在这张照片中,一名球形航空航天工程师正在对飞船进行最后的检查,之后飞船将被送往位于佛罗里达州的NASA肯尼迪航天中心进行发射处理。GPIM是2019年6月SpaceX猎鹰重型运载火箭搭载美国空军空间和导弹系统中心空间测试项目2 (STP-2)执行的四项独特的NASA技术任务之一。

A small spacecraft the size of a mini-refrigerator is packed with cutting-edge “green” technology. NASA’s Green Propellant Infusion Mission, or GPIM, will prove a sustainable and efficient approach to spaceflight. The mission will test a low toxicity propellant and compatible systems in space for the first time. This technology could improve the performance of future missions by providing for longer mission durations using less propellant.

In this photo, a Ball Aerospace engineer performs final checks before the spacecraft shipped to NASA’s Kennedy Space Center in Florida for launch processing. GPIM is one of four unique NASA technology missions aboard the June 2019 SpaceX Falcon Heavy launch of the U.S. Air Force Space and Missile Systems Center’s Space Test Program-2 (STP-2).
