That means less time the rocket is required to burn, lower temperatures scorching the outside of the spacecraft, less force and compression ripping at the spacecraft, and generally fewer opportunities for something to go very wrong.</p><p><blockquote>亚轨道飞行需要的功率和速度要小得多。这意味着火箭燃烧所需的时间更少，烧焦航天器外部的温度更低，航天器上的力和压缩撕裂更少，并且通常出现严重问题的机会更少。</blockquote></p><p> New Shepard's suborbital fights hit about about three times the speed of sound — roughly 2,300 miles per hour — and fly directly upward until the rocket expends most of its fuel. The crew capsule will then separate from the rocket at the top of the trajectory and briefly continue upward before the capsule almost hovers at the top of its flight path, giving the passengers a few minutes of weightlessness. It works sort of like an extended version of the weightlessness you experience when you reach the peak of a roller coaster hill, just before gravity brings your cart — or, in Bezos' case, your space capsule -- screaming back down toward the ground.</p><p><blockquote>新谢泼德的亚轨道战斗达到了大约三倍音速——大约每小时2300英里——并直接向上飞行，直到火箭耗尽大部分燃料。然后，乘员舱将在轨道顶部与火箭分离，并在太空舱几乎悬停在其飞行路径顶部之前短暂继续向上，为乘客提供几分钟的失重状态。它的工作原理有点像当你到达过山车山顶时所经历的失重的扩展版本，就在重力将你的手推车——或者在贝佐斯的情况下，你的太空舱——带着尖叫回到地面之前。</blockquote></p><p> <img src=\"https://static.tigerbbs.com/1aeef7cd6efed45b4f08991c7c4b7be4\" tg-width=\"780\" tg-height=\"438\"></p><p><blockquote></blockquote></p><p> The New Shepard capsule then deploys a large plume of parachutes to slow its descent to less than 20 miles per hour before it hits the ground.</p><p><blockquote>然后，新谢泼德太空舱部署大量降落伞，在落地前将其下降速度减慢到每小时20英里以下。</blockquote></p><p> The rocket, flying separately, re-ignites its engines and uses its on-board computers to execute a pinpoint, upright landing.

With an orbital re-entry, a spacecraft's external temperatures can reach up to 3,500 degrees Fahrenheit, and astronauts can experience 4.5 Gs of force that is also placed upon the spacecraft, all while the ever-thickening atmosphere whips around the capsule.</p><p><blockquote>因为亚轨道飞行不需要那么高的速度，也不需要试图以令人难以置信的速度重返地球大气层的紧张过程，所以它们被认为比轨道飞行风险小得多。随着轨道重返，航天器的外部温度可以达到3500华氏度，宇航员可以承受4.5克的力，这种力也施加在航天器上，同时不断变厚的大气在太空舱周围跳动。</blockquote></p><p></p><p> High speeds and high altitudes come with inherent risks, and even small errors can have big consequences. Earth's atmosphere is generally not considered survivable for significant amounts of time above altitudes of 50,000 feet without a spacesuit, and Bezos will be traveling up to 350,000 feet. But the capsule he travels in will be pressurized, so he doesn't need a special suit to keep him safe, and he'll have access to an oxygen mask if the cabin loses pressure. The spacecraft is also equipped with an abort system designed to jettison the New Shepard capsule and passengers away from the rocket in case of emergency. There's also back-up safety features to help the capsule land gently even if a couple of its parachutes fail to deploy.</p><p><blockquote>高速和高海拔伴随着固有的风险，即使是很小的错误也会产生很大的后果。如果没有宇航服，地球大气层通常被认为无法在50,000英尺以上的高度生存很长时间，贝佐斯将旅行到350,000英尺。但是他乘坐的太空舱将被加压，所以他不需要特殊的宇航服来保证他的安全，如果机舱失去压力，他可以使用氧气面罩。该航天器还配备了一个中止系统，旨在在紧急情况下将新谢泼德太空舱和乘客抛离火箭。还有备用安全功能，即使几个降落伞未能展开，也可以帮助太空舱平稳着陆。</blockquote></p><p> But even still, there is no way to absolutely guarantee safety should New Shepard malfunction.</p><p><blockquote>但即便如此，如果新谢泼德出现故障，也没有办法绝对保证安全。</blockquote></p><p> Even though suborbital flights are less risky than orbital missions, they can still be deadly.</p><p><blockquote>尽管亚轨道飞行的风险低于轨道任务，但它们仍然可能是致命的。</blockquote></p><p> One of Virgin Galactic's suborbital space planes, for example, broke apart in 2014 when one of the vehicle's copilots prematurely deployed the feathering system designed to keep the craft stable as it made its descent.

With an orbital re-entry, a spacecraft's external temperatures can reach up to 3,500 degrees Fahrenheit, and astronauts can experience 4.5 Gs of force that is also placed upon the spacecraft, all while the ever-thickening atmosphere whips around the capsule.\nHigh speeds and high altitudes come with inherent risks, and even small errors can have big consequences. Earth's atmosphere is generally not considered survivable for significant amounts of time above altitudes of 50,000 feet without a spacesuit, and Bezos will be traveling up to 350,000 feet. But the capsule he travels in will be pressurized, so he doesn't need a special suit to keep him safe, and he'll have access to an oxygen mask if the cabin loses pressure. The spacecraft is also equipped with an abort system designed to jettison the New Shepard capsule and passengers away from the rocket in case of emergency. There's also back-up safety features to help the capsule land gently even if a couple of its parachutes fail to deploy.\nBut even still, there is no way to absolutely guarantee safety should New Shepard malfunction.\nEven though suborbital flights are less risky than orbital missions, they can still be deadly.\nOne of Virgin Galactic's suborbital space planes, for example, broke apart in 2014 when one of the vehicle's copilots prematurely deployed the feathering system designed to keep the craft stable as it made its descent. The added drag on the plane ripped it to pieces, killing one of the pilots.\n(Blue Origin competitor Virgin Galactic has since had three successful test flights of a revamped version of its SpaceShipTwo space plane.)\nBlue Origin has not encountered similar tragic accidents during its testing phase, though — as an old industry adage goes — space is hard.\nBut, Bezos has indicated, the risk is worth it.","news_type":1,"symbols_score_info":{"AMZN":0.9}},"isVote":1,"tweetType":1,"viewCount":1223,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":186804801,"gmtCreate":1623482247503,"gmtModify":1634032509637,"author":{"id":"3576031533816126","authorId":"3576031533816126","name":"kukuniao","avatar":"https://static.tigerbbs.com/e2bcc0cf2ff759243bcb5c9d5662d212","crmLevel":12,"crmLevelSwitch":0,"followedFlag":false,"idStr":"3576031533816126","authorIdStr":"3576031533816126"},"themes":[],"htmlText":"Not
