KIDS TRIVIA

Detailed explanation-1: -The external tank of the shuttle carries about 384, 071 gallons (227, 800 pounds) of liquid hydrogen, but about 628, 540 gal-lons (372, 800 pounds) are used in all during shuttle vehicle loading.

Detailed explanation-2: -The boosters contribute to the power that SLS needs to launch payloads with more mass and volume to deep space than any rocket ever built. This makes it possible to send astronauts to distant destinations including Mars.

Detailed explanation-3: -The rocket’s main engines use a combination of liquid hydrogen and liquid oxygen. Hydrogen has the lowest molecular weight of any known substance, making it ideal for keeping the weight of a rocket relatively small. When combined with liquid oxygen, hydrogen creates the most efficient thrust of any rocket propellant.
