    我的讨逆书

    反应强烈?理所当然。这个Pluto小弟一完蛋,我可就成太阳系行星俱乐部里的的边缘小弟了,谁知道哪天再开个什么阴谋家大会,就把我Neptune划成暗行星了(Pluto现在是被陷害成矮行星)。按照这帮阴谋家的白马非马歪理邪说,这些可都不算行星的。
    再说各位优秀青年,从幼儿园开始就有人教你们太阳系有9大行星的骨肉同胞们。现在突然冒出一小撮科学界的败类,告诉你们说你从小学的那错了,按他们在那阴暗的角落里捣鼓出来的最新版强制性行星国家标准ISO9999,冥王星,可爱的冥王星,忠诚地冥王星,美丽的冥王星,已经不再是行星了!这时各位难道就没有一丝一毫发现从小到大被欺骗被愚弄被洗脑的发自心底的愤怒?觉醒吧,地球上的同胞们。匡扶正义,讨奸除孽,天降此大任于我辈。
    Be with me, so we can change the world!

    你开你的阴谋家大会,我认我的冥王星兄弟

    人家Pluto半径怎么说也有1450miles了,虽说跟我们家Neptune的30,199miles不可同日而语。但看看那个整天紧密团结在太阳周围差点儿掉进去的水星也不过才3031miles。凭那帮整天不学无术玩弄权谋搞文字游戏的天文学败类,篡改行星定义,就想把我们唇齿相依的冥王星兄弟做掉,其用心何其毒也!
    冥王星历来是太阳系行星不可分割的一部分。唇亡则齿寒,这些倒行逆施,篡改历史,破坏太阳系和平的的乱臣贼子必定人得而诛之。其谋害太阳系手足兄弟把冥王星从太阳系分割出去的历史罪行是注定要失败的。
    任凭你们修改行星定义也好,篡改中小学教科书也罢,历史终将证明:“太阳系的行星有且仅有9颗!”

    Deep Impact Kicks Off Fourth of July With Deep Space Fireworks

    07.04.05

    After 172 days and 431 million kilometers (268 million miles) of deep space stalking, Deep Impact successfully reached out and touched comet Tempel 1. The collision between the coffee table-sized impactor and city-sized comet occurred at 1:52 a.m. EDT.

    "What a way to kick off America's Independence Day," said Deep Impact Project Manager Rick Grammier of NASA's Jet Propulsion Laboratory, Pasadena, Calif. "The challenges of this mission and teamwork that went into making it a success, should make all of us very proud."

    "This mission is truly a smashing success," said Andy Dantzler, director of NASA's Solar System Division. "Tomorrow and in the days ahead we will know a lot more about the origins of our solar system."

    Official word of the impact came 5 minutes after impact. At 1:57 a.m. EDT, an image from the spacecraft's medium resolution camera downlinked to the computer screens of the mission's science team showed the tell-tale signs of a high-speed impact.

    "The image clearly shows a spectacular impact," said Deep Impact principal investigator Dr. Michael A'Hearn of the University of Maryland, College Park. "With this much data we have a long night ahead of us, but that is what we were hoping for. There is so much here it is difficult to know where to begin."

    The celestial collision and ensuing data collection by the nearby Deep Impact mothership was the climax of a very active 24 hour period for the mission which began with impactor release at 2:07 a.m. EDT on July 3. Deep space maneuvers by the flyby, final checkout of both spacecraft and comet imaging took up most of the next 22 hours. Then, the impactor got down to its last two hours of life.

    "The impactor kicked into its autonomous navigation mode right on time," said Deep Impact navigator Shyam Bhaskaran, of JPL. "Our preliminary analysis indicates the three impactor targeting maneuvers occurred on time at 90, 35 and 12.5 minutes before impact."

    At the moment the impactor was vaporizing itself in its 10 kilometers per second (6.3 miles per second) collision with comet Tempel 1, the Deep Impact flyby spacecraft was monitoring events from nearby. For the following14 minutes the flyby collected and downlinked data as the comet loomed ever closer. Then, as expected at 2:05 a.m. EDT, the flyby stopped collecting data and entered a defensive posture called shield mode where its dust shields protect the spacecraft's vital components during its closest passage through the comet's inner coma. Shield mode ended at 2:32 a.m. EDT when mission control re-established the link with the flyby spacecraft.

    "The flyby surviving closest approach and shield mode has put the cap on an outstanding day," said Grammier. "Soon, we will begin the process of downlinking all the encounter information in one batch and hand it to the science team."

    The goal of the Deep Impact mission is to provide a glimpse beneath the surface of a comet, where material from the solar system's formation remains relatively unchanged. Mission scientists expect the project will answer basic questions about the formation of the solar system, by offering a better look at the nature and composition of the frozen celestial travelers known as comets.

    The University of Maryland is responsible for overall Deep Impact mission science, and project management is handled by JPL. The spacecraft was built for NASA by Ball Aerospace & Technologies Corporation, Boulder, Colo.

    July 4, It's COMET time

    Comet Tempel 1 was discovered in 1867 by Ernst Tempel. The comet has made many passages through the inner solar system orbiting the Sun every 5.5 years. Now it's coming to meet NASA's observatory spacecraft.
