Launch delayed after 'computer problems' on board commercial rocket

Launch of $133m flight now delayed until Tuesday

A private space cargo firm's historic launch to the International Space Station descended into chaos this morning when the mission was abandoned just one second before lift-off.

The unmanned SpaceX Falcon 9 rocket was set to blast off from Cape Canaveral just before 10am this morning (GMT) along with its Dragon capsule loaded with 1,000lbs of space station provisions.

But with just seconds before the rocket took to the skies, apparent technical problems left it rooted to the launch pad, with lift-off subsequently abandoned for another three days.

So instead of blasting off on a delivery mission to the space station, the rocket stayed on its launch pad amid a cloud of engine exhaust.
The unfortunate delay caught even NASA's most seasoned launch commentator off guard.

'... 3-2-1, zero, and liftoff,' announced commentator George Diller, his voice trailing as the rocket failed to budge. 'We've had a cutoff. Liftoff did not occur.'

Tuesday is the earliest that SpaceX can try again to send its cargo-laden Dragon capsule to the space station.

The California-based company - formally known as Space Exploration Technologies Corp. - is targeting every third day for a launch attempt to save fuel in case of rendezvous problems at the space station.

Ferrying the Dragon capsule into space, the mission to the ISS will be to deliver 1,000 pounds of non-essential cargo after passing a series of test maneuvers over the course of three days.

If successful in its first-of-a kind mission, the company behind the venture SpaceX would collect the remaining payments on the $396 million contract it has with NASA and then enter into a $1.6 billion agreement for 11 more flights to the ISS.5.39.217.761 b9 T8 g( I7 h# T, c8 v) h: n

The Falcon 9 rocket suffers from an 'instantaneous launch window' which means that if they don't take off at the exact scheduled moment they will have to wait till 3.44 a.m on Tuesday for the pad and the ISS to line up again.

This will be the Falcon's third flight as SpaceX have already sent the projectile into space on two previous occasions.tvb now,tvbnow,bttvb5 s0 l: f2 v- g! f

商用飛船出征揭民營太空時代
今日清晨發射赴太空站

由美國私人公司「太空探索技術」(SpaceX)開發的太空船「飛龍」號(Dragon)，預定今日清晨升空，前往國際太空站進行補給任務，有望成為史上首架抵達國際太空站的私人開發太空船，為民營太空運輸年代揭開序幕。

無人太空貨船「飛龍」號將於今日清晨4時55分，在美國佛州卡納維拉爾角空軍基地，搭乘同為SpaceX開發的「獵鷹9」運載火箭升空。公仔箱論壇3 V( z0 J9 z' |4 z( g

若發射成功，「飛龍」號將於3天後飛抵國際太空站下方約2.5公里的軌道，之後太空站與「飛龍」號會精準調校至同樣以每90分鐘繞地球一圈的速度飛行，確保兩者同步前進。

奧巴馬政府為減省開支，去年宣布結束歷史長達30年的穿梭機計劃，讓所有穿梭機退役，改為推動太空總署(NASA)與多家私人企業合作，研發民營商用太空飛船及火箭，發展「太空的士」計劃，為國際太空站運載補給物資，填補穿梭機停飛後美國太空運輸的真空。5.39.217.76# J% [$ d7 P4 k8 P, z) G: z: q

太空專家洛格斯登(John Logsdon)稱，各界對今次升空期望甚殷，儘管只是一次試飛，但如果失敗，選擇結束穿梭機計劃、展開民營航天的NASA將承受嚴重後果。TVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。) K. S* O: ^" h* \

火箭成本較太空總署低五成

SpaceX目前正與波音、Orbital Science、BlueOrigin等企業展開航天工具開發戰。2010年，SpaceX成為首家成功將太空艙發射至地球軌道的企業，並成功以17億美元，開發搭載火箭「獵鷹9」，分析數據顯示，如NASA開發同樣的火箭，成本需40億，意即SpaceX可便宜逾五成，為未來發展更便宜的太空運輸工具帶來突破。( i* d7 h% o. r3 r+ H6 X

專家指出，SpaceX在這場商場競賽中暫時領先，若今次任務成功，將令SpaceX進一步拋離對手，否則可能影響它在2015年發射7人太空船的大計。

雖然國會早前要求NASA選擇集中資助單一企業，以減低投資失敗帶來的財務風險，但NASA強調，競爭對航天工具發展不可或缺。(法新社/路透社/MSNBC)
