NASA計劃建造人類最強動力火箭
http://news.sina.com 2011年09月14日 11:52 僑報
【僑報編譯巴斯聞9月14日報道】據美聯社報道，美國宇航局已經在醞釀製造世界上動力最強的火箭，它可以飛向遠離地球之處，甚至超越月球。
宇航局局長博爾登與數位國會議員在周三推出了奧巴馬政府推遲已久的火箭設計的總體計劃。這種火箭系統被稱作太空發射系統。這一耗資數十億美元的 計劃將在火箭頂端放置載人太空艙。如果一切如期完成的話，該系統第一次的發射將是10年之後。該系統的無人發射測試預計將在6年後在佛羅裡達州的卡納維爾 角進行。
宇航局的探索與行動負責人格斯藤邁爾稱該火箭是人類建造的最大、最強動力的火箭。當然建造這種火箭非常困難。他在周三舉行的一個電話簡報會中說，當宇航局建造了這種火箭之後，我們將有能力超越低地球軌道，世界上還沒有其他國家能做到這一點。
即使是該火箭的最小型的早期原型也將比推送阿波羅宇航員登月的土星五號火箭的推動力強10%。當它的體型達到更加實際的大小時，它的動力將比土星五號火箭的推動力強20%。
來自佛羅裡達州的民主黨籍參議員納爾遜指出，在宇航局制定這一預計耗資350億美元的火箭系統之時，正值美國經濟遭遇挑戰的時候。
納爾遜將該研發計劃在未來5年中的成本定在大約為180億美元。但這一預估成本大多與2017年進行第一次測試飛行的研發和設計有關，它將不包括後期的火箭生産成本。

NASA宣佈大型太空計畫 目標登陸火星
http://news.sina.com 2011年09月15日 05:29 中國日報
（華盛頓十四日電）美國國家航空暨太空總署(NASA)14日宣佈大型太空升空計畫，能讓載人太空船輕鬆衝出近地軌道，最終飛抵火星。
NASA主席勃登(Charles Bolden)揭曉新太空發射系統(Space Launch System)，並自豪是農神5號火箭(Saturn V)載美國太空人登月以來，最具威力的火箭。
新太空發射系統2017年前都還在建造階段，耗資估350億美元，能填補30年曆史的美國太空梭7月退役後遺下的空缺。
NASA表示，新火箭更具威力，載運量更高，能突破近地軌道，直奔火星。
藉由這項計畫，NASA可望在2025年進行小行星計畫。NASA表示預料會讓太空人飛抵火星附近，不過真正登陸火星，至少還要等到2030年。

美國太空總署(NASA)公佈新型太空探測系統
The Space Launch System, or SLS, will be designed to carry the Orion Multi-Purpose Crew Vehicle, as well as important cargo, equipment and science experiments to Earth's orbit and destinations beyond. Additionally, the SLS will serve as a back up for commercial and international partner transportation services to the International Space Station.
"This launch system will create good-paying American jobs, ensure continued U.S. leadership in space, and inspire millions around the world," NASA Administrator Charles Bolden said. "President Obama challenged us to be bold and dream big, and that's exactly what we are doing at NASA. While I was proud to fly on the space shuttle, kids today can now dream of one day walking on Mars."
The SLS rocket will incorporate technological investments from the Space Shuttle program and the Constellation program in order to take advantage of proven hardware and cutting-edge tooling and manufacturing technology that will significantly reduce development and operations costs. It will use a liquid hydrogen and liquid oxygen propulsion system, which will include the RS-25D/E from the Space Shuttle program for the core stage and the J-2X engine for the upper stage.

It will use a liquid hydrogen and liquid oxygen propulsion system, which will include the RS-25D/E from the Space Shuttle program for the core stage and the J-2X engine for the upper stage.
SLS will also use solid rocket boosters for the initial development flights, while follow-on boosters will be competed based on performance requirements and affordability considerations. The SLS will have an initial lift capacity of 70 metric tons (mT) and will be evolvable to 130 mT. The first developmental flight, or mission, is targeted for the end of 2017.

This specific architecture was selected, largely because it utilizes an evolvable development approach, which allows NASA to address high-cost development activities early on in the program and take advantage of higher buying power before inflation erodes the available funding of a fixed budget. This architecture also enables NASA to leverage existing capabilities and lower development costs by using liquid hydrogen and liquid oxygen for both the core and upper stages.

