Update on ViaSat-3 F2 Mission Launch by ULA
The United Launch Alliance (ULA) scrubbed tonight’s launch of the Atlas V rocket carrying the ViaSat-3 Flight 2 (F2) mission due to an issue with the booster’s liquid oxygen tank vent valve during final checkouts.
Launch Delay and Troubleshooting
Additional time is needed for troubleshooting, and ULA is preparing for a 24-hour recycle of the launch attempt. The mission will lift off from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.
The new launch window is planned for Thursday, November 6, at the start of a 44-minute window.
Mission Details and Preparations
The Atlas V’s first stage was loaded with room-temperature RP-1 propellant, which powers the main engine during initial flight. Cryogenic loading of liquid hydrogen and liquid oxygen is scheduled during the final countdown hours.
Weather Conditions
Weather forecasts predict a 95% chance of favorable conditions at launch, although officials continue to monitor potential concerns regarding the Cumulus Cloud Rule.
“Today’s forecast shows a 95 percent chance of favorable weather conditions for launch.”
Everything is progressing as planned while ULA prepares for the updated launch date.
Author's summary: The ViaSat-3 F2 mission launch by ULA was delayed due to a technical issue but remains on track with high chances of favorable weather for the rescheduled launch on November 6.
