NASA says clouds and thunderstorms in Florida could disrupt the launch of twin satellites on a mission to study the moon's gravitation field.
The twin Grail probes are scheduled to be launched Thursday morning from Cape Canaveral, Fla., but storms are expected in the area for the next two days, making a delay a distinct possibility.
"We're going to be sandwiched in between probably two areas of thunderstorms," Grail launch weather officer Joel Tumbiolo said. "Right now, the forecast for the beginning of the launch window is a 60 percent chance of violation."
If Thursday's launch is delayed, the same weather will probably affect chances of a Friday launch as well, he said.
But, he said, the forecast is for conditions to be more favorable on Saturday and Sunday.
"Those days look improved, so we're looking forward to that," Tumbiolo said.
