The next opportunity could come on Tuesday (Dec. 12).

下一个机会可能会在周二（12 月 12 日）到来。

We'll have to wait at least one more day to see SpaceX's powerful Falcon Heavy rocket take to the skies again.

我们至少还要再等一天才能看到 SpaceX 强大的猎鹰重型火箭再次升空。

The brawny Falcon Heavy had been scheduled to launch the U.S. Space Force's robotic X-37B space plane from Florida on Monday night (Dec. 11), a liftoff known as USSF-52. But about 30 minutes before the planned 8:24 p.m. EST (0124 GMT) liftoff time, SpaceX announced a scrub.

强大的猎鹰重型火箭原定于周一晚上（12 月 11 日）从佛罗里达州发射美国太空军的机器人 X-37B 太空飞机，这次升空被称为 USSF-52。但距离计划的晚上 8 点 24 分还有大约 30 分钟。美国东部时间 (0124 GMT) 升空时间，SpaceX 宣布进行擦洗。

"Standing down from tonight’s Falcon Heavy launch due to a ground side issue; vehicle and payload remain healthy. Team is resetting for the next launch opportunity of the USSF-52 mission, which is no earlier than tomorrow night," SpaceX wrote via X (formerly known as Twitter).

USSF-52 will be the seventh launch for the reusable, 29-foot-long (8.8 meters) X-37B, which military officials say is primarily a testbed for new instruments and other technologies. Most payloads and other details about X-37B missions are classified.

USSF-52 将是可重复使用、长 29 英尺（8.8 米）的 X-37B 的第七次发射，军方官员表示，X-37B 主要是新仪器和其他技术的测试平台。有关 X-37B 任务的大多数有效载荷和其他详细信息都是保密的。

The first five X-37B missions launched atop United Launch Alliance Atlas V rockets. The most recent one, which landed in November 2022 after 908 days in orbit, lifted off atop a SpaceX Falcon 9.

前五次 X-37B 任务是在联合发射联盟 Atlas V 火箭上发射的。最近的一次是在轨道上运行 908 天后于 2022 年 11 月着陆，由 SpaceX 猎鹰 9 号火箭升空。

USSF-52 will be the first X-37B mission to ride atop a Falcon Heavy, which can take the space plane higher than it has ever gone before. And that may indeed happen; the goals of the coming mission "include operating in new orbital regimes, experimenting with space domain awareness technologies and investigating the radiation effects to NASA materials," Space Force officials wrote in a release last month.

USSF-52 将是第一个搭载猎鹰重型飞机的 X-37B 任务，这可以让这架太空飞机达到前所未有的高度。这确实可能发生；太空部队官员在上个月的一份新闻稿中写道，即将到来的任务的目标“包括在新的轨道状态下运行、试验太空领域感知技术以及调查对美国宇航局材料的辐射影响”。

That NASA radiation experiment will expose plant seeds to the harsh environment of space, the release added.

新闻稿补充说，美国宇航局的辐射实验将使植物种子暴露在恶劣的太空环境中。

The Falcon Heavy debuted in February 2018, on a highly anticipated test flight that sent SpaceX founder and CEO Elon Musk's red Tesla Roadster into orbit around the sun.

猎鹰重型火箭于 2018 年 2 月首次亮相，进行了一次备受期待的试飞，将 SpaceX 创始人兼首席执行官埃隆·马斯克 (Elon Musk) 的红色特斯拉跑车送入绕太阳轨道。

The heavy lifter has flown eight times to date, including four times this year already. The rocket last flew in October of this year, when it launched NASA's Psyche asteroid probe.

到目前为止，这位举重运动员已经飞行了八次，其中今年已经飞行了四次。这艘火箭最后一次飞行是在今年 10 月，当时它发射了美国宇航局的普赛克小行星探测器。

The X-37B Falcon Heavy launch was originally supposed to happen on Sunday (Dec. 10), but SpaceX pushed the liftoff back a day due to weather concerns. 

X-37B 猎鹰重型火箭原本定于周日（12 月 10 日）发射，但由于天气原因，SpaceX 将发射推迟了一天。
