美國宇宙飛船前往國際空間站

A commercial SpaceX cargo ship has successfully launched from Cape Canaveral, in the southeastern U.S. state of Florida, carrying supplies and experiments for the International Space Station.
The ship, perched atop a Falcon Nine Rocket, took off at 1:52 a.m. (0552 UTC) and is expected to arrive at the ISS early Tuesday.

Sunday's weather was ideal for the launch, unlike Saturday when rain forced the launch to be postponed.

The more than 2,200 kilograms of supplies includes the first 3-D printer to be used on the space station.

The space agency envisions astronauts one day using the printer to manufacture spare parts as needed.

The mission is the fifth for SpaceX.美國的SpaceX公司的商用貨運飛船星期天從美國東南地區的佛羅里達州卡納維拉爾角成功發射，飛船上載有國際空間站所需物資和實驗設備。

運載飛船的獵鷹9型火箭預計星期二抵達國際空間站。

星期天的天氣對發射非常理想。星期六的大雨迫使飛船的發射時間推遲。

2200多公斤的物資包括將第一次在空間站使用的三維打印機。

美國宇航局希望，宇航員未來可以用三維打印機製造所需零件。

這是SpaceX宇宙飛船的第五次航天飛行。
