探測車將發射 揭火星生命之謎

 【00:25】

〔中央社〕小汽車一般大小的核動力火星探測車，本週即將發射，並於9個月後抵達火星，探尋火星過去或現在是否適合生命存在。

美國國家航空暨太空總署（NASA）造價高達25億美元的「火星科學實驗室」（Mars Science Laboratory），預定26日格林威治時間15時02分(Local Time 10:02AM)，自甘迺迪太空中心（Kennedy Space Center）南方的卡納維爾角（CapeCanaveral）空軍基地，由「擎天神五號」（Atlas V）火箭攜帶發射升空。

這是NASA自1970年代啟動維京計畫（Viking）以來，首次展開火星探測之旅，繼續探究地球以外究竟是否有生命存在的老問題。

太空總署宣布，史上最大、最先進的火星探測車將於26日發射，展開尋找火星上可能曾有生命存在或生命存活至今的地點。

重達899公斤的火星科學實驗室，又被稱為「好奇號」。它擁有尖端照相機、機械手臂、行動化學實驗室及能夠迅速掠過岩石的雷射光束，因此被NASA科學家形容為「夢幻探測車」。

Kennedy Space Center Location & Directions

 

Don't miss a trip to Kennedy Space Center, an island wildlife refuge that also serves as NASA's launch headquarters. Just a short drive from Orlando, Daytona Beach and Miami - Kennedy Space Center's location is easy to reach, but beyond your wildest imagination. 

Kennedy Space Center Directions

Using MapQuest® or MSNMaps, use the city "Orsino," and the state "FL." Kennedy Space Center Visitor Complex is located just to the west on 405, between Range Road and East Avenue SW. Using GPS coordinates, enter 28^o31'34.10"N and 80^o40'45.12"W. This will bring you to the intersection of our entrance.

 

From Cocoa Beach on State Road 528

Travel north on A1A to SR 528 west. Take the SR 3 exit (exit # 49) towards Merritt Island/Kennedy Space Center. Turn right (north) onto SR 3 and continue north for approximately ten miles. Turn left (west) onto Space Commerce Way. Turn right (east) onto SR 405. Kennedy Space Center Visitor Complex is located on your right.

From Orlando on State Road 528

Travel east on SR 528 to the SR 407 exit to Kennedy Space Center and Titusville. Take SR 407 until it dead ends into SR 405. Turn right (east) onto SR 405 and follow the signs for Kennedy Space Center. You will travel approximately nine miles on SR 405. Kennedy Space Center Visitor Complex is located on your right.

From Orlando on State Road 50

Travel east on SR 50 until you pass under the I-95 overpass. At the next intersection, turn right (east) onto SR 405 and follow the signs for Kennedy Space Center. You will travel approximately 11 miles on SR 405. Kennedy Space Center Visitor Complex is located on your right.

From Daytona Beach on Interstate 95

Travel along I-95 to Exit #215 (SR 50). Turn left (east) onto SR 50, then turn right (east) on to SR 405 and follow the signs for Kennedy Space Center. You will travel approximately 11 miles on SR 405. Kennedy Space Center Visitor Complex is located on your right.

From Miami on Interstate 95

Travel along I-95 to Exit #212 (SR 407). Head east/north on SR 407 until it dead ends into SR 405. Turn right (east) on SR 405 and follow the signs for Kennedy Space Center. You will travel approximately nine miles on SR 405. Kennedy Space Center Visitor Complex is located on your right.

美探測車升空 尋火星生命

使用核動力 耗資750億元

2011年 11月27日

【施翩╱綜合外電報導】美國航太總署（NASA）於台灣時間昨晚11時許，發射歷來最強力、最先進，使用核動力的六輪火星探測器「好奇號」（Curiosity），預計它在飛行36周後，將登陸火星，尋找火星是否曾經有生命存在的跡象。
NASA是在佛羅里達州卡納維爾角空軍基地，發射了擎天神五號（Atlas V）火箭，將最新的探測車「好奇號」（Curiosity）帶往火星。

懸吊降落隕石坑

外形有如休旅車的好奇號又名「火星科學實驗室」（Mars Science Laboratory），是由NASA耗資25億美元（約750億元台幣）打造。將提供科學家火星地表岩石的詳細資料，有助解開火星是否曾有生命的謎題。
好奇號預計花36周時間往火星方向航行，預計明年8月進入火星大氣層，在距離地面11公里時會打開降落傘，並在離火星地表只剩12公尺時採用「天空起重機」方式，讓起重機與探測器分離，以纜繩懸吊，慢慢降落在火星赤道附近的蓋爾隕石坑（Gale Crater）。

NASA稱夢幻機器

那裡有綿延5公里的高山，以及層層堆積的沉積物，極可能藏有過去有水的證據。
好奇號被NASA科學家稱作「夢幻機器」，它擁有靈活的機械手臂，靠著10種探測儀器執行任務。
而且它比過去的火星探測器更龐大，重899公斤是2003年發射的「機會號」、「精神號」的5倍。降落後將在火星持續23個月的探測任務，時間也是過去的7倍以上。
