Astronaut Mark Kelly is commanding Endeavour's final mission.
在‘奋进’号这最后一次任务中，担任指挥的是美国宇航员马克·凯利。
He shared a few words with mission control about 10 minutes before launch.
"As Americans, we endeavor to build a better life than the generation before, and we endeavor to be a united nation," said Kelly. "In these efforts, we are often tested. This mission represents the power of teamwork, commitment and exploration. It is in the DNA¹ of our great country to reach for the stars and explore. We must not stop."
Kelly's wife, U.S. Congresswoman Gabrielle Giffords, attended Monday's launch. Giffords was severely² wounded during a shooting rampage in Arizona in January and has been recovering at a medical center in Houston, Texas.
凯利的妻子，美国联邦众议员吉福兹，星期一也在场参观发射过程。吉福兹今年一月在亚利桑那州发生的枪击事件中受了重伤，如今正在德克萨斯州休斯顿的医院接受康复治疗中。

The primary objective of Endeavour's 16-day mission is to deliver the Alpha Magnetic Spectrometer to the International Space Station. The spectrometer, or AMS, is a sophisticated detector⁴ that will help researchers study the formation of the universe.
奋进号在这次为时16天的任务中，主要是为国际空间站运送“阿尔法磁谱仪”，这套磁谱仪是精密的侦测仪器，它有助于研究宇宙的形成问题。
It will look for elusive⁵ evidence of anti-matter by searching for anti-carbon and anti-helium molecules⁶ among all discernible particles.
