Space Shuttle managers will brief reporters today about NASA’s Space Shuttle Return to Flight mission (STS-114). The news conference starts no earlier than 5:30 p.m. EDT. It will be live on NASA TV from Kennedy Space Center, Fla. Questions will be taken from participating NASA locations.

Managers and engineers have been developing troubleshooting plans for a liquid hydrogen low-level fuel sensor inside the Shuttle’s External Tank. The sensor failed a routine pre-launch check during the countdown July 13, causing NASA to postpone Discovery’s first launch attempt. The next attempt will take place no earlier than July 26.

NASA TV is carried by MPEG-2 digital signal accessed via satellite AMC-6, at 72 degrees west longitude, transponder 17C, 4040 MHz, vertical polarization. It’s available in Alaska and Hawaii in analog through Return to Flight on AMC-7, at 137 degrees west longitude, Transponder 18, at 4060 MHz, vertical polarization, and audio at 6.8 MHz.
