andwriter for the blog of the same name), such a feat may not remain "impossible" for too long.

鲸鱼座τ星很可能会成为我们常说的“宇宙后院”，但它仍然离地球有12光年。做一个假设的（无人）探测需要的能量和速度在现实中是不可能利用现有技术的，但根据保罗·格里斯特，鲸鱼座τ星基金会的创始人之一和《半人马座梦想》的作者（与博客的作者笔名相同），这样的壮举也许不能保持太长时间的“不可能”。

"Pushing a 'lightsail' by beamed laser or microwave propulsion(leaving the 'fuel' at home) may be able to get us up to ten percent or so ofthe speed of light, which would give us a mission to Tau Ceti of a bit over acentury," Gilster told Discovery News.

“推着一个通过定向激光或微波推进（‘燃料’留在家里）的‘光帆’也许能让我们能达到百分之十左右的光速，这会提供给我们在一个世纪多一点时间内到达鲸鱼座τ星的任务，”格里斯特告诉探索新闻说。

"Fusion prospects of the kind studied by Project Icarus (one of theprojects managed by the non-profit organization IcarusInterstellar) are also anoption, though sails have already been demonstrated in space and are furtheralong in their development."

“伊卡洛斯计划（非营利组织伊卡洛斯星际管理的研究项目之一）的研究核聚变的方法的前景也是一种选择，尽管光帆已被在太空中论证并且在进一步的发展中。”
There's also the possibility of using antimatter to get "maximum bangfor the buck," Gilster points out, but we have yet to develop a means ofgenerating enough antimatter for it to be used as an interstellar fuel. Andthen there's the tricky matter (no pun intended) of storing the stuff andcontrolling the reactions inside a hypothetical antimatter engine.

也有使用反物质以得到“最划算的效果”的可能，格里斯特指出，但我们还没有发展出一种产生足够的反物质用来作为星际航行燃料的手段。然后在一个假设的反物质引擎中存储材料和控制反应是棘手的事（没有双关语意）。

But this is the reason why we should be researching multiple avenues ofresearch when it comes to the possible modes of interstellar travel.

但这就是我们为什么当研究星际旅行的可能模式时要进行多种途径的研究的原因。

ANALYSIS: Alpha Centauri Bb: An Interstellar Target?

分析：半人马座α星：另一个星际航行目标？

"The Tau Zero Foundation hopes to advance the human prospect forinterstellar flight by defining the issues and keeping all the propulsionoptions on the table," Gilster points out. "It is simply too early todown-select to a single propulsion system.

“τ星0基金会希望推进人类星际航行的界定问题并且保持所有摆在桌面上的推进方案的前景，”格里斯特指出。“距离可选择的单一的推进系统出现还太早。

"Instead, incremental advances across the spectrum of possibilitieswill help us, over time, learn which methods will offer the soundest prospects.We'd like to encourage and, when it becomes possible, assist in the funding ofsuch research.

“相反，可选择方法的范围的逐渐扩大将帮助我们，随着时间的推移，获得的这些方法将提供合理的前景。当它成为可能时，我们要鼓励并且资助这种研究。

"A second goal is to keep the idea of interstellar flight in front ofthe public through education, so that the relevant research is not onlyhighlighted but supported through both philanthropy and government."

“第二个目标是把星际航行的观念通过教育呈现在公众面前，以使相关的研究不仅引人注目而且得到慈善机构和政府的支持。”

Going Interstellar By Public Demand

公众关于进行星际航行的询问

The selection of propulsion methods is one thing, but interstellaradvocates agree that when we do detect that bona fide habitable world --with hints of a biosphere and presence of liquid water -- the public willdemand further study.

推进方法的选择是一方面，但是当我们发现真正的可居住的世界（暗示着生物圈和液态水的存在）时星际航行的主张者将获得赞同，公众将会询问的进一步研究。

And that means physically going there.

