Did they run out of launch window?  Or was no reason given for going from the T-4 minutes to scrub?

(I lost the web cast after they recycled to T-4 minutes.)

We don't know as they didn't say what the launch window is (see tweet below). They could have either run out of window or the weather looked like it wasn't going to improve.

"@sahgma NRO launch windows aren't publicly released."

Some might question the wisdom of trying to launch with such a poor upfront weather prediction, is that normal when the odds of good weather are so low?

It could even be a hardware problem, as surprising it to even think that. Atlas-V and Centaur have both had some hiccups of late (although nothing frequent enough to suggest a trend).

#AtlasV #NROL52 launch scrubbed today due to an issue with a telemetry transmitter on the rocket.

The team will replace and retest the hardware in the Vertical Integration Facility prior to another launch attempt. #AtlasV #NROL52

A new #AtlasV #NROL52 launch date will be released when itís established.

The Atlas V scrub record has been broken. The previous record was 2 scrubs with a successful launch on the 3rd attempt.
