刚才看到新闻

英国推出了太空旅游推介礼

你们觉得太空旅游能够实现吗？

新闻报道内容：

1。目前200张票已经售空，每张票加200万美元

2。每星期一趟

3。飞行速度比目前的火箭快4倍




分享一下而已

欧洲的我不懂哦
但是我最近看报章说美国的 low cost 火箭发射。。。。。。。。。。。。。。。。。。。失败了。。。因为空气动力学问题（aerodynamic）。。也就是说还要一段时间才能梦想成真。。。

SpaceShipOne captures X Prize
Privately funded craft reaches altitude requirement

MOJAVE DESERT, California (CNN) -- SpaceShipOne achieved its most spectacular flight yet, climbing to an altitude of 377,591 feet (71 1/2 miles) to win the $10 million Ansari X Prize on Monday.

X Prize officials said it set an altitude record exceeding the military X-15's top altitude of 354,200 feet (67 miles) set on August 22, 1963.

With a wish of "Good luck and Godspeed," mission control sent the privately funded craft toward space for the second time in a week, the requirements for winning the X Prize.

"Today we have made history. Today we go to the stars," said Peter Diamandis, co-founder of the X Prize Foundation.

The $10 million award is intended to spur civilian spaceflight.

"You have raised a tide that will bring billions of dollars into the industry and fund other teams to compete," Diamandis said. "We will begin a new era of spaceflight."

The craft left a near perfect dovetail of exhaust contrails with the White Knight turbo jet, which carried it aloft, as its rocket ignited for 84 seconds. The rocket burn sent SpaceShipOne on a trajectory that sent it climbing for almost a minute after the engine shut down.

"It looks great," said Brian Binnie, SpaceShipOne's pilot, on his way up to space at Mach 3.

Binnie, now only the second person in history to earn his commercial astronaut wings, reported a shaky flight with "a little roll" but did not experience the 29 rolls Mike Melvill experienced last week.

"The experience is quite literally a rush," he said. "You light off the vehicle and the world wakes up around you."

He said the view from above could not be conveyed in the images.

Paul Allen, who financed the program, Richard Branson, who recently founded Virgin Galactic for space tourism, and Burt Rutan greeted the newly minted astronaut on the runway. Brinnie's family also joined him on the podium.

Space ShipOne and White Knight, featured a new paint job promoting Virgin Galactic, Branson's new venture, which recently announced a deal to license the SpaceShipOne technology for a fleet of commercial spacecraft

Winning the X Prize with SpaceShipOne is only the beginning for Rutan.

"I have a hell of a lot bigger goal now (than NASA)," he said.

He is now determined to supply the craft for Virgin Galactic.

"I absolutely have to develop a space tourism system that is at least 100 times safer than anything that has flown man into space, and probably significantly more than that," Rutan said.

After some unexpected acrobatics during the the last flight, Rutan said Monday's would be a smooth one, but he was prepared for stability issues.

"We believe we have solved these and we don't believe we'll see the rolls tomorrow," he said Sunday. "But if we do, we don't believe they're dangerous. ... After all, what we're doing is research."

The spacecraft was outfitted with a stronger engine and some aerodynamic modifications from its first record-breaking flight into space on June 21.

Melvill flew the craft's first mission to space and reached, just barely, the required 62-mile altitude, passing the internationally recognized boundary of space. Wind shear and a jammed control on the tail meant the craft veered about 20 miles off course, but it returned for a smooth landing. It was only SpaceShipOne's fourth flight using the rocket engine

On Wednesday, SpaceShipOne streaked even higher to 337, 569 feet (64 miles). However, during its ascent, the private spacecraft began a series of rolls that Melvill brought under control only after ending the rocket burn 11 seconds early.

SpaceShipOne's thrust was provided by two innocuous substances that, when mixed together, are explosive: nitrous oxide and rubber.

A fuel tank about six feet in diameter at the center of the craft holds liquid nitrous oxide, also known as laughing gas. A hollow tube leading from the tank to the engine nozzle is filled with solid rubber. The combustive combination produces thousands of pounds of thrust, although exact amount remains secret.

The nonprofit X Prize Foundation is sponsoring the contest to promote the development of a low-cost, efficient craft for space tourism in the same way prize competitions stimulated commercial aviation in the early 20th century.

The prize is fully funded through the end of the year.

The Federal Aviation Administration commended Scaled Composites on accomplishment and the prospects for commercial space flight.

"We do see this as the frontier of transportation around the around the world," said Marion Blakely, administrator of the FAA. "We know there will be risks, but those are risks are worth taking."

Branson, chairman of Virgin Atlantic Airways, announced last Monday that he would invest $25 million in a new space venture, to be called Virgin Galactic. The project will license Scaled Composite's SpaceShipOne technology for commercial suborbital flights starting at about $200,000.

Branson expects it could fly 3,000 people within five years.

"The development will also allow every country in the world to have their own astronauts rather than the privileged few," he said.

我本来也想贴上来的，居然给楼主抢先一步
不过，我看到的是音速四倍，Mach 4,不是火箭速度四倍，还有就是初步售价是200K，而并非2 million。

哈哈，我好像误导人们

刚才看新闻，大概大概而已

原来是mach4，

火箭是mach how much?

200k,坐在火箭里面不动几天，我会死去

你提出的问题，值得深思。
以前我有看过一些书，里面有提到火箭必须飞到一定的速度，才能脱离地心引力。
要去搜寻一下，有一点忘记了。

不就是牛顿的 gravitation law。。。11km/s (??unit) 忘了。。。主要是两个：1.达到重力平衡点速度  2.冲出地球引力的速度

是escape velocity吗？

原谅小弟孤陋寡闻，我这个阶段还没有学到这样多，很多东西才只是大概"看过"而已。

中五课程没有吗？
这个在任何讲于航太的知识都会提到

SPM课程只有教到Hukum Gerakan Newton 1,2,3。Form 6物理应该才有学到。
