Пошла задержка пуска.

1837 GMT (2:37 p.m. EDT)

HOLD EXTENDED. Liftoff will not occur at 2:46 p.m. EDT while the Centaur interstage purge issue continues to be worked. No new time has been set yet.

1840 GMT (2:40 p.m. EDT)

ULA says engineers are looking at options to resolve this purge problem, which will delay liftoff today by a few minutes at least. A heater over-temperature indication and no downstream pressure indications showed the ground purge to the Centaur interstage adapter area of the vehicle was receiving no flow.

1843 GMT (2:43 p.m. EDT)
The anomaly team is putting together a plan to send a special team into the pad to check the configuration of a manual valve within the mobile launch platform upon which the Atlas rocket sits. That valve could be mis-configured, and resetting it would allow the rocket to launch today.

Обсуждается возможный поход на стартовую позицию... Ждём-с.

Нет готовности от разгонника?

1845 GMT (2:45 p.m. EDT)
Dispatching the crew to the launch pad, however, would present a lengthy hold here at T-minus 4 minutes, but the potential to still launch today. The Atlas team has until 4:46 p.m. EDT to get the rocket airborne this afternoon.

The weather is fine and no other technical issues have been noted throughout the countdown.

Проблема №2 - какой-то гад излучает к югу-юго-востоку от мыса. Отловить и заглушить...

1853 GMT (2:53 p.m. EDT)
Another item has popped up. The Range is detected some frequency interference southeast of the launch pad, ULA reports, and that needs to be cleared before launch can occur.

1850 GMT (2:50 p.m. EDT)
So to recap, the countdown is holding at the T-minus 4 minute mark while engineers work in a no-flow problem with the ground-fed purge to the Centaur interstage adapter. The available launch window today extends to 4:46 p.m. EDT, but a new target liftoff time has not been established.

No favorable conclusion for options for a launch today, but still no final decision.

Still in a holding pattern at this time. The anomaly team should be briefing management shortly. http://tinyurl.com/GoAEHF2 #AEHF

Still in a holding pattern while the purge problem continues to be evaluated and the options discussed. No favorable outcome to report from those assessments thus far.