这意味着要亲自去到那里。

"In the event a habitable planet around a nearby star like Tau Cetiis confirmed, the best next step would be a space-based observatoryspecifically targeting nearby stars (Kepler's targets are much more remote inorder to take the statistical pulse of the planet population)," saidGilster. (Targeted searches have been carried out by SETI, in the hope ofdetecting a radio signal from a hypothetical alien civilization in the Tau Cetisystem -- but none have detected any artificial transmissions.)

“如果一个适合居住的行星围绕的一个附近的恒星像鲸鱼座τ星那样被证实，下一个最好的步骤将是用空间天文台专门对准附近恒星（开普勒望远镜对准更远的地方以便采集统计外星生物的电子脉冲），”格里斯特说。（搜寻地外文明[SETI]的有针对性的搜索已经在进行，以期检测到来自鲸鱼座τ星系的一个假设的外星文明无线电信号——但没有发现任何人工传送的信息。）

"I have often imagined the day when scientists directly image anEarth-like extra-solar planet," Icarus Deputy Project Leader RobertFreeland told Discovery News during an interview in October after the discovery of a small exoplanet orbiting AlphaCentauri (a binary star located only4.4 light-years away). "We would be able to determine the planet'satmosphere and surface temperature from its spectrum, and we would thus knowwhether it might be able to sustain life as we know it.

“我常常想象科学家直接拍摄到太阳系外类地行星的那一天，”伊卡洛斯计划副组长罗伯特·弗里兰在10月份的一次采访中告诉探索新闻记者，在半人马座α星（位于距离我们只有4.4光年远的二等星）的轨道上发现了一颗小型太阳系外行星之后。”我们从光谱上将能够确定行星的大气层和表面温度，那样我们就知道它是否能够维持据我们所知的生命存在的条件。

"I suspect that once such a discovery hits the news, people worldwideare going to demand that we send a probe to determine whether the planethas life (of any type) and/or could be suitable for human habitation,"Freeland added.

“我怀疑一旦这样一个发现出现在新闻上，全世界的人们都将要求我们发送一个探测器确定行星上是否有（任何类型的）生命和/或适合人类居住的可能性，”弗里兰补充说。

SLIDE SHOW: Exquisite Exoplanetary Art

幻灯片显示：精美的地外行星艺术照

"Tau Ceti is about 12 light-years away, and with the rightinstrumentation, we will be able to make a spectroscopic analysis of theatmospheres of planets there," Gilster said. "If we discover abiosignature indicating life is present, this will clearly make such a planet apriority for any future probes. A probe like this could get into space in thenext two decades if funding emerges."

“鲸鱼座τ星大约有12光年远，并且用合适的仪器我们可以对行星的大气进行一个光谱分析，”格里斯特说。“如果我们发现表明生命存在的迹象，这显然会让这样一个行星获得未来的探测器探测一个优先权。像这样可以进入宇宙空间的探测器如果资金充裕在接下来的二十年里将会出现。”

A New Era

一个新的时代

By extrapolating the energy we produce today, Gilster is realistic that aninterstellar probe may be a long way off. But that's not accounting forunforeseen, disruptive technologies that may rapidly enhance our ability ofsending a robotic emissary (and eventually a human mission) to a nearby star.

据我们今天生产的能源推断，格里斯特是现实的，一个星际探测器可能还需要很长的一段路要走。但这并不是不可预见的，爆发性的技术进步可以迅速提高我们派遣一个机器人使者（并且最终人类执行任务）到达附近的一颗恒星的能力，。

We are truly in a new era of space exploration. Not only are wediscovering a multitude of extra-solar planets, we are also advancing the rolethat robotics play in space. It's only a matter of time that these machinesbecome so advanced that they will become fully autonomous -- humans will be cutout of the loop. For a robotic interstellar probe, this will be a necessity asthe vast interstellar distances will quickly generate unworkable time lags ofyears to send and receive commands.

