Rocket man. If humans are ever going to make to Mars, we need a really big, really powerful rocket ship, which is what Elon Musk’s SpaceX is building. Formerly known as BFR, the Starship has the size and power to, well, make it to distant planets and beyond. A little while back Musk shared a 3D render of the ship that made it look like something straight out of a 1950’s sci-fi magazine. More recently, he revealed a smaller, suborbital version that they’ll use for tests. Judging by the human standing underneath it, it’s still pretty darn big.