NASA has selected the design of a new Space Launch System that will take the agency's astronauts farther into space than ever before, create high-quality jobs here at home, and provide the cornerstone for America's future human space exploration efforts. The booster will be America’s most powerful since the Saturn V rocket that carried Apollo astronauts to the moon and will launch humans to places no one has gone before.
The SLS will carry human crews beyond low Earth orbit in the Orion Multi-Purpose Crew Vehicle. The rocket will use a liquid hydrogen and liquid oxygen fuel system, where RS-25D/E engines will provide the core propulsion and the J2X engine is planned for use in the upper stage.
Additionally, this architecture provides a modular launch vehicle that can be configured for specific mission needs using a variation of common elements. NASA may not need to lift 130 mT for each mission and the flexibility of this modular architecture allows the agency to use different core stage, upper stage, and first-stage booster combinations to achieve the most efficient launch vehicle for the desired mission.
"NASA has been making steady progress toward realizing the president's goal of deep space exploration, while doing so in a more affordable way," NASA Deputy Administrator Lori Garver said. "We have been driving down the costs on the Space Launch System and Orion contracts by adopting new ways of doing business and project hundreds of millions of dollars of savings each year."

The Space Launch System will be NASA's first exploration-class vehicle since the Saturn V took American astronauts to the moon over 40 years ago. With its superior lift capability, the SLS will expand our reach in the solar system and allow us to explore cis-lunar space, near-Earth asteroids, Mars and its moons and beyond. We will learn more about how the solar system formed, where Earth' water and organics originated and how life might be sustained in places far from our Earth's atmosphere and expand the boundaries of human exploration. These discoveries will change the way we understand ourselves, our planet, and its place in the universe.

ＮＡＳＡ衛星恐墜地 恐砸到人
http://news.sina.com 2011年09月10日 05:26 中國日報
（綜合九日外電）美國國家航太總署（ＮＡＳＡ）一具發射迄今已二十年的失靈人造衛星，將在九月底到十月間墜落地球，衛星碎片可能散落在六大洲任何地區，所幸衛星碎片砸到人的機率不高，估計只有三千兩百分之一，因為大部分太空殘骸在進入地球大氣層時就燒掉了。
ＮＡＳＡ表示，五．四公噸重的「高層大氣研究衛星」（Upper Atmosphere Research Satellite，UARS），用於測量空氣中的化學物質，早在二○○五年便已耗盡燃料，將失控脫離環地軌道墜落地球，最後大概只會剩下五百四十四．三 二公斤的金屬。美國加州范登堡空軍基地美軍戰略指揮部的聯合太空任務中心，雖然在追蹤UARS，但ＮＡＳＡ坦承不知道UARS的碎片會落在哪裏，只知道會 散落在北緯五十七度到南緯五十七度之間的任何地點、長度超過八百零四公里的區域，可能是蘇格蘭或智利等地。
相較於過去墜落地球的人造天體，UARS的重量顯然輕得多。二○○一年墜落南太平洋的俄羅斯「和平號」太空站（Mir）重達一百二十三公噸；一 九七九年墜落印度洋及人煙稀少的澳洲西部地區的首座太空站「天空實驗室」（Skylab），也有九十一公噸重。地球表面有三分之二是海洋，太空殘骸通常會 落入大海。
今年第三個墜地的太空殘骸
ＮＡＳＡ軌道殘骸官員史坦斯伯裡說，從一九五○年代人類進入太空時代開始，一直都有東西重返地球，迄今無人因此受傷。ＮＡＳＡ對太空殘骸訂有規 則，即人造衛星擊中人的機率必須低於一萬分之一，但UARS發射於上述規則施行前的一九九一年，並不適用。面對已失效死亡的人造衛星，ＮＡＳＡ通常會使其 進入「墳場軌道」（a graveyard orbit）運行，以免影響到其他正常運作的衛星，或引導其墜落大海。
對地球近七十億人口來說，被UARS碎片擊中機率是三千兩百分之一，單人被擊中機率只有二十一兆分之一。重量四．五公噸以上太空殘骸，通常不會墜入地球，但哈佛大學天體物理學家麥克道威爾說，UARS是今年第三個墜落地球的太空殘骸。

美國太空總署(NASA)不想讓你知道太陽將會發生的秘密
Uploaded by MaryGreeley on Sep 8, 2011
The secret that NASA don’t want you to know is that the recent solar flares are being cause by the interstellar energy cloud or known as “The Local Fluff”
It’s a highly charged tube shape gas cloud our solar system is just now entering.
they have know about this for at least 2 years.
it is highly radioactive and magnetic and could strip away the protective heliosphere of the sun and earth exposing us to this radiation.
the first signs of this affect would be seen on the sun and then the earth with major earth changes.

