SCRUB! The persistent gloomy weather at Cape Canaveral this afternoon will keep the United Launch Alliance Delta 4-Heavy rocket from flying today to deliver a classified U.S. national security satellite into space.
A combination of rain, clouds and lightning meant it was unsafe to permit the triple-barrel rocket launch during its lengthy opportunity today.

Liftoff of the NROL-37 mission is rescheduled for Saturday at 1:51 p.m. EDT (1751 GMT). Forecasters say there is a 60 percent chance of acceptable weather then.

Tak už snad! :)

If you are looking for some hope, the launch weather team now predicts a 30 percent chance of GO conditions around 5:40 p.m. EDT (2140 GMT).

After brief respite, multiple weather rules are RED again -- flight thru precipitation, anvil clouds, disturbed weather and electrical potential.

The new target launch time is 2:55 p.m. EDT (1855 GMT), allowing the weather balloon data of high-altitude winds to be received and analyzed.

The weather improvement trend is continuing, with the best shot for launch today likely coming between 2:15 and 3:15 p.m. EDT (1815-1915 GMT), the weather officer indicates. The odds of acceptable weather in the rest of the launch window have been reduced to just 10 percent.

The three liquid oxygen tanks in the Common Booster Cores are conditioned for flight.

Už chybí jen provazochodec.. :)

PRAASHEK: pravděpodobně jo ;))
