跟进：ULA火神火箭成功升空复飞，载40颗Amazon Leo卫星，六枚助推器顺利抛离
联合发射联盟（ULA）的火神（Vulcan）火箭于美东时间11月15日中午12时40分在佛罗里达州 Cape Canaveral 太空军基地41号发射场升空，载着40颗 Amazon Leo 宽带卫星沿东北方向飞向近地轨道。这是火神火箭今年2月12日一枚固体助推器喷管在升空后出现异常、停飞九个月以来的首次飞行，任务编号 LV-01。
升空后1分45秒，ULA 通报六枚固体助推器已在约22英里高度全部抛离，火箭继续飞行。本次发射窗口为美东中午12时11分至12时40分，当天倒计时一度因故暂停，发射团队处理后把升空时刻定在窗口末端的12时40分，前两天（11月13日、14日）的两次尝试则先后因氮气供应断电与地面通信问题取消。
这枚火箭采用 VC6L 构型：近地轨道优化的 Centaur V 上面级、六枚侧挂固体助推器与加长型整流罩，整流罩长70英尺。ULA 表示，这是 Amazon 向 ULA 订购的38次火神发射中的第一次，此前 Amazon Leo 已由 Atlas V 火箭完成八次部署任务；Amazon Leo 星座初期将由3,000多颗卫星组成，为现有网络覆盖不到的地区提供宽带服务。
按飞行程序，Centaur V 上面级将在升空约70分钟后开始释放40颗卫星，整个部署过程约25分钟。本稿发稿时部署尚未开始，部署结果将以跟进稿续报。

Follow-up: ULA Vulcan Lifts Off on Return-to-Flight Mission With 40 Amazon Leo Satellites, All Six Boosters Away Cleanly
United Launch Alliance's Vulcan rocket lifted off at 12:40 p.m. Eastern on November 15 from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida, carrying 40 Amazon Leo broadband satellites on a northeasterly trajectory toward low Earth orbit. The flight, designated LV-01, is Vulcan's first since a solid rocket booster nozzle anomaly shortly after liftoff on February 12 grounded the rocket for nine months.
One minute and 45 seconds into flight, ULA reported that all six solid rocket boosters had been jettisoned at an altitude of about 22 miles, with the rocket continuing on its way. The day's launch window ran from 12:11 p.m. to 12:40 p.m. Eastern; the countdown was held once during the count before the team reset liftoff to the end of the window at 12:40 p.m. Attempts on November 13 and 14 had been scrubbed, first over a gaseous nitrogen supply power outage and then over a ground communication issue.
The rocket flew in the VC6L configuration: a low Earth orbit-optimized Centaur V upper stage, six side-mounted solid rocket boosters and a longer-length payload fairing 70 feet long. ULA says this is the first of 38 Vulcan launches Amazon has booked with the company, following eight successful Amazon Leo deployment missions on Atlas V. The initial Amazon Leo constellation will include more than 3,000 satellites delivering broadband to areas beyond the reach of existing networks.
Under the flight profile, the Centaur V is to begin releasing the 40 satellites about 70 minutes after liftoff, over a deployment sequence of about 25 minutes. Deployment had not yet begun at the time of this report and will be covered in a follow-up.