我们确实处于太空探索的新纪元。我们不仅发现了大量的太阳系外行星，我们也正在提高机器人在太空遨游的作用。这只是一个时间问题，这些机器变得如此先进以至于他们将成为完全自主的——人类将被从圈子中取代。一个机器人星际探测器，这将是很有必要的，因为在浩瀚的星际距离中发送和接收命令是行不通的很快就会产生长达数年的延迟时间。

The speed of light will quickly become a frustrating barrier (after all,should a probe make it to Tau Ceti, it would take 12 years for us to receivethe first images of any "habitable" exoplanet), the probe would be byitself, exploring in the name of humanity.

光速会很快成为一个令人沮丧的障碍（毕竟，该探测器将被发送到鲸鱼座τ星，12年后它会让我们来接收“可居住的”太阳系外行星的第一幅图像），探测器本身将以人类的名义进行探索。

But like any interstellar concept, it's a question of energy production.Until we find a way of overcoming this challenge, we will be foreverquarantined from the promising planets orbiting neighboring stars, depending onincreasingly powerful telescopes to peek into their atmospheres, frustratedthat we can't see them up-close.

但像一切星际航行概念一样，能源生产是一个问题。直到我们找到方法克服这一挑战，我们将永远被隔离在环绕邻近的恒星运行的行星的前途之外，只能指望日益强大的望远镜窥视他们的大气，我们不能近距离看到他们将是非常沮丧的。

But with the ongoing efforts of organizations such as the TauZero Foundation, IcarusInterstellar and the 100Year Star Ship Project, the sciencebehind interstellar travel will remain in the public mindset, hopefullyfacilitating mankind's push into the expanse between the stars while motivatingexploration within the solar system.

但随着τ星0基金会，伊卡洛斯星际和百年星舰计划等组织的不断努力，星际旅行背后的科学，将存留于公众的心中，有希望促进人类向广阔恒星之间进发，从而激励太阳系内的探索。

Scientists agree that Pion antimatter powered spacecraftmay approach the speed of light.The late Dr. Robert Carroll, a mathematical physicist whorejected relativity, claimed a Pion powered spacecraft might approach 20million times the speed of light. See pages 34-37 at CHEAP GREEN on www.aesopinstitute.orgMuon - Pion fusion is under development in Australia andalso by a Japanese - British Joint Venture.If successful, spacecraft will surely be powered by Piondrives.A test craft that might prove Dr. Carroll correct,andaccelerate well beyond the speed of light, would open human exploration ofGoldilocks planets.

科学家认为，介子反物质动力飞船可能接近光的速度。
已故的罗伯特·卡罗尔博士，一个拒绝相对论的数学物理学家，声称一艘介子动力飞船也许可以达到接近光速的20000000倍。参见位于www.aesopinstitute.org《廉价的绿色》第34 - 37 页
介子核聚变也正在由日本-英国合资在澳大利亚发展。
如果成功，航天器将由介子驱动。
技术测试可以证明卡罗尔博士是正确的，它应该可以加速超越光的速度，将开启人类探索金发行星的大门。

Actually, the theory states that the closer an objectgets to light speed, the greater it's mass. It's hard enough trying to power aship (or probe) normally, but what happens as it gains mass? Eventually, therewouldn't be enough energy in the universe to power something with nearlyinfinite mass. It would probably collapse into a singularity long before that,however.

实际上，该理论指出，一个物体越接近光速，它的质量越大。启动飞船（或探测器）一般是很困难的，但它质量增加的时候会发生什么？最终，在宇宙没有足够的能量启动几乎无限的质量的物体。然而，在那之前很久它可能会落入一个奇点。

I'm more than a little skeptical of Horvath's Australianproject. He's claiming to have a 1-megawatt nuclear fusion device with 99%energy efficiency... and it's smaller than my microwave oven. He has nopublished papers and no demonstratable prototype -- but he's more than happy toaccept investors! My Scam-O-Meter gets all twitchy with this one.As far as Carroll goes, his patent application was rejectedin 1971. Forty years later, I still see no Pion hyperspeed drives on ourpan-galactic starships, no pollution-free nuclear reactor in my fridge, noantigrav drive in my car, and no matter teleporter in my foyer. There's areason for that -- it starts with "real" and ends with"ity."

