Cruise ship under rocket’s flight path forces another SpaceX launch scrub

在火箭飞行航线下的一艘游轮迫使SpaceX的一次发射取消。

A cruise ship that ventured under the planned flight path of a Falcon 9 rocket near Cape Canaveral Sunday forced SpaceX to delay launch of an Italian Earth-imaging satellite for a fourth time, setting up the mission for another try just after sunset Monday.

周日，一艘游轮在卡纳维拉尔角附近冒险路过猎鹰9号火箭的预定飞行路线，迫使SpaceX公司推迟了第四次意大利地球成像卫星的发射，并将任务安排在周一日落后。

SpaceX was set to fire a Falcon 9 rocket into orbit from pad 40 at Cape Canaveral Space Force Station at 6:11 p.m. EST (2311 GMT), but the Coast Guard could not clear a cruise liner out of the rocket’s downrange hazard area in time for the mission’s instantaneous launch opportunity.

SpaceX原定于在美国东部时间下午6点11分（格林尼治时间23点11分）从卡纳维拉尔角太空部队基地40号发射台发射猎鹰9号火箭进入轨道，但在迎接任务的瞬间，海岸警卫队未及时将一艘游轮清理出火箭下的危险区域。

The launch director called a hold in the countdown at T-minus 33 seconds, and announced SpaceX’s launch team will try again Monday at the same time.

发射主管在倒数T-33秒时宣布停止发射，并宣布SpaceX的发射团队将在周一同一时间再次发射。

The last-minute hold marked the fourth delay for SpaceX’s mission to launch Italy’s newest COSMO-SkyMed radar remote sensing satellite. Bad weather prevented the Falcon 9 from taking off Thursday, Friday, and Saturday.

这是SpaceX公司第四次推迟发射意大利最新COSMO-SkyMed的雷达遥感卫星。恶劣的天气致使猎鹰9号无法在周四，周五和周六发射。

Weather conditions were chilly but ideal for launch Sunday. Similar conditions are forecast Monday evening, when there’s a 90% chance that winds and clouds will be acceptable for liftoff of the Falcon 9. The rocket’s reusable first stage will return to landing at Cape Canaveral about eight minutes after launch.

虽然天气寒冷，但周日的发射条件十分理想。周一晚预测有类似的天气条件，有90%的机会猎鹰9号可以在可接受的风和云的条件下升空。火箭可重复使用的第一级将在发射后8分钟左右返回卡纳维拉尔角。

SpaceX did not identify which cruise ship caused the delay Sunday. Cruise liners from Royal Caribbean and MSC Cruises departed Port Canaveral Sunday evening. The port is located just south of Cape Canaveral Space Force Station.

周日SpaceX并没有确认到是哪艘游轮造成了这次延误。皇家加勒比游轮和MSC游轮于周日晚上驶离卡纳维拉尔港，其位于卡纳维拉尔角太空部队站的正南方。

The COSMO-SkyMed radar satellite will join a fleet of remote sensing spacecraft monitoring shipping traffic, natural disasters, and climate change for the Italian military and the Italian Space Agency. SpaceX will launch the 4,850-pound (2.2-metric ton) satellite into a polar orbit, requiring the Falcon 9 to fly south from Cape Canaveral, rather than the east or northeast corridors used by most rockets departing Florida.

COSMO-SkyMed雷达卫星将加入遥感航天器舰队，为意大利军方以及航天局监测航运交通，自然灾害和气候变化。SpaceX将把这颗重达4850磅（2.2公吨）的卫星发射到极地轨道，则需猎鹰9号于卡纳维拉尔角向南飞行，而不是同大多数离开佛罗里达州的火箭一样使用东部或东北部航道。

In 2020, SpaceX launched the first polar orbit mission from Cape Canaveral since 1969. The COSMO-SkyMed mission will be the fifth polar orbit mission launched by SpaceX since then, and the second this month, as the southerly launch corridor gains more use.

2020年，SpaceX于卡纳维拉尔角发射了自1969年以来的第一次极地轨道任务。COSMO-SkyMed任务将是SpaceX自1969年来发射的第五次极地轨道任务，也是本月发射的第二次极地轨道任务，而向南的发射航道使用更高。

The launch hazard area for ships and aircraft is different for a polar orbit launch than a launch to the east or northeast, such as flights heading to the International Space Station.

在极地轨道发射卫星时，船舶和飞机发射危险区域与向东方或东北方向发射时不同，如飞往国际空间站的卫星。

The launch attempt Monday will be the last for the COSMO-SkyMed mission before SpaceX turns its attention to a higher-priority launch from Vandenberg Space Force Base in California for the National Reconnaissance Office, the U.S. government’s spy satellite agency.

周一的此次尝试发射将是COSMO-SkyMed任务的最后一次，在此之前，SpaceX会将注意力转移到更适宜的加利福尼亚州范登堡太空部队基地为美国政府的间谍卫星机构国家侦察办公室而进行的发射上。

The scrubbed launch attempt Sunday will also cause a delay in SpaceX’s next Starlink satellite deployment mission, which was set to take off Monday from pad 39A at NASA’s Kennedy Space Center, a few miles north of Cape Canaveral Space Force Station.

周日取消的尝试发射还将推迟SpaceX的下一次Starlink卫星部署任务，其原定于周一于NASA肯尼迪航天中心39a号发射台起飞，发射台位于卡纳维拉尔角太空部队基地以北几英里处。

A new target launch date for that mission was not available late Sunday. It will carry 49 more satellites into orbit for SpaceX’s privately-developed internet network.

周日晚些时候，这项任务新目标的发射日期还未公布。它将携另外49颗卫星进入轨道，这将用于SpaceX私人开发的互联网网络。
