SpaceX Transporter-18 任务发射预览：超百颗卫星搭乘猎鹰9号升空
Launch preview: More than 100 spacecraft hitch a ride to orbit on SpaceX’s Transporter-18
SpaceX 将于周四下午从范登堡太空军基地执行 Transporter-18 任务，使用 B1082 助推器搭载近 7.5 分钟后的着陆回收。该任务将把 Google AI 原型、甲烷追踪器等 130 个有效载荷部署至极地轨道。此次发射是 SpaceX 当日第二次飞行，紧随 Crew-13 任务之后。
An artificial intelligence prototype from Google, a methane-tracker, pharmaceutical manufacturing labs, and more are hitching a ride onboard a SpaceX Falcon 9 rocket flying from Vandenberg Space Force Base on Thursday afternoon.
The Transporter-18 mission is SpaceX second launch of the day, following the successful flight of NASA’s SpaceX Crew-13 mission from Florida.
Liftoff from Space Launch Complex 4 East is scheduled for 11:32 a.m. PDT (2:32 p.m. EDT / 1832 UTC). The rocket will head off on a southerly trajectory upon leaving the pad.
Spaceflight Now will have live coverage beginning about 30 minutes prior to liftoff.
SpaceX will launch the mission using the Falcon 9 booster with the tail number B1082. This will be its 25th flight following the launches of NROL-145, USSF-62, and OneWeb Launch 20, and 21 batches of Starlink satellites.
Nearly 7.5 minutes after liftoff, B1082 will target a landing back at Landing Zone 4. This will be the 36th landing at this site and 665th landing of a Falcon booster to date.
The 130 payloads will be deployed into a polar orbit of the course of 11 minutes starting about 54 minutes into the flight.
