Mars Orbiter Launch Delayed

Mictian writes "NASA's newest Mars probe, Mars Reconnaissance Orbiter (MRO), was originally scheduled to be launched from Kennedy Space Center Wednesday morning atop an Atlas 5 rocket. However a potential problem with the Atlas' Redundant Rate Gyro Units (RRGUs), that are part of the vehicle's flight control system, detected at Lockheed Martin's factory has caused the engineers to make sure that the two RRGUs in MRO's rocket are working, thus delaying the launch at least until Thursday morning. There is a 1.5 hour launch window daily until the end of the month."
