Space shuttle Endeavour on launching pad, strap reading launch has been delayed\u003cbr/\u003eFor the second time in less a week, a hydrogen gas leak on shuttle Endeavour's fuel tank early on Wednesday forced a launch delay, pushing its space station construction mission into July.\u003cbr/\u003eNASA waited almost an hour after the leak appeared, trying to fix it through remote commands, before calling off the predawn launch attempt.\u003cbr/\u003eLaunch officials said the leak occurred in the same place as one that cropped up on Saturday during fuelling, in the hydrogen gas vent line that hooks up to the external fuel tank.\u003cbr/\u003eOn Wednesday, engineers opened and closed a valve in hopes of stopping the leakage or, at the very least, better\u003cbr/\u003eunderstanding it. \u003cbr/\u003eBut that did not work and the countdown was halted just 3 1/2 hours before the scheduled launch time.\u003cbr/\u003eThe leak seemed to have different characteristics this time, a launch commentator said.\u003cbr/\u003eMission managers had ordered repairs following Saturday's delay. The hook-up itself and two seals were replaced. \u003cbr/\u003eThe same repair worked back in March, when a similar leak stalled a shuttle flight. Engineers, however, never found the cause of the problem.\u003cbr/\u003eThe latest leak occurred a little earlier in the fuelling, said the assistant launch director for the mission.\u003cbr/\u003eWhen Endeavour finally flies, it will be one of the longer international space station visits, nearly two weeks\u003cbr/\u003edocked at the orbiting outpost, and include five spacewalks.\u003cbr/\u003eOnce the shuttle pulls up at the space station, there will be 13 people together in space for the first time ever.\u003cbr/\u003eDelaying until July is expected to push back the next few shuttle flights.\u003cbr/\u003eNASA is up against a 2010 deadline for carrying out its final eight shuttle flights, all of them trips to the space station. \u003cbr/\u003eThe White House wants the three remaining shuttles retired and the space station completed by the end of next year.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex
