Changes to SpaceX's BFR spacecraft headed for Mars

The video tutorial discusses SpaceX's new spaceflight system, which includes a spaceship and a rocket booster. The system stands 118 meters tall, 11% taller than previous designs. SpaceX plans to use 7 Raptor engines instead of 6 for the BFR spaceship. The spaceship will feature two movable fins near its nose and two larger fins near its tail to aid in maneuverability. Elon Musk explains that these changes will help the vehicle land safely, using a vertical landing technique similar to a skydive.
