美国发射号航天飞机升空

美国"发现号"航天飞机于美国当地时间15日晚19点43分(北京时间16日7时43分)，在肯尼迪航天中心发射升空。

据悉，"发现号"上载有7名宇航员，包括6名美国人和1名日本人。此次发射的任务是为国际空间站装配太阳能电池板。

The space shuttle Discovery lifted off Sunday evening on a mission to the international space station, where Discovery will deliver supplies needed to expand the station's crew to six people.

The shuttle launched at 7:43 p.m. Sunday, after NASA engineers repaired a leaky gas line. The hydrogen leak caused the cancelation of Wednesday's planned launch.

Lead shuttle flight director Mike Moses said repairs on the hydrogen gas vent line went smoothly. The line funnels flammable hydrogen away from the launch pad so it does not present a fire risk during takeoff.

The seven-member shuttle crew will be delivering the final parts needed for an expanded solar energy power system that will allow the station to double its crew to six people. The shuttle crew also will be dropping off Japanese astronaut Koichi Wakata, who will replace NASA's Sandy Magnus on the station.

Officials said the crew had been training and resting up for the mission since Wednesday's.

Earlier this week, Magnus, station commander Michael Fincke and Russian engineer Yury Lonchakov had to take shelter in their Soyuz spacecraft -- a lifeboat of sorts -- when a piece of debris from an earlier mission hurtled uncomfortably close to the station.

The debris, moving about 20,000 mph, came within three miles of the station but caused no damage.

Wednesday's launch postponement was the latest in a series of delays for Discovery as it tries to make the 28th shuttle mission to the space station.
