Once again NASA’s RBSP launch on an Atlas V has been scrubbed today. This time the problem was weather violating 4 launch criteria rules as a storm moved onto the cape 45 minutes before T-0. Up until that time the launch had been running smoothly with no problems at all.
The Mission management team are currently safeing the Atlas V booster and Centaur upper stage. The team will then recycle the rocket in preparation for a launch tomorrow 26th August at 4:07 EST (8:07 GMT). The weather outlook for tomorrow is the same as today with a 40% chance of violating the launch rules.
The range beacon issue from yesterdays failed launch attempt was determined to be a transponder on the Atlas V rocket. This was transmitting signals slightly out of specifications. After discussions with the Range Safety Officers it was determined that the launch could continue with the existing hardware.
