Countdown activities continue to pick up as space shuttle Discovery is a day away from its final launch. Technicians are inspecting the external tank liquid oxygen feedline today. The onboard and ground communications systems will be activated this afternoon and preparations are being made to move the rotating service structure away from the shuttle this evening.
NASA TV will air an STS-133 Countdown Status Briefing at 10:30 a.m. with Steve Payne, NASA test director, Scott Higginbotham, STS-133 payload manager and Kathy Winters, shuttle weather officer.
