跟进：ULA 火神火箭连续第二天取消发射，地面通信问题待修，改期美东周日12时11分
联合发射联盟（ULA）11月14日上午宣布，火神（Vulcan）火箭原定当天美东中午12时32分在佛罗里达州 Cape Canaveral 太空军基地 41 号发射场升空的尝试再次取消：地面设备与火箭之间出现网络通信问题，发射改期美东周日11月15日中午12时11分（美西上午9时11分），火箭与所载的 40 颗 Amazon Leo 宽带卫星状态良好。
ULA 在官方推文中表示，这处通信问题需要重新配置，所需时间将超出当天 29 分钟的发射窗口，因此周六上午决定取消。这与周五取消的原因不同：周五是在加注推进剂期间，Air Liquide 气态氮工厂断电、高压泵停转，倒计时被叫停。
这次任务编号 LV-01，是火神火箭今年 2 月 12 日一枚固体助推器喷管在升空后出现异常以来首次飞行，也是它第一次为 Amazon 发射卫星。这枚火箭采用六枚固体助推器的构型，高 215 英尺，按计划沿东北方向飞行，把 40 颗 Amazon Leo 卫星送入近地轨道。
ULA 表示，火箭与航天器保持健康状态。周日的发射窗口同样为 29 分钟，自美东中午12时11分开启；若顺利升空，这将是火神在喷管设计与制造改进之后的第一次真实飞行检验。

Follow-up: ULA Vulcan Launch Scrubbed for a Second Straight Day Over a Ground Communication Issue, Reset for Sunday 12:11 p.m. ET
United Launch Alliance (ULA) announced on the morning of November 14 that the Vulcan rocket's planned launch that day, set for 12:32 p.m. Eastern from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida, was scrubbed again: a network communication issue developed between the ground equipment and the launch vehicle. Liftoff is now reset for 12:11 p.m. Eastern on Sunday, November 15 (9:11 a.m. Pacific), and the rocket and its 40 Amazon Leo broadband satellites remain healthy.
In an official post, ULA said the communication issue requires a reconfiguration that would extend the hold beyond the day's 29-minute launch window, leading to Saturday morning's decision. The cause differs from Friday's scrub, which came during propellant loading when a power interruption at the Air Liquide gaseous nitrogen plant took its high-pressure pumps offline and halted the countdown.
The mission, designated LV-01, is Vulcan's first flight since a solid rocket booster nozzle anomaly shortly after liftoff on February 12, and its first launch for Amazon. Flying with six solid rocket boosters and standing 215 feet tall, the rocket is to head northeast and deploy 40 Amazon Leo satellites into low Earth orbit.
ULA said the rocket and spacecraft remain healthy. Sunday's launch window is also 29 minutes, opening at 12:11 p.m. Eastern; a successful liftoff would be the first in-flight test of Vulcan's redesigned and reworked booster nozzle.
