justin bachman who covers a space industry for us, now justin, how significant is this milestone?ink is fairly significant. you are seeing spacex learning they fly a lot, they will learn a lot. one of the questions the company has to be, what is the minimal amount that is required to have a safe light only for the payload, buffer customer payloads? the faster you can do that -- but also customer payloads, the faster you can do that this is a business more than a novelty. when you make it a business you are always looking to lower cost and this is an important part of this. how quickly can you flight, today they are taking a payload that will contribute to their constellation, that is more money. it is a business that works and i think we are emily: we are about 30 seconds away from the first stage main engine getting cut off here. i would like to talk about how this fits into the bigger mission of elon musk and spacex. the goal is to have these taking off as frequently as airplanes take off on earth. can you paint a picture for us of what this future space economy will look like?
