The agency recently announced its new deorbiting plan for the ISS after considering other options to retire it.

在考虑了退役国际空间站的其他选择后，该局最近宣布了其新的国际空间站脱轨计划。

NASA has said a deorbiting operation would begin by slowing lowering the ISS' altitude level.

NASA表示，脱轨操作将从减缓国际空间站的高度开始。

The agency said the deorbiting operation will take place sometime after the station's " operational life, " which has been set for 2030.

该机构表示，脱轨操作将在空间站“运行寿命”（预定为2030年）之后的某个时候进行。

It says it can be a completely new vehicle or an existing design that is changed to meet all needs of the deorbiting process.

美国宇航局称它可以是一种全新的载运工具，也可以是一种现有的设计，可以进行改造以满足脱轨过程的所有需求。

Some companies worry that deorbiting the entire station would be a waste, and that some of its modules and resources could be repurposed or reused in space.

一些公司担心让整个空间站脱离轨道是一种浪费，而且它的一些模块和资源可以在太空中重新利用或重复使用。

In a statement, NASA said it chose the method of deorbiting with a specially designed vehicle to provide a " safe and responsible deorbit of the ISS in a controlled manner."

NASA在一份声明中表示，它选择了使用专门设计的飞行器脱轨的方法，是为了“以可控的方式安全、负责地脱离国际空间站”。
