Following todays failed launch attempt the Mission Management team have discussed the prospects for launching the Atlas V with twin RBSP spacecraft in the next few days. Bearing in mind that Hurricane Isaac is hurtling across the Caribbean and heading for landfall on the south west coast of Florida in the early hours of Monday morning the managers have decided to wait out the storm.
The Atlas V will be rolled back to the Vertical Integration Facility for protection from the outer edges of the Hurricane as it passes through. The new launch date has been reset for Thursday August 30th at 4:05 EDT (8:05 GMT). This needs final confirmation after obtaining approval from the range.
With this launch date it is likely that the rocket will be rolled out to the launch pad again on Tuesday when Hurricane Isaac will be making landfall once again on the Panhandle in the northern part of Florida.
The official statement from ULA follows:
The launch of an Atlas V carrying NASA’s Radiation Belt Storm Probes (RBSP) payload was scrubbed today due to weather conditions associated with lightning, as well as cumulus and anvil clouds. With the unfavorable weather forecast as a result of Tropical Storm Isaac, the leadership team has decided to roll the Atlas V vehicle back to the Vertical Integration Facility to ensure the launch vehicle and twin RBSP spacecraft are secured and protected from inclement weather. Pending approval from the range, the launch is rescheduled to Thursday, Aug. 30 at 4:05 a.m. Eastern Daylight Time.
