宇航中心

周六去了奥兰多附近的肯尼迪宇航中心。 
震撼!
人类的智慧真是伟大!
万语千言, 不如你们自己看吧。

'Discovery' Lands Safely In California!


Mission control in Houston announced the return of "Discovery":

"Main [landing] gear touchdown. Drag [para]chute deploy. Nose gear touchdown. And 'Discovery' is home."

A few seconds later, shuttle commander Eileen Collins expressed the feelings of the crew, saying: "We're happy to be back, and we congratulate the whole team on a job well done."

Two planned landing attempts in the southeastern state of Florida were canceled earlier on 9 August because of concern about low clouds. The shuttle needs clear visibility for about 8 kilometers to ensure the spacecraft is properly aligned for landing.

After the shuttle's 26 July launch, "Discovery" spent nine days hitched to the International Space Station. In addition to resupplying the station, the "Discovery" crew also removed waste and broken equipment -- one of the main goals of the mission.

Astronauts also conducted three space walks.

Two space walks were used to replace a failed gyroscope and to restore power to another. The gyroscopes control the orientation of the station. After that work, "Discovery" commander Collins was able to confirm that all four of the station's gyroscopes were running simultaneously for the first time in three years.

"We have definitely accomplished our mission objectives," she said.

The two space walks also were used to test repair techniques for the shuttle's thermal tiles in case of damage.

And in the third space walk, astronaut Stephen Robinson put some of those techniques to the test. For the first time on a shuttle mission, he went beneath "Discovery" to gently tug out two protruding thermal-tile fillers that had apparently been damaged during liftoff. Engineers on the ground thought the material could cause overheating during re-entry and perhaps lead to another Columbia-type catastrophe.

Columbia was doomed by a large piece of insulation that broke free from the external fuel tank during launch and caused a hole to ???? in the ship's left wing. As Columbia re-entered the Earth's atmosphere, searing gases melted the wing from the inside, causing the ship to break apart. All seven astronauts aboard were killed.

Because of that tragedy, the shuttle's crew used cameras and lasers to inspect their ship for damage on five different days of the mission. Those inspections alerted ground controllers to the problem with the thermal tiles, which protect the craft from burning up during re-entry.

After his space walk, Robinson spoke about the significance of the repairs.

"The ability to repair goes hand in hand with the ability to inspect. We now know more about our shuttle than any crew has ever known before they came back home," Robinson said. "That's a fantastic step forward. The next step is to be able to repair any damage we happen to have found. Our shuttle didn't require any repair. Just a tiny little dental flossing -- plugging a couple of gap fillers up. But the work that the folks have done on the ground -- and the tests that we've done in orbit this time with the spacewalking -- have laid the first brick in that road. So we're pretty confident that a lot more progress will be made pretty soon."

The shuttle's mission initially had been scheduled to last 12 days. An extra day was added so the crew could transfer as many provisions as possible to the space station amid uncertainty about the date of the next shuttle flight.

The shuttle spent another extra day in orbit after concern over weather in Florida led ground controllers to cancel a landing planned for 8 August.

看到一个小科普:
为什么航天飞机的机体颜色是黑白相间,而不是纯白或纯黑?































航天飞机机体要用可耐几千度高温的绝热瓦覆盖。白色的可耐温度较低,造价也低。用在机体中间部位,因为飞机在大气层中飞行时,这里温度相对比较低;黑色的可耐温度较高,造价也高。所以用在机头和翅膀边缘等部位,因为这些部位的温度较高。

这个宇航中心建的太聪明了。 大大有助于提高民众对宇航事业的热情支持。 连我这个科盲也开始对此倍加关注。

在宇航中心, 看到当年一个个阿菠萝登月火箭发射失败, 宇航员们前赴后继英勇牺牲, 我竟然也热血沸腾。 原来, 除了爱国主义, 还有爱球主义。

今天,Discovery号推迟反航, 我的心悬了起来: 千万不要重蹈2年前Columbia号的覆辙 呀。 

特摘录新闻如下。

USA Today:
CAPE CANAVERAL- All future shuttle flights are on hold indefinitely because of trouble with Discovery's fuel tank - the same problem that caused Columbia to disintegrate while re-entering the Earth's atmosphere in 2003 and which NASA vowed to fix. Members of Congress have expressed doubts about NASA's competence, and the aging shuttles are to be retired in 2010.

Entry director said there was a only slight chance that rain showers at the shuttle's primary landing site in FL would keep the ship from coming home today. The "go/no go" decision was to be made about 80 minutes before the scheduled 4:46 AM EST landing. (事实上, 今早新闻说, 推迟到明天5am) The indefinite grounding of the shuttle has implications for the Hubble Space Telescope, the International Space Station and the shuttle program's next 5 years.

This is not the 1st time the foam insulation on the fuel tank has been a problem. A chunk of it bashed a hole in Columbia's wing, which led to the shuttle's destruction. Despite 2.5 years of work, forma peels off 5 spots on Discovery's tank and overshadowed its mission.

Head of the space station program said Atlantis could launch on the next planned mission no earlier than Sept22. If Atlantis doesn't get off the ground before Setp26 - if it needs a new fuel tank, for example - it'll have to wait till Nov 7-10. The next launch window would be in Marc.

The short launch windows and their infrequency are driven in part by NASA's requirement that liftoff by well-lit so cameras can spot flying debris. The timing is also dictated by the need to line up the shuttle to dock with the space station.

Atlantis also could be delayed by another post-Columbia rule: Asecond shuttle, in this case Discovery, must be ready to rescue the Atlantis crew if something goes wrong. Turning Discovery around fast enough to fulfill the rescue role will be the "real constraint" tot he next launch, NASA official said.

That could have implications for the space station, which is half-built. No other existing space vehicle is big enough to carry pieces of the station. 19 to 20 flights are needed to finish the orbiting laboratory. Shuttle difficulties could also complicate NASA's plan to send astronauts to fix the Hubble Space Telescope, which has dying battery.

谁去了休斯顿?

卡拉, 你没发烧吧?


haha,发没发烧不好说,眼神不济肯定是有的,明明人家露露第一页就说了去的奥兰多。

等我翻翻我的片片,找找以前在休斯顿拍的来对比一下。不过N年前的了,那时候用的还是比较原始的数字相机。。

亲耐的你可真能玩呀,每个周末都不闲着。
想起当年我们发射导弹的情景了,唉,那样的经历恐怕这辈子不会再有了
