美火箭升空后爆炸 太空站补给任务3度失败

This June 28, 2015 sequence of images from NASA TV shows the SpaceX Falcon 9 rocket with the unmanned Dragon cargo capsule on board exploding shortly after launching from Cape Canaveral, Florida. SpaceX rocket exploded less than three minutes after liftoff from Cape Canaveral, Florida on Sunday, in the first major disaster for the fast-charging company headed by Internet tycoon Elon Musk.The accident was the third in less than a year involving US and Russian supply ships bound for the International Space Station, and raised new concerns about the flow of food and gear to the astronauts living in orbit. Skies were sunny and clear for the 10:21 am (1421 GMT) launch of the gleaming white Falcon 9 rocket that was meant to propel the Dragon cargo ship on a routine supply mission, the seventh for SpaceX so far. But two minutes, 19 seconds into the flight, contact was lost. Live television images from SpaceX's webcast and NASA television showed a huge puff of smoke billowing outward for several seconds, then tiny bits of the rocket falling like confetti against a backdrop of blue sky.AFP PHOTO / HANDOUT / NASA TV                     == RESTRICTED TO EDITORIAL USE / MANDATORY CREDIT: "AFP PHOTO / HANDOUT / NASATV  "/ NO MARKETING / NO ADVERTISING CAMPAIGNS / NO A LA CARTE SALES / DISTRIBUTED AS A SERVICE TO CLIENTS ==

(华盛顿29日讯)美国一枚运载补给物的火箭28日升空不久后爆炸解体,国际太空站补给任务第3次失败。

美国公司“太空探索技术”当天在佛州卡纳维拉尔角空军基地,发射搭载“龙飞船”的可回收火箭“猎鹰9号”升空,执行国际太空站补给任务。

“龙飞船”当时携带2500公斤的净水、食物以及科学实验用品。在升空2分钟后突然在空中爆炸解体,碎片落入大西洋。

“太空探索技术”总执行长马斯克表示,火箭爆炸或因“液氧罐出现问题”所致。这是该公司自2012年以来,第8次执行太空站补给任务,也是第一次失败。

供给仍充足

这也是国际太空站补给任务第3次失败。

不过美国太空总署局长博尔登表示,太空站的3名太空人目前“仍有足够未来数月的供应品。”

马斯克表示,他不会放弃火箭回收的尝试,“如果火箭重复使用,那进入太空的成本可降低百倍。”
