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.

It looks like a good day to go to space, and our Atlas V 551 rocket is targeting 10:24 p.m. EST (0324 UTC) tonight for ignition at Cape Canaveral.
ULA has initiated the launch countdown, a tightly scripted sequence of procedures and steps over the next seven hours that will complete pre-launch testing, fill the rocket with propellants and put systems into flight mode.
Tonight's mission will deliver the ViaSat-3 F2 satellite into orbit for an anticipated 15+ year lifespan.