我非常怀疑霍瓦特的澳大利亚项目。他声称自己有99%的能源效率的1兆瓦的核聚变装置…并且比我的微波炉还小。他没有发表的论文而且没有示范的原型——但他更乐意接受投资者！我的Scam-O-Meter得到所有焦虑都来自于此。据卡罗尔说，1971年他的专利申请被拒绝。四十年后，我仍然没有在我们的泛银河系飞船上看到介子高速驱动，我的冰箱里没有无污染的核反应堆，我的汽车里没有反重力装置，并且在我的门厅没有传送门。原因就是——它开始得“真实”，结束得“干净”。

I'm not much for doomsday predictions, but eventually theodds are going to stack against the planet. If we don't reach out to the stars,we, as a species, may die out, having left nothing but relics for an alienarcheologist to discover. As things stand now, we still have all the eggs inone basket, and something as simple as an asteroid impact could spell the end.

There will always be projects on Earth that people canpoint to, for throwing money at. No matter how many of those you do, there arealways more, and people who say that those projects should be first. Butfinding other life (other intelligent life, perhaps, with all the ramificationsof such), or just having other worlds to live on, so a single catastrophe can'twipe us all out - these are things you cannot put a price on. Either such eventwould be incalculable in its long-term affect on mankind. They make this orthat social program insignificant in comparison.

总是会有人提出项目在上面扔钱。不管你做多少，总有更多的人说这些项目应该是第一位的。但寻找其他生命（其他智能生命，也许，包括在一切这样的结果中），或有没有其他的世界可以生存，因为单独的大灾难不会消灭我们全部——这些不是你能漫天要价的事情。当然这样的事件会对人类造成不可估量的长期影响。但这些与这样或那样的社会计划比起来微不足道。

Any advancements in aerospace technology havealways had huge effects on civilization as a whole. New ways of space travelwill also lead to new methods of land and air travel that could significantlyimprove every day life as we know it.

No dilithium crystals? Seriously, though, I assume wewould need more information before we embark on a mission that, at 10% of c,will still require about 130 years to report.

About SETI, let's be frank: we will not contact othercivilizations (perhaps ever) not because they aren't there, but because theyare far too advanced to care much about us. In a galaxy that is 13 billionyears old, there is a good chance that a random other civilization could easilybe millions of years more advanced than we are. They would see us the way wesee Proconsul (if alive today), an oddity but not worth communicating with.They would have technology that would allow them to communicate in a fashion(ie a code) that would look like white noise to us (the closer to white noise amessage seems to be, the better the code and their codes would be exceptionallyopaque); or they might use sub-space or worm-holes, which our descendents mightnot discover for a million years. They would view us probably as we viewearthworms, harmless but not very interesting. Perhaps they function at adifferent level of consciousness, in fact perhaps several levels ahead of us...a state we have no way of even sensing, understanding or studying. Our currentapproaches assume we'll find a civilization very close to us in age/development-- highly unlikely -- and, so, our efforts probably represent more of a roadmapfor us into the future .

关于地外文明探索，坦率的说：我们接触不到其他文明（也许）不是因为他们不存在，而是因为他们太先进以至于不关心我们。在一个130亿岁的星系，一个随机的其他文明很可能是比我们更先进数百万年是很有可能的。他们会看我们就像我们看殖民地总督（如果今天还活着的话）一样，古怪但不值得与之沟通。他们有技术，让他们以一种方式（比如代码），在我们看来像毫无规律的噪声（以越近乎毫无规律的噪声传递消息越是好的代码，他们的代码是非常不透明的）；或者利用子空间或虫洞这些我们的后代可能一百万年都发现不了的手段。他们看我们可能就像我们看蚯蚓，无害但不是很有趣。也许他们的意识功能与我们在不同水平，也许在我们前面的几个层次…一种甚至连感知、理解和学习都没有办法的规则。我们目前的做法是假设我们会找到一个非常接近我们的年龄/发展的文明——极不可能——而且，所以，我们的努力可能只代表我们走向未来的路线图。
