維珍商用太空船飛出地球 太空旅遊夢指日可待

維珍集團旗下維珍銀河(Virgin Galactic)一艘「太空船2號」級(SpaceShipTwo)商業載人太空船,週四在加州試飛時一度飛至海拔82.7公里,即到達太空邊緣,令人類向實現太空旅遊夢想又邁進一步。

充當「母機」的雙體運輸機「白色騎士2號」(WhiteKnightTwo)搭載「團結號」(Virgin SpaceShip Unity,VSS Unity)太空船,在「莫哈韋航太港」(Mojave Air and Space Port)起飛,飛至海拔13.7公里時釋放「團結號」。幾秒後,太空船垂直奔向太空,最高飛至離地面82.7公里。美國空軍認定海拔80公里是地球大氣層與太空的分界線。「團結號」上除有兩位機師,亦搭載了4件美國航太總署(NASA)研究貨物,以及一個叫安妮(Annie)的假人乘客。 「團結號」以時速3,063公里的速度重返地球,最後安全著陸,歷時一小時的試飛順利完成。
