United Launch Alliance (ULA) has delayed the upcoming launch of a NASA communications satellite by one day to replace a launch vehicle component. The Atlas 5 401 launch of the TDRS-K satellite is now planned for launch on the evening of January 30 from Cape Canaveral. ULA said it pushed back the launch a day in order to replace a component part of the rocket's ordnance system for separating the booster's upper stage after it "demonstrated an anomalous signal" during tests. The satellite carried by the Atlas will be the latest in the series of Tracking and Data Relay Satellites used to relay communications from the ISS and other orbiting spacecraft.
