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 an issue encountered while cycling the booster liquid oxygen tank vent valve during final checkouts. The team will require additional time for troubleshooting and is setting up for a 24-hour recycle.The launch is now planned for Thurs., Nov. 6 at 10:16 p.m. EST at the opening of a 44-minute window.
The official Atlas V forecast calls for a 50 percent chance of meeting the launch weather rules at Cape Canaveral tonight. Thick-layered clouds over the launch site and rain showers in the area are the main areas of weather concern.
ULA Launch Director James Whelan authorized cryogenic tanking operations to begin as today's Atlas V countdown proceeds on schedule to launch the ViaSat-3 F2 satellite at 10:16 p.m. EST (0316 UTC). However, weather is currently red due to thick clouds.

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.
The United Launch Alliance Atlas V rocket is back atop Space Launch Complex-41 and poised for liftoff Thursday night to deliver the commercial ViaSat-3 F2 ultra-high-capacity broadband satellite into space. Liftoff is planned for 10:04 p.m. EST (0304 UTC) at the opening of a 44-minute launch window. The weather forecast is 95 percent favorable.ULA will provide countdown status in our live blog beginning at 7 p.m. EST (0000 UTC) and our launch webcast begins at L-20 minutes.bit.ly/av_viasat
ULA@ulalaunch·Countdown clocks have begun ticking at Cape Canaveral for tonight's Atlas V rocket launch carrying the ViaSat-3 F2 ultra-high-capacity broadband spacecraft. The booster vent valve in question during the earlier scrubs has been replaced and tested, and the team is proceeding with operations to launch one of the most sophisticated and powerful commercial communications satellites ever. Launch is planned for 10:04 p.m. EST (0304 UTC) at the opening of a 44-minute launch window.

When was the roll from the pad?
Both launch weather and space weather are GO for tonight's Atlas V rocket launch at 10:04 p.m. EST (0304 UTC), according to the day's first weather briefing by Space Force Launch Weather Officer Brian Cizak from the Space Launch Delta 45 weather squadron at Cape Canaveral.
ULA@ulalaunch·Good evening from Atlas V launch control at Cape Canaveral where our live blog has started for tonight's ViaSat-3 F2 mission. This is your official source for updates throughout the countdown to the 10:04 p.m. EST (0304 UTC) launch. http://bit.ly/av_viasat
Centaur LH2 loading beginsThe launch team has received the "go" to begin filling the Centaur upper stage with the super-cold liquid hydrogen fuel following chilldown of the system. The Centaur holds about 12,300 gallons of the cryogenic propellant.
Nov 13 17:51Centaur's liquid hydrogen tank is 40 percent full. The cryogenic propellant will be consumed with liquid oxygen by the stage's Aerojet Rocketdyne RL10C-1-1 engine.
Nov 13 17:57Engineers at the Atlas propulsion console here in the launch control room report that the new booster vent valve is functioning properly. The team just completed a successful cycle test that verified the hardware is operating as expected.
Nov 13 18:04Atlas V 551This is Atlas Launch Control with 60 minutes remaining until liftoff of Atlas V 551 rocket carrying ViaSat-3 F2 -- expected to be one of the most sophisticated and powerful communications satellites ever deployed. It is considered an engineering marvel.The Atlas V, designated AV-100, is a two-stage rocket that incorporates five GEM 63 solid rocket boosters, features a single RL10C-1-1 engine on the Centaur upper stage and encapsulates the spacecraft in a 5.4-meter-diameter (17.7-foot) payload fairing. It stands 196 feet (59.7 meters) tall and will leave the pad on 2.7 million pounds (12 megaNewtons) of thrust from the kerosene-fueled first stage main engine and solid motors.The Atlas V 551 is the highest performance configuration of the rocket family with a full complement of five solid rocket boosters. It first flew in 2006 and has launched the New Horizons spacecraft to Pluto, the Juno orbiter to Jupiter, a variety of national security and commercial missions.
