SpaceX test flight of cargo craft a success
KENNEDY SPACE CENTER, FL--A commercially developed rocket critical to the long-term health of the International Space Station blasted off today on a long-awaited test flight, boosting an untried cargo craft into orbit for a successful maiden flight, which the company's founder described as "mind-blowingly awesome."
SpaceX's Falcon 9 rocket, carrying a new space station cargo delivery module, blasts off from the Cape Canaveral Air Force Station on the first of three planned NASA-sponsored test flights.
(Credit: Spaceflight Now/Justin Ray) Operating autonomously, the Dragon carried out a pre-planned set of maneuvers during two orbits to mimic critical phases of a rendezvous with the International Space Station and to exercise its 18 thrusters, its power system, and its navigation and control equipment and software.
It then carried out a de-orbit rocket firing and plunged back into the atmosphere, making a pinpoint landing in the Pacific Ocean some 500 miles west of Baja California just after 2 p.m. EST .
Company officials said the capsule achieved all of its planned objectives, becoming the first commercially built spacecraft to be launched into orbit and safely returned to Earth.
"This has really been better than I expected," said SpaceX founder Elon Musk, the CEO and chief technology officer. "Just looking at all the mission data, both real-time and what's come back from the stored telemetry, it's actually almost too good. I shouldn't seem surprised by that!"
The nozzle of the Falcon 9's second stage engine glows with the heat of combustion as the rocket climbs toward space.
(Credit: SpaceX) The flight was the first of three financed by NASA under a $278 million Commercial Orbital Transportation Services (COTS) contract, the centerpiece of a program designed to encourage development of private-sector rockets to deliver cargo to the International Space Station after the space shuttle is retired next year.
Based on the results of the first test flight, Musk said he plans to lobby NASA to combine elements of the second and third missions and to send the next Dragon directly to the International Space Station next summer.
NASA Administrator Charles Bolden told CBS News he would rely on agency engineers and managers in the COTS program to make that assessment, saying "what our folks have to do is sit down, take a look at results from this test, and see how do we interpret what we see and how do we transfer that into comfort that a different-configured vehicle" will perform as required.
But Musk said he is confident Dragon will be up to the task. Looking further down the road, he said the Dragon capsule can easily be modified to carry astronauts to and from the space station within two or three years and that with a superior heat shield, it will rival or exceed the capabilities planned for NASA's deep-space Orion capsule.
"People sometimes think that to take a cargo spacecraft and put a crew into it requires this enormous amount of magical pixie dust or something," he said. "This is not at all the case. If there had been people sitting in the Dragon capsule today they would have had a very nice ride. They would have experienced maybe up to four and a half Gs, about what you'd see in an amusement park, and they would have done quite well."
But the clear focus of near-term development is perfecting the Dragon cargo capsule and beginning space station deliveries next year, a critical milestone as NASA transitions to the post-shuttle era, relying on a variety of cargo craft to deliver the supplies needed to support a full-time crew of six.

(Credit: SpaceX) Capable of carrying 13,200 pounds of cargo in pressurized and unpressurized cargo bays, the Dragon spacecraft can deliver more than twice the load of supplies carried by Russian Progress cargo ships.
SpaceX hopes to begin actual cargo delivery flights next November under a 12-flight $1.6 billion Commercial Resupply Services contract with NASA that calls for the delivery of 44,000 pounds of equipment and supplies to the International Space Station. NASA hopes to operate the station through at least 2020 and SpaceX may be asked to provide additional missions, boosting the contract's value up to $3.1 billion.
"From all indications, it looks like it was 100 percent successful and it was just a great experience and wonderful to watch," said Alan Lindenmoyer, manager of the commercial crew and cargo program at the Johnson Space Center in Houston. "We're certainly looking forward to our next demonstration flight and taking the next step closer to space station. Thank you for the early Christmas present. What a great way to start the holidays."