美國政府為阿波羅 14號宇航員的月球相機作出起訴
Reuters By Terry Baynes | Reuters – Thu, Jun 30, 2011
NEW YORK (Reuters) - The U.S. government has sued a former NASA astronaut to recover a camera used to explore the moon's surface during the 1971 Apollo 14 mission after seeing it slated for sale in a New York auction.
The lawsuit, filed in Miami federal court on Wednesday, accuses Edgar Mitchell of illegally possessing the camera and attempting to sell it for profit.
In March, NASA learned that the British auction house Bonhams was planning to sell the camera at an upcoming Space History Sale, according to the suit.
The item was labeled "Movie Camera from the Lunar Surface" and billed as one of two cameras from the Apollo 14's lunar module Antares. The lot description said the item came "directly from the collection" of pilot Edgar Mitchell and had a pre-sale estimate of $60,000 to $80,000, the suit said.
Mitchell was a lunar module pilot on Apollo 14, which launched its nine-day mission in 1971 under the command of Alan Shepard. The sixth person to walk on the moon, Mitchell is now retired and runs a website selling his autographed picture.
He has made headlines in the past for his stated belief in the existence of extraterrestrial life.
"All equipment and property used during NASA operations remains the property of NASA unless explicitly released or transferred to another party," the government suit said, adding NASA had no record of the camera being given to Mitchell.
The suit said the government had made repeated requests to Mitchell and his lawyer to return the camera but received no response.
Mitchell's lawyer, Donald Jacobson, said NASA management was aware of and approved Mitchell's ownership of the camera 40 years ago.
"Objects from the lunar trips to the moon were ultimately mounted and then presented to the astronauts as a gift after they had helped NASA on a mission," Jacobson said.
Bonhams said in an emailed statement that the camera had been slated to be auctioned off in May when it learned about the ownership dispute from NASA. The auction house withdrew the camera from sale "pending further discussion between NASA and the consignor," a Bonhams spokesperson said.
The government is asking the court to stop Mitchell from selling the camera to anyone, to order its return and to declare that the United States has "good, clean and exclusive title" to the camera.

太空人銳減 NASA發展受限
September 08, 2011 06:00 AM
一個非營利的科技政策顧問組織7日發表報告說，美國沒有足夠的太空人，不能滿足未來幾年內不斷變化的載人太空飛行需求。
「全國研究委員會」(National Research Council)的報告指出，美國太空人隊伍的萎縮，對美國在載人太空飛行的投資帶來風險，美國航空暨太空總署(NASA)應採取措施，擴大太空人隊伍。
該委員會共同主席、前NASA副署長、指揮三次太空梭飛行的格雷戈里(Frederick Gregory)表示﹕「從供應鏈角度看，太空人的選拔和訓練，對人員的短缺非常敏感。針對具體任務和角色進行訓練的太空人，不能輕易互換。」
在太空梭世代高峰期的1999年，國際太空站正在修建期間，NASA保持著一支150名太空人的隊伍。但到2011年，隨著太空梭計畫在實施30年之後結束，美國太空人數減少到61人，使俄羅斯成為唯一有能力載人去國際太空站的國家。
NASA已經決定，在2016年之前，最少要保持55至60名現役美國太空人，屆時民營工業界可能已測試一種新型的美國太空船，可再度載人進入太空。至於載人去火星或小行星等深度太空飛行任務，將是2025年以後的事情。
完成這些太空任務需要培訓更多太空人，讓太空人在太空停留更長時間，接受更多太空輻射。此外，還存在太空人生病或疲倦的較大風險，可能導致太空人提前退休或無法完成未來飛行任務。該委員會說，雖然未來數年內，每年平均參加飛行的美國太空人數，將從太空梭高峰時期的28人減少至六人，美國仍需要保持較多太空人。
