  • The space shuttle does not have "booster tanks." It carries an external tank (the orange one) plus two solid rocket boosters. The external fuel tank fuels the three main engines on the back of the space shuttle. Alone, the main engines give out a total power output of 1,987,500,000 Watts, giving the shuttle a maximum speed of 375 m/s. With the addition of the solid rocket boosters, the total power output would be 11,700,000,000 Watts and the average total velocity would be 740 m/s. The external tank is composed of the liquid oxygen and liquid hydrogen tank. The liquid O2 tank's volume is 19,563 cubic feet. It is 331 inches in diameter, 592 inches long and weighs 12,000 pounds empty. The liquid hydrogen tank is 331 inches in diameter, 1,160 inches long, and has a volume of 53,518 cubic feet and a dry weight of 29,000 pounds.
