Good morning from Vulcan launch control at Cape Canaveral where our live mission blog has started. This is your official source for play-by-play updates throughout the countdown and flight of Vulcan's first heavy-lift mission for Amazon Leo.
The launch team just received a GO to begin fueling operations and today's countdown is progressing smoothly towards a planned launch at 12:11 p.m. EST (1711 UTC). https://t.co/mChVNb0aEc
We are less than four hours away from the Vulcan Leo 1 liftoff for Amazon.
Fueling of the Vulcan rocket is progressing as liquefied natural gas (LNG) and liquid oxygen flow into the booster stage and the Centaur V is receiving its flight supply of liquid oxygen. https://t.co/mChVNb0aEc
ULA propulsion console operators here at the Launch Control Center report that the Vulcan and Centaur V upper stages are fueled with cryogenic propellant and topping modes are engaged, giving us a 1.99-million-pound (903,500-kg) rocket for launch at 12:11 p.m. EST (1711 UTC) from Cape Canaveral Space Force Station, Florida. https://t.co/mChVNb0aEc
The launch of a United Launch Alliance Vulcan rocket carrying the Amazon Leo 1 mission is delayed due to a network communication issue between the ground equipment and the launch vehicle that requires reconfiguration that would extend the hold beyond the 29-minute launch window.
The next launch attempt will be on Sunday, Nov. 15 at 12:11:30 p.m. EST pending range approval. The vehicle and spacecraft remain healthy.
United Launch Alliance initiated the countdown for today's Vulcan Leo 1 launch. The weather forecast predicts better than a 95 percent chance of favorable conditions.
The 29-minute window opens at 12:32 p.m. EST (1732 UTC) for liftoff from Space Launch Complex-41 at Cape Canaveral.
Our live status blog begins at 7:15 a.m. EST (1215 UTC) and the launch webcast starts 20 minutes before liftoff time: https://t.co/mChVNb0aEc
Sisters Novitiate stand ready to smite all who dare oppose the God-Emperor. These warriors of unwavering faith, sacred purpose and righteous zeal, will bring his wrath to the unfaithful. Whilst yet to be accepted as full Sisters within the Adepta Sororitas, their station is no measure of their might.
The launch of a United Launch Alliance Vulcan rocket carrying the Amazon Leo 1 mission is delayed due to a power interruption in the Air Liquide gaseous nitrogen (GN2) plant which resulted in the loss of their high-pressure pumps. Without confirmation of sustained commodity flow, the team has decided to realign the launch to the back-up opportunity on Sat., Nov. 14 at 12:32:30 p.m. EST (1732:30 UTC). The vehicle and spacecraft are healthy.
