SpaceX公司Dragon载人飞船，已经创造历史。细节体现差距 ...

不过这个塔台，真的是艺高人胆大，简洁高效啊。

民营企业的崛起吧，

感慨龙飞船的太阳能板整流罩和飞船外部简洁的设计  如果给它罩一个一体式的大整流罩 估计他的运载能力也得降低不少吧

龙船啊?

不是龙舟啊？

发射机太寒碜了。
宇航员不是自己爬梯子爬上去吧？

就这点高度，如果有需要，CAT表示做一个人员提升机没有任何压力，三一也能做。

昨天的Flight Readiness Review终于开绿灯了，现在NASA已经没有问题了，明天SpaceX自己还有一个Launch Readiness Review，一切顺利的话有望19日发射

目前这东西也就运运货吧，到运人应该还需要一段时间？

MD又走在前头了,希望私企的活力能为航天带来些变化,拭目以待吧,兔子也要加油了

看看这两天会不会射

要是因为非天气原因再延期的话, 未免有点太丢脸了吧

spaceX非要搞陆地着陆，载人版和货运版相比变化不小，离能运人还早着呢

California's SpaceX company is ready to make history by sending a capsule containing half a tonne of supplies to the space station.

It will be the first time the private sector has provided such a service.

The task is usually performed by the vehicles belonging to government space agencies, such as Nasa and Esa.

The unmanned Dragon cargo ship is due to launch atop SpaceX's own Falcon 9 rocket from Cape Canaveral Air Force Station in Florida.

Controllers are targeting a time of 04:55 EDT (08:55 GMT; 09:55 BST), and despite some storms in the area in recent days, the mission team should get favourable weather conditions.

"There's no question - this is a historic flight," said SpaceX president Gwynne Shotwell on the eve of the mission.

"They've been only four nations, or groups of nations, that have berthed or docked a spacecraft to the International Space Station: Europe, Russia, the United States of course, and Japan. So, we really stand in awe at having the opportunity to attempt this."

Although billed as a demonstration, the mission has major significance because it marks a major change in the way the US government wants to conduct some of its human spaceflight operations.

Both SpaceX and another private firm, Orbital Sciences Corp, have been given billion-dollar contracts to keep the space station stocked with food and equipment. Orbital hopes to make its first visit to the manned outpost with its Antares rocket and Cygnus capsule system later this year.

The new approach is intended to free the US space agency to concentrate more of its effort and funds on planning exploration missions far beyond Earth, to asteroids and Mars.


"We feel like it's time and required for us to turn over cargo delivery to the International Space Station (ISS) to the private sector, being more cost effective and enabling Nasa to take our savings and plough them into those other things we're going to be continuing to do in the years ahead," explained Phil McAlister, the acting director of the agency's commercial spaceflight development programme.

The powered ascent of SpaceX's Falcon rocket should last a little under 10 minutes, with the Dragon capsule being ejected just over 300km (185 miles) above the Earth.

The conical spaceship will then deploy its solar panels and check out its guidance and navigation systems before firing its thrusters to chase down the station.

If practice manoeuvres go well over the next couple of days, the plan is try to attach Dragon to the space station on Tuesday.

Unlike the Russian and European robotic freighters that drive all the way into docking ports on ISS, Dragon will move itself to a position just 10m under the platform where it will be grabbed by a robotic arm operated by astronauts inside the orbiting laboratory.


Dragon will be attached and released from the underside of the station by a robotic arm
The arm will berth Dragon to the "Harmony" connecting module on the ISS. The crew are then expected to start unloading the ship's supplies of food and other consumables on Wednesday.

"This is a test flight," cautioned Ms Shotwell. "What's important from a SpaceX perspective on a test flight is to make sure we learn something.

"Hopefully, we learn a lot; and, hopefully, we make a lot of progress. But really what we're here to do is to demonstrate this spacecraft, wring it out to the maximum extent possible, and then obviously the ultimate goal is to berth."

This mission is part of Nasa's Commercial Orbital Transportation Services (Cots) programme which was established to help shift some of the agency's traditional roles and activities into the private sector.


Dragon has already practised coming back from orbit following a short flight in 2010
Nasa is providing seed funding of approximately $800m (￡500m) to SpaceX and Orbital to assist them in the development of their rocket and capsule systems. Once they have reached the milestones laid out under Cots, the full ISS re-supply contracts will kick in.

For SpaceX, this is valued at $1.6bn (￡1bn) and calls for a minimum of 12 Dragon missions to the ISS.

But the company also has a desire to ferry crews back and forth to the station.

To that end, its capsule has been designed from the outset to carry people; and under another Nasa programme, the company is working to develop the onboard life-support and safety systems that would make manned Dragon flights feasible.

Since the shuttles were retired last year, America has no means currently of launching its own astronauts into space - rides must be bought for them on Russian Soyuz rockets at more than $60m (￡40m) per seat. SpaceX says Dragon could be ready to carry people in 2015 at a seat price of $20m (￡15m).

"In order for Nasa to be able to afford any programme of exploration in the future given the fiscal realities of the government, it has to transition away from high-cost services that are procured by and for the government into shared-use services that are competitively sourced," observed Jeff Greason, the president of XCOR Aerospace and a leading proponent of commercial space activity.

人家的成就要正视。不自卑，不妒忌，继续努力，才能赶上。总有一天，土鳖的民企也能发射火箭。

希望SpaceX发射成功，开创人类航天的新纪元。

希望SpaceX发射成功，这个确实是里程碑式的事件，虽说有nasa的支持，不过一个成立10年的私人公司，能做到这一点，也非常不容易。

SpaceX的成功同样是基于NASA多年的积累之上的。

这你就搞错了，倒不是在于私企国企，关键在于SPACEX是一个全新的公司，这一大票新宇航公司的建立者们以前是玩儿IT的，和航太科技基本不沾边儿。就算给足技术和资金，10年内发展到这个程度，都很可观，更何况不是。

从没造过火箭的，突然什么都会造了，可能么，什么理论了，实验了，都不用了，肯定是站在别人的肩膀上才能做到

SPACEX company and obital sciences corp.这俩公司的成功主要是资本及管理上的成功，其他的都是NASA的，不过美国人这一目标是非常合理的，既发展民间，又节省了官方开支。

这算是美帝在航天体制方面的创新和探索，利用民企的活力和高效。

但需要明确 他们与其说是公司的老板 不如说是投资方 在美政府大量削减航天项目资金的时候 nasa找了一群人融资继续研究罢了 这些技术可不是一个刚成立几年的企业自己可以研究的。这样奇葩的公司只有钢铁侠里的史塔克工业。。。
