A rocket made almost entirely of 3D-printed parts started its first flight late Wednesday but failed to reach orbit.
周三晚些时候，一枚几乎完全由3D打印部件制成的火箭开始了首次飞行，但未能进入轨道。
The 33-meter-long rocket, called Terran 1, took off from Cape Canaveral, Florida.
这枚名为人族1号的火箭长33米，从佛罗里达州的卡纳维拉尔角发射升空。
The startup company Relativity Space created 85 percent of the rocket using 3D printing technology.
初创公司Relativity Space使用3D打印技术制造了这枚火箭85%的零部件。
Most parts came from the company's large printing center in Long Beach, California.
大部分零件来自该公司位于加利福尼亚州长滩市的大型打印中心。
Terran 1 took off successfully and stayed in the air for three minutes.
人族1号成功起飞，在空中停留了3分钟。
The first stage, or lower part, of the rocket launched and separated as planned.
这枚火箭的第一级，即最下面一级，按计划发射和分离。
The upper stage, however, appeared to ignite and then shut down, sending it crashing into the Atlantic Ocean.
然而，上面的一级似乎被点燃了，然后关闭，致使其坠入大西洋。
Relativity Space had hoped for the rocket to stay in orbit for several days before falling through Earth's atmosphere and burning up.
Relativity Space曾希望这枚火箭在坠入地球大气层并烧毁之前在轨道上停留几天。
It was the second failed launch by Relativity Space this month.
这是Relativity Space本月第二次发射失败。
The company called off an attempt 12 days ago just seconds before takeoff.
12天前，就在火箭起飞前的几秒钟，该公司取消了那次尝试。
Though the rocket did not reach orbit, the company said it was pleased with the launch.
虽然火箭没有进入轨道，但该公司表示，它对这次发射感到满意。
Arwa Tizani Kelly works for Relativity Space and discussed the launch.
阿尔瓦·替扎尼·凯利在Relativity Space工作，他讨论了这次发射。
Kelly said that "(first) launches are always exciting and today's flight was no exception."
凯利说：“（第一次）发射总是令人兴奋的，今天的飞行也不例外。”
Although other space businesses use 3D-printed materials, the pieces make up only a small part of their rockets.
虽然其他太空企业使用3D打印材料，但这些材料只占他们火箭的一小部分。
Relativity Space was founded in 2015 by two young engineers.
Relativity Space是由两名年轻的工程师于2015年创立的。
The company said it is working to develop larger versions of the rocket that will have even more 3D-printed material.
该公司表示，其正在努力开发更大版本的火箭，这种火箭将会使用更多3D打印材料。
