We will be extending this programmed hold period at T-minus 4 minutes while engineers continue to work a technical issue. Our launch window tonight extends 44 minutes, giving us additional time to work the issue.

Мы продлим этот запрограммированный период удержания на Т-минус 4 минуты, пока инженеры продолжают работать над технической проблемой. Наше окно запуска сегодня вечером продлевается на 44 минуты, что дает нам дополнительное время для решения проблемы.

ULA  @ulalaunch
The launch of a United Launch Alliance Atlas V carrying the ViaSat-3 F2 mission for Viasat is scrubbed for tonight's launch attempt due to a reoccurrence of the issue with the Atlas V booster liquid oxygen tank vent valve.
The team will evaluate the hardware, and we will release a new launch date when available.

"...отложен из-за повторения проблемы с клапаном вентиляции бака жидкого кислорода ракеты-носителя Atlas V."
Новая дата будет объявлена позднее.

New hazard area's for the Atlas V 551 launch of ViaSat-3 F2 are out, and they indicate that ULA is now targeting NET November 14th at 03:00 UTC. Two previous launch attempts were scrubbed due to an issue with the Atlas V booster LOX tank vent valve.

Интересно, запуск и КА застрахованы? 

[Брабонт]

Хороший вопрос. Явных страховок на предстоящий пуск в сети пока не просматривается.

ULA  @ulalaunch
The launch of a United Launch Alliance Atlas V carrying the ViaSat-3 F2 mission for Viasat is now planned for no earlier than Thursday, Nov. 13.

To ensure compliance with the recent FAA order regarding launch times, the launch is scheduled for 10:04 p.m. EST at the opening of a 44-minute window, from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida.
 
Following the scrub last week due to a faulty booster liquid oxygen tank vent valve, the team at the Cape removed and replaced it with a new valve in preparation for this launch attempt.

Main engine cutoff 2, or MECO 2, is confirmed for the Centaur upper stage. The Atlas V rocket has reached an intermediate geosynchronous transfer orbit for tonight's the ViaSat-3 F2 mission. The rocket will coast in altitude for the next three hours before ignition of the final launch burn to optimize the payload's deployment orbit. http://bit.ly/av_viasat

While our webcast has concluded, our live launch blog will continue through completion of the mission with spacecraft deployment more than three hours from now.
To recap, ULA launched the Atlas V at 10:04 p.m. EST (0304 UTC) from Cape Canaveral. The rocket is traveling through space on its 3.5-hour mission to deliver the ViaSat-3 F2 ultra-high-capacity satellite into an optimized transfer orbit for @viasat. http://bit.ly/av_viasat

По средней высоте объект В выше, чем объект А.

Вряд ли коррекция, скорее корректировка начального набора

к тому же наклонение изменено у обоих объектов. В также выше, чем А.

За следующую неделю A поднялся почти на 35 км - спутник. Ну и бог с ним.
Но объект B за ту же неделю опустился на 1,5 км!   Почти плавно, за 6 измерений.

Это-то при перигее 12000 км.
