3:29 | Mark Carreau - Discovery's astronauts are boarding now. The weather outlook remains 80 percent favorable for a 6:43 p.m., CDT liftoff The hydrogen leak that stopped last Wednesdy's launch attempt did not reappear. There was a problem with a low helium flow in the fuel line connection between the expernal fuel tank and Discovery's rocket engine compartment. Techs send to the pad adjusted the flow and that too appears to be an issue that has come and gone. Some of you have heard about a fruit bat hanging from the fuel tank. A novelty, but not an issue for launch. Not large enough to cause debris damage. |
