14 DAY TRIAL // A host of atmospheric violations prevented the launch of the twin NASA Radiation Belt Storm Probes (RBSP) spacecraft on Sunday, August 26. Mission managers were forced to reschedule takeoff for this Thursday, August 30.
Destined to study the two Van Allen radiation belts surrounding Earth, the RBSP spacecraft were originally scheduled to takeoff about a week ago. Launch was delayed twice on account of technical glitches, and again on Saturday and Sunday, following bad weather.
The NASA Weather Office announced a 40 percent chance of favorable weather for Sunday, which did not materialize. Tropical Storm Isaac intensified, producing anvil and cumulus clouds, as well as conditions associated with lightning.
On Thursday, the RBSP launch window opens at 4:05 am EDT (0805 GMT), and lasts for about 20 minutes. The twin vehicles will be carried to orbit by an ULA Atlas V delivery system.
