Tesla is just foreplay, Thomas g released "Dragon" ship II-Dragon V2.SpaceX Dragon spacecraft-IT news Tesla is just foreplay, Thomas g released "Dragon" second generation ship
United States SpaceX Corporation today released the second generation of Dragon spacecraft (Dragon V2), which was the first manned spacecraft launched by a private company, can transport a maximum of 7 astronauts to the international space station, according to NASA and SpaceX plans, Dragon 2 in 2017 is expected to fly to space.
SpaceX co-founder Yilong·masike (IT news Note: Marske and Tesla CEO) introduced, it can return to Earth and be "precisely like a helicopter landing on any surface, and it can be quickly reused. You only need an injection of new propellants, and then you can come back at a time ... ... Imagine if after the end of each mission, spacecraft are discarded, and no one can bear the cost of such flights. ”
Prior to this, SpaceX has already shown the first Dragon spacecraft (Dragon V1), the smaller and cannot be manned, mainly used for testing, and the few times the delivery of cargo to the international space station mission. Second generation Dragon ships is an improvement on the heat shield, astronauts return through the atmosphere can provide better protection.
Dragon 2 manned spacecraft SuperDraco propeller and is formed by 3D printing, this is the first use of 3D printing ship's engines. Elon said that when designing the first generation when the Dragon spacecraft, they also don't have a lot of ideas. Second generation of Dragon spacecraft will be capable of carrying seven people, as well as helicopters, relies on precision landing in any of the propeller.
Similar to the first generation of unmanned Dragon, Dragon V2 also uses the Falcon 9 rocket to launch and obtain energy through solar panels. Dragon V2 is equipped with a parachute, landing from the surface. Integrated launch abort engine in the crew cabin, SuperDraco propeller, launching an emergency escape system to use when.
Dragon V2 also integrates a docking system that is installed on the front, allowing docking to the international space station. Cargo space is located in the rear section of the ship. This is an unconfined area, can accommodate a maximum of 490 trillion cubic feet (14 m) of goods.
Future commitment of NASA's manned missions
The unveiled the second generation Dragon spacecraft marked manned a new chapter in the history of mankind: in 2011, after a retired space shuttle fleet as a whole, SpaceX and two other companies – Boeing and Sierra Nevada Corporation (Sierra Nevad)--from the United States won more than $ 1 billion in orders at the Agency for the development of "sky bus" system, tasks for future implementation of transporting astronauts to the international space station.
Worth noting is that this is decades of United States to build the first manned spacecraft, and Americans can claim to be ordinary people into space has been opened up in the commercial sector. From a certain perspective, it is a matter of United States national dignity, a great event. At present, the United States is almost completely dependent on Russia's Soyuz spacecraft will be sending astronauts to the international space station. United States to reach other planets (or ISS) exist only in fantasy in other countries.
At the time of the end of April, it has become clear. Russia Deputy Prime Minister miteli·luogejin on United States sanctions back at that Americans might consider a "trampoline" to astronauts on the international space station. Just a few hours later, Yilong·masike declared, will be launching a manned spacecraft at the end of May.
United States NASA hopes this "space bus" system put into operation around 2017 to 2018. Currently unmanned version of the first generation of Dragon spacecraft have been used to transport cargo to the ISS, the recent transport tasks has just completed this month. However the United States NASA still wants the company to accelerate the upgrade in order to begin manned space flights as early as possible, and hopes NASA manned version of Dragon spacecraft to have a response mechanism, when if a failure occurred during launch or the rising phase of the crew has the escape option.
Second generation spacecraft Dragon the Dragon V2 will probably change our "ship" awareness. The curtain will soon unveil, the secret is revealed, all to be seen.
特斯拉只是前戏，马斯克发布“龙”飞船二代 - Dragon V2.SpaceX,龙飞船 - IT资讯特斯拉只是前戏，马斯克发布“龙”飞船二代
美国SpaceX公司今日发布第二代龙飞船（Dragon V2），这是首个由私营公司推出的载人飞船，一次最多可运送7名宇航员前往国际空间站，根据NASA和SpaceX的规划，龙2有望在2017年正式飞往太空。
据SpaceX合作创始人伊隆·马斯克（IT资讯注：马斯克同时也是特斯拉CEO）介绍，它可以返回地球并能“像直升飞机一样精确地降落在任何地面，并且它可以快速地重复使用。你只需要重新注入推进剂，然后就可以再来一次……想象下如果每次任务结束之后，航天飞船都被丢弃的话，没人可以承担这样的飞行成本。”
在此之前，SpaceX已经展示了第一代龙飞船（Dragon V1），其体积更小，而且不能载人，主要用于测试，并进行了为数不多的几次运送货物前往国际空间站的任务。第二代龙飞船在热屏蔽上有所改进，在宇航员返程穿过大气层时能更好地提供保护。
龙2载人飞船的SuperDraco推进器由3D打印而成，这是首款投入使用的3D打印飞船引擎。伊隆说，当设计第一代龙飞船时，他们还没有太多的想法。第二代龙飞船将能够运载七个人，并能像直升飞机一样，依靠推进器精准地降落在任何地面。
与不载人的第一代Dragon类似，Dragon V2也将使用Falcon 9火箭来发射，并通过太阳能面板获得能源。Dragon V2配备了降落伞，能从水面着陆。乘员舱中集成了发射中止引擎，即SuperDraco推进器，在发射出现紧急情况时作为逃生系统来使用。
Dragon V2还集成了前部安装的停靠系统，从而可以对接国际空间站。运货空间位于飞船尾部。这是一个非承压的区域，能容纳最多490立方英尺（14立方米）的货物。
未来承担美宇航局载人任务
此次揭开神秘面纱的第二代龙飞船标志着人类载人航天历史上的一个崭新篇章：自从2011年航天飞机机队整体退役之后，SpaceX和另外两家公司——波音以及内华达山脉公司(Sierra Nevad)——从美国宇航局获得超过10亿美元的订单用于开发“天地巴士”体系，用于未来执行向国际空间站输送宇航员的任务。
值得注意的是，这是几十年来美国建造的第一艘载人宇宙飞船，而美国人也可以宣称自己开辟了将普通人送往太空的商业领域。从某个角度上，这是事关美国国家尊严的一件大事。目前，美国几乎完全依靠俄罗斯的联盟号飞船将宇航员送上国际空间站。美国到达其他星球(或国际空间站)的能力只存在于其他国家的幻想之中。
在四月底的时候，这一切已经趋于明朗。俄罗斯副总理米特里·罗戈津针对美国的制裁反击道，美国人可以考虑用“蹦床”将宇航员送到国际空间站。就在几小时之后，伊隆·马斯克就公开宣布，将在五月底时发布一款载人宇宙飞船。
美国宇航局希望这种“太空巴士”体系从2017年至2018年左右开始投入运行。目前不载人版的第一代龙飞船已经被用于向国际空间站运输货物，最近的一次运输任务于本月刚刚执行完毕。然而美国宇航局仍然希望该公司加速进行升级以便尽早开始执行载人航天飞行，并且NASA还希望载人版的龙飞船能拥有应急机制，当在发射或上升阶段发生故障时乘员组拥有逃生的选项。
第二代龙飞船Dragon V2或许将会改变我们对“飞船”的认识。大幕很快就将揭开，秘密即将揭晓，一切拭目以待。
