the Head of SpaceX issued a new batch of details regarding the rocket, designed to fly to Mars. Earlier it was reported that its diameter will be 12 meters, and she will be equipped with 42 engines. But as it turned out, the plans of the developers has changed, and with them has changed and the rocket.

compared to the dimensions of the missile was much «slimmer» and sleeker. In his Twitter Elon Musk said that now the diameter of the rocket will be the whole 9 yards, engines will be not 42, and 21. This means that control of the missile will be much easier.

Nine metres in diameter — is a lot. The diameter of Falcon 9, SpaceX is now used, is 3.7 meters. But the penalty of the rocket, we can continue to build on existing factories, whereas for rockets with a diameter of 12 meters would have to either build a new plant or to renovate old ones. In addition, the diameter reduction and the cheaper designs will allow SpaceX to bring to the new missile the attention of customers, including military, as well as provide a greater number of orders.
