SpaceX Starship has goal reusable launch vehicle
Design
When stacked and fully fueled, Starship has a mass of approximately 5,000 t (11,000,000 lb) , a diameter of 9 m (30 ft), and a height of 120 m (390 ft), though the height of the vehicle is expected to rise to 122 m (400 ft) due to the addition of a venting ring, which will be necessary for the hot staging of the vehicle. While the current prototype versions of Starship are not reused, the rocket has been designed with the goal of being fully reusable to reduce launch costs and maintenance between flights. In its fully reusable configuration Starship is designed to carry up to 150 t (330,000 lb) to low Earth orbit, while the expended configuration is projected to have a payload capacity of up to 250 t (550,000 lb).The rocket consists of the Super Heavy first-stage or booster, and the Starship second-stage or spacecraft, powered by the Raptor and Raptor Vacuum engines. The bodies of both rocket stages are made from stainless steel, giving Starship its strength for atmospheric entry and distinctive look.According to Eric Berger of Ars Technica, the manufacturing process starts with rolls of steel, which are unrolled, cut, and welded along the cut edge to create a cylinder of 9 m (30 ft) in diameter, 2 m (7 ft) in height, and 4 mm (0.16 in) thick, and around 1,600 kg (4,000 lb) in mass. These cylinders, along with the nose cones, are stacked and welded along their edges to form the outer layer of the rocket. Inside, the methane and oxygen tanks are separated by the robot-made domes. Also according to Berger, Starship's reusability and stainless-steel construction has influenced the Terran R rocket and Project Jarvis, the second stage of Blue Origin's New Glenn super heavy-lift launch vehicle.
