Space x launched it's grasshopper rocket over 325 m , or 1066 feet then it used it's full navigation sensor suite with the F9-R closed loop control
flight algorithms (whatever that means lol)to accomplish a precision landing
I thought it was very impressive the way it takes off and lands so perfectly back on the pad , and thought people would like to see the video..
The constant computation of mathematical adjustments of thrust to control this with such precision is simply a mind boggling accomplishment. The
elation those engineers would be feeling will give them so much drive to improve and refine.
To think this was done with so much balls and skill back in the moon landing days blows my mind even more.
