Super-cold liquid propellants continue to pump into the massive orange external tank of space shuttle Discovery this evening. The fuel sensors in the tank are recording proper readings and no technical issues have developed in the countdown. The tank is being loaded with liquid hydrogen and liquid oxygen to be used during launch by Discovery's three main engines. The weather forecast continues to call for an 80 percent chance of acceptable conditions. Liftoff remains on schedule for 1:36 a.m. EDT.
