The Beijing-based private space company i-Space used its own SQX-1Z carrier rocket to place three satellites into space last Wednesday, marking China's first satellite launch by a privately¹ built rocket.

上周三，北京一家民营航天企业i-Space，使用其自主研制的SQX-1Z运载火箭，将三颗卫星送入太空，这标志着我国首次利用民企制造的火箭发射卫星。

The mission, termed by many industry observers as a landmark² in the country's space industry, was conducted at the Jiuquan Satellite Launch Center in northwestern China, which marked the first time that a private rocket blasted off from a government-run space launch site.

此次发射任务是在我国西北部的酒泉卫星发射中心进行的，多位业内观察人士称之为国内航空工业的一个里程碑事件，这是民营火箭首次在政府运营的航天发射场发射升空。

Developed and produced by i-Space, a Beijing space startup founded by a group of senior Chinese rocket scientists, the 9.5-meter SQX-1Z solid-propellant carrier rocket roared into the clear sky from a supporting pad from a large desert.

i-Space是由一群中国资深火箭专家成立的航天创业公司。由该公司开发和生产的SQX-1Z是一枚固体亚轨道探空火箭，全长9.5米，是从一个大沙漠的支承垫块上轰鸣升空。

According to i-Space, the rocket flew for more than 460 seconds and reached 108 kilometers above the ground before releasing three mini satellites.

据i-Space透露，当天这枚火箭飞行了超过460秒，升空高度达到108公里，之后将三颗微型卫星送入太空。

The satellites -- one from ZeroG Lab, a privately owned satellite maker³ in Beijing, and two from ADA-Space, a private firm in Chengdu specializing in satellite design and data services -- would travel in sub-orbit for an undisclosed period of time for technological⁴ demonstration⁵ and would then fall back to the land to be recovered, the company said in a statement.

i-Space在一则声明中称，这三颗卫星--一颗来自民营卫星制造商北京零重空间技术有限公司，两颗来自民营卫星设计和数据服务专业化企业成都国星宇航科技有限公司，将在亚轨道进行技术验证飞行，后着陆回收，星际荣耀并未披露此次飞行的持续时间。

The launch has been the third time for Chinese private enterprises to carry out space mission and also the second flight by the i-Space rocket family.

这次发射是中国民营企业第三次执行太空任务，也是i-Space火箭家族的第二次飞行。

The company performed its debut⁶ launch in April at a research rocket testing site in the island province of Hainan, verifying the design and equipment of the firm's first product, the indigenously⁷ developed SQX-1S.

今年4月份，该公司在海南省的一个研究火箭试验场进行了首次发射，验证了该公司第一批产品的设计和设备，即自主开发的SQX-1S。
