衛星撞慧星 ~ Deep Impact's Impactor Meets Its Target

[best-url]

好失望, 期盼了老半天, 待在 電腦前 鎖定 nasa.org 與 開著電視 [中天頻道] 終於等到 13:52 pm 預計撞擊的那一刻...

甚麼也沒看到...

電視新聞報導要在 20 多分鐘之後 才會有 NASA 公佈的畫面...

這枚 "去送死" 的衛星被命名為 Impact (衝擊 or 撞擊 號); 我手上有一個 [ impacts.info ]
(撞擊號 的 資訊) 的域名 ~ 這陣子的點擊 跟往常一樣也沒甚麼不同

應該是【深撞號】吧?!
Deep Impact
到Google查DeepImpact可以查到一些資料，gTLD也只剩下 DeepImapct.Name可註。
不過還是佩服您的熱忱，小弟自從1993年參與的最後一個航太計畫結束後，不只不想碰航太的東西，連科幻片都不想看了。

[哈啦]

deepimpact.com很早就被註了，不知當初註冊者是想幹什麼？而這一陣子流量是否大增？

[Ricado]

2001年註的。
2001年夢公園推出彗星撞地球電影，電影名稱 DeepImpact。

NASA很多計畫的構想都是來自電影。

[哈啦]

原來如此。以後要多注意電影和電視影集了

[ckmarkhsu]

據說這次的構想是來自30年前的"2001太空漫步(遊?)"這本小說

Ricado怎麼會從航太變成軟體工程師阿XD

您該不會是幫忙太空梭寫導航軟體吧XD

能不能分享一下有趣的事情阿 <(_ _)>

小弟對天文物理頗有興趣 :P

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.
