Liquids are desirable because their reasonably high density allows the volume of the propellant tanks to be relatively low, and it is possible to use lightweight centrifugal turbopumps to pump the propellant from the tanks into the combustion chamber, which means that the propellants can be kept under low pressure. This permits the use of low-mass propellant tanks, resulting in a high mass ratio for the rocket. ]]> 2016-09-12 18:30:15 UTC https://padlet.com/thebug02hclc/jhx7u1hf7bx3/wish/123257302 andrew_l_jones11 https://padlet.com/thebug02hclc/jhx7u1hf7bx3/wish/123257643 The external tank held 143,000 gallons of liquid oxygen (1,359,000 pounds) and 383,000 gallons of liquid hydrogen (226,000 pounds). The fuel weighed almost 20 times more than the Shuttle. At launch, the Shuttle, external tank, solid rocket boosters and all the fuel combined had a total weight of 4.4 million pounds.]]> 2016-09-12 18:31:05 UTC https://padlet.com/thebug02hclc/jhx7u1hf7bx3/wish/123257643 elliottpippin https://padlet.com/thebug02hclc/jhx7u1hf7bx3/wish/123258470 Harambe=Elliott
