蚱蜢火箭
蚱蜢火箭（Grasshopper）或称草蜢火箭，是SpaceX公司开发的一种可回收的小型火箭。它同猎鹰9号火箭一样使用了默林火箭发动机。
其主要用途是测试猎鹰9号的回收模式以及通过飞行实验来收集数据。

WATCH: Grasshopper flies to its highest height to date - 744 m (2441 ft) into the Texas sky. http://youtu.be/9ZDkItO-0a4 This was the last scheduled test for the Grasshopper rig; next up will be low altitude tests of the Falcon 9 Reusable (F9R) development vehicle in Texas followed by high altitude testing in New Mexico.
