November 14 Update: Computer Glitches Cause Another Day Delay

Early Saturday morning, ULA released the following statement:

“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 are healthy.”

Social media quickly added some humor to the situation. Delays are a normal part of spaceflight, and you may as well laugh at them when they happen.

November 14 Update: Commodities Delivery Issue Forces Delay

United Launch Alliance announced a one-day delay to the planned launch of the Amazon Leo 1 mission aboard a Vulcan VC6L. They cited delays at the Air Liquide plant on Courtenay (SR3), which interrupted commodity liquid nitrogen delivery to SLC-41 and, ultimately, to Vulcan. The delay gives crews time to reset the pipeline properly, and with no other issues, Vulcan will launch tomorrow afternoon.