(Credit: SpaceX) Running a day late because of work to cut away a cracked section of the rocket's second-stage engine nozzle, the Falcon 9's nine first-stage Merlin engines roared to life at 10:43 a.m. and quickly throttled up to full thrust. After a final round of lightning-quick computer checks, hold down clamps released, and the 157-foot-tall rocket majestically climbed away from launch complex 40 at the Cape Canaveral Air Force Station.
The early moments of the flight appeared flawless as the white booster streaked away to the east through a cloudless blue sky trailing a brilliant jet of flame and a billowing cloud of exhaust.
The first-stage engines shut down as planned just under three minutes into flight, the stage fell away and the single engine in the second stage ignited for a planned six-minute boost to orbit. Television views from a camera mounted at the base of the second stage showed first-stage separation and the ignition of the second-stage engine, its nozzle glowing cherry red from the heat of combustion.
The second stage appeared to fire normally, shutting down nine minutes after liftoff. About 35 seconds later, the Dragon cargo craft could be seen in another "rocket cam" video feed separating from the second stage, released into a slightly elliptical 186-mile-high orbit tilted 34 degrees to the equator.
Musk said the spacecraft performed a variety of maneuvers to demonstrate the guidance and propulsion systems' ability to rendezvous with the International Space Station.
"The maneuvers that were conducted were very similar to the sort of maneuvers we would conduct when going to the space station," Musk said. "There's no meaningful difference in complexity."
All of the systems worked normally, he said. Following the deorbit rocket firing, the Dragon capsule reoriented itself, heatshield first, and plunged back into the atmosphere with a 12-degree angle of attack. Drogue parachutes deployed on time, followed by release of three huge orange-and-white parachutes.
The spacecraft, the first privately built vehicle to win an FAA license for re-entry and landing, made a pinpoint splashdown within sight of recovery forces.
The ability to recover Dragon is a key selling point because it will allow NASA to bring back failed components, trash, and, most important, experiment samples that cannot otherwise be returned to Earth with existing Russian, European, and Japanese cargo ships.
"It was definitely a moment of elation and great relief," Musk said of the splashdown. "Drogue deploy and main chute deploy were the riskiest points in the mission. So when those main chutes came out, it was a done deal. It's just mind-blowingly awesome."

那啥，其实低轨道太空旅游也非常不错了，俄罗斯联盟就只能载3人，搭载了一个太空游客就是2500万美金，如果是6人飞船，搭载3个游客，整个飞船的成本都负担出去了，再如果是小飞机呢，倒时候赚了钱就能更好的服务火星基地项目了不是。
未来美国的中等推力火箭主要靠spaceX和轨道科学两家公司了，波音和洛马主抓EELV重型通用火箭。
呵呵，正好和公司规模相匹配。spaceX雇员700，轨道科学也仅三千，中小型公司。

航海、航空市场已经被私人公司主导了，尽管这两个领域都涉及“国防”。航天市场这是早晚的事。
spaceX这类公司已经不是第一批了，十年前就曾经出现过很多民间私营公司，开发过“罗顿”等新概念火箭，不过这最初的一批基本没进入实施阶段就倒掉了。现在的spaceX也好，维珍也好，实际上都是后继者了。

轨道科学公司的主营业务之一——通讯卫星——是没什么政府订单的。它将其卫星市场定位在中低端客户上，拉开与劳拉、波音等巨头的档次。貌似生产过50多颗了~
很多产业的起步都是靠政府的，例如互联网、电脑等等。当市场做大、成熟后，自然会逐渐改变。
当然，对于宇航业，这个市场有多大还不好说，但确实已经涌现出了轨道科学、geoeye、全球星这样的公司。

