Valve repair the problem the U.S. Space Agency 14, NASA said the space station outside of a pressurized valve system failure, may need to "find" one additional space shuttle astronaut crew to repair spacewalk. NASA officials 罗恩斯潘塞 for flight, said the ground flight control personnel have been several attempts by remote control means to open this valve, but were unsuccessful. If the ground staff could not rule out that the ultimate failure, "discovered" there is a need for an astronaut outside the space program operations. "Discovery" after docking with the space station, crew and astronaut Clayton Anderson 里克马斯特拉 Keogh has completed the planned spacewalk mission 3. Spencer said the U.S. space agency will be the 15th final decision on whether to send the two of them to conduct another spacewalk to deal with valve failure. Space Station on the right valve of a pressurized system 13 can not open. This system is mainly a large radiator for the space station's ammonia pressure. Currently the station's cooling system in good working condition, but the space station by the end of April will mark a time of sunshine is more adequate, because if the radiator valve problem will stop working, half of the station may be forced to shut down electronic equipment. "Discovery" on April 5 launch carrying seven astronauts. If the astronauts need to increase a space walk, "Discovery" was the mandate of the original 13-day period will be extended to 15 days.

美航天局阀门修理问题
美航天局阀门修理问题 美国航天局１４日说，空间站外一个加压系统的阀门出现故障，可能需要“发现”号航天飞机机组宇航员增加一次太空行走进行修理。 　　美国航天局负责飞行的官员罗恩·斯潘塞介绍说，地面飞行控制人员已经几次尝试通过遥控手段打开这个问题阀门，但均告失败。如果地面人员最终无法排除这一故障，“发现”号宇航员就有必要进行一次计划外的太空作业。 　　“发现”号与空间站对接后，机组宇航员里克·马斯特拉基奥和克莱顿·安德森已经完成了计划中的３次太空行走任务。斯潘塞说，美航天局将于１５日最终决定是否派遣他们二人再次进行太空行走处理阀门故障。 　　空间站右侧一个加压系统的阀门１３日无法打开。这一系统主要是为空间站一个大型散热器中的氨加压。目前空间站的冷却系统工作状况良好，不过空间站４月底将迎来一段日照更为充足的时间，如果散热器届时因为这个阀门的问题停止工作，空间站上的半数电子设备可能将被迫关闭。 　　“发现”号４月５日搭载７名宇航员升空。如果宇航员需要增加一次太空行走，“发现”号原定１３天的任务期将延长至１５天。
