Another day, another scrub for the world's first 3D-printed rocket.
又是一天，世界上首枚3D打印火箭又一次取消发射了。
An attempt by a California-based aerospace startup Relativity Space to launch the world's first 3D-printed rocket on Saturday, failed to get off the ground after two launch attempts.
周六，总部位于加州的太空初创企业Relativity Space尝试发射世界上第一枚3D打印火箭，但在两次发射尝试后未能成功。
The 3D-printed rocket, called Terran 1, was scheduled to launch on a debut flight from Launch Complex 16 at Cape Canaveral Space Force Station in Florida during a three-hour window on Saturday afternoon.
这枚3D打印的火箭名为“人族1号”，计划于周六下午在佛罗里达州卡纳维拉尔角太空部队基地的16号发射场进行试射，有3小时的发射窗口。
It was slated to liftoff at 4 P.M., but with 45 seconds to go in the countdown, ground controllers called off the attempt.
该火箭原定于下午4点升空，但在倒计时还有45秒时，地面控制人员取消了这次试射。
Roughly an hour earlier, the rocket suffered a separate last-minute abort after the booster's engines had fired.
而大约一小时前，这枚火箭在助推器引擎点火后，在最后一刻出现了分离系统中止。
At one point during the three-hour launch window, the countdown was put on hold when a private boat violated a danger zone.
在3个小时的发射窗口期间，由于一艘私人船只闯入了禁区，倒计时曾一度被暂停。
An earlier scheduled launch last Wednesday was also postponed over last-minute propellant temperature issues.
而此前原定于上周三进行的该火箭的试射，也因推进剂温度问题而被推迟。
Terran 1 is not expected to carry a payload for its first flight, but the rocket will eventually be capable of putting up to 2,755 pounds into low Earth orbit.
“人族1号”的首次飞行预计不会携带有效载荷，但该火箭最终将能够将重达2755磅的载荷送入近地轨道。
The rocket is 110-feet tall with a diameter of 7.5 feet.
这枚火箭高110英尺，直径7.5达英尺。
While the rocket isn't completely 3D-printed, 85% of its mass is -- including the engines.
“人族1号”火箭并非完全由3D打印而成，而是85%的部位（包括发动机）是由3D打印制造的。
Provided it can get off the ground, Terran 1 would represent a significant milestone for spaceflight technology.
如果能离开地面，“人族1号”将是航天技术的一个重要里程碑。
In theory, Terran 1's manufacturing process produces a spacecraft that is cheaper and faster to make.
从理论上来讲，“人族1号”的制造过程，可以制造出成本更低、速度更快的航天器。
Relativity Space claims it can build a Terran 1 rocket in about 60 days, and that exclusive missions will cost around $12 million to complete.
Relativity Space公司声称，他们可以在大约60天内制造出一枚“人族1号”火箭，而完成这项独家任务将耗资约1200万美元。