对不起，让你失望了，到目前为止，SPACEX的产品的所有部件的研制，开发，生产，装配，发射，租用发射场地等等一切费用都是SPACEX独自承担，至于你说的NASA订单资金等等都不是今年的事，钱还没拨出来呢，人员更不关NASA的事，都是公司内部员工,美国政府到目前为止对公司最大的支持不过是政策上的，不过考虑到其政策的一贯性，而SPACEX也不是第一家搞私人航空的企业，而之前的企业都死在创业初期（而且基本上搞的都没有SPACEX这么大，这么全），所以说这次的成功当然值得大书特书，这不是技术上的胜利，而是管理，商业上的胜利，是技术和管理的完美结合，开创了一个时代的先河

最后转一个航天航空港cmj9808老大的总结：
Falcon 9：
虽然喷口截去了一节，但F9表现得很好，从起飞到Dragon分离的过程非常顺利，第一次发射时上面级滚转的问题得到了解决，次级载荷成功分离后上面级进行了二次点火，将远地点提升至11000km，模拟了一次准GTO任务。
Dragon：
验证了除太阳能板和辐射散热器外的所有系统，包括通讯导航、电力、推进以及热防护和回收系统，所有系统均实现或超过了预期目标。18个Draco和3个主伞（其中2个是备份，Dragon靠1个主伞即可安全降落）均工作良好，着陆入水速度8 m/s，精度800m，再入过程最大过载4.5g，PICA-X热护盾的余量留的太多，今后可能会减少一层以减重。另外有消息说Dragon在轨进行了与ISS模拟对接的机动，所以COTS2与3合并的可能性增加。另外，Dragon里搭载了一个特殊货物，但Musk要等到明天才肯说是什么，从Musk很渴望商业载人这一点看，很可能是小动物。
次级载荷：
友情搭载了来自DoD的载荷，从logo上看有来自陆军、海军研究实验室和洛斯阿拉莫斯的cubesat，几个载荷均顺利释放并与地面通讯，目前状态良好。DoD省了钱，SpaceX也证明了F9的商业搭载能力，双方皆大欢喜。
美中不足之处：
1，发射时上面级的燃料加注脐带被火箭的尾焰点着了，可能是阀门没关好。
2，助推级仍然未能完整回收，不过这次成功接收到遥测信号，表明这次没有空中解体，距离完整回收又前进了一步。
总的来说，这次任务非常成功，Musk之前预测任务成功的概率是66%，对于SpaceX的很多人来说，今晚又将是另一个不眠之夜。
Big congrats to SpaceX and NASA！Nice work！
以NASA局长Bolden的贺词作为结束，他将这次发射比作林白的横跨美国之旅，那次历史性的飞行开辟了商业航空之路，其中的寓意不言自明。

美國民間太空船「飛龍號」 (Dragon)8日進行處女航試飛，成功發射到太空軌道環繞地球飛行兩周，順利完成三小時航程降落在太平洋海面，為商業太空旅行及首座商業太空站舖路。
太空探索科技公司 (Space Explorations Technologies Corp Inc.，簡稱SpaceX)完成歷史性創舉，8日上午在佛州卡納維爾角發射「獵鷹九號」 (Falcon 9)火箭，載著「飛龍號」升空。飛龍號發射九分鐘後即進入軌道，繞地球飛行兩圈後返回地球，靠降落傘落在墨西哥外海約805公里處，距預定地點只有10公里，時間也只比預定慢52秒。收回人員迅速抵達現場。
NASA太空梭明年退休將聘民營企業
因預算緊縮，NASA明年將讓太空梭機隊退休，未來將聘用太空探索科技公司等民營企業載運補給到國際太空站，最後更希望它們載送太空人。太空梭只剩明年2月、4月兩次任務，NASA正設法爭取經費進行更多次飛行
SpaceX達國家級水準
獲NASA合約
飛龍號高5.18公尺、直徑3.6公尺，預定還要試飛兩次，準備明年11月載運貨物上太空。SpaceX獲NASA價值16億美元的合約，必須提供12趟補給服務。下一代飛龍號將配備腳架，可在直升機坪大小的區塊進行精準降落。SpaceX員工僅1200人，卻能達到國家級太空機構的技術水準。
