Pad re-entry team is heading to pad.  They will have to be cleared through road block and then hold before proceeding to pad to collect gear and protective equipment before going to the liquid oxygen farm to work on the valve.

If you are just joining us, a ground system valve problem interrupted the countdown to today's Atlas V rocket launch. A team was sent to the pad to troubleshoot, and those efforts are continuing. The countdown clock is holding prior to the start of fueling operations.

Good afternoon Atlas V. Currently in a hold, but not her fault (GSE issue, being worked on right now).

Sounds like the valve issue has not been resolved and a backup system is experiencing similar issues.  Standing by for more updates.

Запуск новейшего разведспутника США NROL-101 вновь перенесен из-за неполадки
05.11.2020 2:55:02

Вашингтон. 5 ноября. ИНТЕРФАКС - Запуск тяжелой ракеты-носителя Atlas V с секретным спутником NROL-101 Национального управления военно-космической разведки США (NRO), планировавшийся в четверг, перенесен, по меньшей мере, на 48 часов из-за новой технической проблемы, сообщила компания-оператор United Launch Alliance (ULA).

Запуск был отменен примерно за час до старта из-за проблемы в наземной системе подачи жидкого кислорода, следует из сообщения компании ULA, которая является совместным предприятием корпораций Boeing и Lockheed Martin, осуществляющим запуски в интересах Пентагона и американского разведывательного сообщества.

Спойлер

Первоначально запуск ракеты планировалось осуществить еще 4 ноября по московскому времени, но из-за возникшей утечки в наземной системе кондиционирования полезной нагрузки он был перенесен на сутки. Ракету вернули со стартового стола в цех вертикальной сборки для устранения неполадки.

О целях, орбите, размере и других характеристиках секретного американского спутника NROL-101 официально не сообщается. Миссия и возможности спутников данного типа строго засекречены.

Между тем, по имеющимся данным, тяжелый спутник NROL-101, вес которого достигает трех тонн, предназначен для ведения радиоэлектронной разведки.

По факту пуск был отменён за 1 ч 47 мин до старта...
