Bad weather delays X-37B launch.

Fridays launch was scrubbed due to bad weather, reports. But should now go ahead at 2109 GMT on Saturday. Tanking delays have caused this time to slide to the second launch window for today (2246 GMT)

Thick cumulous clouds were within 10 miles (16 kilometers) of the launch complex, presenting an unacceptable risk of lightning, according to officials with the United Launch Alliance (ULA), which is overseeing the OTV-2’s launch.

“We made a valiant attempt, but the weather is not cooperating for today,” a launch controller said.

The foul weather didn’t catch mission planners off guard — Air Force officials had said in the days leading up to the launch attempt that there was a 70 percent chance of a delay caused by weather.

The next launch opportunity comes tomorrow (March 5) at 4:09 p.m. EST (2109 GMT), ULA officials said. But the lousy weather could still be a problem, with launch controllers estimating a 70 percent chance of another weather delay.
