At NASA's Kennedy Space Center's Launch Pad 39A, technicians are completing repairs on space shuttle Discovery's ground umbilical carrier plate (GUCP). On Nov. 17, the hydrogen vent line was reattached to the GUCP. That vent pipe carries excess hydrogen gas safely away from Discovery to a flare stack, where it is burned off. Teams will analyze the hardware fittings and pressure check the connections to look for any possible leaks. Discovery's next launch window for STS-133 extends from Nov. 30 through Dec. 6.
