This test-firing may not match the flame of earlier demonstrations, but SpaceX CEO Elon Musk tweeted out a brief eight-second video of another setup it's testing, the "Grasshopper" reusable vertical takeoff, vertical landing rocket. While the first hop would've been shamed in any interstellar dunk contest, future tests will range in height from a few hundred feet to two miles. The goal is to eventually create a reusable first stage for its Falcon 9 rocket, able to land safely instead of crashing into the sea and damaged beyond repair.
