NASA and SpaceX launched the Crew-6 mission to the International Space Station (ISS) early Thursday.

周四凌晨，美国国家航空航天局(NASA)和美国太空探索技术公司(SpaceX)成功发射了前往国际空间站(ISS)的Crew-6任务。

The SpaceX Falcon 9 rocket and Dragon spacecraft Endurance roared off Launch Complex 39A at Kennedy Space Center in Florida at 12:34am Eastern Time (0534 GMT) Thursday.

美国东部时间周四凌晨12点34分(格林尼治标准时间0534分)，SpaceX“猎鹰9号”火箭和“龙”飞船“耐力”号，在佛罗里达州肯尼迪航天中心的39A发射场升空。

Shortly after the liftoff, SpaceX confirmed the main engine cutoff and stage separation.

升空后不久，SpaceX确认主引擎关闭，级间分离。

The first stage of the Falcon 9 rocket successfully landed on the "Just Read the Instructions," off the coast of Florida.

“猎鹰9号”火箭芯一级成功降落在佛罗里达州海岸外的“请阅读说明书号”(JRTI)无人回收船上。

The Dragon spacecraft has separated from the second stage and headed to the ISS.

“龙”飞船已经与芯二级成功分离，继续向国际空间站进发。

The mission is the sixth crew rotation flight of a Dragon spacecraft as part of NASA's Commercial Crew Program.

这次任务是NASA商业航天计划的一部分，“龙”飞船的第六次宇航员轮换飞行。

The Crew-6 launch carries NASA astronauts Stephen Bowen and Warren "Woody" Hoburg, as well as United Arab Emirates astronaut Sultan Alneyadi and Roscosmos cosmonaut Andrey Fedyaev to the space station for a science expedition mission.

执行“Crew-6”任务的是NASA宇航员斯蒂芬·鲍恩、沃伦·霍伯格，阿联酋宇航员苏丹·奈亚迪以及俄罗斯宇航员安德烈·费佳耶夫，他们将在空间站执行科学考察使命。

The launch was originally scheduled for Monday but was called off due to a ground systems issue.

发射原定于周一进行，但由于地面系统出现故障而取消。

After a thorough review of the data and ground system, both NASA and SpaceX teams identified a clogged filter on the ground as the cause.

在对数据和地面系统进行彻查后，NASA和SpaceX的团队都认定地面堵塞的原因是过滤器。

SpaceX teams replaced the filter, purged the line of ignition fluid with nitrogen, and verified the lines are clean and ready for the new launch attempt, according to NASA.

NASA称，SpaceX的团队更换了过滤器，用氮气清洗了点火液，并确认了管路的清洁，为新的发射尝试做好了准备。
